**PART
      I**


**Item
      1. Business**





***General*** ****





Rotoblock
      Corporation was incorporated in the State of Nevada on March 22, 2004. We were
      formed to engage in the development and licensing of an Oscillating Piston
      Engine (OPE) and are currently in the development stage. We have not yet
      generated any revenues since inception and have incurred net operating losses
      of
      $4,045,615, since inception. We do not own any real estate. Our auditors have
      raised substantial doubt about our ability to continue as a going concern.





We
      maintain our statutory registered agent's office in Carson City, Nevada and
      our
      business offices and testing laboratory in Santa Rosa, California.





***Acquisition
      of Patented Rights and Technology***





On
        March
        30, 2004, we acquired Rotoblock, Inc., a privately-held Canadian corporation
        (the Subsidiary), which holds an option entitling it to acquire all of the
        rights, title and interest in and to a patented technology and prototype
        engine
        in exchange for 15,000,000 shares of our restricted common stock, valued
        at $0.001 per
        share. The terms of the option are as follows:





For
      a
      consideration of US$100,000, plus interest at the rate of 24% per annum
      calculated from January 31, 2004 to the date of payment, paid on May 31, 2004,
      the inventor and an unrelated third party, Dr. Monti Farrell granted us, through
      our wholly-owned Subsidiary, Rotoblock, Inc., an option to acquire the patent
      rights to the engine technology. The option grants us the rights to further
      develop, market and sell the final engine product or to license the technology
      to third-party manufacturers. In addition, the option grants us the right and
      option to purchase the patents for US$1,000,000, if purchased by December 2,
      2005 (not paid), or for $1,500,000, if purchased within 36 months after payment
      of the initial deposit (June 2, 2007).




Dr.
      Farrell passed away during the year ended April 30, 2005 and the option rights
      were assigned to his Estate.





We
      currently do not own the patents or rights underlying the patents, but rather,
      have been granted the use thereof and an option to purchase the rights within
      3
      years, which gives us ample time to further test and develop the technology
      and
      engine. Pursuant to the terms of the agreement, the option may also be assigned
      to a third party without consent of the Estate of the Optionor.





We
      acquired all of the issued and outstanding shares of Rotoblock Inc. by issuing
      15,000,000 shares of our common stock. Since the transaction resulted in the
      former shareholders of Rotoblock Inc. owning all of the issued shares of
      Rotoblock Corporation, the transaction has been treated for accounting purposes
      as an acquisition by Rotoblock Inc. of the net assets and liabilities of
      Rotoblock Corporation. Under this purchase method of accounting, the results
      of
      operations of Rotoblock Corporation are included in the consolidated financial
      statements.





Rotoblock
      Corporation had a net asset deficiency at the acquisition date, therefore,
      the
      15,000,000 common shares issued on acquisition were issued at a fair value
      of
      $Nil with the net asset deficiency of $138 charged to deficit. Rotoblock Inc.
      is
      deemed to be the purchaser for accounting purposes. Accordingly, its net assets
      are included in the consolidated balance sheet at their previously recorded
      amounts.





All
      of
      our operations relating to the development and marketing of the OPE technology
      are conducted by Rotoblock, Inc. (the Subsidiary). We are currently in the
      process of improving on the technology to make the engine more efficient,
      economical and environmentally friendly in an effort to make it attractive
      to
      engine manufacturers to either acquire the technology or negotiate license
      agreements to use the technology. We have made several changes to the prototype
      engine. All parts except the crankshaft and engine block have been re-designed.





We
      are
      continuing our research, development and testing efforts until we are certain
      we
      have completed the best, most efficient model. This goal will be considered
      to
      be reached when the engine demonstrates a power to weight ratio of 2:1. We
      are
      hopeful this can be achieved within the 36 months granted in the option to
      use
      the technology underlying the patents.





**The
      Oscillating Piston Engine Technology (OPE)**





The
      OPE
      patented internal combustion engine is different than conventional reciprocating
      engine technology in that the current oscillating piston design incorporates
      four pairs of pistons. Each of these eight pistons is alternately attached,
      through two oppositely rotating adjacent discs, to two coaxial drive shafts
      extending from the center of one face of the cylinder block. Each piston is
      attached to a single disc such that four non-adjacent pistons are rigidly
      affixed to the upper disc and the remaining four to the lower. Each concentric
      shaft is attached, respectively, to the connecting discs. The discs, in turn,
      couple the motion of the oscillating pistons to a single crankshaft, via a
      dual
      scotch yoke mechanism. Each piston is a segmented toroidal section traveling
      within the closed toroidal chamber of the cylinder block.






3





The
      round
      cylinder block containing the pistons, connecting discs and coaxial output
      shafts is free to continuously rotate in a counter clockwise direction. It
      is
      caused to revolve ninety degrees for every complete revolution of the rotating
      crankshaft. This action is accomplished by a four-to-one ratio gear reduction
      mechanism which couples the two components together.





Rotation
      of the cylinder block causes a pair of intake and exhaust ports, as well as
      two
      diametrically positioned spark plugs, to regularly appear in the intervening
      spaces formed between the faces of the pistons as they oscillate backwards
      and
      forwards between the limits of allowed travel within the toroidal cylinder.
      When
      in operation, the diametrically opposed inlet ports in the cylinder block are
      supplied with a combustible fuel/air mixture through an attached intake
      manifold, such that the separating opposing piston pairs each draws in a fresh
      charge mixture as the rotating cylinder block passes through the first of four
      combustion cycles.





The
      second cycle begins as the same piston pairs reach their limits of travel,
      reverse direction and proceed to compress the charge mixture captured between
      their faces. Compression continues until the approaching piston faces reach
      their closest point at the end of their range of travel.





The
      third
      cycle starts with the appearance of the spark plugs in the intervening space
      between the moving pistons just at the point in the cycle when they make their
      closest approach to each other. At this juncture, timed firing of the spark
      plugs ignites the compressed charge mixture confined between the faces of each
      of the two piston pairs. The exploding fuel/air mixture is rapidly heated and
      expands, thereby forcing the opposing piston pair faces apart and, by so doing,
      produces the power cycle. The force applied to the separating pistons by the
      expanding gas is coupled, through the two connecting discs, to the scotch yokes,
      which, in turn cause the continuous rotation of the crankshaft and output
      shaft.




As
      the
      cylinder block continues to rotate, the fourth cycle begins. Next, exhaust
      ports
      appear between the piston pairs coincident with their change of direction at
      the
      end of the power stroke. The approaching piston faces now expel the burnt
      exhaust gases through the exhaust ports. This brings to a close the final cycle
      of the four cycle sequence.





The
      endless repetition of these four combustion cycles produces sixteen power
      strokes for each revolution of the cylinder block. Momentum stored in the
      inertial mass of the rotating cylinder block substitutes for the action of
      the
      flywheel found in conventional reciprocating engine designs.





***Simplicity
      of Design, Assembly and Repair***





The
      OPE
      engine is comprised of four major mechanical sub-assemblies. Each sub-assembly
      can be easily removed from the engine, allowing for rapid factory assembly
      and
      easy replacement or field servicing. We believe this feature should permit
      the
      engine to be totally field maintainable, to the degree that a major overhaul
      should be able to be completed by a qualified mechanic using only conventional
      hand tools in just a few hours. The simple design of the engine should also
      help
      reduce the costs of manufacturing because of the reduced parts count. In
      addition, the elimination of a valve train and liquid cooling system components
      in the oscillating piston engine design should lessen the engine's complexity,
      which could further reduce costs to achieve overall engine efficiency. We are
      currently still in the testing and development stages of the engine design
      and
      as a result, have not yet completed the final prototype for further
      testing.





Departure
      from conventional engine design, resulting in fewer moving parts, has allowed
      us
      to produce an engine with reduced frictional losses, which if proven in testing,
      could lead to increased reliability, improved performance and longer engine
      life. As is typical with mechanical systems, simplicity is the key to a
      successful design. In keeping with this philosophy, the OPE engine uses
      standardized components, common to the industry, wherever possible.





There
      is
      no certainty, however, that our research and development activities will result
      in a marketable engine that:





-
      can be
      assembled more quickly than a conventional engine;


-
      is
      easier to service in the field;


-
      is
      totally field maintainable; or


-
      will
      reduce the costs of manufacturing.





***Versatility
      of Use***





The
      OPE
      engine has been specifically designed to maximize versatility of use. The
      engine's extreme horsepower to weight ratio, when finally tested and proven,
      could lend itself useful to a wide variety of both industrial and consumer
      applications. The advantage of having high power-to-weight ratio and air-cooled
      design fits perfectly with the specialized requirements of many recreational
      vehicles and portable power tools. Here, engines in the range of several hundred
      to several thousand horsepower are employed to power electric generators, pumps
      and compressors, as well as a wide variety of other industrial and agricultural
      types of machinery. If we are successful in completing our proposed model and
      technology, it could be an ideal choice for applications such as
      these.





***Environmental
      Impact***





The
      OPE
      design is totally valve-less. As such, there are no moving intake or exhaust
      valves to limit combustion temperature, as with typical internal combustion
      engines. If we are successful in developing an operational engine on this basis,
      it would allow the engine to be operated with a leaner fuel/air mixture and
      a
      consequent higher combustion temperature. The result would be increased Carnot
      cycle efficiency


4


when
      used
      with gasoline or similar hydrocarbon fuels. Carnot cycle efficiency is the
      ratio
      of the output work to the input heat. Leaner mixture and higher combustion
      temperature promotes more complete oxidation of the burning fuel, which would
      reduce carbon monoxide emission, while increasing efficiency and reducing fuel
      consumption for a given equivalent power output. While there is no guarantee
      we
      will be successful in developing an operational engine on this basis, we will
      attempt to make the engine's environmental impact minimal.





***Research,
      Development and Testing Since Acquisition***





We
      have
      conducted a number of test runs with the engine and are continuing to improve
      upon the technology. The milestones we have set for ourselves have been reached
      and we are in the process of discussing potential joint ventures and/or
      co-development arrangements with qualified manufacturers. We are researching
      technologies that could be used in conjunction with the OPE, therefore enhancing
      the uses for this unique engine. The market has a need for technologically
      advanced and efficient propulsion systems, be they straight mechanical or hybrid
      in nature. One of the greatest challenges when incorporating hybrid technology
      into a vehicle is space limitation. Due to the projected high power-to-weight
      ratio of the OPE, at a given horsepower output OPE technology will result in
      a
      smaller, more compact engine, hence being ideally suited for such applications.
      We have also been contacted by manufacturers in the following areas who feel
      that the OPE exhibits attributes and characteristics that would benefit their
      product lines.

***Competition***





The
      industry in which we operate is intensely competitive with respect to new and
      evolving technologies on a continuous basis. In addition, there are many
      well-established competitors with substantially greater financial and other
      resources, including but not limited to established businesses with loyal
      customers. We will rely heavily on our new and developing engine technology
      to
      acquire a competitive edge. We have determined that some of our largest
      competitors will be Honda, Briggs & Stratton, Tecumseh, Kawasaki, Kohler and
      Stihl, the major producers of general purpose engines. Because of our intensive
      battle for market share among these companies, we will also be contacting these
      manufacturers anticipating that they will want to include our OPE technology
      in
      their product lines. There are always new and emerging technologies in the
      industry in which we compete; however, we are unaware of any other new types
      of
      engines being developed with our OPE products and technology will compete at
      this time.





***Marketing
      of Technology and/or Rights***





Our
      marketing efforts will be focused on selling manufacturing licenses or rights
      to
      use the technology. Sale of the technology rights would be preferred, as the
      administration and enforcement of licensing agreements can be very complex
      and
      costly.





The
      combustion engines we see today have experienced years of relentless
      development. Manufacturers have aimed to make engines more efficient, more
      durable, and in some cases lighter. Also, recently, great efforts are being
      made
      in reducing environmentally damaging emissions .





We
      consider it important that a new engine concept be introduced in a low-key
      manner and in applications that are not mission-critical in order to build
      a
      reputation of reliability over time. We intend to pursue a marketing strategy
      that primarily targets manufacturers of general purpose engines and secondarily,
      manufacturers of engines used in recreational vehicles, such as outboard motors
      and other weight critical uses. A review of the general purpose engine market
      is
      presently underway. To date it has been determined that several large companies,
      such as Honda, Briggs & Stratton, Tecumseh, Kawasaki, Kohler and Stihl,
      dominate the industry. Initially, we intend to focus our marketing efforts
      on
      these 6 largest manufactures of general purpose engines. The manufacturers
      produce engines for a large variety of applications, including portable chain
      saws, weeding machines, portable turbo generators, portable crushers, portable
      arc welders and generators, snow blowers, lawn mowers and air and gas
      compressors, among others.





Because
      of the anticipated high power to weight ratio and the intensive battle for
      market share, we are hopeful that we will be successful in convincing one or
      more of these and other not so well known small engine manufacturers to include
      our OPE technology in their product offerings.





Articles
      in appropriate trade journals, prominent newspapers and direct marketing
      campaigns will be used to promote the OPE technology. We will also send out
      special invitations, solicit inquiries and encourage visits our laboratory
      and
      testing facilities for the purpose of demonstrating the engine and its
      technology to potential customers to demonstrate the engine and its unique
      technology, educate the potential buyer/licensee and establish essential
      relationships.





We
      intend
      to expand our marketing efforts to the marine outboard motor industry, as well
      as other small engine applications used in the recreational and other markets,
      such as snowmobiles, small water craft such as Seadoos and all-terrain vehicles.
      We are confident that a high power to weight ratio engine, similar to our
      proposed product design will fit into a large area of applications.





With
      the
      successful test run of the OPE, we have conclusively proven the viability of
      the
      engine concept. Current events and the needs of international markets to
      capitalize on technological advances in propulsion technology immediately have
      necessitated an expansion of our mission. Global supply issues of conventional
      fuels and rapid advances of software and electric control, measurement and
      communication techniques have changed the competitive environment. Thus, we
      are
      concentrating on licensing the OPE technology to all available markets.
      Concurrently we are inviting new technologies that may be used in conjunction
      with the OPE in order to be able to eventually offer complete propulsion and/or
      power generating systems to the market.

***Joint
      Venture Agreements***





On
      27
      January 2006, we entered into a letter of intent with Apollo Energy Systems,
      Inc. for the purpose of developing hybrid electric car technology. All
      administrative and legal costs would be shared, and an operational cost sharing
      pan will be based on partner contribution. No significant activities occurred
      in
      the joint venture during the period ended 30 April 2007.





On
      18
      July 2006, we entered into an Engine Development and License Agreement (the
      “License Agreement”) with an unrelated party, Obvio ! Automotoveiculos S.A.
      (“Obvio !”), located in Brazil. Pursuant to the terms of the License Agreement
      the parties have agreed to enter into a non-exclusive joint venture to develop
      a
      third generation OPE suitable for hybrid applications. Under the terms of the
      License Agreement, we will grant Obvio ! with a license for OPE technology
      in
      consideration of $5,000,000, which will be payable in increments of $500 for
      each engine installed or sold. Upon receipt of $5,000,000 from Obvio !, the
      Company will receive royalties of $100 per vehicle sold that incorporates OPE
      technology. According to the terms of the License Agreement we have committed
      to:





i)
            keep
                the OPE patents in good standing and ensure that maintenance fees
                are paid
                in a timely manner; and





ii)
            exercise
                the Option for all patents on or before 31 May 2007 or negotiate
                an
                extension.





No
      significant activities occurred in the joint venture during the period ended
      April 30, 2007.





On
      28
      August 2006, we entered into a letter of intent with Autocraft Industries,
      Inc.
      for the purpose of developing energy efficient propulsion systems for on and
      off
      road vehicles. No significant activities occurred in the joint venture during
      the period ended April 30, 2007.





***Government
      and Industry Regulation***





Since
      it
      our intention to develop the engine to a point where the technology can be
      sublicensed to a third party manufacturer for production, we don't anticipate
      being subject to any government or industry regulations in our testing and
      development processes. We have not yet been required to obtain any licenses
      and/or permits and are not aware of any health or environmental rules and/or
      regulations that apply to our development activities. However, new laws, rules
      and/or regulations may be implemented in the future that we are currently
      unaware of and we may be required to comply with such laws, rules and/or
      regulations. Difficulties in obtaining or failure to obtain required licenses
      and approvals could result in delays in the development of our final prototypes
      in each phase.





***Employees
      and Employment Agreements***





At
      present, we have 3 full time employees, which include all of our officers and
      directors, who work on a full time or as-needed basis. We presently do not
      have
      pension, health, annuity, insurance, profit sharing or similar benefit plans;
      however, we may adopt such plans in the future. There are presently no personal
      benefits available to any officers, directors or key employees. However, the
      Company has issued stock and share purchase warrants to directors and officers
      for their services. Please refer to the tables in Item 10 of this
      report **.**

***Item
        1A. Risk Factors***
  Our
        securities are highly speculative and involve a high degree of risk, including
        among other items the risk factors described below. You should carefully
        consider the following risk factors and other information in this 10-KSB
        before
        deciding to invest in us.


*RISKS
      RELATED TO OUR BUSINESS:*




***Due
      to Our History of Operating Losses, We are Uncertain That We Will Be Able to
      Maintain Sufficient Cash to Accomplish Our Business
      Objectives***




The
      consolidated financial statements included herein have been prepared assuming
      that we will continue as a going concern. During the fiscal years ended April
      30, 2007 and 2006, we suffered net losses of $863,582 and $2,767,259,
      respectively. At April 30, 2007 and 2006, our stockholders' equity was $205,266
      and $338,077, respectively. There is no assurance that we can successfully
      complete our prototype OPE engine or that we will ever generate revenues.




See
      "Plan
      of Operation" for a description of management's plans in regard to this issue.
      The consolidated financial statements do not include any adjustments relating
      to
      the recoverability and classification of assets or the amounts and
      classification of liabilities that might be necessary should we be unsuccessful
      in implementing these plans.





***We
      do not have any additional source of funding for our business plans and may
      be
      unable to find any such funding if and when needed.***





We
      currently have only $1,482 in cash in the bank and no other source of capital
      has been identified or sought. We are currently seeking alternative sources
      of
      funding, including bank loans, exercise of outstanding warrants, additional
      sales of our equity securities and/or a joint venture partner. If we do find
      an
      alternative source of capital, the terms and conditions of acquiring this
      capital may result in dilution and the resultant lessening of value of the
      shares of common stock of our stockholders.





If
      we are
      not successful in raising sufficient capital through this offering, we will
      be
      faced with several options:





1.
      abandon our business plans, cease operations and go out of
      business;


2.
      continue to seek alternative and acceptable sources of capital;


3.
      bring
      in additional capital that may result in a change of control; or


4.
      identify a joint venture candidate with financing sources.





In
      the
      event of any of the above circumstances you could lose a substantial part or
      all
      of any investment you make in our Company. Our failure to raise sufficient
      capital or find additional funding could have a material adverse effect on
      our
      business, financial condition and operating results, including a possible total
      loss of any investment you may make.





***The
      small engine industry is highly competitive and our technology may not be well
      received or successful.***





The
      small
      engine industry is highly competitive with respect to technology, performance,
      quality and availability of service/parts. There are numerous well-established
      competitors, including national, regional and local small engine manufacturers
      and distributors who have substantially greater financial, marketing, personnel
      and other resources than our company. There can be no assurance that we will
      be
      able to respond to various competitive factors affecting our industry and
      technology. The need for small engine equipment is also generally affected
      by
      changes in consumer preferences, national, regional and local economic and
      environmental regulations and demographic trends. Prior to our acquisition
      of
      the engine and technology, it experienced a critical mechanical failure and
      was
      disassembled to investigate the cause of the problem. Failure analyses showed
      metal fatigue to be the cause of the critical component having failed. It was
      subsequently determined that choice of materials specified in the original
      design was ultimately the cause of the failure. A replacement component was
      re-specified and fabricated from a more suitable material. There can be no
      assurance that we will be able to successfully develop our proposed technology
      sufficient to create our planned model or, that if developed, it will suitably
      pass future testing and not fail again. If we are unable to successfully compete
      in the development and marketing of our finished product, we may be unable
      to
      generate any revenues and you could suffer a total loss of any investment you
      make in our securities.





***We
      may be unable to protect the proprietary rights to the technologies, patents
      and
      intellectual property, which may hamper our ability to license and/or sell
      the
      manufacturing rights to the technology, thereby impacting our ability to earn
      revenues and become profitable.***





Our
      success and ability to compete will depend in part on the protection of the
      patents to the technology. We rely on patent and copyright laws to protect
      the
      intellectual property that was developed and have an option to acquire several
      patents on the technology. However, such laws may provide insufficient
      protection. Moreover, other companies may develop products that are similar
      or
      superior to our prototype engine, or may copy or otherwise obtain and use
      proprietary information we develop or use without our authorization. If a third
      party were to violate one or more of the patents or the new technology we
      develop, we may not have the resources to bring suit or protect the intellectual
      property underlying the patents. In the event of such a violation or if a third
      party appropriated any of our unpatented technology, such party may develop
      and
      market technology and/or products which we intend to develop and/or market.
      We
      would lose any revenues, which we would otherwise have received from the sale
      or
      licensing of that technology or those products. This could prevent our ever
      making a profit on any licensing and/or sale of any technology or products
      we
      develop.





We
      do not
      currently own the intellectual property underlying the engine's technology,
      but
      rather, have an option to us the technology for and additional 37 months, at
      which time we will have to purchase it outright for $1,500,000. Our business
      plans are to develop the technology and build a prototype engine that can be
      sublicensed to third party manufacturers for amounts sufficient to generate
      the
      funds to purchase the patent rights subject of the option agreement; however,
      if
      we are unable to do so prior to the expiration date of the option, we would
      need
      to raise additional capital through loans or equity sales, or rely on receipt
      of
      the cash we would receive from exercise of the warrants sold in this offering
      to
      exercise the option. We cannot guarantee that we will ever develop a successful
      prototype or that, if successfully developed, we will be able to sublicense
      the
      rights to any manufacturer for production and sale. As a result, we may never
      have the funds to purchase the patents, which would result in a total failure
      of
      our business and a complete loss of any investment you make in our securities.





Policing
      unauthorized use of the patents, proprietary and other intellectual property
      rights could entail significant expense and could be difficult or impossible.
      In
      addition, third parties may bring claims of copyright or trademark infringement
      against us or claim that certain of our processes or features violate a patent,
      that we have misappropriated their technology or formats or otherwise infringed
      upon their proprietary rights. Any claims of infringement, with or without
      merit, could be time consuming to defend, result in costly litigation, divert
      management attention and/or require us to enter into costly royalty and/or
      licensing arrangements to prevent further infringement on the technology we
      develop or use, any of which could increase our operating expenses and thus
      prevent us from becoming profitable.





8




Our
      competitive position also depends upon unpatented trade secrets. Trade secrets
      are difficult to protect. Our competitors may independently develop proprietary
      information and techniques that are substantially equivalent to the technology
      we use, or otherwise gain access to trade secrets we develop surrounding the
      engine development, such as through unauthorized or inadvertent disclosure
      of
      our trade secrets. If this occurs, our competitors may use our processes or
      techniques to develop competing products and bring them to market ahead of
      us.
      This could prevent us from becoming profitable. As a result of any of the
      aforementioned circumstances, you could suffer a total loss of any investment
      you make in our securities.





***We
      may not be able to successfully develop a marketable
      product.***





Since
      we
      are in the early stages of our engine development process, we cannot guarantee
      that we will be able to successfully complete an engine that meets the
      specifications we have set forth and are attempting to develop. Our final
      product may not function as we believe it will; its projected potential
      applications may be limited; and it may never be a viable product. If we are
      unable to successfully develop the engine technology as planned and it is not
      functional or commercially attractive to third parties, we may never be able
      to
      license the technology or sell the rights to manufacture our products. In such
      event, we would be able to generate any revenues and any investment you made
      in
      our securities would be a total loss.





***The
      loss of our current management would make it very difficult for us to continue
      our proposed business plans.***




Investors
      must rely upon the ability, expertise, judgment, discretion, integrity and
      good
      faith of our management and directors. Our success is highly dependent on our
      current management, key personnel and key consultants. The unexpected loss
      or
      departure of any of these parties could be detrimental to our future success.
      We
      do not maintain key man insurance on our management.




*RISKS
      RELATING TO OUR COMMON STOCK:*





***We
      have numerous outstanding Warrants which may adversely affect the price of
      our
      common stock.***




We
      have
      reserved 11,962,160 shares of our Common Stock for issuance upon exercise of
      outstanding warrants at prices between $0.15 and $0.50 per share.  Any sale
      into the public market of our Common Stock purchased privately at prices below
      the current market price could be expected to have a depressive effect on the
      market price of our Common Stock. See "Market for the Registrant's Common Stock
      and Related Stockholder Matters - Market Information."




***Future
      sales of our common stock may cause our stock price to
      decline.***




Our
      stock
      price may decline by future sales of our shares or the perception that such
      sales may occur. If we issue additional shares of Common Stock in private
      financings under an exemption from the registration laws, then those shares
      will
      constitute "restricted shares" as defined in Rule 144 under the Securities
      Act
      of 1933 (the "Act"). The restricted shares may only be sold if they are
      registered under the Act, or sold under Rule 144, or another exemption from
      registration under the Act.




Some
      of
      our outstanding restricted shares of Common Stock are either eligible for sale
      pursuant to Rule 144 or have been registered under the Act for resale by the
      holders. We are unable to estimate the amount, timing, or nature of future
      sales
      of outstanding Common Stock. Sales of substantial amounts of our Common Stock
      in
      the public market may cause the stock's market price to decline. See "Market
      for
      the Registrant's Common Stock and Related Stockholder Matters - Market
      Information."




***We
      do not expect to pay dividends.***




We
      have
      not paid dividends since inception on our Common Stock, and we do not
      contemplate paying dividends in the foreseeable future on our Common Stock
      in
      order to use all of our earnings, if any, to finance expansion of our business
      plans.




***Lack
      of trading market may make it difficult to sell our common
      stock.***




The
      only
      trading in our Common Stock is conducted on the Over-the Counter ("OTC")
      Bulletin Board. As a result, an investor may find it more difficult to dispose
      of, or to obtain accurate quotations as to the market value of, the Common
      Stock. In addition, our Common Stock is defined as a "penny stock" by rules
      adopted by the U.S. Securities and Exchange Commission. In such event, brokers
      and dealers effecting transactions in the Common Stock with or for the account
      of a customer must obtain the written consent of a customer prior to purchasing
      the Common Stock, must obtain certain information from the customer and must
      provide certain disclosures to such customer. These requirements may have the
      effect of reducing the level of trading in the secondary market, if any, of
      the
      Common Stock and reducing the liquidity of the Common Stock.





***Our
      stock price can be extremely volatile.***




Our
      Common Stock is traded on the OTC Bulletin Board. As a result, an investor
      may
      find it more difficult to dispose of, or to obtain accurate quotations as to
      the
      market value of, the Common Stock. There can be no assurance that an active
      public market will continue for the Common Stock, or that the market price
      for
      the Common Stock will not decline below its current price. Such price may be
      influenced by many factors, including, but not limited to, investor perception
      of us and our industry and general economic and market conditions. The trading
      price of the Common Stock could be subject to wide fluctuations in response
      to
      announcements of our business developments or those of our competitors,
      quarterly variations in operating results, and other events or factors. In
      addition, stock markets have experienced extreme price volatility in recent
      years. This volatility has had a substantial effect on the market prices of
      companies, at times for reasons unrelated to their operating performance. Such
      broad market fluctuations may adversely affect the price of our Common
      Stock.

We
      do not
      currently own any property. We currently are using office space located at
      300 B
      Street in Santa Rosa, California. The space consists of approximately 1,000sq
      ft. We currently have a lease agreement with Schellinger Brothers, an unrelated
      third party, for corporate office space. The lease term is renewable annually.
      We believe that this arrangement is suitable given the nature of our current

The
      closing price of the Common Stock as reported by the OTCBB on July 21, 2006,
      was
      $0.0261 per share.




***Holders***




As
      of
      July 21, 2007, there were 115 holders of Common Stock, who collectively held
      30,440,886 issued and outstanding shares of Common Stock.

***Dividends***




We
      did
      not declare or pay cash or other dividends on its Common Stock during the last
      two calendar years. We currently have no plans to pay any dividends, although
      we
      may do so if our financial position changes.




***Equity
      Compensation Plans***




We
      have
      not adopted any equity compensation plans; however, during the year ended April
      30, 2007, we issued a total of 2,500,000 incentive share purchase warrants
      with
      an exercise price of $0.15 per share to our directors, officers, consultants
      and
      employees. The warrants are intended to provide incentives to officers,
      employees, consultants and advisers (including members of the Board of
      Directors), who contribute to the success of the Company by offering them the
      opportunity to acquire an ownership interest in it. The Board of Directors
      believes that this also will help to align the interests of our management
      and
      employees with the interests of our stockholders.




The
      number of shares reserved for issuance of Common Stock underlying the warrants
      is the maximum aggregate amount, assuming exercise of all warrants, which were
      registered by the filing of a Form S-8 registration statement with the SEC;
      a
      complete copy of the S-8 can be found on the SEC website at www.sec.gov under
      our SEC File Number 333-116324 .





In
      the
      event a change, such as a stock split, is made in our capitalization which
      results in an exchange or other adjustment of each share of Common Stock for
      or
      into a greater or lesser number of shares, appropriate adjustments will be
      made
      to outstanding, unexercised warrants and in the exercise price and in the number
      of shares subject to each outstanding warrant. The Committee also may make
      provisions for adjusting the number of bonuses or underlying outstanding
      warrants in the event we effect one or more reorganizations, recapitalizations,
      rights offerings, or other increases or reductions of shares of our outstanding
      Common Stock.





***Share
      Purchase Warrants***





During
      the year ended April 30, 2007, we extended the expiration date on a total of
      3,500,000 outstanding warrants to August 2009.





The
      following share purchase warrants were outstanding at 30 April
      2007:

      Black-Scholes option pricing model and the following weighted average
      assumptions:

***Results
        of Operations***
 
 For
        the
        year ended April 30, 2007, we incurred a net operating loss of $863,582,
        as
        compared to a net loss of $2,767,259 for the year ended April 30,
        2006.
 
 We
        incurred total expenses of $878,582 for the year ended April 30, 2007, as
        compared to total expenses of $2,580,185 for the year ended April 30, 2006.
        The
        majority of the expense was $414,711, the estimated fair value of incentive
        share purchase warrants issued to directors, officers and employees during
        the
        period. A total of $114,935 in consulting fees was paid, none to related
        parties. A total of $45,358 was paid for investor relations during the period
        and $96,679 in public relations and preparation and dissemination of shareholder
        information. A total of $64,562 was paid in professional fees for the year
        ended
        April 30, 2007, which generally consisted of fees for legal, accounting and
        outside services paid in connection with the preparation and filing of our
        periodic reports. Research and development expense was $418 for the year
        ended
        April 30, 2007. A total of $100,000 was expensed as the fair market value
        of
        management fees for services contributed by our officers and directors during
        the year ended April 30, 2007. The balance of general and administrative
        expenses were attributed to miscellaneous office expenses, filing fees, rent,
        travel and entertainment and day-to-day operating expenses.
 
 During
        the year ended April 30, 2007, we recovered $15,000 from a related company
        with
        two directors in common. This amount relates to the $177,204 previously written
        off during the year ended April 30, 2006 that we had deemed to be uncollectible.

***Liquidity
      and Capital Resources***





We
      currently have only $1,482 in cash on hand and are seeking sources of funding
      to
      continue our operations. It is expected we will continue to need further funding
      until we complete a final prototype to bring to market for sale or enter into
      an
      agreement with a joint venture partner to complete our plans. We are currently
      researching both options; however, no definitive agreements have yet been
      entered into. We currently plan to fund future operations by public offerings
      or
      private placement of equity and/or debt securities as we have done in the past.
      However, there can be no assurance that debt or equity financing will be
      available to us on acceptable terms to meet these requirements, as and when
      needed. Our auditors have expressed substantial
      doubt about our ability to continue as a going concern





As
      of the
      date of this annual report, we have not yet generated any revenues.





We
      do not
      intend to purchase any significant property or equipment, nor incur any
      significant changes in employees during the next 12 months.





Cash
      provided by financing activities for the year ended April 30, 2007 was $34,000,
      attributed to $24,000 in private sales of our common stock, $10,000 received
      from a promissory note payable.





There
      was
      no cash used in investing activities for the year ended April 30,
      2007.





Our

**Item
      8. Changes in and Disagreements with Accountants on Accounting and Financial
      Disclosures**





There
      have been no disagreements with our accountants on accounting or other financial
      disclosures since inception.





On
      November 9, 2006, our independent auditors, Staley, Okada & Partners,
      Chartered Accountants, informed us by letter that they had sold their business
      to PricewaterhouseCoopers LLP and were resigning as our independent auditors.





Since
      the
      appointment of Staley, Okada & Partners, Chartered Accountants on May 31,
      2005, and all subsequent interim periods through the date of their resignation
      on November 9, 2006, Staley, Okada & Partners, Chartered Accountants’
reports on our financial statements did not contain an adverse opinion or
      disclaimer of opinion, nor were they modified as to audit scope or accounting
      principles. The audit report for the fiscal years ended April 30, 2005 and
      2006
      were modified as to the uncertainty regarding our ability to continue as a
      going
      concern because of out status as a development stage company with limited
      operations. The audited financial statements for the fiscal years ended April
      30, 2006 and April 30, 2005 did not include any adjustments that might have
      resulted from the outcome of this uncertainty. From the date of the appointment
      on May 31, 2005 through the firm’s resignation, there were no disagreements with
      Staley, Okada & Partners, Chartered Accountants on any matter of accounting
      principles or practices, financial statement disclosure, or auditing scope
      or
      procedure which, if not resolved to Staley, Okada & Partners, Chartered
      Accountants' satisfaction, would have caused Staley, Okada & Partners,
      Chartered Accountants to make reference to the subject matter in connection
      with
      its reports and/or reviews of our consolidated financial statements during
      our
      most recent fiscal years, or any interim period.

**Item
      8a. Controls and Procedures**





***Critical
      Accounting Policies***





The
      financial statements included herein have been prepared pursuant to the rules
      and regulations of the Securities and Exchange Commission. Management believes
      the disclosures made are adequate to make the information not misleading. The
      financial statements and accompanying notes are prepared in accordance with
      the
      United States generally accepted accounting principles. Preparing financial
      statements requires Management to make estimates and assumptions that affect
      the
      reported amounts of assets and liabilities and disclosure of contingent assets
      and liabilities at the date of the financial statements and the reported amounts
      of revenues and expenses during the reporting period. These estimates and
      assumptions are affected by Management's application of accounting policies.
      These important accounting policies include the successful efforts method of
      accounting for property and equipment, revenue recognition, accounting for
      income taxes and foreign currency translation.





Management
      maintains disclosure controls and procedures designed to ensure that we are
      able
      to timely collect the information we are required to disclose in our reports
      filed with the U.S. Securities and Exchange Commission.





As
      of the
      end of the period covered by this report, we performed an evaluation, under
      the
      supervision and with the participation of our Management, of the effectiveness
      of the design and operation of our disclosure controls and procedures pursuant
      to Exchange Act Rule 13a-14. Based upon the evaluation, our Principal Executive
      Officer and Principal Accounting Officer concluded that the current disclosure
      controls are effective in timely alerting us to any material information
      required to be included in our periodic SEC filings.





We
      also
      maintain a system of internal controls designed to provide reasonable assurance
      that (i) transactions are executed in accordance with Management's general
      and
      specific authorization; (ii) transactions are recorded as necessary to permit
      preparation of financial statements in conformity with the United States
      generally accepted accounting principles and to maintain accountability for
      assets; (ii) access to assets is permitted only in accordance with Management's
      general or specific authorization; and (iv) the recorded accountability for
      assets is compared with the existing assets at reasonable intervals and
      appropriate action is taken with respect to any differences. We believe that
      our
      internal controls are effective to provide reasonable assurance that our
      financial statements are fairly presented in conformity with generally accepted
      accounting principals. Since our most recent evaluation, there have been no
      changes in our internal controls or in other factors that could significantly
      affect our internal controls, nor were any corrective actions required with
      regard to significant deficiencies and material weaknesses.





However,
      our auditors did not test the effectiveness of nor relied on our internal
      controls for the fiscal year ended April 30, 2007.

The

***Section
      16(a) Beneficial Ownership Reporting Compliance***





Section
      16(a) of the Securities Exchange Act of 1934 requires our directors and
      executive officers, and persons who own more than ten percent of our Common
      Stock, to file with the Securities and Exchange Commission initial reports
      of
      ownership and reports of changes of ownership of our Common Stock. Officers,
      directors and greater than ten percent stockholders are required by SEC
      regulation to furnish us with
      copies of all Section 16(a) forms they file. To the best of our knowledge,
      all
      Section 16(a) filing requirements applicable to our officers, directors and
      greater than ten percent beneficial owners were complied with. In making these
      disclosures, we have relied solely on a review of the copies of such reports
      furnished to us and written representations by our directors, executive officers
      and greater than ten percent stockholders.




***Code
      of Ethics***





At
      this
      time, we have not adopted a formal Code of Ethics that applies to the Chief
      Financial Officer. We have, however, followed an informal Code of Ethics
      requiring Board of Director approval of any material transaction involving
      our
      Chief Financial Officer. We believe this procedure reasonably deters material
      wrongdoing and promotes honest and ethical conduct from our executive
      officers.

      stockholder of the Company. This balance is non-interest bearing, unsecured
      and
      has no fixed terms of repayment.

      with
      two directors in common. This amount relates to the $177,204, previously written

      uncollectible from related company.




During
      the year ended April 30, 2007, we issued 2,500,000 share purchase warrants
      to
      our officers and directors; each share purchase warrant entitles the holder
      to
      purchase an additional common share at a price of $0.15 until December
      2011.





During
      the year ended April 30, 2007, officers and directors made contributions to
      capital for management fees in the amount of $100,000. These amounts have been
      recorded as an increase in expenditures and an increase in additional paid-in
      capital.

      the year ended April 30, 2007, the Company recognized stock compensation expense
      of $78,061 on the amendment of the expiry date of 2,000,000 warrants issued

      accountant for the audit of our annual financial statements for the fiscal
      year
      ended April 30, 2007 were $8,716 and $12,500 for the fiscal year ended April
      30,
      2006. The reviews for the financial statements included in our quarterly reports
      on Form 10-QSB during the fiscal year ended April 30, 2007 were
      $5,738.





***Audit
      Related Fees***





We
      incurred no fees for the fiscal years ended April 30, 2007 and 2006 for
      assurance and related services by our principal accountant that were reasonably
      related to the performance of the audit or review of our financial statements,
      and not reported under Audit Fees above.


21





***Tax
      Fees***





The
      aggregate fees billed for professional services rendered by our principal
      accountant for tax compliance, tax advice, preparation and filing of tax returns
      and tax planning for the fiscal years ended April 30, 2007 and 2006 were nil.





***All
      Other Fees***





We
      incurred no other fees during the fiscal years ended April 30, 2007 and 2006
      for
      products and services rendered by our principal accountants.





***Audit
      Committee Requirements***




Section 10A(i) of
      the Exchange Act prohibits our auditors from performing audit services for
      us,
      as well as any services not considered to be "audit services", unless such
      services are pre-approved by the audit committee of the Board of Directors,
      or
      unless the services meet certain *de
      minimis* standards. Because we are still in the development stage and have not yet
      completed our business plans and/or generated any revenues, we have not yet
      appointed an audit committee. Our Board of Directors ensure that:




·
            All
                audit services that the auditor may provide to us or any subsidiary
                (including, without limitation, providing comfort letters in connection
                with securities underwritings or statutory audits) as required by
                §10A(i)(1)(A) of the Exchange Act (as amended by the Sarbanes-Oxley
                Act of
                2002) are preapproved by the Board.




·
            All
                non-audit services (other than certain*de
                minimis*services described in §10A(i)(1)(B) of the Exchange Act (as amended by the
                Sarbanes-Oxley Act of 2002)) that the auditors propose to provide
                to us or
                any of our subsidiaries are preapproved by the Board.




All
      audit
      fees were approved by the Board of Directors.

      at 30
      April 2007 and the related consolidated statements of operations, cash flows
      and
      changes in stockholders’ equity for the year then ended. We have also audited
      the statements of operations, cash flows and changes in stockholders’ equity for
      the period from the date of inception on 2 September 2003 through 30 April
      2007,
      except that we did not audit these financial statements for the period from
      the
      date of inception on 2 September 2003 through 30 April 2006; those statements
      were audited by other auditors whose report dated 7 July 2006 expressed an
      unqualified opinion on those statements. These financial statements are the
      responsibility of the Company’s management. Our responsibility is to express an
      opinion on these financial statements based on our audit.




We
      conducted our audit in accordance with the standards of the Public Company
      Accounting Oversight Board (United States of America). Those standards require
      that we plan and perform the audit to obtain reasonable assurance about whether
      the financial statements are free of material misstatement. An audit includes
      examining, on a test basis, evidence supporting the amounts and disclosures
      in
      the financial statements. An audit also includes assessing the accounting
      principles used and significant estimates made by management, as well as
      evaluating the overall financial statement presentation. We believe that our
      audit provides a reasonable basis for our opinion.




In
      our
      opinion, the financial statements referred to above present fairly, in all
      material respects, the financial position of the Company as of 30 April 2007
      and
      the results of its operations, its cash flows and its changes in stockholders’
equity for the year then ended and for the period from the date of inception
      on
      2 September 2003 to 30 April 2007 in conformity with accounting principles
      generally accepted in the United States of America.





The
      accompanying financial statements have been prepared assuming that the Company
      will continue as a going concern. As discussed in Note 1 to the financial
      statements, conditions exist which raise substantial doubt about the Company’s
      ability to continue as a going concern unless it is able to generate sufficient
      cash flows to meet its obligations and sustain its operations. Management’s
      plans in regard to these matters are also described in Note 1. The financial
      statements do not include any adjustments that might result from the outcome
      of
      this uncertainty.

**1.**
            **Nature
                and Continuance of
                Operations**





Rotoblock
      Corporation (the “Company”) was incorporated under the laws of the State of
      Nevada on 22 March 2004.





The
      Company is a development stage enterprise, as defined in Statements
      of Financial Accounting Standards (“SFAS”)
      No. 7, “ *Accounting
      and Reporting by Development Stage Enterprises* ”.
      The
      Company is devoting all of its present efforts to develop and market a new
      type
      of patented oscillating piston engine. No revenue has been derived during the
      organization period and our planned principle operations have not commenced.





The
      Company’s financial statements as at 30 April 2007 and for the years then ended
      have been prepared on a going concern basis, which contemplates the realization
      of assets and the settlement of liabilities and commitments in the normal course
      of business. The Company has a loss of $863,582 for the year ended 30 April
      2007
      (30 April 2006 - $2,767,259) and has working capital of $96,521 at 30 April
      2007
      (30 April 2006 - $229,332).





On
      30
      March 2004, the Company entered into a Share Exchange Agreement (the
“Agreement”) with Rotoblock Inc., a Canadian corporation, wherein the Company
      agreed to issue to the stockholders of Rotoblock Inc. 15,000,000 common shares
      in exchange for the 7,200,000 shares that constituted all the issued and
      outstanding shares of Rotoblock Inc. Effective 30 March 2004, Rotoblock Inc.
      completed the reverse acquisition under the Agreement with the Company.





Immediately
      after the acquisition, the management of Rotoblock Inc. took control of the
      board and office positions of the Company, constituting a change of control.
      Because the former owners of Rotoblock Inc. gained control of the Company,
      the
      transaction would normally have been considered a purchase by Rotoblock Inc.
      However, since the Company was not a business, the transaction was not
      considered to be a business combination, and the transaction was accounted
      for
      as a recapitalization of Rotoblock Inc. and the issuance of stock by Rotoblock
      Inc. for the assets and liabilities of the Company. The value of the net assets
      of the Company acquired by Rotoblock Inc. was the same as their historical
      book
      value, being a deficiency of $138.





Rotoblock
      Inc. was incorporated on 2 September 2003, under the laws of Canada. The
      accompanying financial statements are the historical financial statements of
      Rotoblock Inc.





Management
      cannot provide assurance that the Company will ultimately achieve profitable
      operations or become cash flow positive, or raise additional debt and/or equity
      capital. However, based on its prior demonstrated ability to raise capital,
      management believes that the Company’s capital resources should be adequate to
      continue operating and maintaining its business strategy during the fiscal
      year
      ending 30 April 2008. However, if the Company is unable to raise additional
      capital in the near future, due to the Company’s liquidity problems, management
      expects that the Company will need to curtail operations, liquidate assets,
      seek
      additional capital on less favorable terms and/or pursue other remedial
      measures. These financial statements do not include any adjustments related
      to
      the recoverability and classification of assets or the amounts and
      classification of liabilities that might be necessary should the Company be
      unable to continue as a going concern.

**30
      April 2007**





At
      30
      April 2007, the Company has suffered losses from development stage activities
      to
      date. Although management is currently attempting to implement its business
      plan, and is seeking additional sources of equity or debt financing, there
      is no
      assurance these activities will be successful. Accordingly, the Company must
      rely on its management to perform essential functions without compensation
      until
      a business operation can be commenced. These factors raise substantial doubt
      about the ability of the Company to continue as a going concern. The financial
      statements do not include any adjustments that might result from the outcome
      of
      this uncertainty.





**2.**
            **Significant
                Accounting Policies**





The
      following is a summary of significant accounting policies used in the
      preparation of these financial statements.





**Basis
      of presentation**




The
        consolidated financial statements of the Company have been prepared in
        accordance with accounting principles generally accepted in the United States
        of
        America and are expressed in U.S. dollars.


**Basis
      of consolidation**





These
      consolidated financial statements include the accounts of the Company from
      the
      date of reverse acquisition on 30 March 2004, and its wholly owned Canadian
      subsidiary, Rotoblock Inc. since its date of incorporation on 2 September 2003.
      All inter-company balances and transactions have been eliminated on
      consolidation (Note 1).





**Fiscal
      period**





The
      Company’s fiscal year ends on 30 April.





**Risks
      and uncertainties**





The
      Company operates in an emerging industry that is subject to market acceptance
      and technological change. The Company’s operations are subject to significant
      risks and uncertainties, including financial, operational, technological and
      other risks associated with operating an emerging business, including the
      potential risk of business failure.





**Cash
      and cash equivalents**





Cash
      and
      cash equivalents include highly liquid investments with original maturities
      of
      three months or less.

____________________________________________________________________________________________________________________________________________________________________________





**Financial
      instruments**





The
      Company’s financial instruments consist of cash, amounts receivable, accounts
      payable and amounts due to related parties. Unless otherwise noted, it is
      management’s opinion that this Company is not exposed to significant interest or
      credit risks arising from these financial instruments. The fair value of these
      financial instruments approximate their carrying values, unless otherwise
      noted.





**Concentrations
      and credit risk**





The
      Company’s financial instruments that are exposed to concentrations of credit
      risk primarily consist of its cash, accounts payable, interest payable, and
      amounts due to related party. The Company places its cash with financial
      institutions of high credit worthiness. At times, its cash with a particular
      financial institution may exceed any applicable government insurance limits.
      The
      Company’s existence and survival presently depends on its acquisition of certain
      patents (Note 3).





**Derivative
      financial instruments**





The
      Company has not, to the date of these financial statements, entered into
      derivative instruments to offset the impact of foreign currency fluctuations.





**Income
      taxes**





Deferred
      income taxes are reported for timing differences between items of income or
      expense reported in the financial statements and those reported for income
      tax
      purposes in accordance with SFAS No. 109, “ *Accounting
      for Income Taxes* ”,
      which
      requires the use of the asset/liability method of accounting for income taxes.
      Deferred income taxes and tax benefits are recognized for the future tax
      consequences attributable to differences between the financial statement
      carrying amounts of existing assets and liabilities and their respective tax
      bases, and for tax losses and credit carry-forwards. Deferred tax assets and
      liabilities are measured using enacted tax rates expected to apply to taxable
      income in the years in which those temporary differences are expected to be
      recovered or settled. The Company provides for deferred taxes for the estimated
      future tax effects attributable to temporary differences and carry-forwards
      when
      realization is more likely than not.





**Basic
      and diluted net loss per share**





The
      Company computes net income (loss) per share in accordance with SFAS No. 128,
      “ *Earnings
      per Share* ”.
      SFAS
      No. 128 requires presentation of both basic and diluted earnings per share
      (“EPS”) on the face of the income statement. Basic EPS is computed by dividing
      net income (loss) available to common shareholders (numerator) by the weighted
      average number of shares outstanding (denominator) during the period. Diluted
      EPS gives effect to all dilutive potential common shares outstanding during
      the
      period using the treasury stock method and convertible preferred stock using
      the
      if-converted method. In computing diluted EPS, the average stock price for
      the
      period is used in determining the number of shares assumed to be purchased
      from
      the exercise of stock options or warrants. Diluted EPS excludes all dilutive
      potential shares if their effect is anti-dilutive.

**______________________________________________________________________________**





**Comprehensive
      loss**





SFAS
      No.
      130, “ *Reporting
      Comprehensive Income* ”,
      establishes standards for the reporting and display of comprehensive loss and
      its components in the financial statements.





**Long
      lived assets**





SFAS
      No.
      144 “ *Accounting
      for the Impairment or Disposal of Long-Lived Assets* ”
      requires that long-lived assets be reviewed for impairment whenever events
      or
      changes in circumstances indicate that the carrying amount of an asset may
      not
      be recoverable. It establishes guidelines for determining recoverability based
      on future net cash flows from the use of the asset and for the measurement
      of
      the impairment loss. Impairment loss under SFAS No. 144 is calculated as the
      difference between the carrying amount of the asset and its fair value. Any
      impairment loss is recorded in the current period in which recognition criteria
      are first applied and met. Under the successful efforts method of accounting
      for
      oil and gas operations, the Company must periodically assess it proved
      properties for impairments by comparing the aggregate net book carrying amount
      of all proved properties with their aggregate future net cash flows. The
      statement requires that the impairment review be performed on the lowest level
      of asset groupings for which there are identifiable cash flows.





**Segments
      of an enterprise and related information**





SFAS
      No.
      131, “ *Disclosures
      about Segments of an Enterprise and Related Information* ”,
      supersedes SFAS No. 14, “ *Financial
      Reporting for Segments of a Business Enterprise* ”.
      SFAS
      No. 131 establishes standards for the way that public companies report
      information about operating segments in annual financial statements and requires
      reporting of selected information about operating segments in interim financial
      statements issued to the public. It also establishes standards for disclosures
      regarding products and services, geographic areas and major customers. SFAS
      No.
      131 defines operating segments as components of a company about which separate
      financial information is available that is evaluated regularly by the chief
      operating decision maker in deciding how to allocate resources and in assessing
      performance. The Company has evaluated this SFAS and does not believe it is
      applicable at this time.





**Foreign
      currency translation**





The
      Company’s functional and reporting currency is the U.S. dollar. The financial
      statements of the Company are translated to U.S. dollars in accordance with
      SFAS
      No. 52, “ *Foreign
      Currency Translation* ”.
      Monetary assets and liabilities denominated in foreign currencies are translated
      using the exchange rate prevailing at the balance sheet date. Gains and losses
      arising on translation or settlement of foreign currency denominated
      transactions or balances are included in the determination of income. The
      Company has not, to the date of these financial statements, entered into
      derivative instruments to offset the impact of foreign currency fluctuations.

Unrealized
      exchange gains and losses arising from such translations are deferred until
      realization and are included as a separate component of shareholders’ equity as
      a component of comprehensive income or loss. Upon realization, the amount
      deferred is recognized in income in the period when it is realized.





**Stock-based
      compensation**





Effective
      1 January 2006, the Company adopted the provisions of SFAS No. 123(R),
“ *Share-Based
      Payment* ,”
which
      establishes accounting for equity instruments exchanged for employee services.
      Under the provisions of SFAS No. 123(R), stock-based compensation cost is
      measured at the grant date, based on the calculated fair value of the award,
      and
      is recognized as an expense over the employees’ requisite service period
      (generally the vesting period of the equity grant). Before 1 January 2006,
      the
      Company accounted for stock-based compensation to employees in accordance with
      Accounting Principles Board Opinion No. 25, “ *Accounting
      for Stock Issued to Employees,* ”
and
      complied with the disclosure requirements of SFAS No. 123, “ *Accounting
      for Stock-Based Compensation.* ” 
      The Company adopted SFAS NO. 123(R) using the modified prospective method,
      which
      requires the Company to record compensation expense over the vesting period
      for
      all awards granted after the date of adoption, and for the unvested portion
      of
      previously granted awards that remain outstanding at the date of adoption.
      Accordingly, financial statements for the periods prior to 1 January 2006 have
      not been restated to reflect the fair value method of expensing share-based
      compensation. Adoption of SFAS No. 123(R) does not change the way the
      Company accounts for share-based payments to non-employees, with guidance
      provided by SFAS No. 123 (as originally issued) and Emerging Issues Task Force
      Issue No. 96-18, “ *Accounting
      for Equity Instruments That Are Issued to Other Than Employees for Acquiring,
      or
      in Conjunction with Selling, Goods or Services* .”





**Research
      and development**





Research
      and development costs are expensed as incurred.





**Patents**





The
      Company accounts for patent costs in accordance with SFAS No. 142 -
“ *Goodwill
      and Other Intangible Assets* .”
In
      accordance with that statement, intangible assets with estimatable lives, such
      as a patent, are amortized on a straight-line basis over the estimated useful
      lives and are reviewed for impairment in accordance with SFAS No. 144 -
“ *Accounting
      for the Impairment of Long-Lived Assets* .”
The
      patent costs will be amortized over their estimated useful lives upon exercise
      of the option (Note 3).

**Use
      of estimates**





The
      preparation of financial statements in conformity with accounting principles
      generally accepted in the United States of America requires management to make
      estimates and assumptions that affect the amounts of assets and liabilities
      and
      disclosures of contingent assets and liabilities at the date of the financial
      statements and the reported amounts of revenues and expenditures during the
      reporting period. Actual results could differ from these estimates.





**Recent
      accounting pronouncements**





In
      February 2007, the Financial Accounting Standards Board (the “FASB”) issued SFAS
      No. 159, *“The
      Fair Value Option for Financial Assets and Financial Liabilities”* (SFAS
      159). SFAS 159 allows the company to choose to measure many financial assets
      and
      financial liabilities at fair value. Unrealized gains and losses on items for
      which the fair value option has been elected are reported in earnings. SFAS
      159
      is effective for fiscal years beginning after 15 November 2007. The Company
      is
      currently evaluating the requirements of SFAS 159 and the potential impact
      on
      the Company’s financial statements.





In
      March
      2006, the FASB  issued
      SFAS No. 156, “ *Accounting
      for Servicing of Financial Assets* ”,
      which
      amends SFAS No. 140. SFAS No. 156 may be adopted as early as 1 January 2006,
      for
      calendar year-end entities, provided that no interim financial statements have
      been issued. Those not choosing to early adopt are required to apply the
      provisions as of the beginning of the first fiscal year that begins after 15
      October 2006 (e.g., 1 January 2007, for calendar year-end entities).  The
      intention of the new statement is to simplify accounting for separately
      recognized servicing assets and liabilities, such as those common with mortgage
      securitization activities, as well as to simplify efforts to obtain hedge-like
      accounting.  Specifically, the FASB said SFAS No. 156 permits a servicer
      using derivative financial instruments to report both the derivative financial
      instrument and related servicing asset or liability by using a consistent
      measurement attribute, or fair value.  The adoption of SFAS No. 156 is
      not expected to have a material impact on the Company’s financial position,
      results of operations or cash flows.





In
      February 2006, the FASB issued SFAS No. 155, “ *Accounting
      for Certain Hybrid Financial Instruments* ”,
      which
      amends SFAS No. 133, “ *Accounting
      for Derivative Instruments and Hedging Activities* ”
and
      SFAS No. 140, “ *Accounting
      for Transfers and Servicing of Financial Assets and Extinguishments of
      Liabilities* ”.
      SFAS
      No. 155 permits fair value measurement for any hybrid financial instrument
      that contains an embedded derivative that otherwise would require bifurcation,
      establishes a requirement to evaluate interests in securitized financial assets
      to identify interests that are freestanding derivatives or hybrid financial
      instruments containing embedded derivatives. The adoption of SFAS No. 155
      is not expected to have a material impact on the Company’s financial position,
      results of operations or cash flows.





In
      September 2006, the FASB issued SFAS No.
      158, *“Employers’
      Accounting for Defined Benefit Pension and Other Postretirement Plans - an
      amendment of FASB Statements No. 87, 88, 106 and 132(R)”* (SFAS
      158”). SFAS 158 requires an employer that sponsors one or more single-employer
      defined benefit plans to (a) recognize the overfunded or underfunded status
      of a
      benefit plan in its statement of financial position, (b) recognize as a
      component of other comprehensive income, net of

      gains or losses and prior service costs or credits that arise during the period
      but are not recognized as components of net periodic benefit cost pursuant to SFAS 87,
      “Employers’ Accounting for Pensions”, or SFAS 106, *“Employers’
      Accounting for Postretirement Benefits Other Than Pensions”* ,
      (c)
      measure defined benefit plan assets and obligations as of the date of the
      employer’s fiscal year-end, and (d) disclose in the notes to financial
      statements additional information about certain effects on net periodic benefit
      cost for the next fiscal year that arise from delayed recognition of the gains
      or losses, prior service costs or credits, and transition asset or obligation.
      SFAS 158 is effective for the Company’s fiscal year ending 30 April 2007. The
      Company is currently reviewing the impact of this statement.





In
      September 2006, the FASB issued SFAS No. 157, *"Fair
      Value Measurement"* ("SFAS
      157"). The Statement provides guidance for using fair value to measure assets
      and liabilities. The Statement also expands disclosures about the extent to
      which companies measure assets and liabilities at fair value, the information
      used to measure fair value, and the effect of fair value measurement on
      earnings. This Statement applies under other accounting pronouncements that
      require or permit fair value measurements. This Statement does not expand the
      use of fair value measurements in any new circumstances. Under this Statement,
      fair value refers to the price that would be received to sell an asset or paid
      to transfer a liability in an orderly transaction between market participants
      in
      the market in which the entity transacts. SFAS 157 is effective for the Company
      for fair value measurements and disclosures made by the Company in its fiscal
      year beginning on 1 May 2008. The Company is currently reviewing the impact
      of
      this statement.





In
      May 2005, FASB issued SFAS 154, *“Accounting
      Changes and Error Corrections”* ,
      which
      replaces APB Opinion No. 20, *“Accounting
      Changes,”* and
      supersedes FASB Statement No. 3, *“Reporting
      Accounting Changes in Interim Financial Statements - an amendment of APB Opinion
      No. 28.”* SFAS 154
      requires retrospective application to prior periods’ financial statements of
      changes in accounting principle, unless it is impracticable to determine either
      the period-specific effects or the cumulative effect of the change. When it
      is
      impracticable to determine the period-specific effects of an accounting change
      on one or more individual prior periods presented, SFAS 154 requires that the
      new accounting principle be applied to the balances of assets and liabilities
      as
      of the beginning of the earliest period for which retrospective application
      is
      practicable and that a corresponding adjustment be made to the opening balance
      of retained earnings for that period rather than being reported in an income
      statement. When it is impracticable to determine the cumulative effect of
      applying a change in accounting principle to all prior periods, SFAS 154
      requires that the new accounting principle be applied as if it were adopted
      prospectively from the earliest date practicable. SFAS 154 shall be effective
      for accounting changes and corrections of errors made in fiscal years beginning
      after 15 December 2005. The Company does not expect the provisions of SFAS
      154
      will have a significant impact on its results of operations.

      April 2006 - 3,617,338 common shares). Of these, 1,083,036 common shares (30
      April 2006 - 3,555,279 common shares) were restricted from trading as defined
      under Rule 144 of the United States Securities Act of 1933.

**11.**
            **Income
                Taxes**





The
      Company has losses carried forward for income tax purposes to 30 April 2007.
      There are no current or deferred tax expenses for the period ended 30 April
      2007
      due to the Company’s loss position. The Company has not reserved for any
      benefits of these losses. The deferred tax consequences of temporary differences
      in reporting items for financial statement and income tax purposes are
      recognized, as appropriate. Realization of the future tax benefits related
      to
      the deferred tax assets is dependent on many factors, including the Company’s
      ability to generate taxable income within the net operating loss carry forward
      period. Management has considered these factors in reaching its conclusion
      as to
      the valuation allowance for financial reporting purposes.

      tax purposes of approximately $1,629,727 that are available to offset future
      taxable income. This unused net operating loss carry forward balance for income
      tax purposes expires between the years 2024 and 2027.

**Report
      of Independent Registered Public Accounting Firm**




**To
      the Stockholders of Rotoblock Corporation:**




We
      have
      audited the accompanying consolidated balance sheets of Rotoblock Corporation
      (the “Company”) as at April 30, 2006 and 2005 and the related consolidated
      statements changes in stockholders’ equity, operations, and cash flows for each
      of the years ended April 30, 2006 and 2005. These financial statements are
      the
      responsibility of the Company's management. Our responsibility is to express
      an
      opinion on these financial statements based on our audits.




We
      conducted our audits in accordance with the standards of the Public Company
      Accounting Oversight Board (United States). Those standards require that we
      plan
      and perform the audits to obtain reasonable assurance about whether the
      financial statements are free of material misstatement. The Company is not
      required to have, nor were we engaged to perform an audit of its internal
      control over financial reporting. Our audits included consideration of internal
      control over financial reporting as a basis for designing audit procedures
      that
      are appropriate in the circumstances, but not for the purpose of expressing
      an
      opinion on the effectiveness of the Company’s internal control over financial
      reporting. Accordingly, we express no such opinion. An audit also includes
      examining, on a test basis, evidence supporting the amounts and disclosures
      in
      the financial statements, assessing the accounting principles used and
      significant estimates made by management, as well as evaluating the overall
      financial statement presentation. We believe that our audits provide a
      reasonable basis for our opinion.




In
      our
      opinion, the consolidated financial statements referred to above present fairly,
      in all material respects, the financial position of the Company as at April
      30,
      2006 and 2005, and the results of its operations and its cash flows for each
      of
      the years ended April 30, 2006 and 2005, in conformity with United States
      generally accepted accounting principles.





The
      accompanying consolidated financial statements have been prepared assuming
      that
      the Company will continue as a going concern. As discussed in Note 1 to the
      financial statements, the Company is dependent upon financing to continue
      operations and had suffered recurring losses from operations. These matters
      raise substantial doubt about the Company's ability to continue as a going
      concern. Management's plans in regards to these matters are discussed in Note
      1.
      The financial statements do not include any adjustments that might result from
      the outcome of this uncertainty.




The
      April
      30, 2004 figures, which are presented for comparative purposes, were audited
      by
      another firm of Chartered Accountants, who expressed an unqualified auditors’
report dated May 14, 2004.
