Abstract:
A useful system for our transportation needs must be in concert with the ecological and economical needs of the future. 
     The vehicle concept considers all the constrains imposed by battery materials, oil and electric energy availability and production capacity, electric grid power capability and will make transportation cheaper faster and more robust than the current system. 
     The multi-feature vehicle is modular in design separating and placing optimally the functional modules so that many variations are easily possible allowing the range, carrying capacity and multi-modal transportation to be optimized. The multi modal transportation feature is a surrogate for the lack of battery capacity to cover the individual needs for transportation avoiding the need for large capital cost for large batteries and their maintenance. The vehicle may serve as backup power source during blackouts and uses own modular compactable solar energy harvesting devices. 
     The intent of this proposal is to demonstrate the viability of this multi-modal concept and develop the necessary hardware and software to become market ready.

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of no U.S. Provisional Application 61/211,556 incorporated by reference in this entity. 
     
    
     BACKGROUND 
       [0002]    No matter the price fluctuations; declarations of the oil producers, the time of gas-fueled vehicles is going to end. In less than 30 years gasoline will become a very scarce resource. The actual electric cars, following the actual cars concepts requires a lot of batteries, becoming heavy and expensive. 
         [0003]    The electric vehicle becomes a strong candidate to replace the thermal engine powered vehicles, but statistic data shows a big shortage ahead in battery materials, available electric power and grid robustness, affordability of the real cost, the daily range: 
         [0004]    The Battery Materials: 
         [0005]    The World Lithium production is of 21.4 kt/y, while the world&#39;s reserves are of about 6.2 Mt. The Ni production is of 134 kt/y, and lead is of the 3.77 Mt/y. 
         [0006]    A Advanced Electric Vehicle has 53 kWh, for about 200 miles autonomy transporting a weight of 1¼ tons. The 53 kWh batteries weight 450 kg and may take more than 0.1 t of Lithium to be produced. Similar capacity batteries may use about 0.15 t of Ni, or 0.4 t of Lead. 
         [0007]    If the world production will be entirely diverted for electric cars it will be possible to produce 214 k vehicles with Li-Ion battery, 900 k with Ni, and 9425 with lead giving a total of 10.5 M vehicles/year from a total of 60 M annually produced. The total Lithium reserves of 6.2-13.4 Mt will allow less than 14M vehicles to be powered, at all. 
         [0008]    There are believes that alternative battery strategy as ZnAir and NaNiCl are not resources constrained, but their fundaments are weak. 
         [0009]    The Electric Power Production 
         [0010]    There were 254M vehicles registered in 2007 in US only, traveling in average 12,000 miles/vehicle per year. If 50 kWh will deliver 200 miles, that means 3 MWh will be consumed in average per vehicle at 90% efficiency, driving to 760 TWh/year, while the entire US power production was of about 4,157 TWh/(year 2007). That will require an increase by 20% of the power generation, over the average growth of 2.x %. That calculation was optimistic and included the supposition that no battery material constrains would occur. 
         [0011]    Scaling this to Earth level, that with a population of about 6 Billions, 20× bigger than US that needs to be transported too, and introducing the climate change challenge that will bring a loss of 2% US-GDP/(year 2015), growing to 3% by 2024 . . . , etc. one can get the magnitude of the problem at planetary level. 
         [0012]    The hard outcome of this is that the transportation to be successful and to assure the economic needs and afford the Global Climate Change challenges has to drastically change. 
         [0013]    Batteries as Electricity Storage Related Issues 
         [0014]    In a superficial view over the electric vehicle this looks ecological, but it simply moves the pollution from the car exhaust pipe to the electricity producing plant and to the battery production chains. 
         [0015]    For the moment these are China, Chile and Argentina. In the future that spells “trouble” because US is not well placed at any of the classical battery materials and the dependence of foreign oil will be transformed in dependences of foreign battery materials. 
         [0016]    More, the US electric plants use a conversion efficiency of about 25%-30%, not far from the effective efficiency of the actual vehicles. The only difference will be the change of the composition of pure oil exhaust with the palette of US electricity production (more coal, that&#39;s worse than oil, with some nuclear, hydro and renewable, that we believe is good). 
         [0017]    Another simple calculation shows that if any vehicle will be equipped with a 50 kWh batteries-bank, and leaks 1%/day in average, from its initial charge, by residual discharge process the total capacity for a single loading per year equals: 250 Million vehicles×50 kWh/vehicle=12.5 TWh (3 times the total US electric production from 2007). 
         [0018]    To maintain a battery in shape ready to use but not using it, every 3-4 month recharge is needed, which equals 10 times US 2007 electricity production. 
         [0019]    This turns to be far worse than gasoline propulsion. 
         [0020]    The Grid Robustness 
         [0021]    The Advanced Electric Vehicle and EV vehicle advertisement says that to recharge it is enough to plug in and in 45 min. is charged. Now for 50+kWh in 45 min. is necessary an installed power of 100 kW, and one might use a cable by 5 times thicker than that from the dryer. Usual residences have an installed power of 20 kW, in average. 
         [0022]    A block transformer usually has less than 200 kW. 
         [0000]    Suppose the house e-car powering is solved, but more than two cars will overload the block transformer, and a blackout might be generated. As a factor of demand the US infrastructure and grid would need to be developed by a factor of 10. 
         [0023]    This is a huge collateral investment or a drastically reduction of the battery capacity from 50 kWh to less than 5 kWh, and to allow that some other forms of electric energy to be delivered by infrastructure to power the transportation. 
         [0024]    The Real Cost Affordability 
         [0025]    Usual consumers are looking to the equivalence between the consumption of electricity and gasoline and their cost ratio. Advanced Electric Vehicle a top of its kind takes about 50 kWh for 200 miles, while an equivalent gasoline vehicle makes for about 8 Gallons of regular gas. It seems by about 5 times cheaper to run electrical vehicle. 
         [0026]    In reality the classic vehicle needs lubricants, while the electric vehicle needs batteries. A good set of batteries take about 5000 recharging cycles, for a mileage of 1 million miles, at a cost of $50 k. A more accurate specific cost becomes cost of ¼ kWh+5-cent cost of battery per mile, plus some interest giving a cost equivalent of 1 kWh/mile. About the same as with gasoline. 
         [0027]    It is also proven that fast charging is reducing the battery life up to 5 times, and the equivalent cost will become higher than 2 kWh/mile (about 25 mpg equivalent). About the same, or a little bit more than the gasoline powered car. No ecologic progress, but pollution redistribution. 
         [0028]    Daily Range Bottleneck 
         [0029]    The “Advanced Electric Vehicle” may be considered a 90% of the technologic limit, that means about ¼ kWh for 1 ton-mile. The aerodynamic coefficient is as good as possible; the mass is as low as possible, not to much room for improvements here. 
       THE STATE OF THE ART 
       [0030]    There are 5000 years of experience with the wheel usage, and more than 150 years of automobile developments and patenting. All the ideas used in this approach appeared as separate ideas in various patents and applications before. 
         [0000]    The last most advanced developments presenting an interesting idea will be mentioned here from thousands of patents covering the automotive industry. 
         [0031]    There are solutions using light vehicles on bicycle wheels since 1883 from the Daimler Benz first patent to the actual Daimler Benz 2009 fuel cell-powered prototype. 
         [0032]    The “Go-Boy” multi-seat bicycle like vehicle for leisure and utility purposes are recently made following a car structure—rigid chassis carrying the payload and wheel suspension, that presents some propulsion issues. 
         [0033]    The GM-2009 ultra-aerodynamic unmanned vehicle speed structure looks good, reaches a lower than 0.2 Cdx but need a space for payload too. 
         [0034]    Carver 2009 develops the tilting tricycle vehicle bringing more stability and acceptable lateral acceleration in passengers and driver—but only the cabin tilts with the first steering wheel. That is the best that concept may deliver, being no real need to tilt the engine. 
         [0035]    The recent Brudelli P-mp3-500 is a motorcycle developed in an inverse carver structure with wheels and body tilting. Higher stability and comfort are achieved but the motor remained in the main body. 
         [0036]    The RAV industry developed a vehicle secondary under-car or rear mobile garage, starting a multi-modal agreement transport structure. 
         [0037]    The 2009 GM 2 wheeler conceived as New York City transport vehicle developed by with verticality assistance system is working at low speeds and is stabilization system critical. 
         [0038]    The University Of San Francisco developed a battery recharging station, solar powered that may recharge an electric vehicle in few hours while parked under the solar shed. 
         [0039]    The electric bike, scooter, motorbike are already in fashion, giving up to 40 mph speed exhibiting power shortages on slopes. 
         [0040]    The electric car is capable of higher acceleration than classical vehicles due to the higher low speed torque of the electric motor. 
         [0041]    The 2009 Aprilia Magnet brings an enhanced version of electric motor wheel. 
         [0042]    Lumeneo Smera designs a small 1-person vehicle for individual transportation that matches the case of an average 1.3 passengers per car in 2007 US. 
         [0043]    Mercedes Benz presents the 3628, a tilting 1-person vehicle. 
         [0044]    Honda for 2009 designs the Hermes Carver, a magnet wheel tricycle and an electric town tricycle scooter. 
         [0045]    The Mono-mobile  2007  idea of using a mono-rail vehicle to obtain higher mileage and transportation comfort shows an electric vehicle with the batteries, that count for 40% of the vehicle&#39;s weight integrated in the structure. 
         [0046]    The multi-modal concepts are in full development showing its advantages by the ROR (Rail and Road) developments. This is an old transport style, illustrated by the western movies about the cowboys traveling style. It was a kind of Multi-modal procedure. They took the horse with them in the train, sometimes in different compartments, and from the train destination station to their end of travel destination they made it on horseback. 
         [0047]    Several new concepts are available in present, but none fit on the future transportation requirements:
       one is fly and drive—that is based on the actual vehicles but its objective function is to save time, and another is   “city-go” with fix location car rental system, and foldable short mileage cars, where the user may not own but use them, with the disadvantage of the distance between users location and assigned parking spot.
 
Several things are clear about the electric vehicle:
   too big for a single driver 90% of time payload—by 4 times   it has the battery too heavy and central placed to be replaced or recharged in less than 1 h   it is an entirely tire based transportation   it is too expensive and unreliable with sophisticated highly educated maintenance that the society will not enjoy possessing individually.       
 
         [0054]    The present invention brings several concepts are that makes possible to further increase the efficiency of the transportation act, based on in-depth analysis of the dominant functions. 
         [0055]    The “street curve” says that the power or energy required for a transportation act is determined by the transported mass, its cross section, aerodynamic coefficient and speed. In spite this is a known fact for over 100 years very few thought to an in depth optimization to consider:
       transported mass have to be higher than the payload mass,   aerodynamic coefficient is usually 0.4 but not smaller than 0.2.   cross section has to be bigger than the payload&#39;s, and   speed can be reduced but creates discomfort.
 
That means that some optimization is possible but the “objective function” is very complex and have to become as reasonable as possible in order to obtain a real macroeconomic relief.
       
 
         [0060]    The new car and concept developed is based on a the following directive lines:
       Light car customized after the payload—with the mass as small as possible, and the cross section reduced to the minimal comfort and safety dimensions. A human payload, in taxido with its take-on airplane luggage requires a 2 m 2  cross-section, a 2.4 m length and a 1.2×1.2 m with-height dimensions (18 sqft; L×W×H=8×4×4 ft).   Making the car light is not the only objective—we are optimizing for 3 parameters at this stage, that says—be reasonably light, build with as cheap materials as possible to be safe and ecologically friendly. (Advanced Electric Vehicle is as light as possible but is not cheap or environmentally friendly—as constructive parts are hardly recyclable).
           The specific consumption analysis based on realities shown in  FIG. 19  that refers of the single passenger equivalent energy consumption using various transport modes:
               on tires for this payload with specific power train attachments is between 0.1-0.05 kWh/mile for about ¼ ton payload (lower than Advanced Electric Vehicle divided by 4)   On rail it may become as low as 0.01 kWh/mile. (5 times lower than on tires)   
               The market demands as a reflection of the society needs regarding the ownership, usage and maintenance of the new vehicles, where the private persons trend to minimize the investment in transportation vehicles.   
               
 
         [0067]    The new car concept has only a cockpit privately owned, as main embodiment of the invention, while the communities or federal organizations is taking the burden of very qualified maintenance and may own the propulsion devices. The individual rents them. That makes possible that the capacity of the power train on tires to be customized at the needed range, and terrain specificity. No more batteries added than usually needed plus a power reserve (solar harvesting, efficient gas generator, etc.) 
         [0068]    The main original elements of the present invention is that it separates the car mono-block structure in functional modules:
       batteries and propulsion;   connection system,   cockpit with life support system and universal coupling devices,   power harvesting system,   auxiliary functions (amphibious, underwater, flying) adaptors.       
 
         [0074]    Another very important embodiment of the present invention is the fact that cockpit has no autonomous propulsion capabilities, but will possess standardized capabilities of connecting to propulsion systems as: 
         [0000]    electric vehicle power train,
 
mono-rail,
 
rail,
 
multi-modal ROR (rail or road, with ferry transport capability),
 
cable, pull-band, Funicular, in road cable propulsion,
 
UAV flying platforms, Helicopter,
 
Amphibious and in special cases under-water.
 
         [0075]    The electric motors power will help it climb 30° slopes with low speed, but will have capabilities of boosting by in-road embedded cable traction. 
         [0076]    There are many other features described in the patent but one important is that the battery pack is easy to exchange—being low and lateral outside the vehicle, easy to extract and change with charged ones, without the need to apply life shortening grid demanding fast recharging procedures. A normal charging duration is between 4 to 10 h, which applies a more uniform charge to grid. 
         [0077]    Another important embodiment of the present invention is the home backup by the car&#39;s battery that requires that the house system to be compatible with car&#39;s backup capability and smart enough to separate the power source, in order to maintain the life support functions mainly. This includes a kit for house power connection to car battery backup and house power management during backup. 
         [0078]    The Gradual market approach is another embedded feature of the invention. If the acquisition of an electric vehicle requires house power system adaptation, and electric infrastructure, the investment in this solar-electric vehicle requires no special investments—it starts as a neighborhood vehicle, with 40 miles range covered by 2-8 kWh batteries. It recharges alone from its solar panels in 1-2 sunny days if not used. It may be recharged from home grid, and backup it at need. 
         [0079]    The vehicle according the US patent is attractive because it has the lifetime greater than 4 years, possible of being delivered at a low price. It has a ROI (return of investment of about 1 year for a gasoline price of $4/Gallon, and 2 years for a gasoline price of $2.50/Gallon, bringing an income by cost avoiding of between $4-12 k in 4 years. In this conditions will be attractive to be bought by individuals. Once on the market the multi-modal developments will become attractive to communities but they have to be ready to implement. 
         [0080]    The new multi-modal transportation will require no dedicated or drastically enforced energy grid development while the classic mono-block car concept with no multi-modal requires the doubling of the capacity to mitigate the fluctuation in demand. 
         [0081]    The above mentioned originality points are designed to transport 10 times more people than actual electric vehicle with the same battery capacity and the multi-modal propulsion developments aim to minimize the total ecologic impact by making 90% of the transport process to become directly grid powered, preventing excessive battery needs. It will require a combined effort from manufactures and communities to have such efficient system implemented. 
         [0082]    For example a high-speed magnetic levitation 2 ways monorail structure using direct grid power may cost only $1 M/mile, with lower environmental fingerprint transporting about 10 k people at 200 miles in one hour, reaching a door-to-door time of 2 hours in a 250 miles range. Actually only helicopter transportation systems can reach this for very few with 20× higher consumption than by a regular car. Compared to this the proposed system will be 1000 times cheaper. 
         [0083]    The performances of various multi-modal transportation systems are presented in  FIG. 19  with respect to the specific energy consumption per standard passenger (200 lb) and speed of the mode, showing by diamonds the actual performances, and by ellipsoids the present invention expected performances at a payload per total mass ratio of 50%. 
         [0084]    The actual market offers a large palette of vehicles mainly derivate from the actual car structures. Almost all suffer from the payload to vehicle mass ratio, and vehicle surface that impacts the autonomy or the mass of batteries. 
         [0085]    Compared to that the present approach is looking for ways to minimize the mass, the cross-section and to improve the aerodynamic coefficient. The result is a vehicle for individual transport based on electric propulsion with good autonomy and solar harvesting features. 
         [0086]    The actual invention is proposing a multi-feature modular solar-electric vehicle system that may revolutionize the transportation. Starting from a new vehicle concept that separates the functional systems and make them modular, accessible, and interchangeable producing a large diversity of customized transportation systems, optimally fit to meet the needs and requirements of individual and society. 
         [0087]    It starts smooth and small, at the low end of the market as a cheap neighborhood vehicle, good for reaching a 40 miles range, with solar harvesting system, possessed by people to perform inside community transport optimization, meant to reduce the costs. The community gradually will build routes for multi-modal vehicles, and own batteries and structures to be fit upon request on any trans-boarding vehicle. The states and federal organization will further develop multi-modal fast structures in order to assure the minimum time and cost travel. 
         [0088]    The mass production of this system will prevent the battery material crisis, energy peaking, followed by dramatic transport cost increase with backfiring on life standards, and robustness of the nation. As it was shown before the actual electric vehicle (EV) development is unsafe, driving to potential high economic perturbations with large consequences. The novel system prevents this crisis to happen assuring a smooth development, a continuous growth in transport efficiency and energy harvesting, and gradual development of the multi-modal infrastructure. In the last development stage this system will be preferred even to high-speed high performance transportation mean, for its higher effective commercial speed that none on road autonomous vehicle can reach. 
         [0089]    The system according the invention strengthens the infrastructure robustness for transportation purposes It will be accepted easily at the low end as an efficient transport system, with nice features, and developed by community and proving its performances. 
         [0090]    The modularity and multi-modality allows accessing various propulsion modes with an equivalent of about two persons showed in  FIG. 19 , where a transport-action may have up to 10 propulsion components. In  FIG. 19  various actual passenger transport means are represented by diamond points in (mileage; speed) coordinates in double logarithmic scale, correlating the transportation mode with speed and cost of energy. The domains of performances where the actual multi-modal vehicle may be are shown by ellipses, for the new vehicle carrying one passenger. This is why the predicted mileage is smaller by a factor of 2 from the actual mileage of the transportation mode analyzed. The new customized optimization equations of transport may be cost oriented, time oriented, energy oriented, and modeled with regards to safety and availability. One may observe that rail propulsion saves important energy and time having low environment impact and shows robustness to nature-elements aggression. 
         [0091]    The invention may assure transportation for all 300+ millions of US citizens, avoiding battery materials peak, mitigating the oil peak and not overstretching the electric power system development. It will also decrease the total transportation costs by a factor of 2 or more while increasing by the same factor the connectivity and connection strengths. The strength of multi-modal electric vehicle system comes from the fact that it is introduced gradually as a neighborhood cheap transport device grid or solar powered and gradually developed its capabilities to multi-modal transport, to recreational and amphibious vehicle. In several years the communities will learn by themselves about the utility of having rail cheap and fast transportation, the advantages of pull bands in the street to give shortcuts in mountain regions, the funicular mode advantages or on monorails. Airplane platforms or helicopter propulsion are few of the future potential options of an integrated strong connected transport system. Underwater is a rare possibility, for education and agreement mainly that may be developed to cover all the possibilities of use of the multi-modal device, while amphibious features are useful in may water shore areas. The most important is that the multi-modal features to be developed right and be mature to smoothly satisfy the market demand, and to provide the market and environment a reliable safe and sound business model. 
         [0092]    A future transport optimization may look like the example in table 1 
         [0000]                                                                                                                                                              TABLE 1                   Multi-modal transport versions analysis                Multi-Modal Transportation combination (see FIG. 1)   Effectiveness calculation            Version.

There are shown three possible ways to produce the transport by using the infrastructure with various decisions as function of the weight of the different criteria that matters in the decision making process to cover a minimal distance of 155 miles. It shows that version 3 is 100 times more expensive than version 1 and only twice faster, with lower safety figure. Version 2 might more acceptable as cost time and safety level. Safety figures are arbitrary, and remain to be evaluated practically. It will be obvious that most of the people will prefer to spend the equivalent of $1 and extra 1 h, to minimize the potential accelerations they may receive and make the travel on cheapest version. Only in special circumstances they will use the airplane or helicopter non-ecologic propulsion to shorter the time. By the time the system will be available the gasoline might cost 3 times more, and the real cost of the trip might be illogically expensive (the 1 h difference may cost over $100). And this is only a partial analysis; more factors will also count in individual decision-making process.
 
       ADVANTAGES OF THE NEW SOLUTION 
       [0093]    The present patent aims to combine various solutions in such a manner as to allow the following advantages be present simultaneously:
       have very low energy consumption, achieved by reduction of masses and surfaces towards the payload&#39;s dimensions.   have the necessary autonomy achieved by adjusting the storage capability according to the needs   have fossil fuel free propulsion based mainly on solar power achieved by integration of solar panels and grid power   have comfort inside as in the actual vehicles or better—achieved by separation of the vehicle constitutive modules, the cockpit being free of vibration and pollution, with enhanced life support capabilities   have faster “commercial” speed by multi-modal resource integration, by mainly transporting the cockpit in various multi-modal systems and propulsion platforms.   Have enhanced safety, and navigation systems achieved by the cockpit design and electronics integration on board   Have multifunctional capabilities as snow, mud and slurry, amphibious and under water usage capabilities achieved by shaping the modules according to the usage desire.

A rail wheel is 5-10 times more efficient than a tire wheel, while no bumpy rail saves more energy from being dissipated by shock absorbers. A tradeoff between speed and specific energy consumption will be made in each case.

         [0180]    General Modification of Transport Concepts
       The persons usually buy the cockpit, and in exceptional cases the batteries   The community owns the rest that is temporarily rented to persons for defined usage   The community may own the mono-rail computer driven taxi system having a trans-boarding at terminals from rail adapter to battery adapter A mono-rail high speed connection may drive up to 300 mph making the trans-boarding Santa Fe Albuquerque in 15 min or less.   The basic principle is switching the propulsion to get savings in time and energy, running mainly on electric power—having the capacity of pushing the individual transport cost lower towards the limit of 1 kWh/10 miles and even lower in combined multi-modal transport systems.       
 
         [0185]    The average electric energy needed to transport the US 300 mil. population by an average of 20 miles/day will become somewhere between 20-100 GWd, for an average power of 25 GW, acceptable for US actual development of electric power. 
       SUMMARY 
       [0186]    The “street curve” shows that the fuel or energy consumption depends on the mass of the car, call M where M is the net vehicle mass M v  plus the payload made of passenger mass and luggage M pl , the cross section on forward direction, call S x  multiplied by the aerodynamic coefficient call C x , the friction coefficients in the transmission systems giving a force call Ft(v), where v is the car&#39;s speed. 
         [0187]    To obtain a reduction it is necessary to act on all the parameters: 
         [0188]    Mass has to be reduced towards M pl , S x  has to be reduced towards S pl , aerodynamic coefficient that takes effect at higher speeds has to be reduced towards water droplet shape value, or better, speed have has to be kept moderate, up to 60 mph. 
         [0189]    Compared with a car structure it is possible to reduce the mass from 2 t down to ¼ ton, the aerodynamic coefficient and the rest of forces will remain constant and an increase of mileage of 4 times may be obtained, reducing the payload by 4 or by 2. 
         [0190]    Another source of reduction is the change of the gasoline tank—thermal engine that gives an efficiency under 30% with an electric battery bank—electric motor that gives an efficiency of 60%-70% and the elimination of transmission that takes up to 10% of the power, with electric traction that takes less than 5%. This will bring another factor of 2. 
         [0191]    Finally if that advanced vehicle was running with a 50 miles per gallon, it will be possible to run it now for a single adult person at 350-400 miles per gallon. 
         [0192]    A gallon of fuel contains 3.85 liters×40.5 MJ/litter=150 MJ=40 kWh. A bank of 30 batteries of 12V, 100 Ah, may deliver that. This becomes very heavy; therefore autonomy of 100 miles may be obtained for only 8 batteries, at a more reasonable weight. 
         [0193]    This autonomy may not be enough for about 5% of transportation cases. 
         [0194]    Making these vehicles suitable for multi-modal transportation can solve this. The vehicle may have devices compatible with a specialized crane from the multi-modal vehicle loader to easy couple and take the vehicle into a specialized container. 
         [0195]    The multi-modal transportation system is composed from a vehicle container and a passenger container traveling together on the same transport system, train, and trailer. 
         [0196]    The carrier vehicle may recharge the vehicles stored in container from its power source or may develop auxiliary systems. 
         [0197]    The electric vehicle has the size defined by the dimensions of the passenger trimed by the container dimensions. It will be 7 ft long and 3-5 ft wide, 4-6 ft tall, aerodynamic shaped cockpit. It will have the F1 protective features, and will have a C x  of 0.2-0.3 at a cross surface of about 18 sqft=2 m 2  loading a weight of 350 lb. and having a own weight of 100 lb. The total weight of the vehicle will be 600 lb-1000 lb loaded and 250 lb-350 lb unloaded. 
         [0198]    The structure is similar to a 2 electric scooters reduced at the traction train with a sidecar or cockpit structure mounted between them on a dynamically gravitational adjustment system. The structure have to be aerodynamic and impact resistant similar to formula 1 racing cars. 
         [0199]    The train structure may be as light as bicycle wheels or motorcycle wheels or scooter or even car wheels. The electric gravitational adjustment system helps the displacement in tilted surfaces and turns giving the driver a flying feeling. 
         [0200]    The solar panel above is reducing the aerodynamic coefficient by as much as 20% but brings a relief for electric power being suitable for many short distance trips without refueling. 
         [0201]    To increase the day light autonomy the vehicle may trail up to four very light solar energy harvesting carts trimmed at container&#39;s width in order to obtain kWw range power needed for its long distance displacement during the day in a 250 miles range.

       DETAILED DESCRIPTION 
       [0520]    FIG.  1 —Front rear view of the vehicle is looking almost the same being dominated by the aerodynamic shape of the body. 
         [0521]    There are two propulsion wheels systems made by the transformation of a two-wheeler (scooter, bicycle, motorcycle, or customized) vehicles chassis with the wheel and tire  101  having a variable size between 8-24″. The Wheels power structure  102  is made of a chassis holding the two wheels together similar to a motorcycle, bicycle or scooter body, loaded with the electric motors, suspension, braking systems and batteries banks. It is desired to put almost the weight near to ground to increase its stability. Therefore the most near structure is the scooter. It has the disadvantage of not performing well on rough terrain due to low ground guard, touching ground obstacles. These are the power modules. The power modules are covered by an aerodynamic profile case  104  with headlights  103  giving a low aerodynamic coefficient similar to o missile and the center of mass placed at about ⅖ of the wheel diameter. 
         [0522]    On the aerodynamic case there are multi-modal transporter adaptor structures as hook spaces and wheel lockers and fixed supports that once opened blocks the structure in place. That also serves as security features for the parked vehicle being key unlocked. 
         [0523]    The aerodynamic functional case, with multi-modal adaptor  104  also serves as stair for the driver and support of the solar panels. 
         [0524]    The lateral sunroof support  105  is rigid to the power train platform, tilting solitary, but is articulated on the roof by a top hinge  107  supporting the solar harvesting panel  106 . 
         [0525]    There are two identical power structures connected by a distributed parallelogram structure that allows them tilt parallel. The structure is made of more than two bridges two lower Elastic transversal bridge  108  and one or two upper elastic bridge  109 . The elasticity is moderate allowing shock absorption. In the center a structure connects parallel creating the central cockpit elastic fixtures with tilt follower system  1015 . 
         [0526]    This fixture contains shock absorbers and elastic suspension that decouples the resonance frequency of the transversal supports  108  and  108 . 
         [0527]    The external cockpit case  1010  has the capability to tilt parallel with the driving power trains. It has an aerodynamic shape, looking like an egg with continuous curved structure or in stealth format made of flat surfaces. It has am windshield  1011  connected to the access door that may have a sweeper. 
         [0528]    The cockpit door  1012  may be made lateral, bi-lateral or roof integrating the windshield. The cockpit reinforcement safety structures  1013  similar with what is used in formula 1 or avionics have the role to create an elastic deformable structure to absorb the impact energy and protect the driver. 
         [0529]    The Solar panels lateral supports adjustments  1014  have an important role in aerodynamics of the system as well in system compaction for multi-modal transportation. 
         [0530]    A very important feature is the tilt adjustment system  1016  that controls the verticality of the system on the horizontal ground  1020 , during turns in two wheeler style or tilted ground. This keeps the forces inside the support base the vehicle mainly skidding lateral in overspend but not rolling. A force parallelogram actuator  1016 , controlled by an electronic system, makes the adjustment of the weight and inertial forces. 
         [0531]      FIG. 2  shows the electric vehicle turning on horizontal surface  2020 . 
         [0532]    The tilting mechanism  2016  together with the longitudinal bushing in the transversal parallelogram makes that the force in the tires and wheel structure  201 ,  2011  to be equal giving minimal axial stress. 
         [0533]    The wheels power structure  202  and the head aerodynamic profile and lights  203 , contained in aerodynamic functional case, with multimodal adaptor  204 , with lateral sunroof support  205  are tilting parallel together, living the solar harvesting panel  206  mainly parallel to the ground with slight changes due to the top hinge structure  207 . 
         [0534]    The lower Elastic transversal bridge  208  and the upper elastic bridge  209  are moving parallel to each other making the central cockpit elastic fixtures with tilt follower system  2015  tilt according the adjustment made by the tilt adjustment system  2016 . This system compensates for the lateral forces but it has to be strongly enhanced to compensate for the longitudinal forces occurring during accelerations and slow downs. 
         [0535]    An enhanced structure is achieved using an upper support—elastic dumper and shock absorber  2030  that takes most of the cockpit weight. The external cockpit case  2010  will be supported in an reinforced roof  207  and the bottom support  2015  having lateral shock absorbers end of range stoppers and vibration dumpers  2031 . In this system the weight force  2021  acting on the cockpit&#39;s center of mass  2017  is combining with the centripetal force  2018  keeping the resultant force  2019  in the center of the rectangle base made by the four wheels  201 , 2011 . The windshield  2011  part of the cockpit door  2012  protects the driver on bad weather and allows air-conditioning system inside powered by the solar-panels  2014 . 
         [0536]    The cockpit reinforcement safety structures  2013  are used to support the insulation of the cockpit in order to minimize the heat exchange. 
         [0537]    The solar panels lateral supports adjustments  2014  provides good aerodynamics and shadow, helping the auxiliary water evaporation cooling system work better reducing the need for the electric compressor air conditioning system and saving electric power. 
         [0538]      FIG. 3  shows the vehicle on tilted ground  3020  with the wheel structure and tires  301  and wheels power structure  302  at different levels. The tilt adjustments system  3016 , applies forces in the parallelogram of force that applies it to lower elastic transversal bridge  308  and to upper elastic bridge  309  making the verticality of the car. 
         [0539]    Each head aerodynamic profile and lights  303  module with the aerodynamic functional case, with multimodal adaptor  304  are placed at different levels. The lateral sunroof support  305  and solar harvesting panel  306  are placed in a position on average parallel with the ground lateral tilt moderated by the top hinge  307 . 
         [0540]    The external cockpit case  3010 , including the windshield  3011 , cockpit door  3012 , cockpit reinforcement safety structures  3013  are maintained in a near vertical position, compensated lateral by the central cockpit elastic fixtures with tilt follower system  3015 . 
         [0541]    The solar panels lateral supports adjustment  3014  has an effective role in aerodynamic flow adjustment and car compaction during multi-modal transport. 
         [0542]      FIG. 4  shows the tilt adjustment system acting on a force parallelogram that can be at straight angle  401 , tilted right  402 , and tilted left  403 . It acts on the vertical arm by connecting the vertical rod  405  to it firmly and the horizontal arm by firmly connecting the horizontal rod  404 . 
         [0543]    The diagonal is adjusted by screwing the diagonal adjustable upper rod  406 , and the diagonal adjustable lower rod  409  into the gearbox reducer  408  under the control of the electric motor  407 . If it turns one way it shortens the diagonal therefore the structure tilts right, while turning in opposite direction the diagonal elongates and the structure tilts left. A controller electronic unit  415  drives the motor. 
         [0544]    The automatic tilt adjustment system  410  is composed of a gravity vector direction detector  411 , that has a right direction detector  412 , a left direction detector  414 , a tilt value transducer  413  and a processor unit  415 . 
         [0545]    The gravitational detector  410  may be made of a pendulum with electric contacts, a tilt sensor, with analogical output, or a combination of wheel force sensors. The signal is transmitted to an actuator-processing unit that takes the signal and generates the actuator signal  416  that controls the electric motor  407 . All the equipments are powered from the batteries  417  placed in the battery tanks. 
         [0546]      FIG. 5  shows a easy procedure to adapt a Bicycle/motorcycle structure to create the propulsion train for the vehicle in a perspective view. 
         [0547]    There are two bicycles motorcycles in parallel composed of rear wheels  501 , front wheels  5011 , the bicycle/motorcycle chassis or skeleton  502 . Transversal tubes  503  connected to skeletons by horizontal axis hinges connect these two units, allowing them tilt laterally maintaining the parallelism. 
         [0548]    A force parallelogram for tilt adjustment  504  is setting their lateral position by adjusting its diagonal. In the middle of the transversal tubes  503  is connected the cockpit support structure with tilt adjustment and shock absorbers  505  also using hinges. 
         [0549]    There are necessary more than two transverse bars from which at least one in front. The front transverse bar with horizontal hinge  506  needs to have such a profile to accommodate the front wheels turning space. A direction control system  507  connected to the front wheels by levers and to the stirring system  508  fixed on the driver&#39;s deck  509  allows the driver  5010  to set the direction. 
         [0550]      FIG. 6A  shows a bicycle/motorcycle structure adaptation system front view in order to see the transversal structure details. When it goes straight the rear wheel and tire  601  follows the front wheel  6011 . 
         [0551]    The chassis—skeleton of the bicycle/motorcycle  602  stays vertical. 
         [0552]    When the car takes turns  FIG. 6B  the front wheel  6011  turns and the transversal tube in horizontal hinge  603  is pushed by the force parallelogram for tilt adjustment  604  to follow the forces resultant. 
         [0553]    The cockpit support structure with tilt adjustment and shock absorbers  605  follows the skeleton tilt adjusting the position of driver&#39;s deck  609  and cockpit  6021 . 
         [0554]    The battery bank  6020  is placed as low as possible to lower the center of mass and increase stability. As a mater of evolution in vehicle technology, the system looks like a sidecar placed on two parallel motorcycles, but following the motorcycle behavior. 
         [0555]      FIG. 7  shows the electro-scooter adaptation system in perspective view, as an equivalent structure to the motorcycle or bicycle. The rear wheel and tire  701  id the drive wheel, but all wheels may be drive wheels. 
         [0556]    The chassis—skeleton of the scooter  702  is very low being an advantage on pavement as with the supplementary batteries on deck the center of mass comes very low, giving stability. The aerodynamic shape of a 3 ellipsoids is near fighter plane or missile value. 
         [0557]    The transversal tube in horizontal hinge  703  connected to the force parallelogram for tilt adjustment  704  adjusts the dynamic position of the cockpit support structure with tilt adjustment and shock absorbers  705 . 
         [0558]    The front transverse bar with horizontal hinge  706  stabilizes the direction control system  707  connected at the driver&#39;s deck  709  acting on the front wheel  7011 . 
         [0559]    The cockpit  7021  may be a single one placed in center or two placed on each scooter, with a single driving command. Up to 3 cockpits may be placed or a single several persons larger one may be attached on the power train. 
         [0560]      FIG. 8  shows an autonomous solar vehicle system made of a plurality of solar harvesting units on wheels. Considering the irradiance of one sun of about 100 W/sqft and the maximal surface of 7 f×5 ft=35 sqft and being irradiated with a power of 3.5 kW, from which it may harvest as electricity only 300 W in average, while each electric motor has about 700 W, maximal power, a need of another 3 extra panels is required to provide the necessary power for autonomous displacement under full sun, with an average speed of 40 miles/h, driving to a sun autonomy of about 250 miles/day. This may be completed with another 100 miles from the battery banks. 
         [0561]    The electric vehicle trailer  800  has the capability to trail 3-4 light carts, with the main purposes to carry modules less than 7 ft long and 5 ft wide that can be loaded in the multi-modular transportation container. 
         [0562]    The front vehicle is made of the aerodynamic power train  802 , having aerodynamic wheels front  8011  and rear  801 , each, the solar roof adjustable support  805  holding solar harvesting panel  806  that have some freedom in the roof hinge  807  that prevents the solar panel dynamic stress. 
         [0563]    The cockpit  8010  is almost unchanged but its lower transversal arm holds the hook for the carts. There can be up to four solar carts shorter than 7 ft. that have the capability of being packed one over the other on the roof. 
         [0564]    The first solar cart  8020  has the wheel forward  8021  being balanced by the hook, and the middle cart  8030  that has the light wheel  8031  placed on a median position. The last cart  8040  has the wheels placed at the rear  8041 . All these carts carry solar harvesting tile  8026 ,  8036 ,  8046  almost similar to those of the electric car in front  806 . 
         [0565]    The central cart may be design to accept some extra-luggage under the solar tiles having a specialized platform. The system has lateral wind dumper and people protection  8032  that prevents the trailer being raised by lateral wind, and a rear protection and wind dumper  8042 , that improve the aerodynamics and smoothes the system displacement. 
         [0566]      FIG. 9  shows an exemplification of multi-modal transportation system composed from modular cargo based on ROR Container 900 standardization, for road or rail  901 . 
         [0567]    The idea is that in spite the system has good equivalent mileage, it turns more effective to cover large distances with spread areas to use a specialized trailer to carry up to 10 vehicles simultaneously using a combination of rail and road. 
         [0568]    The travelers are embarking at one point and may be transferred on train without further changes, than back on truck up to destination. The container, is loaded on a standard carrier vehicle that have the wheels  902  of the carrier platform  903  that may be standard for rail or road. 
         [0569]    The standardized container may be split in two, a ¾ partition to load the electric car and solar carts  904 , and a ¼ partition for drivers of the carts. At their choice they may stay in the cart and sleep or come in the passengers&#39; partition  905  and spend the time. 
         [0570]    The passenger partition is equipped with a 8 ft multi functional door—stair  906  to allow the passenger get of the trailer or train in good conditions and windows  907 , having inside a multifunctional enclosure  908  for entertainment and comfort. 
         [0571]    The multimodal electric vehicles  904  are loaded in the trailer directly using a multimodal crane system  9010  gliding on multimodal crane sliding frame  9013  with pulley multimodal crane adaptor  9011  that can be connected directly to the vehicle&#39;s multimodal adaptors or may use the container&#39;s multifunctional door/ramp  9014  and for the upper stage a complementary platform with parallelogram crane system  9012 , that makes the vehicle or the solar carts be stored easily. 
         [0572]    The specialized door/ramp  9014  makes possible the usage of the system on any terrain without specialized loading/unloading ramps. The advantages of this system is that reduces the traffic, is increasing the autonomy and provides up to a factor of 3 higher travel speed. The disadvantage is that it reduces the capacity of the carrier vehicle by a factor of 5 to 10, which will be reflected in the transportation cost. A better alternative will be travel and rent electric vehicles for short local trips. 
         [0573]    For railway alternative is possible to use full multimodal electric vehicle containers and passenger wagons for electric car drivers together with the rest of the passengers. 
         [0574]      FIG. 10  shows the multi-modal electric transportation principle that makes this solution a competitive future alternative of long distance transportation on highway or railroad path or a combination rail and road  1001  with local spread area. 
         [0575]    The transportation coverage envelope  1002  is the resultant of the autonomous electric vehicles spread range integrating departure station electric multi-modal car autonomy surface coverage  1003 , intermediary station electric multi-modal car spreading range  1004 , and the terminal station electric multi-modal car spreading range  1005 . The electric vehicle spread range is done using the local roads  1006  in the limits of driver&#39;s residence or vehicle autonomy. 
         [0576]      FIG. 11  shows another embodiment of the invention related to the electronic control system  1100  equipping the vehicle, controlling one or more of the following functions: 
         [0577]    Dynamic Functions:
       a) tilt forward and acceleration  1101  is a special function presented only to the vehicles having two freedom degrees in the structure. The tilting forward is a fancy function mainly increasing the driver&#39;s comfort and equalize the weight among wheels. For rear traction vehicles that brings no advantage, reducing the maximum possible acceleration at the wheel skidding limit but favors the integral traction vehicles.   b) tilt backwards and slow-down  1102  is also a function present in luxury systems meant to male the driver to feel less forward acceleration give a favorable impact angle during accidents. It also activates the regime of generators in the driving electric motors recovering the power. When the break down acceleration request is high over the capabilities of the electric motors, the mechanical breaking system is activated and the adhesion control system assists the mechanical breaks.       
 
         [0580]    These functions are also dangerous for the vehicle if activated statically on express control it may require powerful actuators to perform the movement. In dynamic conditions first acted is the tilt actuator then the dynamic control function adjusting the acceleration to equalize the forces and put the resultant force in the middle of the base, and correct the position before the dynamic limitation occurs and requires more power in actuator. The forward tilt has to consider frontal wind component in the upper acceleration dynamic limits. 
         [0581]    An adaptive system detecting the limits of possible acceleration as driven by the wheel&#39;s adhesion have also to be set in place and limit the tilt at the right value. It limits the forces in the driver to undetectable variation in gravitational equivalent force in the 50% range by maximum ½ g.
       c) Tilt laterally and turning radius and speed  1103  equalizing the centripetal force, that is a function of speed and turning radius. In normal operation conditions a smooth turn in the steering wheel will translate in a tilt command and the wheels will follow the tilt as result of calculator. If the command to turn overpasses the capability to tilt the wheels will follow the turn command. At cheep versions the stirring wheel will act directly on front wheels while the tilt actuator will follow trying to get the right angle.   d) Impact and rolling modulus  1104  is controlling the pilot protection, acting the inflatable bags and the supplementary elastic fixtures in order to minimize the cockpit&#39;s accelerations. This modulus integrates the communication functions and driver assistance making automatically the necessary calls and recording the pre-impact and impact parameters.   e) Aerodynamics of the roof and carts module  1105  is measuring the force in the supports and smoothly corrects the position of the roof in order to have equal forces and no lift with minimal drug.   f) Power management and harvesting modulus  1107  is integrated in power control system, but as distinct circuit it refers to adjusting the battery loading in parallel with consumption keeping the solar arrays matched in the maximum power impedance value. It some evolved version an intermediary buffer battery may be added to allow higher fluctuations and power demands in electric motors.   g) Wind and drag/lift forces modulus  1106  is applied to cart panels. Being very light structure the cart has increased aerodynamic sensitivity following a tendency to fly jump or wiggle. Special wing profiles included in the lateral and rear protection will actuate making the flow laminar and keeping a constant weight with minimal vibrations. By this algorithm the driving improves in various wind conditions.   h) Cockpit air conditioning  11011  is a feature needed in winter and hot summer—the cooling/heating system is composed of a compressor based heat pump using electricity produced by the solar panel. An electronic system stops the heat pump when cockpit is open or the temperature differences turns in the acceptable tolerance limits. Secondary water-cooling cockpit systems may be used to save electricity where water is available.       
 
         [0588]    Static Functions
       a) Rolling surface horizontality modulus  1109  is a feature integrated in the lateral and frontal tilt systems making the car operate in highly tilt roads.   b) Energy harvesting modulus  1108  is a function active when the vehicle is parked loading its batteries. It balances the energy possible to harvest from sun with the grid charging capabilities integrating the harvesting predictions with the driver&#39;s demand. Other auxiliary power systems are integrated as grid charge.   c) Safety and security modulus is integrated in other functions group  11012  as a function simply detecting intrusions, vandalism or harsh weather manifested as high wind, hail rain when it acts protecting itself.       
 
         [0592]    i) Power management functions are integrated in modulus  1107 
       a) Battery charging from solar roof or from grid is treated by modulus  1106  it has the role to maximize when possible the harvested solar energy, but to have the batteries loaded at the desired time, set by the driver and agreed by the system.   b) Power backup for house system at special order  11010  is a special function to use the car energy for residential emergency backup. The delivered power will be in a battery compatible voltage in agreement with house system that has to limit its consumption to the needed functions and disconnect from the grid.   c) Battery banks status control is a function integrated in both safety systems  1112  and power management  1107  showing the status of batteries.   j) Other functions is a complex luxury module  1112  integrating a series of modern functions as:   a) Navigation that is done by GPS on satellite and cellular phone grid, inertial and acceleration control, speed control, and complex energy optimizer.   b) Driving assistance that makes mainly speed control, accelerations, skid control and automatic driving functions with obstacle detection.   c) Driver assistance refers to air conditioning system, air quality driver vital functions monitoring and alerts, route control.   k) multimodal functions are also integrated in other functions modulus  1112  and refers to supplementary electronic assistance for multimodal transportation referring at:   a) Loading-unloading procedures launched by external remote communication. All systems on vehicle are positioned in the optimal position as air conditioning shut down or paused, the wheels blocked the aerodynamic adjustments off, etc.   b) Transport security system, controls the accelerations inside and disconnects the power in case of hazards.   c) Charts assistance, represents a map transport function, signalizing the intent of the driver to get a multimodal ride, and scheduling as function of its distance in terrain and the capability or reaching the terminal. This is a wireless internet function on GPS or cell phone system.   d) Other computer functions and laptop specific integrated functions with voice activation and control may be used during automatic navigation.   e) The computer system has to have a distributed structure with universal command from cockpit and from external sources with smooth control transfer assured by standardization       
 
         [0606]      FIG. 12A  Shows the multi-modal electric vehicle floating on water  1200 . The power trains  1202  are under water surface having negative buoyancy using the wheels equipped with fins  1201  for propulsion and creating water jets  1215 . 
         [0607]    The connection system  1203  integrates the cockpit  1210  hydrodynamic designed with a supplementary floating structure  1270  giving an enhanced stability by placing the meta-center above the center of mass. 
         [0608]    The sun harvesting modules  1206  are above the water surface using the polls  1205  with adjustable height.
         FIG. 12B  present another embodiments of the present invention making a synthesis of potential multi-modal propulsion means.       
 
         [0610]    The vehicle is composed from the same basic modules the cockpit  1240  made in a stealth design or eggshell design  1234 . The poles  1235  and the harvesting panels  1236 . 
         [0611]    The propulsion modules  1232  having the extremities terminated by a headlight, position and direction signal lights  1237 . The wheels  1231  have tires and a finned structure  1241  coated in hydrophobic material as PTFE for water, mud or snow propulsion. The forehead  1232  is acting as a cutting blade limiting the size of the material underneath, mainly good for snow. 
         [0612]    The connection structure  1233  has multiple roles; it may hold and integrate the floating structure  1230  and hold the rail traction adaptors  1270 . Instead of traction adaptor in  1270  device may be placed the Electro-Magnetic wire pathfinder device used in automatic pilot navigation. 
         [0613]    For very tilted roads requiring high power motors this may be done by street integrated cable propulsion  1260  that draws the vehicle by cable  1261 . 
         [0614]    The propulsion modules  1232  have multi-modal adaptors  1244  used to support the entire vehicle structure in a specialized crane adaptor  1253 , having 4 cables or bars  1254  that are connecting to the multi-modal adaptors  1244 . The cable  1252  in a rail crane to be loaded in a multimodal transport vehicle—see FIG.  9 —may hang the structure or may be used in a cable transport system made of the support cable  1250  and the pulley wheel  1251 . The same system may be used in a monorail system. 
         [0615]      FIG. 13  shows a magnetic levitation propulsion system that may be used to carry the cockpit only or the entire structure. It is made of the profiled rail  1330 , the magnetic propulsion modules  1331  integrated in the structure  1332 . The structure has the power harvesting units trolleys  1333  at lateral connections or rails. 
         [0616]      FIGS. 14A  and B shows a foldable connection structure compaction for multi-modal transport or storage. 
         [0617]      FIG. 14A  shows an egg shaped module without flotation system compacted in a 2-3 ft width and 3-5 ft height ready to be stored or loaded in a multi-modal container. 
         [0618]    It is further possible to lift the wheels  1401  to gain the ground cart space but it is an option. The propulsion modules  1403  are coming one tear the other at few inch apart by folding the connection module  1404  keeping the cockpit on center and maintaining the displacement capability. The front and rear modules  1402  having the lights may also fold up taking the wheels off the ground. 
         [0619]    The cockpit  1410  is touching the modules  1403  and but leaves clear access to the multi-modal adaptors  1404 . The pillars  1405  holding the solar harvesting panels are also folding down making the solar panel  1406  fold and touch the upper side of the cockpit. 
         [0620]      FIG. 14B  shows a stealth shaped cockpit  1410  containing a floating module  1440  compacted. It also contains a rail training system  1431  attached in center. To be loaded in the multi-modal container it has to be connected by the crane adapter  1423  having hooks on cables  1422 . The entire system goes into a rail crane  1430  by the lifting cable  1424 . 
         [0621]      FIG. 15  shows a longitudinal section through the modular solar electric vehicle system. 
         [0622]    The vehicle contains two battery modules  1503  that have to be as equal as possible. When connected through the connection module the battery power regulators  1556  adjust the common power level of the vehicle. This power will be delivered to the cockpit and all the systems including the wheels  1501  motors&#39; regulators  1551 . 
         [0623]    The battery module  1503  is an autoportant/self-sustaining structure loaded with batteries.  1555 . The type and parameters of the batteries are further subject of optimization and customization. The batteries have included a smart diagnostic, power management and charging system  1558 , transferring power from grid, solar system or spare thermo-mechanical generators, even from a driver power by using a set of pedals generator/dynamo inside. 
         [0624]    The wheel module  1502  having the wheel  1501 , suspension, direction and electric motor for propulsion is connected in the fast locking fixture  1551 . 
         [0625]    The connection system/module  1504  is standardized and it may connect a large variety of propulsion trains. It has the tilting devices included in the structure. It also holds a protection grid front and rear formed with laminar aerofoils profiled grill  1514 . 
         [0626]    This grill has only collision role being mounted on the central axe  1515 . Under the battery module there are a set of support wheels, grips  1554  to aid easy coupling. 
         [0627]    The multi-modal adaptors  1559  are located on the propulsion trains, and they also contain the solar panel poles  1505 , that hold the solar array  1506 . The solar panels may be flat and producer independent  1506 , or may be profiled  1516 , to minimize the aerodynamic resistance. 
         [0628]    The cockpit  1510  is fixed in a standardized 3 points (or more in special cases) lockable fixture  1530  present underneath at the central axe  1515  of the connection system  1504 , and above the cockpit. This feature allows the fast coupling of the cockpit at various propulsion trains. 
         [0629]    The cockpit is conceived insulated from the power trains by a set of suspension and shock absorbers. The tilting will minimize the acceleration variation vector in the passenger bodies giving an air gliding feeling. 
         [0630]    The safety reliability and comfort are enforced from the concept. The cockpit  1510  has an aerodynamic or stealth outer shell that is connected up or down to propulsion or transport trains in the standardized fast locking fixtures  1530 . Inside the shell  1510  near the external fixtures  1530  a set of elastic vibration absorbing components  1521  are fixing the pilot/driver cage  1520  into a system designed to hold a uniform variation of acceleration during shocks or accidental impacts. During an impact the driver&#39;s cage  1520  is slightly sliding on the glides  1522  proportional with the acceleration, turning to minimize the uncomfortable accelerations in the driver&#39;s body. 
         [0631]    The front of the cockpit contains a shock energy absorbing material  1523 , which may also incorporate life support functions as ventilation and air purification. The cockpit&#39;s computing system with the necessary batteries  1528  are placed in a safe position being protected for electric shocks and other aggressions. The end side of the cockpit is aerodynamically terminated having an inflatable pillow  1529  for aerodynamic and back impact adjustments. The airflow  1511  is maintained as laminar as possible to assure the minimal aerodynamic resistance. 
         [0632]    The seat  1526  and the steering and controls  1527  are adjustable in order to best accommodate a 7 ft male  1524  or a 4 ft female or child  1525  head upper level. 
         [0633]      FIG. 16  also called options list or menu presents various configurations allowed by the advanced modularity. 
         [0634]      FIG. 16A  shows the battery propulsion train options. These refer to the propulsion wheels modules  1601  where the wheel type, radius, tire, and the wheel fin may be selected. The power of the wheel and the stirring  1603  may be also selected. It is possible to choose full propulsion and 4 wheels stirring. Chains of propulsion wheels may also be possible creating a 6,8 wheeler. 
         [0635]    The battery tank may be also selected  1602  customizing the battery capacity, type, voltage and other parameters. The connection system distance L may be also selected  1604  allowing a diversity of connection modules and adaptors. 
         [0636]      FIG. 16B  is referring to the connection module customization. The connection length L  1604  have to be decided and the cockpit connection type. Than the tilt freedom degrees  1623  may be selected from 0, 1, and 2 meaning rigid structure, lateral tilt and longitudinal tilt. The connection module may have a floating structure  1625  and a folding structure  1624 . On the bottom  1622  it may have a power module as rail, or cable traction or an electromagnetic cable follower, or street power loading trolley. 
         [0637]      FIG. 16C  shows some special options may be taken for amphibious and underwater applications. The propulsion module may have a hydro, mud, snow fin profiled wheel  1633 , may have an air cushion to glide on mud and shallow waters  1632  and for underwater it have to have attached the vertical and lateral displacement systems,  1634  and possible a remote arm. For all of these the cockpit and its computer has to be compatible. 
         [0638]      FIG. 16D  is showing the potential selections for the cockpit and solar panels. The cabin may have  1610  various types housing from 1 seat up to several seats—say 5, by adding an extension module  1611 , between the cockpit and the termination body  1612  that may hold the pressure cushion shape adaptor, luggage trunk, and rear impact protection systems. The safety design comes from inclusion of a rigid passenger cage in the cockpit shell, with the role of extending the impact deceleration range and dimming the deceleration to acceptable limits. 
         [0639]    The selection for the solar power harvesting system  1640  is complex, may decide between the flat or shaped panels, the efficiency, size, folding, manufacturer, buffer battery. 
         [0640]      FIG. 17  shows how the cockpit is mounted on a power train. 
         [0000]    The cockpit  1710  having the door  1711  has to be handled in such a manner as to have the emergency door access operational all the time. The cockpit has a set of handlers  1721  from where two men may lift and set on the train, being a light 100-200 lb structure. 
         [0641]    It has 3-wheeled foldable lockable legs  1722  for ease of movement and can be put on the power train  1703  by guiding on the locker axis  1715  until the lockers  1720  get into position and click on locking the system. The power train on it&#39;s wheels  1701  may be driven into the cockpit to make the coupling. An emergency unlock mechanism may be available from the cockpit to safely eject the cockpit. 
         [0642]      FIG. 18  Shows the Cost and Mileage as function of transport means made for real transport means using available statistical data. 
         [0643]    The single passenger equivalent transport efficiency chart  1800  is made using Internet available statistical data showing the efficiency of various transportation vehicles. On the left ordinate is given the cost per passenger per mile in (cents/mille) or [USD/100 miles],  1801 , and on the right ordinate is given the specific mileage or energetic equivalent consumption in mpg  1802  being different from the left ordinate by the cost of a gallon, for various types of transportation  1803 , generically called “modes”. 
         [0644]    The legend  1804  shows the difference between the two inverse proportional functions. 
         [0645]    The data have been sorted after the cost range for various transport systems  1805 . 
         [0646]    The thick arrow in the right is showing that the large bars are read on Cost logarithmic axis  1806 , and refers to all cost bars  1807 . 
         [0647]    The thin arrow showing that the mileage narrow bar is read on the mpg axes  1808  and refers to all Mileage narrow bars  1809 . The importance of this figure consists in showing the real values and their distribution for various very particular systems. This is an indication of what performances a vehicle type may reach shown by the ellipsoids  1805 . It also shows the basis of calculation for this invention. 
         [0648]      FIG. 19  shows the performance of the transport mode with respect to mileage and speed as an important classification criterion in a double logarithmic chart. 
         [0649]    The performance distribution of the transportation means  1900  is represented as function of transportation speed  1901  and mileage  1902  as important input data in invention development, showing the reality and the room for performance. The Diamond point  1904  is showing the position of the particular statistics data that appears in the previous chart at mileage and cost for equivalent person transportation with an average weight of 100 kg. From this data the domain of performance of the invention has determined as having the cockpit weighting another 100 kg, doubling the passenger mass, therefore reducing the mileage by half. 
         [0650]    The ellipsoid showing the domain  1905  represents the calculated possible performance of the multi-modal device, while the line  1906  shows the correlation speed-mileage for the respective transportation mode. The total transportation being a linear combination of the 10 identified in the chart by ellipsoids, transportation modes. 
         [0651]      FIG. 20  shows the main elements of air platforms propulsion attached system covering the modes A and H in  FIG. 19 . 
         [0652]    The cockpit  2010  with the passenger inside is the only part of the assembly that is transferred and connected to various propulsion systems using the multi-modal lockable fixture  2020 . 
         [0653]    To fly the cockpit in the future virtual air high-ways a flying UAV wing  2050  may be used that has the propulsion made by gas turbines  2051 , the only hard to replace propulsion, but being non-ecologic. 
         [0654]    Another type of flying mode is Helicopter like, and that may be achieved by connecting the cockpit  2010  to a helicopter skeleton structure  2060 , with turbo-fans propulsion  2062  driven by a motor-generator  2063  powered by a liquid fuel tank. Power levels above 200 kWe are required and direct internal combustion engine-gear combinations are competitive approaches to this application. To get this system functional a very delicate combination between the local cockpit computer and a central navigation system on ground have to be achieved.
