     Description of the Related Art 
     Typically, removing oil from tar sands (also referred to as oil sands), which are a combination of clay, gravel, sand, water and bitumen (a heavy black viscous oil) involves utilizing chemicals and/or water at high temperatures to release the bitumen bond from the clay/gravel/sand mixture. The hot water or steam changes the oil&#39;s viscosity, thus breaking its attachment to the clay/gravel/sand mixture. This traditional process uses vast amounts of water and ultimately contaminates the environment as a result of leaving trace amounts of bitumen to remain in the water and the tailings.

     SUMMARY 
     Systems and methods are described for extracting recoverable materials (e.g., petroleum and/or other hydrocarbons) from source materials (e.g., tar sands, coal, oil shale and the like). Source materials are introduced into a furnace. A condition is created within the furnace in which a gaseous pressure within the furnace is less than an atmospheric pressure outside of the furnace by removing at least a portion of air from within the furnace. Hydrocarbons contained within the source material are separated from the source material without requiring use of a significant amount of water by heating the source material to a temperature sufficient to cause the hydrocarbons to liquefy or vaporize. The liquefied hydrocarbons or vaporized hydrocarbons are then captured. 
     DETAILED DESCRIPTION 
     Systems and methods are described for extracting recoverable materials (e.g., petroleum and/or other hydrocarbons) from source materials (e.g., tar sands, coal, oil shale and the like). According to one embodiment a Plasma Oil Recovery from Tar Sands (PORTS) system is described that utilizes a hot plasma energy field to penetrate tar sands introduced into a plasma furnace. In various embodiments, the PORTS system uses no water, therefore making it very environmentally friendly. Instead the PORTS system utilizes a hot plasma energy field that penetrates the tar sands. This hot electrostatic-charged-molecule-separating-medium virtually boils off the oil from the tar sands. 
     As described further below, in one embodiment of a first configuration of a PORTS system, a tar sands pump forces tar sands into a crucible within a plasma furnace. Once the crucible is filled to the desired level, a vacuum pump removes all the air from within the plasma furnace, arc rods are positioned over the crucible and ignited with an arc of electricity to generate a plasma energy field. A Faraday coil energizes drawing heat and electrostatic energy down over every tar sand particle. The energy created by the plasma field vaporizes the bitumen clinging to the clay/gravel/sand mixture and forms a cloud within the plasma furnace&#39;s interior. The bitumen cloud can then be captured for further processing by opening a vacuum valve at the top of the plasma furnace. After the bitumen has been released from the clay/gravel/sand mixture, a disposal vacuum gate at the furnace&#39;s bottom opens as the crucible is mechanically turned over and the bitumen free mixture falls through the opening for removal. Once the bottom vacuum gate valve is sealed securely, the process can be repeated. The top valve is sealed and the vacuum pumps remove the air inside the furnace. The arc rods move over the crucible and ignite with an arc of electricity. The surrounding vacuum is energized and a ball of plasma energy is created. The Faraday Coil energizes drawing heat and electrostatic energy down over every tar sands particle and the bitumen is freed becoming a vapor cloud to be removed for processing. 
     As described further below, in one embodiment of a second configuration of a PORTS system, continual tar sands processing is provided by extruding pre-heated malleable tar sands down a long tray running through a plasma furnace. The tar sands slide along the open faced tray while being heated and energized by Faraday coils running beneath the tray. Heat and energy together create magnetic fields which draw plasma energy created by plasma arcs above the open-faced tray to harness the plasma field energy to heat the tar sands and create a vapor cloud of bitumen oil. Then, bitumen condensing on the interior walls of the cylindrical plasma furnace is collected by either a large doughnut shaped piston moving backward and forward through the plasma furnace or a forward turning doughnut shaped screw. As the tar sands travel through the length of the open-faced tray it eventually dries out and turns to powdery soil which empties into an augured collection pipe.

       FIG. 1  illustrates a batch processing plasma furnace  106  according to one embodiment of the present invention for extracting desired recoverable materials from source materials. Plasma furnace  106  represents a reactor chamber for carrying out processes in accordance with an embodiment of the present invention. The system  100  further includes a vacuum system  132  and  134  for obtaining the desired vacuum pressure where the vacuum system may be connected to a computer controller means for selectively controlling the pressure in the reactor  106 . The vacuum system  132  and  134  include at least one of the following roughing pumps, turbo pumps, diffusion pumps, turbo molecular pumps and the like, any combination of pumps may be utilized together or independently. The pump  132  is connected to the plasma furnace  106  via vacuum pump coil  134  to maintain a vacuum. 
       FIG. 2  is a cut away diagram of the plasma furnace  106  of  FIG. 1 . Inside the plasma furnace  106 , a crucible  210  is used to contain the source materials. The crucible  210  can have a large volume capable of processing at least one (1) and up to two point five (2.5) tons of material per batch processing. For example, the volume of the crucible  210  may be in the range from about 100-1000 ft 3 . The plasma furnace  106  has at least two openings, a top opening  228  and a bottom opening  124 . The tailings dump pipe  122  attaches to the bottom of the plasma furnace  106 . 
     The source materials for processing enter the plasma furnace  106  via pipe  103 . The means for introducing the materials to the depressurized chamber can be any number of methods. In one embodiment its can be a batch process that includes a hopper (not shown) for materials that are cyclically depressurized. In another embodiment, the process can involve a continuous feed system that allows materials to pass into the depressurized hopper. Similarly, the output can have a batch or continuous system. 
     The crucible  210  is attached to a large gear  112  for dumping the contents down dump pipe  122 . The worm gear  120  turns the large gear for dumping crucible  210  slowly. 
     Plasma rods  216  (e.g., an anode and cathode assembly) for generating plasma are inserted into the plasma furnace  106  at a suitable position. The position of the assembly  216  can be optimized for plasma production. The assembly can include an insertion and withdrawal to allow for control and to avoid damage during dumping of the crucible  210 . 
     The cross section of the chamber  106  shows refractory cement, which can be used to provide thermal insulation of the heat from the plasma. 
     Referring to the interior of the plasma furnace  106  and receptacle  210  for holding the source material to be processed. The receptacle  210  may include any combination of a container coated in a ceramic material, a solid ceramic container or any other container capable of withstanding the severe heat and process operating conditions. The receptacle  210  is heated by a heating means  208  (e.g., heating coils) for processing the loading material to a desired temperature. 
     The heating means  208  may include inductive coils, resistive coils or other suitable heating mechanism. Additionally, any combination of the foregoing heating means is also contemplated, for example, having inductive coils and resistive coils as the heating means. For example, the heating means  208  may include 2 to 4 inductive coils arranged around the receptacle means  210 . According to one embodiment, one primary coil and one standby booster coil are used. Finally, the heating means  208  may be computer controlled by a controller means. 
     Referring to  FIG. 1  and  FIG. 2 , the receptacle means  210  may include a magnetic means  218  (e.g., a Faraday coil) arranged on the outside of the receptacle means  210  for creating a magnetic field thereby promoting ionization. The magnetic means  218  provides confinement of electrons (along the magnetic field lines) thereby promoting a stable plasma around the receptacle means  210 . The magnetic means  218  may be arranged to form a three-dimensional area surrounding the receptacle means  210 . 
     In addition, referring to  FIG. 2  any number of magnetic field arrangements have been contemplated and may be utilized. For example, a first ring of individual magnets may be arranged in magnetic holders with their N-S polarities pointing in the same direction. While, a second ring of magnets are arranged below the first ring of magnets with their N-S polarities pointing in the same direction as the first ring of magnets. This configuration promotes a magnetic field into and around the receptacle means  10 . Any number of magnetic holders and magnets may be utilized. 
     Alternatively, an arrangement of magnets having a distorted magnetic field may also be utilized. For example, a first ring of magnets having N-S polarities pointing in the same direction. While, a second ring of magnets are arranged under the first ring of magnets having their polarities pointing in an opposite direction, when compared to first series of magnets. Accordingly, a distorted magnetic field is formed around the receptacle means  210 . Any number of magnet field configurations maybe utilized for promoting beneficial plasma around the receptacle means  210 . In addition, an electrical magnetic field generating means and/or a combination of magnets with electrical magnetic field generator means may also be utilized to form the magnetic fields. 
     Referring to  FIG. 1 , the receptacle means  210  is designed for receiving the source material to be processed and may hold approximately one (1) ton to two point two (2.2) tons of material to be processed. The receptacle  210  maybe surrounded by a heating means  208  that is connected to a power supply means for heating the material to a desired temperature. The power supply means may include a high voltage generator, RF generator, and the like. Additionally, the power supply means maybe connected to a computer controller means. For example, the power supply means may be connected to inductive coils, resistive heaters, and/or other conventional heaters. Additionally, the receptacle means  210  may be RF biased thereby promoting a bombardment of ionic flux onto the receptacle means  210 . 
     Further referring to  FIG. 2 , a movable pair of plasma rods  216  is arranged above the receptacle means  210 . In one embodiment, the cathode may be cooled with a cooling apparatus and connected to cooling plate for receiving deposits from the vapor phase. The cooling apparatus may include a heat exchanger and recirculating pipes. Any suitable fluid having the appropriate heat transfer properties may be used by the heat exchanger, for example, water and the like. 
     Optionally, the cathode and the cooling plate may be different geometric shapes or any combination of geometric shapes. For example, the cathode and cooling plate can be square, a diamond, a rectangle, a triangle, a hexagon, an octagon, and a pentagon. By utilizing the different shapes selective deposition onto the cooling plate can be accomplished. 
     At a predetermined time during the process, the plasma rods  216  may be turned clockwise or counter-clockwise or may move horizontally in and out of the plasma furnace  106 . For example, while loading the receptacle means  210  the plasma rods  216  may be retracted. When turning the cathode at different time intervals selective deposition onto the cooling plates is possible. As the desired recoverable materials have different thermodynamic properties, separation occurs at different times, therefore, at first time interval a first material may be deposited onto the cooling plate in a first position. At a second time after turning the cooling plate to a second position, a second material may be deposited on the cooling plate&#39;s second position and a third material may be deposited on the cooling plate&#39;s third position, and so forth. 
     In one embodiment, once the bitumen is vaporized the oil-bearing cloud inside the plasma furnace  106  may be siphoned off through a pipe gate valve opening  105  at the top of the plasma furnace  106 . 
     In operation, according to one embodiment, as the tar sands are pumped into the crucible  210  for heating, air is pumped out of the interior of the plasma furnace  106  to form a vacuum. The Faraday coil  218  surrounding the crucible  210  draws down and focuses the plasma&#39;s energy thus thoroughly engulfing each tar sand particle. As the Faraday coil  218  energizes the two arc rod electrodes  216  are extended down into and over the crucible  210 . High-voltage electrical current from these rods energize to create the high-temperature, low-cost plasma field. 
     According to one embodiment, clamps (not shown) on either side of the electrodes  216  releases either rod independently, in the case that one rod burns faster than its companion these clamps allow for fine adjusts to lengthening position and quick, easy removal and replacement of the arc rods  216 . Typically resistance, amperage control, and heat determine when the arc rod stepper motor engages. The anode and cathode rods  216  can be moved accurately down into the crucible  210  and back out again using friction from shaped top and bottom rubber-metal cylinders, for example. 
     According to one embodiment, after the bitumen is released from the rock mixture it is forced up and out through the pipe gate valve  105  on the top of the furnace for processing. The large vacuum gate valve  124  at the bottom of the furnace opens. The arc rods  216  are then withdrawn and the high torque worm gear  120  turns the crucible  210  over so the dry powdery tailings can be removed. The worm drive forces the crucible axels, along with the crucible  210  to dump its load of dry dirt. Finally, the lower vacuum-gate valve may be closed allowing the process to begin again. 
     The plasma furnace  106  may also have a number of heating sensors (not shown) selectively arranged within the interior and exterior of the plasma furnace  106 . These heating sensors may include, for example, thermocouples, thermometers, pyrometers, and other heat measuring devices. For example, thermocouples may be arranged on the skin of the plasma furnace  106 , the outer skin of the receptacle  210  and/or the cooling loop. 
     The plasma furnace  106  may also include optical sensors (not shown) for determining the color of the plasma and these sensors maybe connected to computer controllers. The sensors may also include various different color filters, infrared sensors, CCDS and the like. For example, an optical sensor coupled to a pyrometer and CCDS could transmit a video signal to a video monitor a digital temperature read out and a color sensor. The video monitor would allow an operator, for example, to determine visually that the system is operating in an optimal mode while the digital temperature read out and the color sensor send digital information to the analytical computer which communicates with the machine computer allowing the system computer to control the process. 
     Optionally, the sensors may be calibrated and connected to the computer controller for monitoring the wavelengths and changes of wavelengths emitted by the plasma. It has been found that the wavelength of the plasma can be correlated with the type of source material being processed. Therefore, by using a series of feedback controllers connected the computer controller selective material recovery is possible. 
     In addition, by utilizing the sensors, the processing time of any batch of material can be reduced—as the sensors can be configured to find a particular type of desired recoverable material. For example, the sensors and the process may be calibrated to recover a specific material. By monitoring the color of the plasma, utilizing feed back controllers and the computer controllers the process can be adjusted in real time to maximize the recovery of a predetermined or selected material. Accordingly, the process time may be shortened and the overall throughput of the process becomes more efficient. 
     An alternative embodiment, providing for continual processing of source materials will now be described with reference to  FIG. 3  through  FIG. 8 . In the context of the present example, the system  300  is described in connection with a process for removing bitumen from tar sands. 
     In the present example, the system includes a tar sands pump  305  and a plasma furnace  323 . In one embodiment, the plasma furnace  323  is corrugated on the outside for strength and is smooth on the inside for oil vapor condensation. Tar sands are delivered from the tar sands pump  305  to the plasma furnace  323  via tar sands pump pipe  309 , which may be made of high-pressure steel or the like. 
     In one embodiment, the tar sands pump  305  is a cement pump and includes a pair of hydraulic or pneumatic pistons  302  and  304  and a tar sands loading bin  306 . The pistons  302  and  304  are alternately filled with tar sands from the loading bin  306  and pump tar sands into and through an S-curve switching pipe  307  within the loading bin  306 . In this manner, continual pumping of tar sands may be accomplished. 
     According to one embodiment, before the tar sands are introduced into the plasma furnace  323 , they are flattened by an extruder pipe  311  to allow proper baking. 
     Within the plasma furnace  323 , the flattened tar sands are pushed along a tray  625  (see  FIG. 6 ) that travels through an interior portion of a large hollow screw  519  (see  FIG. 5 ) that is configured to scrape, move and otherwise clean the condensed bitumen from the interior of the plasma furnace  323  by pushing the condensed bitumen to a bitumen collection lip  545  (see  FIG. 5 ), which leads to a bitumen delivery drain  339  beneath the plasma furnace  323 . The screw  519  is turned forward by a planetary gear  753  (See  FIG. 7 ) which is engaged with three drive belt screw gears (e.g.,  749   a  and  749   b  (see  FIG. 7 )). 
     According to one embodiment, the screw  519  is manufactured of a light weight material (e.g., aluminum cast) to accommodate desired dimensions and throughput of the plasma chamber  323  and provide for a flexible interface to scrape the bitumen vapor from the interior surface walls of the plasma furnace  323 . According to one embodiment, the screw  519  may be capped with a carbon fiber material to add strength and flexibility. 
     In one embodiment, a bitumen collection gutter  621  (see  FIG. 6 ) is formed on within the outer edges of the screw  519 . In one embodiment, a block of aluminum is milled to form the scraping edge of the screw  519  and gutter  621  as one. Depending upon cost constraints for the particular implementation other materials may be used. 
     A suspension bridge  751  (see  FIG. 7 ) within the plasma furnace  323  holds up and positions pairs of arc rods/plasma rods (e.g.,  747   a - n  (see  FIG. 7 )) above the tray  625 . In a typical implementation, the suspension bridge  751  is both a non-conductor and heat resistant. The plasma rods  747   a - n  create an energy efficient heat source for vaporizing bitumen contained within the tar sands. A faraday coil  743  (see  FIG. 7 ) is located on the underside of the tray  625  to focus the plasma energy created by the plasma rods  747   a - n  evenly through the tar sands. 
     In one embodiment, the flexible edges of the screw  519  neatly clean the furnace&#39;s cylindrical interior much like using a rubber spatula on a smooth mixing bowl surface. 
     Whatever small portion of the bitumen vapor does not condense on the interior wall of the plasma furnace  323  can be sucked away down the bitumen oil drain  339  along with the liquid bitumen. Waste gases can be filtered by waste gas filter  337 . 
     In one embodiment, the outer edges of the screw  519  include carbon fiber tips e.g.,  841   a - b  (see  FIG. 8 ), for scraping bitumen from the interior wall of the plasma furnace  323 . Bitumen collection gutters, e.g.,  621   a - b  (see  FIG. 8 ) may also be formed at the outer edges of the screw  519  to drain away oil from the top half of the cylindrical furnace&#39;s apex or interior roof. In this manner, oil is prevented from contaminating the tar sand on the tray  625  and the row of arc plasma rods  747   a - b  positioned over the tray  625 . 
     According to one embodiment, the screw  519  turns in one direction only to force the collected vapor bitumen to the front end where it is collected and drained for processing. Friction from such a massive screw can be alleviated in several ways, for example, by having two central located axels at either end or creating a light weight screw wherein the weight of the screw is simply supported by contact with the interior edge. The free oil inside the plasma furnace  323  and the oil condensation act as a protective coating cutting friction by coating the inside with a non-stick oil surface. 
     A high-torque electric or gas powered motor  313  rotates the large doughnut hole screw  519  by turning a fan belt  315 , which drives the three drive belt screw gears (e.g.,  749   a  and  749   b ) by driving corresponding gear hubs (e.g.,  317   a  and  317   b ). The doughnut hole or screw&#39;s interior has a planetary gear  753  (see  FIG. 7 ) at the back end that is turned by the three drive belt screw gears  749 . 
     According to one embodiment, an auger  527  (see  FIG. 5 ), powered by an auger motor drive  333 , is provided at the end of the plasma furnace  323  for removing tailings by sending them down a disposal tube  331 . 
     In operation, S-pipe  307  inside tar sands storage bin  306  moves from one piston  302  receptacle to the other  304 . As the pistons  302  and  304  draw back, they fill with tar sands and as they push forward the tar sands are forced into the S-pipe  307 , then on through to the plasma furnace  323 . The bitumen soaked sand, clay and gravel fill the tar sands loading bin  306 , then the pistons  302  and  304  pump the tar sands in long tube  309  where it feeds the plasma furnace  323 . 
     According to one embodiment, as the pistons alternate between being pulled back and being pushed forward, the S-pipe  307  is simultaneously hydraulically turned so that it matches the filled piston&#39;s receptacle opening. The filled piston moves forward filling the S-pipe  307  allowing tar sands to proceed to the plasma furnace  323 . The tar sands are then pumped along pipe  309  leading into the plasma furnace  323 . The length of the pipe and the oily texture of the tar sands create a purposeful blockage which acts like a valve allowing the creation of a sustainable vacuum inside the plasma furnace  323 . 
     In one embodiment, the processing of tar sands involves going from tar sand ore that begins in a cylindrical form and is introduced to the plasma furnace as a flattened extruded layer in the form of tar sands paste. In one embodiment, an extruder pipe  311  reinforced with extruder type metal flattens the roundly formed tar sands down to a flat layer for proper backing within the plasma furnace  323 . The extruder pipe  311  would typically be formed from a heavy duty metal (e.g., 3/16 inch thick highly polished chrome, stainless steel or the like). 
     After the tar sands is flattened or extruded by extruder pipe  311 , the tar sands layer is forced by the pump  305  to continue down the tray  625  (see  FIG. 6 ). In one embodiment, the tray  625  may be tilted down by three to ten degrees to allow gravity to aid in moving the tar sands along. According to one embodiment, the tray  625  is tilted down at a five degree angle. 
     Depending upon the particular implementation, source materials, desired recoverable materials and processing conditions, the tray  625  could be coated in Teflon. Alternatively, if the heat from plasma rods (e.g.,  747   a - n  (see  FIG. 7 )) would otherwise flake away such a Teflon coating, the tray  625 , which is open-faced at the top, could alternatively be constructed of a highly-polished stainless steel or the like. 
     Heat generated by the plasma rods (e.g.,  747   a - n ) and focused down through the tar sands by the Faraday coil  743  (see  FIG. 7 ) thoroughly bake the tar sands at about 400 degrees Celsius and creates a bitumen cloud of vapor which is collected, or condensed on the interior of the plasma furnace  323 . The interior surface of the furnace  323  can be coated in Teflon because the temperature, due to the size of the diameter of the plasma furnace, helps cool the vapor for condensation. In alternative embodiments, the interior surface of the plasma furnace  323  is not coated in Teflon as the slippery vapor is a lubricant that helps prevent friction on the surface edge of the screw  519  (see  FIG. 5 ). 
     According to one embodiment, as the large doughnut hole screw  519  turns, it scrapes the bitumen from the interior walls always moving forward to the collection trough  545 . 
     Advantageously, a continuous bitumen extraction process is thus provided. As long as bitumen-laden material is fed into pump&#39;s hopper and continues to move along for extruding, heating, vaporization and disposal, oil production can carry on twenty-four hours a day. 
     Those skilled in the art will recognize various alternative structures for collecting the condensed bitumen from the surface of the interior walls of the plasma furnace  323 . For example, in one alternative embodiment, the long drive screw  519  can be replaced with a large doughnut-shaped piston which moves back and forth pushing/scraping the condensed bitumen from the surface of the interior walls of the plasma furnace  323  into bitumen collection troughs located at both ends of the plasma furnace  323 . 
     In alternative embodiments, in addition to or instead of utilizing a plasma energy field to heat the source materials, conventional heaters and/or heating elements may be employed. For example, inductive heating may be used to heat an electrically conducting tray or container on which or in which the source material resides. Resistive heating and/or heating by thermal radiation may also be employed. The electricity to power the conventional heaters and/or heating elements may be sourced from the national grid or by an on-site power station powered by the off gases of the processes. Use of solar and wind power generation could also be used.
