Description
- This application is a continuation of U.S. patent application Ser. No. 12/425,264, filed Apr. 16, 2009, and entitled, “Partially Self-Refueling Zero Emissions System”, which claims the benefit of U.S. Provisional Patent Application No. 61/124,469, filed Apr. 16, 2008, each of which are incorporated herein by reference in their entireties.
- The present invention relates to clean air engine systems, more particularly to clean air engine systems using water by electrolysis to generate the gases to fuel an internal or external engine, fuel cell or other device.
- Global warming has mandated a multitude of domestic federal and state regulations and international treaties all designed to limit the harmful effects related to the combustion of fossil fuels. These regulations generally target CO2 emissions, which have been acknowledged by some as contributing to atmospheric greenhouse heating.
- Over the past few decades different countries have experienced interruptions in the availability of fossil fuel supplies due to an external oil embargo and domestic natural disasters. In addition, countries face the lingering threat of direct energy terrorism targeted at our petroleum refineries and related infrastructure. Indirect threats also exist in the form of political/terrorist blackmail which may cut off access to any non-domestic source of oil supplies without warning. For example, the current rate of crude oil consumption in the United States is calculated to be approximately 12 million barrels per day. If an emergency forced the U.S. to become solely dependent on the United States Department of Energy Strategic Petroleum Reserve, (as of February 2008 the capacity was 698.6 million barrels) this national backup would be depleted in approximately 57 days. Obviously, such a scenario doesn't take into account the probability of fuel rationing nor the petroleum output of Canada and Mexico. It does, however, highlight the United States' acute vulnerability.
- Finally, some studies suggest that within 10 to 15 years the worldwide supply of crude oil deposits may be reaching the point of peak production, known as the Hubbert Point, after which supplies will steadily diminish followed by an ever-increasing cost to the consumer. The rise of crude oil prices from early 2008 to September 2008 proved to be burdensome for businesses and consumers worldwide. These prices may be mere hints of what will unfold when real crude shortages begin.
- Clearly, the issues described above suggest that continued dependency on fossil fuels is a tenuous course. As a consequence, a number of non-fossil fuel based alternative fuels are being evaluated and tested for transportation including ethanol, bio-diesel, electric, and hydrogen to name a few.
- Some manufacturers are pursuing electric and hybrid-electric vehicle alternatives. However, it has been suggested that a major drawback with increasing the number of electric and hybrid-electric vehicles in use is the large quantities of batteries to power the electric motors and other electrical devices. These vehicles use batteries of one kind or another (i.e., lead acid, lithium-ion, etc.) to store an electrical charge. If improperly charged, batteries can be permanently damaged. Additionally, if left uncharged for long periods of time, the batteries can sulfate or become unusable. Moreover, battery storage is heavy, space consuming, offers maintenance challenges and offers limited life. Batteries used typically for vehicles of the state-of-the-art have an average effective life of 8 to 10 years and must be disposed of after their lifecycle, thereby creating a daunting environmental hazard. Studies reveal that 20 percent of car batteries are discarded in land fills.
- Typical combustion engines are fueled by hydrocarbons. These combustion engines are generally used to power vehicles directly or are used to drive electric generators that provide power to electric drive motors. These engines have a standard efficiency of approximately 33 percent when fossil-fueled, and create pollutants such as carbon dioxide (CO2), carbon monoxide (CO), nitrous oxide and dioxide (NOx), and unburned hydrocarbons from combustion. Typically, aside from the estimated third of fuel energy converted to mechanical energy, another third is manifested into heat energy and the remaining third is expended into exhaust gas energy. By comparison, diesel engines are more efficient than gas engines, at approximately 40 percent. The addition of turbocharging and/or supercharging also increases efficiency. Fuel cell efficiency ranges from an estimated 50 to 60 percent.
- Hydrogen as a combustible fuel source creates no carbon-based emissions. Although conventional piston-type internal combustion engines can be modified to accept hydrogen fuel, the drawbacks are hydrogen pre-ignition and high levels of NOx emissions. Pre-ignition problems arise from hydrogen's low ignition energy, wide flammability range, and short quenching distance. The elevated NOx emissions are a result of mixing hydrogen with atmospheric air, which consists of approximately 78 percent nitrogen. The typical cause of elevated NOx numbers is a high compression ratio which is commonly used in hydrogen-fueled internal combustion engines to increase horsepower. NOx production in the combustion chamber can also be attributed to variables such as the air/fuel ratio, engine speed, ignition timing, and the presence of thermal dilution.
- Hydrogen engines can combust hydrogen which is drawn from pressurized storage tanks. These pressurized storage tanks are filled directly with hydrogen much like current vehicles are filled at a gas station. Fuel cell vehicles, also presently under prototype development and early market testing, call for similar fueling techniques. Hydrogen filling stations will be but a piece of a huge hydrogen infrastructure dedicated to hydrogen creation, shipping, storage and delivery. Such a hydrogen economy will necessitate a monumental public and private sector investment. Also critical are the dissemination of industry standards for fueling devices and safety regulations that include mandated training to ensure proper handling of this unique fuel.
- Hydrogen as a combustible fuel source may be stored in liquid form in a super-cooled liquid state or in the lattice of a metal hydride. The cryogenic system required to maintain the liquefaction is minus 253 degrees Celsius for hydrogen. The benefit of this approach is an estimated 10 fold increase in energy density (over compressed gaseous form) for both the fuel and the oxidizer. The liquefaction of hydrogen improves the energy density to within 20 percent of that of gasoline. The drawback of this method is the higher energy required to maintain the refrigeration system versus the energy necessary to compress the gases in the low pressure (0 to 1,500 psi) and high pressure (1,500 to 10,000 plus psi) tanks. While compressing the gas draws energy during filling the tanks and compression can be stabilized without additional energy, refrigeration requires a continuous energy output to preserve the temperature sensitive cryogenic state. In the event of a refrigeration system failure, the liquids innately revert back to a gaseous state which would require tanks of sufficient size to contain the gases. If the tank size is inadequate, then the rapid expansion from a liquid to gaseous state will likely result in a tank rupture and possibly an explosion.
- The option of storing the hydrogen as a solid in a metal hydride compound, nano-suspension or other solid form has drawbacks as well. The practicality of storing oxygen in this form, as it applies to the present invention, is unknown. In order to access the hydrogen stored as a solid, heat energy is required to stimulate the release of the hydrogen from its metal hydride compound, nano-suspension, or other solid state. Furthermore, as the hydrogen harvest nears depletion, it becomes more difficult to collect. The environmental impact of metal hydride disposal may be addressed by removing the hydride from the metal container and disposing of each separately. The storage of hydrogen in nano-tubes is, at this point, an unknown technology in terms of reliability, risks human and environmental poisoning, and after use, disposal pollution particularly to underground water tables.
- One ideal solution to the shortage in fossil fuel supplies includes a domestic energy source that has zero harmful emissions. Because of the vast demand for energy, such an energy source must be available in sufficient volume to meet the needs of the socio-economic marketplace. It should be derived from a source that is renewable in the most environmentally responsible fashion. That is, if possible, the cycle from production to disposal will be pollution free and non-toxic. Perhaps most importantly, as certain countries increase their development of solar and wind power flowing through an improved energy grid, these advances will actually reduce the consumer's cost of this new energy. As the present invention indicates, a strong contender for this energy source may be common water.
- In light of the problems and deficiencies inherent in the prior art, the present invention seeks to overcome these by providing a method and device to optimize the cumulative beneficial effect of harvesting all available forms of passive energy such as solar, wind, and hydropower. The cumulative energy that is recovered is converted to electrical energy which powers an electrolyzer to produce hydrogen and oxygen to fuel an engine.

While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be realized and that various changes to the invention may be made without departing from the spirit and scope of the present invention. Thus, the following more detailed description of the embodiments of the present invention is not intended to limit the scope of the invention, as claimed, but is presented for purposes of illustration only and not limitation to describe the features and characteristics of the present invention, to set forth the best mode of operation of the invention, and to sufficiently enable one skilled in the art to practice the invention. Accordingly, the scope of the present invention is to be defined solely by the appended claims.
- The following detailed description and exemplary embodiments of the invention will be best understood by reference to the accompanying drawings, wherein the elements and features of the invention are designated by numerals throughout.
- Hydrogen has a higher energy density per unit mass than does gasoline and other fossil fuels, but a much lower energy density per unit volume. For example, the energy density by mass of methane, propane, gasoline, diesel, and methanol is 14.27, 16, 17.1, 17.18, and 40.29 lbs/100 kWh respectively. By comparison, the energy density by mass of hydrogen and on-board oxygen is 49.6 lbs/100 kWh.
- In order to offset the lower energy density per unit mass, one embodiment of this invention relates to the cumulative benefits of recapturing all available lost forms of energy while the vehicle is in operation, including kinetic, friction, inertia, solar, heat and aerodynamic losses. Coupled with an optimized vehicle platform (i.e. lightweight structure, low drag configuration, reduced rolling resistance tires and low-loss wheel bearings) the overall vehicle efficiency increases to the level where it may have the potential to become partially self-sustaining. By harvesting energy losses, the proposed system will have the capability of generating fuel on-board the vehicle in the absence of an external power supply, such as a direct current electrical source to power the electrolyzer. The extent of vehicle's self-sustainability, or its capability to be mobile even while cut off from external supplemental energy, will depend on massive energy generation while in a static mode. In the event of natural disaster or any other interruption of fuel supply, the vehicle's partial autonomy could be highly useful. For example, an emergency vehicle after a hurricane when the electric grid is down and it is impossible to pump fuel or a military vehicle cut off from fuel supply lines.
- One embodiment of the present invention's capability to optimize stored energy capacity will rely on the cumulative benefits of absorbing and recapturing every minute source of available energy. While the actual energy savings from each device or system may range from micro-volts on up to substantial electrical output, the sum of the overall energy harvest should significantly reduce overall energy requirements of the vehicle designed for this system and those so retrofitted, as is practicable.
- While in static, non-operating mode, the vehicle will have access to multiple forms of energy to power the electrolyzer including solar skin, deployable solar awning, wind turbine, hydro propeller, and other means of generating energy. The solar skin will initially be constructed of state-of-the-art and near term solar technology which is effective only during daylight hours. As technology advances, the solar skin and deployable awning can be up-graded to full spectrum solar which will enable the system to capture infrared energy from the earth at night resulting from the sun's heat during the day.
- In a dynamic or operating mode, depending upon its configuration, the vehicle will have the benefit of one or more of the following examples of generating electricity to power the electrolyzer; inertia wheel generators, regenerative suspension components, regenerative shock absorbers, piezoelectric generators fitted inside the tires, piezoelectric wake generators located on the rear and undercarriage of the body, exhaust heat-driven turbine with generator, infrared electrical generation, other heat containment strategies that convert heat into electrical energy, and regenerative braking. Other practical means of generating on-board electrical energy may be later added as suits a particular application. These may include a more efficient means of completing electrolysis and other energy recapturing devices or means of energy generation not yet devised. By spreading these individual energy recapturing systems through isolated circuits, an element of redundancy is inherently built into the system. If one fails there are still other means of recapturing lost energy which will continue to be operational.
- One embodiment of the present invention utilizes water injection to cool the combustion chamber in order to eliminate pre-ignition of the hydrogen and oxygen fuel components. An additional benefit of water injection is its synergistic combustive properties with the hydrogen and oxygen fuel. It can be applied to produce more steam in the engine to create more power. The water can be injected with the hydrogen or oxygen. Alternatively, it can be injected separately into the cylinder head by another means. Aside from the high expansion rate of steam, it is thought that steam will help draw the heat from the internals of the engine.
- In accordance with one aspect of the invention, a metal permeating lubricant or high temperature resistant synthetic oil may be used to ensure proper lubrication of the rings on the cylinder walls and other moving parts in the engine. Further, in one aspect of the invention ceramic coatings and/or ceramic material may be applied in the internal moving parts of the steam exposed components of the engine as a strategy to protect engine parts from failure.
- It is believed that use of on-board oxygen when combined with the on-board hydrogen will result in a fuel mixture that can approach a nearly ideal, 100 percent combustion rate. Dry atmospheric air is comprised of approximately 21 percent combustible oxygen. The remaining air is 78 percent nitrogen and 1 percent other gases (argon, carbon dioxide, neon, helium, hydrogen, xenon, ozone and traces of water vapor) that are all inert and will not combust in conventional engines. The removal of these inert, non-combustible gases can give place to a like volume of highly combustible hydrogen and oxygen. It is thought that by varying the pressure of the injected fuels, small displacement internal combustion engines may be utilized to output substantial horsepower outputs, while retaining zero emissions. Because the present invention eliminates reliance on atmospheric air, the combustion of nitrogen and resulting harmful NOx emissions normally associated with engine combustion is eliminated.
- Given the fuel is completely combustible and the water injection will permit the engine to safely operate at a higher temperature, it is anticipated that engine efficiency may increase. According to mathematical calculations, an engine fueled by hydrogen and oxygen, with 14:1 compression ratio, will have an estimated 65 percent efficiency. This figure approaches the theoretical limits of the Otto Cycle engine which is close to 70 percent. The selection of the stoichiometric ideal fuel and/or water injection mixture, the compression ratio, timing and other means of enhancing engine performance will determine the actual thermal efficiency. It is believed that in certain aspects of the invention, additional components, such as turbocharging and/or supercharging units, used in conjunction with a closed loop system that includes steam-driven exhaust turbine generators, and other devices or systems that recapture wasted engine heat, will enhance the overall engine efficiency.
- In accordance with one aspect of the present invention, additional energy recovery components can be phased in and added upon as the commercialization of each component becomes available. Further, key elements of the core system (as shown in
FIGS. 1 and 2 ) can be retrofitted to state-of-the-art transportation, therefore rendering its emissions-reducing benefits more readily applicable for public use. The system can be phased in from conventional automobiles, trucks and other categories of transportation, to hybrid-electric vehicles, both parallel and series (FIGS. 3-5 ), to fuel-celled vehicles (FIG. 6 ). - In accordance with one aspect of the present invention, there are a number of advantages of basing the power train on internal combustion engine technology versus a fuel cell. First, the majority of vehicles in use, and about 99 percent of global manufacturing capacity and tooling, are centered around internal combustion engines (two and four stroke reciprocating, diesel, rotary and other types). As such, the high volume of worldwide production renders the internal combustion engine an economical unit to purchase and repair. Whereas fuel cells are an emerging technology, they are costly to produce and require expensive metals such as platinum.
- It has been reported that a zero-emissions fuel cell costs an estimated $1,000 per kilowatt output to produce. Conversely, a limited production, zero-emissions, closed loop internal combustion engine will cost close to $50 per kilowatt output to produce. Even if fuel cell prices drop 75 percent, selling at $250 per kilowatt output, which is not likely, a zero emissions small displacement engine in mass production could cost as low as $30 to $40 to produce. Second, conventional engines have a longer useful lifecycle than fuel cells and are not as sensitive to freezing or dry conditions. Third, an obvious case can be made for reparability. An internal combustion engine can be maintained or repaired by a dealer, local repair shop, or by an individual. On the other hand, fuel cell repair is a high-tech activity that is expensive and delicate. Lastly, sudden vibrations can damage the fuel cell membrane and fuel impurities can poison the delicate chemical balance of the fuel cell operating system. The issue of recycling thousands or hundreds of thousands of discarded fuels cells has yet to be addressed, as with the lack of hydrogen fuel infrastructure.
- While embodiments of the present invention incorporate a small number of energy storage devices as an energy buffer, the majority of the energy storage may be achieved through the means of compressed hydrogen and oxygen in federally certified high pressure tanks. In one embodiment, the size of the storage tanks are more naturally suited for use in connection with light or medium duty commercial vehicles. It is believed that these tanks have an estimated life cycle up to 20 years of daily use. When the high pressure, gaseous H2 and O2 function as an energy storage device, the weight savings over the most advanced state-of-the-art batteries can be substantial. For example, a commercial delivery vehicle that travels 150 miles a day consumes 750 KWh per day of energy (having an average of 8 miles per gallon). If equipped with the latest Lithium-ion batteries sufficient to generate an equivalent amount of electricity, the battery pack would weigh 8,267 pounds. By comparison, an equivalent energy amount of H2 and O2 gas stored at 10,000 psi weighs approximately 372 pounds. This weight savings will dramatically improve the range and performance of the vehicle. When the tanks become unserviceable, the carbon fiber wound safety cover can easily be removed and the aluminum tank can be recycled. An additional application of the core system before it is dismantled, is to use it for stationary power generation.
- During and after collision, safety cut-off valves can instantly prevent gas leakage. High pressure tanks have also demonstrated resilience to penetration by gunfire and large objects. They have also been proven to maintain safety even when placed in high temperature environments. Therefore, the use of low and high pressure tanks as storage for the hydrogen and oxygen is contemplated herein as one embodiment of this invention. Unlike batteries, which are sensitive to over or under charging, storage tanks can be partially filled or left unattended for years without adversely impacting their functionality.
- Certain embodiments referenced herein are applicable for use in connection with numerous engine technologies. Accordingly, it is contemplated herein that use of a dual-fuel or multi-fuel engine that is capable of functioning with another fuel other than the on-board hydrogen and oxygen could be implemented. This added functionality would serve as a backup source of power should any single source become depleted, due to a system malfunction, inadequate passive energy generation, or other cause. The dual-fuel and multi-fuel function could be achieved utilizing the existing or supplemental fuel injection system and a separate exhaust system. This back-up system will provide a redundant means for fueling the vehicle in an emergency situation.
- Referring now to
FIGS. 1 through 5 , in one embodiment of the present invention, a method of fueling and powering vehicles with zero-emissions and/or use of renewable fuels in order to reduce pollution is presented. In one aspect, this is achieved because water is used as a fuel source to power the system and water (steam) is the emission from the combustion. The system is a closed loop in which water is split into gaseous hydrogen and oxygen, and then combusted and condensed back into water. The closed system eliminates the release of steam and related water vapors into the atmosphere. - Throughout the figures and description of the invention, like numerals represent like components. For ease in understanding common elements of the system,
numerals numerals numerals numerals numerals 5 a and 9 a represent gas sensors, numeral 80 represents thermostats, andnumerals - Ideally, in order to achieve true zero emissions and not contaminate the closed loop nature of the system, trace residues of engine lubricants and minute metal fragments that become mixed in the combustion process must be removed from the water system before it returns to the
water tank 1. To reduce the lubrication requirements, low friction coated piston rings, ceramics, and/or other materials may be used in any or all parts of theengine 27. Lubricants that permeate the metal or nano-altered metals may also be applied. Because internal combustion engines require oil to lubricate, clean, and cool the internal parts, another embodiment of the present invention sets forth a method wherein trace residue mixed with the steam will condense and collect in asteam condenser 31 that also acts as a lubricant trap, and is designed to separate traces of engine oil and engine particles from the water. - In one embodiment, the present invention uses a
water tank 1 to store water. Water can be sourced from various means; rain water, condensation, tap water, recycled water and distilled water. Whereas all forms of water, excluding distilled water, would require filtering or purification, for simplicity, the preferred embodiment of the present invention will utilize distilled water. Thewater tank 1 may be linked to the engine heat to warm the water. The hotter the water at theelectrolyzer 3, the less energy will be required to complete electrolysis. Anelectrolyzer 3 is used to split the water molecules into their respective elements, hydrogen and oxygen. Theelectrolyzer 3 is capable of compressing the gases to 1,500 to 10,000 psi. This feature would eliminate the requirement for a low psi compressor. A reversible fuel cell, which is also capable of electrolysis, can be used as a Proton Exchange Membrane (PEM). Other state-of-the-art fuel cells are capable of electrolysis and are possible for use. In addition, future substitution of emerging technologies and those yet to be devised are also considered. Much like an electric vehicle, theelectrolyzer 3 can be powered by a plug-in auxiliary power supply such as 110-volt or 220-voltelectrical source - Passive means of electrically powering the
electrolyzer 3 include a solarcovered skin 14, a deployablesolar awning 15, or other solar device, all of which may be fitted with part or full spectrum solar technology, as commercialization permits. Low-cost nano, solar, or some other form or combination of solar/heat engine systems (e.g. Stirling Engine) to enhance the efficiency of the system are also applicable. Vehicles utilizing the present invention can be designed to be partially or completely covered with passive solar 14 technology that can be comprised of panels, thin flexible film, or paint that are permanently attached, bonded, detachable or added to the bodywork (e.g., roof, sides, front and rear) of the vehicle. Solar technologies include the state-of-the-art, emerging, and those types and forms yet to be devised. In addition, to help maximize solar absorption during the daylight hours, portions of the vehicle skin may also be automated to ensure the correct solar interface. That is, portions of the solarcovered skin 14 of the vehicle may be attached to a device configured to adjust the orientation of the solar cells in an effort to optimize solar energy production. For example, a large solar panel placed on the top of a semi-trailer or railroad car, may be equipped with a mechanism for adjusting the orientation of the solar panel in an effort to capture the maximum amount of available solar energy. - The benefits of a full solar skin, especially in vehicles with a large surface area can be very useful. Depending on the surface area of the vehicle and the efficiency of the solar technology, it is feasible to generate considerable electrical energy. For a 30-foot para-transit vehicle, the surface area represents approximately 900 square feet. The average U.S. house consumes approximately 10,000 kilowatt-hours per year. This equates to approximately 27.4 kilo-watt hours per day. It is believed that a solar panel rated at almost 13 percent can generate an equivalent amount of energy out of a solar panel with an estimated 300 square feet. Taking into account the effect of shade on one side of the vehicle or the other, under ideal conditions, the solar skin will be able to generate enough solar energy to power two average American homes. Assuming favorable weather conditions, it is believed that this equates to approximately one hour of free vehicle operation per day, depending on the size and weight of the vehicle. Further, when the vehicle is not in use, it is believed that the vehicle could “re-fuel” itself over time. That is, the energy produced from the passive means could be used to power the electrolyzer process discussed herein.
- Other passive means of energy creation include
wind generation 16,hydro generation 17, and other forms described hereafter. The exterior of the vehicle has covered ports which, when opened, access a socket head (or other means of convenient attachment) that may be fitted with a lightweight helical (or other type)windmill 16 and ahydro propeller 17 line which can be inserted into a moving water current. As a last resort, a human poweredgenerator 18 may be also fitted. The purpose of these units is to capture energy when the vehicle is at rest. If the daylight solar spectrum is used, then the supplemental wind energy and/or hydro energy may be used at night if conditions and location permits. Multiple ports could provide flexibility in selecting the best choice of passive energy. - Active or dynamic means of on-board energy recovery to create electricity to power the
electrolyzer 3 are sourced by kinetic, inertia, friction, thermal and aerodynamic devices. Referring now toFIGS. 3 through 6 , these auxiliary power sources may be a combination of any or all of the following:regenerative braking 21,regenerative suspension 35,regenerative shock absorbers 36,inertia wheel generators 47, flexiblepiezoelectric tread generators 37, exhaustheat turbine generators piezoelectric wake generators 38 and other lost energy recovery techniques. - In one aspect of the invention, the
electrolyzer 3 functions as both separator and compressor to place the two gases, hydrogen and oxygen, into separatehigh pressure tanks - The hydrogen and oxygen is delivered to an oxidizer/fuel ratio control module at a reduced pressure. There the hydrogen mixes with the oxygen and is injected into the combustion chambers where the gases are ignited and combusted to move the cylinders or turbine rotors (or whatever configuration internal combustion engine is utilized) thus powering the engine. Water injection atomizes the water vapor which is introduced into the engine with the flow of hydrogen or oxygen or as a separate process. Again, one function of the water injection is to cool hot spots in the engine which may result in pre-ignition. When the fuel ignites, the water residue will vaporize into steam adding power to the engine and providing a means for capturing the heat from the internals of the engine to be expelled during the exhaust cycle.
- Most hydrogen fueled vehicles rely on atmospheric air which is comprised of approximately 21 percent oxygen, 78 percent nitrogen and 1 percent miscellaneous gases (argon and other gases). As noted herein, the ultra-heating of nitrogen during the combustion process results in a chemical reaction leading to the formation of Nitrous Oxide/Dioxide (NOx). Although nitrogen is involved in the chemical reaction, it is inert and will not combust during the compression cycle. NOx is known to stimulate ozone production, a known contributor of smog in metropolitan areas. Smog, in high concentrations, can cause serious respiratory damage. Advantageously, fueling the present invention solely from the on-board H2 and O2 cylinders eliminates both carbon dioxide (CO2) and nitrous oxide (NOx) emissions. The result, especially given the closed loop nature of the system, is a true zero emissions vehicle. In one aspect, hydrogen is combined with approximately five times more oxygen than contained in atmospheric air. It is believed that the consequence is increased power output over that of a conventional gasoline fueled engine. Once the gases are burned, they combine again to become water in the form of steam and no pollutants are created. The steam created as an emission is condensed and recycled back into the
water tank 1. In one aspect of the invention, H2 gas and O2 gas are combined together with another inert gas (such as Argon) to moderate the temperature of the combustion process (or other related processes) within the engine. - If used in a conventional vehicle, the engine horsepower and torque are transferred to a
transmission 46 which, in turn, powers the drive wheels. In a parallel hybrid-electric vehicle (FIG. 3 ), an electric generator is inserted in front or behind the transmission before the drive wheels. In a series hybrid-electric vehicle (FIG. 4 ), the engine is linked to an electric generator that powers the wheel motors that drive the wheels of the vehicle. A fuel cell vehicle (FIG. 6 ) electrically powers the wheel motors that propel the vehicle wheels. It is also possible to construct a dual mode vehicle, which is a combination of a series hybrid and a fuel cell version (FIG. 5 ), to create a vehicle capable of silent running with a low heat signature. In all of these aforementioned applications, the present invention can be configured to meet the respective requirements. - In one embodiment of the present invention, the power train can utilize any type of internal or external combustion engine or other power plant that is fueled by hydrogen and oxygen and can be used to propel the vehicle in a conventional means with a heat engine powering drive wheels, in series mode (indirectly) and/or parallel mode (directly) or power the onboard vehicle systems in a non-operational mode (parked). One embodiment of the present invention will be of a modular design so modules can be replaced as the technology evolves and/or combined to suit the requirements of the end user.
- In order to provide flexibility in fueling, other auxiliary means of electrical generation are utilized to power the
electrolyzer 3. Depending on the purpose of the vehicle using the present invention, different electrical sources can or should be used. A standard among vehicles stationed at a home or commercial area is to use plug-in electric power from thegrid 40 in addition to the auxiliary on-board power generators to energize theelectrolyzer 3. A higheroutput base station oxygen cylinders - In one embodiment, a vehicle that will utilize the power system of the present invention will be designed to minimize aerodynamic drag and rolling friction. In addition to the benefit provided by the auxiliary power sources, vehicle weight should be reduced for further gains in efficiency. The synergistic effect of a lightweight, efficient vehicle in tandem with the wide complement of on-board energy recovery systems that will help offset the low energy density of hydrogen in comparison to hydrocarbon fuels.
- Advantageously, the present invention eliminates the need for a new hydrogen infrastructure for refueling hydrogen vehicles. In one aspect, the present invention implements an on-board hydrogen refueling system that will eliminate the need for hydrogen refueling stations and hydrogen transportation that the prior art needs to function. Another advantage of on-board fuel generation is enhanced safety. A system that eliminates a repetitive fueling process removes the chance of fuel leakage due to worn components or human error.
- Because the hydrogen and oxygen act as energy carriers, one of the benefits of the present invention is to reduce the battery and/or ultra-capacitor size. Since the use of chemical energy storage is limited to function mostly as an energy buffer, the size of the batteries and/or energy buffer is significantly smaller than a conventional hybrid-electric, or a pure electric system which relies solely on batteries. One objective of this approach is to reduce after-use waste (from the disposal of chemical batteries and toxic ultra-capacitors) which, in turn, will reduce ground pollution.
- Reduction in battery capacity is accomplished because in the process of electrolysis, the pressurized hydrogen and oxygen function as an energy storage device that has similar characteristics to a rechargeable battery. Powering the electrolyzer converts the water into hydrogen and oxygen that act as energy storage. As the hydrogen and oxygen are combusted in the engine their potential energy is converted to kinetic energy (energy carrier) to drive the engine and they are combined to become water that is recycled again.
- The primary obstacle of a pure electric vehicle is once the battery charge is depleted and no means of external charging are available, the vehicle becomes immobilized. The present invention shares some characteristics of an electric vehicle. Essentially, it is a plug-in, zero emissions and internal combustion vehicle (it can also be configured in the other variations as described above). Like an electric vehicle it can be depleted of its available zero-emissions on-board energy storage. However, unlike an electric vehicle, when fitted with an internal combustion engine (or other heat engine; diesel, rotary, turbine, etc) the present invention can be flex fuelled. That is, a separate fuel tank, fuel system and exhaust can be co-joined with the system to provide emergency mobility if any of the core systems malfunction or the fuel tank simply runs empty.
- Referring to
FIGS. 1 through 6 , thewater tank 1 is filled at thewater refill 43 and passes through thefirst water filter 2 with distilled water, tap water, stored rainwater or water collected from condensation. Water passes through anotherfilter 2 into the electrolyzer 3 (PEM or other type) where it is split into gaseous oxygen and hydrogen and pressurized. Theelectrolyzer 3 is powered from theenergy system controller 4 that distributes power from all the various onboard electrical power sources. - High pressure hydrogen from the
electrolyzer 3 flows into a high strength (1,500 psi to 10,000 psi), fire resistant, and impact resistant filament wound (or other configuration)storage cylinder 5 through thecheck valve 6,solenoid valve 7 andmanual shutoff valve 8. Similarly, high pressure oxygen from theelectrolyzer 3 flows into a high strength (1,500 psi to 10,000 psi), fire-resistant, and impact-resistant filament wound (or other configuration)storage cylinder 9 through thecheck valve 10,solenoid valve 11 andmanual shutoff valve 12. In the event it is determined that low pressure tanks (0 to 1,500 psi) are required, then the above will be duplicated utilizing two, lower volume hydrogen andoxygen storage cylinders - At night, or during non-use, an external source of electricity from the
grid 40, or created on site by fixed body solar 14, deployablesolar awning 15,wind 16,hydro 17, human 18, oraerodynamic wake 38 generators may be used to power theelectrolyzer 3 to fill thehydrogen 5 andoxygen 9 cylinders to partial or full capacity before the vehicle is placed back into operation. Similarly, thehydrogen 5 and/oroxygen 9 cylinders could be externally refueled or exchanged for filled cylinders onsite - According to one aspect of the present invention, the
hydrogen 5 andoxygen 9 storage cylinders, are placed in protective energy absorbingstorage containers 48 that is designed to provide additional safety in the event of collision. Another function of these containers is they will provide a means of trapping escaped gas from the storage cylinders. The storage containers could be filled with water to provide a medium for the stored gases to absorb into. On the inside and outside of these storage containers will be gas sensors and back-up gas sensors to provide redundancy in case of a sensor malfunction which will immediately shut down the process of electrolysis and the vehicle if a gas leak is detected. This will prevent any build up of excess gases in the storage containers. - In order to create the electricity required to power the
electric drive motors 21, the hydrogen and oxygen from thestorage cylinders manual shutoff valve controller ratio control system 26 where the gases are mixed and injected into the combustion chamber of theengine 27. The hydrogen internal combustion engine can be virtually of any kind (e.g., piston, rotary, turbine, diesel, etc.), including external combustion. As inFIGS. 5 and 6 , a fuel cell may also be substituted or supplement the heat engine. In a series mode, the hybrid power unit can also function like a generator, set to create electricity, but it will consume on-board fuel. - It is believed that the present invention, relying solely upon the on-board hydrogen and oxygen for combustion, will have near zero harmful emissions. Under this operating mode the only emissions through the exhaust will be heat and water vapor. The water vapor may be captured, condensed 31, and returned to the
water storage tank 1. As the present invention operates, the expended heat energy (steam) will drive aturbine 29 that drives agenerator 30 to deliver power to theenergy system controller 4. - In accordance with one embodiment of the present invention, there may be one or more steam turbines stacked next to each other or located on different points of the exhaust system. The function of the above-referenced steam turbines is to convert the super-heated steam into electrical energy. In one aspect, the lead turbine will speed faster, the second slower, and so on, until the last one hardly spins at all, which shows the energy has been expended from the exhaust system. In an additional aspect of the invention, a thermal container lined with
infrared cells 39 will surround theheat engine 27 and portions of the exhaust system. Theinfrared cells 39 convert the trapped heat energy into electricity to be fed back into theenergy system controller 4 to power theelectrolyzer 3. - In an additional aspect of the invention, unburned O2 and H2, still in gaseous form, are drawn out of the top of the
steam condenser 31 by afan 32. The levels of unburned H2 and O2 are analyzed by an H2/O2 sensor 33 which relays information back to theratio control 26. In one aspect, the relay, if required, changes the H2/O2 fuel mixture to minimize the amount of unburned H2 or O2 molecules. Remaining unburned H2 and O2 molecules are drawn back through to theengine 27 and fed into the combustion chamber to be burned more properly to form water molecules. - In one embodiment, a lubricant trap is fitted to the
steam condenser 31 to separate (by condensation, centrifuge, or other means) all traces of lubricant residue from the re-collected, condensed water supply. Provisions will be made to enable the collected lubricant to be removed and cleaned from thesteam condenser 31 and lubricant trap. - The residue H2O is collected and returned, through a filter to the H2O Tank 1. The previously described process enables the present invention to be a closed system, which means that all, or nearly all, of the H2O in the system will be recaptured thereby requiring little, if any, refilling of water into the system. To prevent freezing of the water supply in inclement weather, the H2O Tank 1 will be equipped with a
thermal container 49 and lined with an electrical heating element. This heating element will be powered by the energy storage container in theenergy buffer 34 when the thermostat within thethermal container 49 signals that temperatures are approaching freezing conditions. - In an additional aspect, to further protect the water lines from freezing, a
vacuum pump 50 attached to the H2 tank 1 will activate to purge the lines of their water content. Aside from eliminating the need to add water, a secondary benefit of a closed loop system is the removal of noise pollution from the exhaust process. - In one embodiment of the present invention, electricity flows through an
energy system controller 4 that will distribute power to theelectric drive motors 21. Theelectric drive motors 21 may be of a multitude of different types, including, but not limited to, DC, AC, brushless DC, air or liquid cooled. When the vehicle brakes or when the operator lifts off of the accelerator, theelectric drive motors 21 convert over to a regenerative braking mode. In this mode, theelectric motors 21 act as electric generators that recapture the kinetic energy used to accelerate the vehicle initially and transform it back into electricity. This regenerative braking electricity is returned to theenergy system controller 4 where it can be distributed to power theelectrolyzer 3 which in turn splits the water into hydrogen and oxygen to replenish the non-carbon-based on-board fuel supply or it may be stored in theenergy buffer 34 storage batteries until required by theelectrolyzer 3 or any other electrical device as noted herein. - In addition to the
regenerative braking 21, electrical energy may be derived frominertia wheel generators 47 placed on the rims of the wheels (inside the inflated area of the tires) or outside the wheel like a spinning hubcap (described in detail hereafter),regenerative shock absorbers 36 that are fitted with linear generators that re-capture the suspended motion of the moving vehicle, and/orregenerative suspension 35 components which are fitted with piezoelectric generators that brush against each other as the suspension pivots to create an electrical current. This supplemental electrical energy would also be received and distributed by theenergy system controller 4 to power theelectrolyzer 3 to further create H2 and O2 gas. Likewise,piezoelectric tire generators 37 are fitted to the inner liner of the carcass of the tires to capture the frictional energy of the moving vehicle. In one embodiment, the piezoelectric tire generators comprise one or more layers of piezoelectric fabric that flex or rub against each other to create current as the tire bulges when it makes contact with the pavement or surface of the ground. Thesepiezoelectric tire generators 37 feed recaptured lost kinetic and thermal energy through theenergy system controller 4 to theelectrolyzer 3 orenergy buffer 34. Other forms of electrical generation that can be installed on the vehicle, that have yet to be devised, from natural energy or other means, can be added in the future. - When out of service (e.g., in a parked mode) the present invention can derive power from the system described below to power the
electrolyzer 3. Detachable wind generator(s) 16 can be affixed into generator “ports” on the vehicle. A hydro-generator 17 can be placed in a moving body of water. In addition, as a last resort, a human-poweredgenerator 18 can be used. The on-board solar 14 and deployablesolar awning 15 will also provide a means of fuel generation utilizing theelectrolyzer 3. - In one aspect of the present invention,
solar panels 14 will be integrated or molded into the outer skin of the body. While photovoltaic cells have been available for a number of years, they are known to be expensive, prone to damage and difficult to maintain. Nano-solar cells which can be molded smoothly into the curved skin of the vehicle, as opposed to flat conventional solar panels are contemplated for use herein. Nano-solar strips can be likened to photographic film and is, therefore, substantially less per square foot in cost than rigid solar panels. In one aspect, the solar panels may be painted on. In this instance, the larger the external area of the vehicle, the more it will benefit from the solar effect. Also contemplated herein is the use of “full spectrum” solar cells which are designed to capture light invisible to the eye—from ultraviolet to infrared. This would also make it possible to refuel the vehicle at night. The entire exterior of the vehicle, including for example, the windows, could be covered with nano-solar technology. The vehicle exterior could also be configured to maximize the solar effect as the sun rises and sets during the course of a day. This means that the outer body could be automated to change the shape (that is non-structural). Asolar awning 15 can be deployed for more solar surface area. - In one embodiment, the
energy system controller 4 functions as the primary systems control for the entire drive-train, fuel supply, and auxiliary power systems. It receives electrical power from the primary and auxiliary power sources and distributes it where needed depending on the available supply of power from each of these sources and the current energy demand. Theenergy system controller 4 controls electrical energy flow to and from the motor/generators 21, theenergy buffer 34 and theelectrolyzer 3. It will monitor and protect theelectrolyzer 3 from irregular electrical energy flow and spikes and will also monitor power to the speed controller that, in turn, controls theelectric drive motors 21. - When out of use, the
electrolyzer 3 can be powered at any time, day or night (on-peak or off-peak), by plugging the vehicle into theelectrical grid 40. In the event that an H2 and/or O2 refueling station becomes viable, the H2 and O2 storage tanks 5, 9 could be filled at a base station from high pressure H2 and high pressure O2 tanks 41, 42. - Referring to
FIG. 3 , with slight modification, the hydrogen engine can be mechanically connected to the wheels to improve performance, through a clutch 44,transmission 46 and adriveshaft 45. It can also be fitted with a supplementary fuel system which would provide an emergency back-up to the hydrogen and oxygen on-board fuel system if it becomes depleted or the system malfunctions. - With reference now to
FIG. 8 , in one embodiment of the present invention, components described in sections above may be utilized to generate power in different forms, including electricity. The ability of current stationary systems for producing power which rely on alternative sources of energy, like solar and wind power, is subject to unpredictable weather patterns. Due to the nature of those systems, it is difficult and very expensive to store the value of the power generated from solar and wind-powered systems. In some instances, very expensive battery banks may be used to store energy produced during a wind event or during the day when the weather is not obscuring the transmission of radiation from the sun. - As noted, use of components described in the above sections in a stationary system will allow for the temporary “storage” of potential power. Specifically,
wind 16,hydro 17, geothermal 38 a, and solar-derivedenergy electrolyzer 3 may be equipped with a switch that responds to the detection of DC voltage, for example, received from an electricity producing component of any known solar or wind generating device. Water may be gravity fed to theelectrolyzer 3 through activation of a solenoid valve. The solenoid valve may be activated concurrently with the electrolyzer switch referenced above. Available water is passed through the electrolyzer and split into gaseous oxygen and hydrogen where it is thereafter pressurized and stored inavailable storage cylinders - In another embodiment of the present invention, an apparatus for generating power from the inertial movement of a wheel is contemplated. While use of the invention is described for use in connection with a wheel on the moving vehicle, any wheel which is subject to a rotational movement is contemplated herein.
- Referring now to
FIGS. 9 through 12 , in one embodiment, a device for generating electrical power from the motion of a wheel is disclosed comprising ahollow ring 53 having a plurality ofcoil members 55 disposed throughout thehollow ring 53 and amagnet 60 disposed within thehollow ring 53. Thehollow ring 53 comprises a light-weight material, including, but without limitation, polymeric materials such as polyester, vinyl ester, epoxy, polyimide, polyamide, polypropylene, and/or PEEK. In one aspect, thehollow ring 53 may comprise a composite material of fiber-reinforced thermoplastics or fiber-reinforced polymers. In one embodiment, thecoil members 55 are integrally formed within awall 54 of thehollow ring 53. Thecoil members 55 can comprise a conductive material (e.g., copper, aluminum, steel, and/or organic semi-conductors). While reference is made herein to asingle magnet 60, it is understood and contemplated that multiple magnets could be used as suits a particular application. The magnets could be aligned in series or disposed in a parallel orientation. - In one embodiment, the
magnet 60 comprises a solid metallic arched cylinder, wherein a radius of curvature of themagnet 60 is substantially similar to the radius of curvature of thehollow ring 53. In yet another aspect, themagnet 60 comprises a plurality of magnets laterally connected to one another with a hinge member. In one aspect, thehollow ring 53 is operatively coupled to theenergy system controller 4 shown inFIGS. 3 through 6 . - Faraday's law of induction (or the law of electromagnetic induction) states that the induced electromotive force in a closed loop is directly proportional to the time rate of change of magnetic flux through the loop. Moving a conductor (such as a metal wire) through a magnetic field produces a voltage in that conductor. The resulting voltage is proportional to the speed of movement; moving the conductor twice as fast produces twice the voltage. The magnetic field, the direction of movement, and the voltage are all at right angles to each other. A fixed conductor will also have an induced voltage if the magnetic flux in the area enclosed by the conductor is changing. During times of rotational acceleration or deceleration of the
hollow ring 53, themagnet 60 will move within thehollow ring 53. In one aspect, themagnet 60 will move within thehollow ring 53 opposite the direction of the rotational acceleration or deceleration of thehollow ring 53. In one aspect of the present invention, as themagnet 60 passes through thehollow ring 53, voltage is induced within thecoil members 55 of thehollow ring 53. In one embodiment, thehollow ring 53 may be part of a modular system that may be connected to the wheel of a car (e.g., as part of the hub cap). In another embodiment, thehollow ring 53 may be integrally formed with a frame of the wheel (e.g., as part of the rim of a tire), or attached to the existing wheel. - In one embodiment of the present invention, a plurality of
hollow rings 53 are operatively coupled to one another. In one aspect, a plurality ofhollow rings 53 having varying radii may be concentrically disposed about the same center point (FIG. 9 ). In yet another aspect, a plurality ofhollow rings 53 having substantially equal radii are disposed adjacent one another about the same center point (FIG. 11 ). - In another embodiment of the present invention, an inner surface of the
hollow ring 53 comprises a material having a coefficient of friction less than 0.1 (e.g., Teflon™). In another aspect, an inner surface of thehollow ring 53 comprises a material having a coefficient of friction less than 0.06. In yet another aspect, an outer surface of themagnet 60 comprises a material having a coefficient of friction less than 0.06. Advantageously, the material on the surfaces of thehollow ring 53 and/or themagnet 60 minimizes friction between themagnet 60 and thehollow ring 53 thereby promoting increased movement and efficient production of electrical energy. In an additional embodiment, an inner portion of thehollow ring 53 is vacuum sealed thereby minimizing friction between themagnet 60 and thehollow ring 53. - In an additional embodiment, the
magnet 60 further comprises a plurality of wheels operatively coupled to themagnet 60. In yet another embodiment, themagnet 60 further comprises a plurality of ball bearings operatively coupled to themagnet 60. Advantageously, the wheels and/or the ball bearings decrease the friction between themagnet 60 and thehollow ring 53. In one aspect, the wheels and/or the ball bearings comprise a magnetic material. - In another embodiment of the present invention, an apparatus for generating power from the flexing of a
tire 70 as it contacts the road, or other surface, is contemplated. While use of the invention is described for use in connection with a tire on the moving vehicle, any hollow object which is subject to compression against another surface is contemplated for use herein. - In a piezoelectric material, the positive and negative electrical charges are separated, but symmetrically distributed, so that the piezoelectric material overall is electrically neutral. Each of these sites forms an electric dipole and dipoles near each other tend to be aligned in regions called Weiss domains. The domains are usually randomly oriented, but can be aligned during poling (not the same as magnetic poling), a process by which a strong electric field is applied across the material, usually at elevated temperatures. When a mechanical stress is applied, this symmetry is disturbed, and the charge asymmetry generates a voltage across the material. For example, a one cm cube of quartz with 2 kN (500 lbf) of correctly applied force upon it, can produce a voltage of 12,500 V.
- Referring now to
FIG. 13 , one or more layers ofpiezoelectric fabric tire 70. In one aspect of the invention, the two layers ofpiezoelectric fabric tire 70 that will bulge from the contact with the road surface and flex or twist when the vehicle turns; either from front wheel or four wheel steering. As thetire 70 makes contact with the road surface, it bulges, depending upon inflation and the magnitude of the force put on thetire 70. When thetire 70 bulges, the two pieces ofpiezoelectric fabric energy system controller 4 to power an electrolyzer 3 (seeFIGS. 3 through 6 ). - In another embodiment of the present invention, at least one piezoelectric member (not shown) is disposed within an inner portion of a
tire 70, wherein the piezoelectric member is configured to approximate the normally biased curvature of thetire 70. The piezoelectric member may be disposed on only a small portion of thetire 70 or may be configured to substantially cover an entire inner surface of thetire 70. In one aspect of the invention, a plurality of piezoelectric members configured to approximate the normally biased curvature of thetire 70 are disposed within the tire. In an additional aspect, the piezoelectric material is integrally formed within the wall of thetire 70. In yet a further aspect, the piezoelectric material is used as the reinforcing members of thetire 70. - While any suitable piezoelectric material is contemplated for use herein, exemplary materials which may be used include quartz, topaz, tourmaline-group minerals, gallium orthophosphate (GaPO4), langasite (La3Ga5SiO14), barium titanate (BaTiO3), lead titanate (PbTiO3), lead zirconate titanate (Pb[ZrxTi1-x[O3 0<x<1), potassium niobate (KNbO3), lithium niobate (LiNbO3), lithium tantalate (LiTaO3), sodium tungstate (NaxWO3), and/or polyvinylidene fluoride (PVDF), and/or piezoelectric fiber composites (PFCs).
- More specifically, while illustrative exemplary embodiments of the invention have been described herein, the present invention is not limited to these embodiments, but includes any and all embodiments having modifications, omissions, combinations (e.g., of aspects across various embodiments), adaptations and/or alterations as would be appreciated by those skilled in the art based on the foregoing detailed description. The limitations in the claims are to be interpreted broadly based on the language employed in the claims and not limited to examples described in the foregoing detailed description or during the prosecution of the application, which examples are to be construed as non-exclusive.

Means-plus-function or step-plus-function limitations will only be employed where for a specific claim limitation all of the following conditions are present in that limitation: a) “means for” or “step for” is expressly recited; and b) a corresponding function is expressly recited. The structure, material or acts that support the means-plus function are expressly recited in the description herein.
