Patent for Sale:

Waste Heat Recovery to generate mechanical and/or electrical energy    

primarily for internal combustion engines but works with any waste heat source. used to increase efficiency and/or power output.


This system is available for existing vehicles as well as for any new vehicles that are currently being manufactured. It is applicable to any type waste heat source and is ideal for all current types of transportation equipment (existing or future), power generation, passenger vehicles, certain types of medical equipment and building management systems. This is the perfect answer to the new mandates proposed by President Obama, which will require all automobiles to decrease emissions in the next few years.

It is relatively inexpensive to manufacture and retrofit to existing engines and vehicles. It works with any type of fuel including biofuels, propane gas, diesel, or virtually any type of fuel and engine or device that generates waste heat. It can also evolve to function with new fuel sources as well as new sources of waste heat.

This system is capable of evolving as new engines are developed and can be used to bring the hydrogen fuel cell to a level of efficiency that would be marketable.

With the additions of 2 more patents issued in conjunction with the first this patent has become very broad and predates most patents currently being used my other manufacturers.

Frequently Asked Questions

How does it work? - This system captures the heat produced by internal combustion engines and uses it to pressurize a closed system. That pressure is used to turn a turbo (much like a turbocharger). But rather than use the turbo to compress air and feed that to the engine it is used to turn a generator.

In a retrofit system this electricity would be used to power hydrogen converters and supplement the existing fuel.

In a ground up construction the entire vehicle would be driven by electricity. The additional electricity produced by the energy recovery system would be used to supplement the power produced by the main engine and recharge storage batteries for the cold cycle. Once these batteries are fully charged the main engine shuts down and the vehicle operates off batteries. Various sized batteries can be used to provide a wide range of diving distances before recharging is needed. Once the batteries are exhausted the cycle starts over again.

What do you mean by relatively inexpensive? - Two prototypes can be built for around $1 million. This does not provide homologation but rather very good examples of how efficient the system can be for presentation to the industry. Once in production the cost to install the system per vehicle would be roughly the same as turbo charging an engine. The system is dependable over the long term and is very low cost to maintain.

How much will it increase performance and reduce emissions? - Considering the fact that an engine exhaust is about 650 degree Fahrenheit, a 6-cylinder engine would be able to produce enough heat to easily double fuel mileage. Diesel engine exhaust is about 900 degree Fahrenheit. This would be more than enough to double fuel efficiency. Once the system is developed to maximum efficiency it would be possible to more than double fuel efficiency. When combined with other hybrid technology the effects would be even greater. Emissions would be reduced in accordance with the reduction in fuel usage.

Do you have a working model? - We have had a partial working model in the past, and we were able to emission test that vehicle and get a measure of the drop in fuel consumption. The results from these tests back up the claims of improvements. A copy of these test results are available upon request.

How long would it take to manufacture it and have it up and running? - Between six to nine months would be required to produce two prototypes.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

It includes a motor in combination with its energy supply or its exhaust treatment. It also includes the motors, per se, combinations of motors, and elements specialized for use in such energy conversion that are not specifically provided for elsewhere.

Subclass 618: Motive fluid is vaporized liquid
Subclass 517: Unit of mass is a gas which is heated or cooled in one of a plurality of constantly communicating expansible chambers and freely transferable therebetween
Subclass 671: Motive fluid comprises a material other than steam or water

Class 62: Refrigeration

(1) processes and apparatus peculiar to removing heat from a substance, usually by a change of phase of a coolant or refrigerant, as by evaporation, melting or sublimation, (2) the resultant product of part (1), e.g., ice, liquefied or solidified gases, and (3) processes and apparatus peculiar to handling the latter as a stored product, not elsewhere provided for.

Subclass 238.3: With sorption
Subclass 238.7: Reversible, i.e., heat pump
