Dave Lackstrom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060186669
    Abstract: Thermodynamic energy methods and systems that provides all electrical energy and heat needs of a single residential house, commercial business or office building. The system is small enough to be stored inside the house or building. The system can generate excess electrical energy which can be sold over a power grid and allow for the house owner, building owner or energy provider (utility company) to provide income. The method and system can have combined energy conversion efficiency up to approximately 97%. Components can include amorphous materials, and the mono-tube steam generator boiler which is explosion proof when punctured, and only emits a puff of steam when punctured. The tubes can be built to pressure vessel code. The invention can use steam generators to power A/C units, domestic hot water, hot water air space heaters, other loads such as pools and spas and underground piping to eliminate ice and snow. Additionally, the invention can be used to power vehicles such as cars, and the like.

  • Patent number: 7019412
    Abstract: A closed loop system for generating mechanical energy at high efficiencies. The system can have a heating source, a superheater, an expander, a receiver, an absorber, a desorber, and regenerator with pumps and controls. The superheater heats a working fluid (a refrigerant or steam). A positive liquid/vapor expander expands a low temperature refrigerant, or steam vapor to the saturated state (having both liquid and vapor parts) utilizing a low-pressure sub-atmospheric exhaust sink. An absorber, generates a low-pressure sub-atmospheric sink using chemosorption which involves the exothermic reaction/absorption of ammonia refrigerant in water. The desorber is used to reconstitute inlet vapor (for reuse) and the regenerator recovers heat generated by chemosorption. The system can meet electrical power needs for residences, businesses or office buildings. The system can supply electrical energy to power grids, and can be an alternative power generation plants.

  • Publication number: 20040007879
    Abstract: Thermodynamic energy methods and systems that provides all electrical energy and heat needs of a single residential house, commercial business or office building. The system is small enough to be stored inside the house or building. The system can generate excess electrical energy which can be sold over the power grid and allow for the house owner, building owner or energy provider (utility company) to provide income or additional electrical generating capacity and the ability to sell/provide co-generated heat. The method and system can have combined energy conversion efficiency up to approximately 97%. Components can include amorphous materials, and the mono-tube steam generator boiler, which is explosion proof when punctured, and only emits a puff of steam when punctured. The tubes can be built to pressure vessel code.
