08/28/06 Power Generation Using Thermal Gradients Maintained by Phase Transitions Protect the approach of using phase transitions (melting, evaporation) to establish the hot or cold side temperature and heat source/sink of a thermodynamic engine. Early patent, could have value for LNG re-gasification and thermal storage applications.

08/28/06 Power Generation Using Low-Temperature Liquids Protects the approach of using a cold liquid to maintain the cold side temperature and heat sink of a thermodynamic engine, while using the evaporated form of the liquid (the gas) as a combustion fuel to establish the hot side temperature and heat source of the engine. (e.g., H2, CH4) Early patent, could have value for LNG re-gasification applications.

04/13/07 Power Generation and Space Conditioning Using a Thermodynamic Engine Driven Through Environmental Heating and Cooling Protects the SolarFlow System concept. Thermal energy collected from the environment (e.g., solar thermal collectors) provides heat to a system that delivers it to any of the following systems under customer/controller direction: space heating, water heating, auxiliary heating uses, power generation. The cold side of any power generation system is also maintained through transfer of thermal energy to an environmental heat sink. Earlier patent on using Stirling engine in solar combined-heat-and-power applications. Not current business direction.

Issued: 10/5/10

04/13/07 Displacer Motion Control Within Air Engines Protects the concept of direct electronic control of displacer motion on Stirling engines in order to maximize conversion efficiency.   Typical engines use mechanical linkages to effect sinusoidal-like motions of displacers.   More optimal displacer motions could be affected via direct (non-mechanical) control of displacer motion. Earlier patent, applies most easily to gamma and beta configurations.

11/21/07 Direct Contact Thermal Exchange Heat Engine or Heat Pump Protect the concept of using a liquid spray of lubricant liquid to deliver and remove heat from a Stirling cycle machine. This approach is most useful for low-temperature engines in which the adiabatic heating and cooling approximations are the most inexact. Concept not currently implemented due to complexity of piqued handling.
