Patent number: 12123325Abstract: A system for controlled recovery of thermal energy and conversion to mechanical energy. The system collects thermal energy from a reciprocating engine, specifically from engine jacket fluid and/or engine exhaust and uses this thermal energy to generate a secondary power source by evaporating an organic propellant and using the gaseous propellant to drive an expander in production of mechanical energy. A predictive control circuit utilizes ambient and system conditions such as temperature, pressure, and flow of organic propellant at one or more locations. The predictive control module regulates system parameters in advance based on monitored information to optimize secondary power output. A thermal fluid heater may be used to heat propellant.

Patent number: 12071866Abstract: A power generation system includes an Organic Rankine Cycle (ORC) electric generator thermally coupled to a stack of industrial heat pumps (IHPs). The ORC requires heat to generate electricity. The IHPs require electricity to generate heat. The IHPs have an efficiency much greater than 100% because some of the output heat from an IHP is pre-existing heat extracted from available source water, The temperature of the source water can be as low as 70° F. By configuring the IHPs to maximize their efficiency, the electricity required to operate the IHPs can be reduced below the output electricity from the ORC. The surplus electricity produced by the ORC is available for export. This coupled ORC/Heat Pump system is an electric generator that requires no fuel to operate and produces no emissions. The required energy is provided by the heat extracted from the source water by the IHPs.Type: GrantFiled: November 2, 2023Date of Patent: August 27, 2024Inventor: Joel M. Levin
