| The present invention is directed at the thermodynamic property amplification of a given thermal supply, provided by hydrocarbon combustion or in the preferred application heat provided by low-grade geothermal energy from the earth, for a vapor power cycle.

The heat-exchanger (boiler) supercritical gaseous mass flow segregated by a counterflow vortex tube (or bank of vortex tubes) forms hot and cool fractions where the hot temperature is raised above the heat-exchanger supply temperature, and heat (enthalpy) is added to the cool stream thereby increasing the cool temperature to that of the heat exchanger supply temperature. | ||||||

| 112 | Air motor power drive system | US12283380 | 2008-09-11 | US08561424B1 | 2013-10-22 | Michael Posciri; Charles Posciri |
| Several air motors are powered by a refrigerant that is pressurized to drive an alternator or generator. The electrical output can be used to propel a vehicle or to drive any type of operating system for land, air or sea based systems. The system uses a dual charging system to move pressurized gas that is then injected into an air motor. The gas is then exhausted and condensed back to a liquid. The liquid is stored until it is needed. It is then heated back into a gas, and fed back into the air motor in a continuous cycle. Several of these systems can be installed and connected to a planetary gear system. | ||||||

| 117 | HYBRID CYCLE SOFC - INVERTED GAS TURBINE WITH CO2 SEPARATION | US13382033 | 2010-06-09 | US20120117979A1 | 2012-05-17 | Emanuele Facchinetti; Daniel Favrat; Francis Marechal |
| A new gas turbine-fuel cell Hybrid Cycle is proposed. The fuel cell advantageously operates close or under atmospheric pressure and is fully integrated with the gas turbine that is based on an Inverted Brayton-Joule Cycle. The idea of the invention is to capitalize on the intrinsic oxygen-nitrogen separation characteristic of the fuel cell electrolyte by sending to the Inverted Brayton-Joule Cycle only the anodic flow, which is the one free of nitrogen. In this way the flow that expands in the turbine consists only in steam and carbon dioxide. After the expansion the steam can be easily condensed, separated and pumped up. Therefore the compressor has mainly only to compress the separated carbon dioxide. This effect generates a substantial advantage in term of efficiency and enables separating the carbon dioxide. The new proposed Hybrid Cycle enables to: substantially increase the system efficiency compared to the known gas turbine-fuel cell Hybrid Cycle, maintain the fuel cell operating under or close to atmospheric pressure and separate the carbon dioxide. | ||||||
| 118 | Highly efficient heat cycle device | US11579268 | 2004-06-01 | US07658072B2 | 2010-02-09 | Noboru Masada |
| A high-efficient heat cycle device formed by combining a heat engine with a refrigerating machine, wherein steam generated in a boiler is cooled by a condenser after driving turbine, built up by a pump, and circulated into the boiler in the form of high-pressure condensate. Refrigerant gas compressed by a compressor is passed through the radiating side of a heat exchanger for cooling after driving the turbine to output a work, and built up by a pump to form high-pressure refrigerant liquid. The high-pressure refrigerant liquid drives a reaction water-turbine to output a work and is expanded and vaporized to form refrigerant gas. The refrigerant gas is led into the compressor after being passed through the heat absorbing side of the heat exchanger and the condenser for heating. | ||||||
