Abstract: The invention described herein provides new devices suitable for effectively converting relatively low temperature differences into useful work (e.g., for generating electrical power), related systems, and methods of using and developing such devices/systems. The devices are characterized in, inter alia, comprising an at least partially enclosed moveable component (e.g., a piston), a closed pressurized gas system comprising sizeable void spaces, and a closed temperature modifying liquid system having portions that obtain temperature characteristics from two sources, which are alternatingly dispensed as droplets into the pressurized gas, creating a pressure/temperature difference in the gas which causes the moveable component to move back and forth along a stroke distance that does not include the void spaces, the pressure of the gas and liquid being at substantially balanced when the device is ready for operation.

Abstract: The process provides constant electric power from a combination of a wind energy generator and a firm secondary generator. The wind energy generator and the secondary generator supply electricity directly to a utility transmission system. The secondary generator must be able to provide power on demand that will meet a utility's needs. The secondary generator is preferably a natural gas turbine, but may be a hydrogen fuel cell, a diesel internal combustion engine, or any other similar technology.
