Abstract
The thermodynamics of an engine require that there be a source of energy (usually in the form of heat) from which energy is taken, processed to convert this heat energy into useful torque (energy) on an output shaft, and the energy returned to a lower temperature sink. The amount of useful energy that a thermodynamic engine can transfer to the process fluid from the heat source is some proportion of the difference in the energy available between the source and sink, and the efficiency of converting the process fluid energy into useful output shaft torque. This renewable energy source thermodynamic engine manipulates the process fluid temperature to lower it below ambient temperature to use ambient heat as the source, then processes the fluid to elevate the fluid above ambient temperature to us the ambient as the sink.
