Marnoch Engine Performance for Multiple Pressure Vessel Configurations
A new type of heat recovery and thermal conversion process is analyzed that produces electricity by recovering thermal energy over a wide range of temperature differences, including relatively small ones. The process induces fluid motion and drives a piston assembly connected to an electric generator. Temperature differences as low as 15oC produce useful power from the process. The performance can be enhanced through solar energy input, which would provide temperatures upward of 90oC at the collector side and increase the Carnot efficiency of the process significantly.
