Density engines and methods capable of efficient use of low temperature heat sources for electrical power generation
Abstract:
Systems and methods to convert low temperature solar thermal or waste heat sources for electric power generation, by integrating available technologies with a unique, efficient combined cycle. The device consists of mobile pods immersed within a thermal sink fluid reservoir. A vapor cycle converts thermal energy to buoyant potential energy by inducing density and volume changes of the mobile pods through discrete phase changes of a refrigerant working fluid. Buoyant potential energy is then converted to electrical power through motion of the entire pod within a thermal sink pressure gradient.
