ABSTRACT:
This disclosure is related to electrical generators which utilize heating and cooling of separate points in a closed circuit ferrofluid system to generate electrical power directly from heat energy. The characteristic of ferrofluids to experience rapid change in their magnetic properties with temperature is utilized by placing a magnet around the circuit to create a self-pumping action of the ferrofluid through a solenoid to generate electric power.
