Abstract
This disclosure relates to a device and system capable of producing electricity by using a temperature gradient and a dual-phase fluid to convert thermal energy into electrical energy. The system relies on a sealed enclosed volume that utilizes a thermal gradient to vaporize and condense a dual-phase fluid. The cycle of the fluid transforming between the two phases is used to turn a turbine to create electricity. The thermal gradient can be enhanced using energy input from the sun.
