  • Dual-phase thermal electricity generator
    Patent number: 8484974
    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.

  • Variable orifice valve
    Patent number: 7559485
    Abstract: A variable orifice valve provides a changing orifice dimension based solely upon the temperature or other property of the fluidic medium, such as flow-rate of the fluidic medium passing through the valve, and is actuated via a thermally active wire or flow-rate activated spring, for example, immersed in the fluidic medium.
