Abstract
In one embodiment, a vortex tube has a gas inlet port, a cold gas outlet port and a hot gas outlet port. A thermoelectric potential generator having hot gas inlet port coupled to the hot gas outlet port of the vortex tube, a cold gas inlet port coupled to the cold gas outlet port of the vortex tube, and a thermoelectric element coupled in heat conducting relationship between the cold gas inlet port and the hot gas inlet port to promote the flow of heat/cold through the thermoelectric element from the hot gas flowing into the hot gas inlet port to the cold gas flowing through the cold gas inlet port. In another, a compressed gas source, a thermoelectric element having first and second sides, and an expansion nozzle are coupled in series. The expansion nozzle is coupled between the compressed gas source and the first side. The thermoelectric element includes an electrical output port.
