The present invention includes systems and methods to recover heat from a lower quality heat source and convert that heat represented by its temperature differential range into a different form of extractable energy. In various illustrative examples, the system may include a heat recovery heat exchanger, a conventional counter-flow vortex tube, a power producing turbine, a condenser heat exchanger, and a liquid circulating pump. The system further comprises a condenser heat exchanger that is adapted to receive the turbine exhaust vapor, wherein the temperature of the exhaust vapor is reduced via heat transfer rejecting the waste heat to the surrounding atmosphere at atmospheric temperatures; wherein the compressible working vapor is converted to a saturated liquid and returned to the first heat exchanger by pumping means for further cycling.
