Abstract: A Novel thermodynamic cycle known as the ‘Hybrid Power Cycle’ is proposed consisting of a power cycle and a refrigeration cycle in a partial form, using fixed amounts of the same working-fluid in closed cycles. The vapor in the partial refrigeration cycle undergoes a polytropic compression with the rejected heat removed by the compressed liquid in the partial power cycle before both are combined at same pressure prior to entering a heat exchanger to absorb ambient heat. When the temperature reaches the desired level, they undergo turbo-expansion yielding a minimum external achievable work of 60.63KJ/kg of liquid nitrogen (LN2). A novel binary-hybrid cycle was also invented to increase the external work-output to 77.79KJ/kg (LN2). This technology can be used to generate clean electrical and mechanical power including transportation without any fuel at a low cost, using only ambient heat with zero environmental pollution and zero global warming potential.
