Kent S Knaebel: Power generating cycle. EcoEnergy I, Mueller and Smith, March 4, 1986: US04573321 (45 worldwide citation)

The present invention is a multi-step process for generating energy from a source heat flow. Such a process comprises passing a heated media having a mixture of a low volatility component and a high volatility component into a phase separator. The vaporous working fluid is withdrawn from the phase s ...
