A hermetic Rankine cycle in a sealed casing powers an internal centrifugal condensate pump with an internal vapor turbine during forced convective heat transfer between a heat source and a heat sink. No work is imported into the cycle during operation. A centrifugal pumping disk shears the working fluid against a heating surface, sweeping evolving vapor into radial vortices which provide sink flow conduits to a vapor space at the center of the cylindrical turbine. Convective mass flow through the vapor space to the condensing end of the casing spins the turbine and the centrifugal pumping disk which is connected to it. Vapor is continuously swept from the heating surface, so bubbles do not form and superheat while blocking heat flux into liquid working fluid. Vapor is sucked through the radial vortices into the central vapor space and into the condensing end of the casing along the low pressure gradients in vortex cores established by cooling power. A high heat flux surface is thereby thermally connected to a conventional heat sink having high cooling power, for maximal heat extraction at data centers or other heat sources. Vapor vortices organize counterflow of vapor and condensate in a continuous mass flow cycle, and extract work from heat. Organic working fluids can be used in the casing to make even low temperature waste heat a power source.
