A high pressure thermomechanical cycle using mercury as the working fluid can be made practical at close to theoretical thermodynamic efficiency between a hot shoe temperature of about 1200 K (3000 psia boiler pressure) and 600 K condenser. Means are proposed for utilizing a simple Rankine cycle without superheat, in which liquid droplets are vaporized by radiative heat transfer after being sprayed into the boiler chamber as a mist; and in which vapor wetness is controlled (by addition of further hot mist if need be) prior to expansion in a nozzle; and in which, after expansion, the kinetic energy of both droplet and vapor phases is utilized in a turbine.
