Abstract:
1. A Rankine engine with efficient heat exchange system, comprising: a vapor phase change engine connected to vehicle propulsion means; an energy storage heat exchanger; an energy source proximate the heat exchanger, wherein the energy source includes a waveguide network connected to the energy source; a high operating temperature slurry capable of rapid heating under electromagnetic energy exposure and being capable of retaining the high temperature for a substantial duration, whereby the waveguide network guides energy from the energy source to the slurry; means for circulating the slurry in a closed loop within the heat exchanger; a working fluid; means for circulating the working fluid through the heat exchanger to pick up sufficient heat content from the slurry in order to change phase to a high pressure vapor/steam; and means for directing the high pressure vapor/steam to an inlet of the engine in order to operate the engine; whereby a vehicle can be propelled under vapor/steam power from stored heat energy in the slurry until the slurry temperature cools down to a temperature ineffective to cause the work fluid to vaporize.
