1. Apparatus for generating fluid vapor pressure for the operation of a vapor engine comprising at least three heat sources of variable temperature, a fluid selectively circulated between the heat sources, sensing means for determining the greatest temperature differential between the heat sources, valve means for connecting fluid to any two of the heat sources having the greatest temperature differential to provide a closed cycle system for the transfer of heat from the one source to the other, pumping means for forcing fluid through the system to a heat source, a power transducer connected to a heat source which vaporizes a fluid.
