ABSTRACT:
A closed cycle energy conversion system adaptable for use with, inter alia, solar collectors and other sources of available heat for increasing the temperature of a circulating fluid to a super heated condition and employing a substantially vertically positioned gas expander column comprising an endless arrangement of cups journaled for movement in a closed path within a liquid medium in the column for trapping the super heated fluid when flashed into a gas inside a succession of the cups inverted at the bottom of the column and displacing at least a part of the liquid in the cups, thereby providing a buoyancy force on the cups causing them to rise in the column exerting a rotating force on the endless arrangement of cups. The trapped gas is released at the top of the liquid in the column to be condensed, pressurized and recirculated to solar collectors and/or other sources of heat for reuse in the system.
