Claims

1. A HEAT ENGINE COMPRISING A CIRCULATING SYSTEM CONTAINING A WORKING FLUID, THE SYSTEM INCLUDING:

PRESSURIZING MEANS TO RAISE THE PRESSURE OF SAID FLUID IN LIQUID PHASE FROM A LOW CYCLE PRESSURE TO A HIGH PRESSURE;

MEANS TO ADD HEAT TO SAID FLUID SUBSTANTIALLY AT SAID HIGH CYCLE PRESSURE TO RAISE IT TO ITS HIGH CYCLE TEMPERATURE SUBSTANTIALLY ABOVE ITS CRITICAL TEMPERATURE;

MEANS TO EXPAND SAID FLUID THROUGH AN ENERGY CONVERTER TO DO USEFUL WORK;

AND MEANS TO COOL SAID FLUID SUBSTANTIALLY BELOW ITS CRITICAL PRESSURE TO A TEMPERATURE SUBSTANTIALLY BELOW ITS CRITICAL TEMPERATURE TO RENDER IT COMPLETELY LIQUID FOR ENTRAINMENT BY SAID PRESSURIZING MEANS;

THE LOW CYCLE PRESSURE IN SAID SYSTEM BEING SUBSTANTIALLY ABOVE THE CRITICAL PRESSURE OF SAID FLUID.
