Claim 1
Independent Claim
91 words
A METHOD OF TRANSPORTING THERMAL ENERGY FROM A HEAT SOURCE TO A HEAT RECEIVER WHICH COMPRISES ABSORBING THERMAL ENERGY FROM THE HEAT SOURCE BY SUPERCRITICAL PRESSURE STEAM, PUMPING THE STEAM IN A CONFINED STREAM TO THE HEAT RECEIVER, TRNASFERRING THERMAL ENERGY FROM THE STEAM TO THE HEAT RECEIVER, RETURNING SAID STEAM STREAM TO THE HEAT SOURCE FOR FURTHER HEATING, AND MAINTAINING SAID STEAM ABOVE ITS CRITICAL VALUES OF PRESSURE AND TEMPERATURE THROUGHOUT THE CYCLE, WHEREBY THERE IS A CONTINUOUS TRANSPORT OF THERMAL ENERGY BY A FLUID ALWAYS IN A SINGLE PHASE.
