PwrCor, Inc. announces a significant technology breakthrough that exceeds cycle efficiencies of conventional power cycles. The advancements afford a substantial increase of the potential maximum cycle efficiency of PwrCor’s proprietary power cycle while also realizing higher actual operating efficiency with its latest engine design. The design enhancements are expected to reduce the overall cost per kW output of the PwrCor engine, and will have little impact to the size of the engine, resulting in significantly greater power output within the same general footprint. The new design enhancements are scientifically important and have significant practical implications. There is a thermodynamic limit on the efficiency of an engine, known as Carnot efficiency. These advances allow the projected efficiency of the PwrCor engine to achieve about a one-third improvement, bringing the engine to between 72% and 85% of the thermodynamic limit, depending upon operating conditions. This represents an unprecedented level as compared to other technologies. The practical implication is that the power output of PwrCor’s technology should be able to increase by the same one-third " with no change in input. This is a very significant development.
