Cool Energy

Using the SolarHeart Engine, a low temperature Stirling Engine

Cool Energy has developed an innovative and pioneering Stirling engine, called the SolarHeart® Engine, that converts low temperature heat energy (100°C to 300°C) into electricity. The initial market application for the SolarHeart engine, due to its potentially rapid payback time, is the recovery of wasted and exhaust heat to produce electricity.

These Waste Heat Recovery settings including commercial and industrial facilities, remote and military generators, and supplemental and backup electrical gensets can all benefit from using the SolarHeart Engine for electricity production. The waste heat recovery scenarios by the SolarHeart Engine offer payback time as low as one year, due to the low cost of the engine and the “free” fuel input.

The SolarHeart Engine captures waste heat that an industrial site, commercial process or power generator is already emitting, and turns it into clean and renewable electricity, recycled thermal energy, or mechanical energy. A valuable approach to improving overall energy and operational efficiency is to harness and reuse the lost or "waste heat" that is intrinsic to all industrial manufacturing and gensets.
