Cool Energy finishes third engine

BOULDER – Cool Energy Inc. has completed its third Stirling Engine platform that converts low-temperature heat into electricity.

Boulder-based Cool Energy expects the new engine, called the SolarHeart Engine, will generate about 1.5 kilowatts of power. The engine, which will be integrated into a solar thermal system for homes and businesses, cycles gas between a hot and cold area to create energy that’s then turned into heat or electricity.

“After our engineers finished assembly of the engine, it ran upon first activation,” Sam Weaver, Cool Energy’s president and chief executive officer, said in a statement.

The unit could reduce energy bills by as much as 75 percent, according to the company.
