GET INVOLVED

We are looking for other brave people to join our venture: experts, investors and pilot customers.

LOOPING HEAT TO POWER

The high efficiency of our unique engine is achieved by a method whereby heat energy is recirculated inside the engine. The studies and experiments have shown there's a way to make more compact and cheap, yet efficient heat engines.
