We design and manufacture a patented acoustic engine that dramatically reduce costs of electricity production in hot countries, and produces cooling from waste heat and exhaust gas for any purpose, : the principle is to use waste heat recovered as fuel to generate high potential acoustic waves that can produce cooling, electricity or mechanical power for stationary or on bord applications
