    The world's most efficient Stirling engine

    At the reference facility in Upington, South Africa, a net efficiency of 32% is recorded. No competing technology has ever demonstrated a conversion rate from solar to electricity of grid quality that high, so with that, Ripasso Energy can claim the unofficial world-record. In January 2015, an independent test will be carried out by IT Power, which will show that the efficiency of the Ripasso Stirling engine is in fact 33 %.
