  • I looked to this 'Dish Stirling - CSP - Technology in Transition' and I was surprised that they did not have any unit in the UK.
    Is that because of cost or political climate?

  15. 15. InfiniaThe PowerDishs free-piston Stirling engine is a proprietary technologydeveloped and manufactured by Infinia Corporation.The engine is a hermetically sealed system that does not require lubrication, hasno touching parts and no wear and tear. Each PowerDish has a service life that exceeds 25 years. Once the engine issealed – engine designed to run for 25 years without any maintenance. Becauseof its design characteristics, Infinias engine is proving to have lower O&M coststhan kinematic Stirling engines.Currently used by NASA, the Department of Energy and other commercialorganizations, Infinias Striling engine technology has nearly 1,000,000 operatinghours, the highest of all Stirling engine manufacturers.
