Have you ever seen the WhisperGen, from Christchurch, NZ? Seems real enough. http://www.whispergen.com/ 4-cylinder Sterling engine producing 1200W of AC power on natural gas, or 800W of DC power on diesel/kerosene. Up to 8000W of waste heat available for domestic hot water or general heating needs. -- Dave Tweed -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
