This sounds like a variation on Christiaan Huygens' gunpowder engine. Biscuittin (talk) 18:48, 9 October 2009 (UTC)


Does the "concept engine" have any practical applications? I suppose it might compete with a hot air engine where only a small power output is required and thermal efficiency is not important. Biscuittin (talk) 20:42, 9 October 2009 (UTC)


I believe invented by one Henry Wood in 1758. Can't find a definitive reference though. (talk) 18:09, 24 October 2011 (UTC)
