A heavy truck moving downhill would cool its exhaust (and ambient air as well) to accumulate the thermal energy. The accumulated energy would boost the truck uphill. > But you're... =A0Nah, nevermind, it's not my job to debunk every dumb ide= a > someone dreams up. =A0Go look up "perpetual motion machine". Kinda online Zorro on a special mission to fight dumb ideas :-) Sorry, no "perpetual motion machine" meant. The compressor is fed by gravity force. The "Telepathy" course should be retaken :-) --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
