It prevents you from holding on to that inefficient Model A forever. On the other hand, it fits like a glove that low speed diesels running on peanut oil, aspirated ethanol and water would have prevented a lot of bad feelings with the sons of the desert sands. I think I will build a high heat semi rankine carbon fiber and balsa wood mag wheel aerobike with a petter diesel running on water and a 200 lb flywheel charging up a redox vanadium battery or some kinda zinc-air thingie, putting the waste heat into seebeck charging, and the flywheel into kinetic-electric, with a penta junction multi layer semi-c photovoltaic roof, with dc motors on the wheels and electronic skid and power control linked to steering. Then put a large switch-scythe on the side to take out them 2050 bulgers doing the green thing on their self propelled yuppie cycles. Just doing my bit for the planet. Yah know, we should be underwater. Fish need a lot less energy to live, need less food, as they are suspended by their medium. Mann found the most efficient diesel electric undersea devices in cousin Rudi's invention .. (Low speed large diesels approach 45% efficiency) but of course they used them for purposes we could not abide. Still an ill wind could blow us back to sustainability. What we need to build is the 4th gen scuba tank that converts water into air so we can live underwater. Have to fix that decomp thing. Maybe shallow water, so we don't have to decomp. I can see it now. Peanut methane ethafuel-aspirated diesels breathing underwater converted air attached to a bathing suit.. browsing hydrazine and plankton off the sea bottom. Whale of a time. We will iron it all out, or we will selected out. No worries. At any rate something has to happen on the seventh day of the seventh month of the 2007th year. EC<:-}
