Back To The Future: A Food Powered Car

The "Rinspeed Advantige Rone" concept car is less than one meter high, has LCD displays instead of mirrors, a very neat design and can reach speeds up to 205 km/h. But the most unusual are the following features: tilting cockpit (you feel like riding a motorbike) and fuel - kitchen and garden waste." [I]t can either run on compressed natural gas or 'Kompogas'. Kompogas is made by fermenting organic kitchen and garden waste. Developed in Switzerland, Kompogas is CO2 neutral, and therefore does not contribute to global warming. ...it accelerates from 0-100 km/h in under six seconds, nearly as fast as a gas-guzzling Corvette (with nearly three times more horsepower!). Top speed is a police-evading 205 km/h, the same as a Mazda Miata." [Halfway down the page is another interesting article on the ULTra -- an "automatically controlled personal taxi system running on its own guideway network" developed by the University of Bristol.]
