Volkswagen should also take note – Bristol, UK-based waste treatment company, Geneco has converted a cute VW Bug into a bio-fuel guzzling machine. Using the solid waste from 70 homes, the Bio-Bug could drive 10,000 miles a year with a fuel-efficient of 5.3 miles per cubic meters f the bio-gas. The Bug can also run on traditional gasoline as well. The Bio-Bug, unlike other bio-fueled prototypes, runs more cleanly, with a comparative performance to petroleum-based fuels.
Big companies are also recognizing the power of poop. Hewlett Packard, Microsoft and Google have investigated partnering with American dairy farmers, considering the possibility of creating poop-powered data centers. The initial equipment investment may be what is holding them back, but the renewable power is great, with the average cow pooping enough power to light a 100 watt lightbulb.
