Cars that Run on Cow Power?

(PhysOrg.com) -- Race cars have long provided a testing ground for driving technology that we eventually see in passenger cars on the road. To this end, an engineering team in Lancashire, England, is hoping to give cow power a place in mass-produced consumer automobiles by creating a race car that runs on cow manure. Yep, there are hopes that by processing cow waste and using it to fuel cars, it can reduce the impact of two things that contribute to global warming.
