Switch to an old diesel like my Mercedes Benz 300D and use recycled restaurant vegetable oil to run your car at about $1 a gallon. http://www.theautochannel.com/news/2007/03/12/040094.html
Great for onesy-twosy stuff, but there isn’t enough to run 5% (probably <2%) of our motor transport, so it’s pretty much just a distraction.
