60 years ago people used charcoal for fuel. There are a few now that use it and when fuel goes up the numbers will increase. Look up biofuel, wood gas generator, alternative fuels and they look better than $5.00 gas. I got 200 gallons of french fry oil for my bulldozer this summer.

Be sure not to burn up the fuel pump. Mercedes voids the warranty on their diesel engines if you use (Most all) biodiesel fuels. Not enough sulfur to help lube the pump.
