Ninadecaramelo asked:


I live in Phoenix, Arizona. Do you know of anyone who can convert my truck to biodiesel, and what do you need to do to convert a truck to biodiesel? I want to keep using my truck in an environmentally sound way, and I want to make a stand against using oil by not buying gasoline anymore!

alex asked:


how much does it cost to produce ethanol and biodiesel and any other alternative fuels that you can think of compared to gasoline?
