Has anybody here looked into alternative fuels or know anyone who has for running a generator or car/truck? I saw on Doomsday Preppers a guy had a 'gasifier' running an old pickup truck they used around the farm. He said it was also possible to use it to run a generator. Ive also heard of people makin thier own biodeisel. Ive considered building a gasifier and putting in the barn to run a generator for the house for when the power goes down or for a shtf scenario. Just wondering if its really possible and how difficult it would be.
