    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.

    Another possibility, depending on the space you have- methane digester.

    Methane gas has lower heat value than propane or natural gas, but you can make your own from manure, can use it at low pressure to run a fixed engine or a burner, can compress it into a cylinder for transport.

    Google Ram Bux Singh, Gobar, biogas, methane and Mother Earth News for some of the backstory. Nice part is the waste product from a methane disgester is DAMN good fertizer.

    I just downloaded gasifier plans so i can see what ill need to build one. The one im looking at building has an outer shell made of a couple of 55 gallon drums with a steel combustion chamber. The reason im thinking of a gasifier over a methane digester is because wood would be easier for me to come by than livestock manure.

    Just be careful. The gasifier is a potential bomb.

    May I suggest you take a look at Mother Earth News plans for their wood gasifer. The plans are about 40 years old. They ran a pickup across the country on wood scraps they could find. They also built one to run genset.

    They can be low tech and low cost if you are a good scronger. They used an old hot water tank as ther main body as I remember.

    Good luck.

    Gasifiers are really good, and were in usage throughout WWII as patroleum was being cut off from the Germans. The probem with gasifiers is that poor craftsmanship caused Carbon Monoxide leakage, killing people. Don't run indoors.

    Yeah thats one reason i plan on running it in my barn, its about 50 feet from the house. Far enough away i dont get the fumes and the noise of the running genny but close enough a single ext. cord will reach the house.

    I need something somewhat simple because i dont have a cnc machine and/or a high tech machine shop. I can get most or all of the parts local from junk yards or junk laying around my in laws farm.

    FEMA has the plans online if you haven't seen them yet. You can google "Emergency wood gasifier". I'm an engineering major and was actually planning on building one as a school project (doesn't seem likely right now). Good luck, and if you do undertake this design, post pictures so we can learn from you.
