The world needs a new source of energy; one that is continuous, plentiful, inexpensive, safe and unspillable

homemade gasifier uses wood pellets to run generator

Gasifier uses wood pellets to create flammable mixture that a generator can run on without gasoline. This video shows how it was constructed, how it works, and how to use it from start to finish. Great project for anyone looking for alternative energy or wanting to live off the grid. Just for some clarification — I mention a rheostat that I ordered; I ordered a 25w 20 ohm rheostat. That rheostat will effectively give me the control to adjust the voltage to the blower motor from 12v down to nearly 0v (I think… I’m not an electrical engineer).

Excellent and thanks for sharing, I’ writing from Spain, my father who was born in 1913, was a cars mechanic, and he explained me that after the spanish civil war (1936 – 1939), Spain’s lack of petrol moved many mechanics like my father, to self build wood or coal gasifiers, really very similar to yours, (Spanish called “gasógenos”), they were supported at the back of the car with iron rods welded to the chassis, and he runned thousands of miles (several times across the whole Spain) with different cars, Peugeot, Citröen, Fiat, Ford, and a very rare 1920 Maxwell, with which I learn to drive when I was a child.

I’ve seen a few gasifiers on the internet but this one has to be close to being the best yet. Well explained and given me enough of a push to consider building one like it.

Actually shared your video and the FEMA plans with several families in the Florida panhandle in the days following Micheal. I was there from day 1 to day 200 with the USACE BluRoof project. With some areas there being without power for up to 3 months after the storm, gas and diesel in very limited supply (for a variety of reasons), and trees piled up everywhere, those wood gasifer systems we cobbled together were life savers. Your video just came back up in my feed and I realized I had not thanked you.

I wonder if anyone has considered running a heat exchanger between the secondary tank. This would significantly increase the energy density of the vapor as well as give you a controlled source of heat for whatever you need. It could be an air to air run by the already installed 12v air pump or air to water to heat radiant flooring in a workshop or house.

Hey JR fantastic build. One suggestion on temperatures, the hotter you can get your pyrolysis zone the cleaner the gas will be (less Tar) but right after that you want it to get as cold as possible so the gas condenses better. On mine I attached an old radiator and added a bubbler filter full of marbles (the ultimate tar remover). Works like a charm with my inverter generator.
