The design uses propane tanks and they are good for 500cc - 5.0 liter stationary internal combustion engines. Diesel engines can work with up to 75% wood gas/25% diesel. If you want to run bigger V-8 engines and fuel trucks, then use the hearth sizing chart and scale up the rest of the system to match.

With the information in this plan set and some ingenuity on your part, you can: run spark ignited generators -- fuel older vehicles -- gas tractors -- heat greenhouses -- pump well water -- fire up kilns & forges -- make activated charcoal for water purification -- go off grid and much more!

Wood chunks are mandatory because they make the best charcoal. The secret is in the charcoal chemistry. Use a table saw/ band saw to make them. No pellets, no hog fuel, no tires, no garbage, etc. Wood species does matter. Most work, but not all. Pine, fir and oak are good. Cedar is quite oily and cottonwood is too ashy. Test, test, test. The run time depends on how dense your wood is. The base reactor will hold a 40 minute load for initial testing. Add a hopper and get run times of several hours. Run a batch in the morning to charge batteries. Run again in the evening if needed. 24/7 is UNREALISTIC. Design your feed system around your wood type and energy needs.

Inflation has dramatically raised prices of steel and mandates have reduced labor. The below prices have gone up --- Bare bones, expect to spend $1500 - $2000. Using CNC parts, self built, expect to spend $2800 - $3500. Subcontract portions of your build and expect to spend around $5,000. Done for you turn-key, expect to spend $7500 in mild steel, $12,500 - 15000 in stainless. Generator set NOT included.

You generally do not need to store gas. The gas is produced on demand by the suction of your engine or blower motor. You can bag the gas, but it's bulky. You can compress the gas into composite storage tanks or oxygen type tanks (1/4" thick), but don't put wood gas into air compressor tanks (1/8" thick) because the hydrogen can embrittle the metal over time and rupture your tank. Danger! The energy conversion is approximately 2.5 lbs of bone dry chunks into 1 kilowatt/hr of power in a 3600 rpm engine. 3 lbs per kw/hr at 1800 rpm.

A poorly built/ low suction/ improperly tuned gasifier can produce tar. Tar occurs when wood oils aren't completely turned into wood gas and end up in the engine valve stems as creosote. When a gasifier is sized to the correct engine, using the charts in the book, then this isn't a problem. As a new user it is recommended you use an old engine to practice with while you learn the art of being a wood gas operator. Most youtube tinker projects are making oily gas. You get what you pay for.

No, this is a DIY set of plans for educational and personal use only. -- If you become masterful as a wood gasifier builder, operator, designer and engine integrator then you are welcome to design and build your own UNIQUE gasifier system and sell it under your own brand name and liability. Use a name plate to identify yourself as the builder and use warning labels. -- Do not use any elements from the book or the author's name. No knock-offs!, No "business opportunity" seekers. No grant chasers.
