The guys over at Hidden Homesteads are converting propane gensets to run on biogas, so they can run a vehicle on wood, or produce electricity from wood -- clean enough to vent the exhaust into the home to capture all the heat produced.
Doug Brethower provided us with the following photos and descriptions:
: Learned a lot of lessons converting this vehicle engine platform to dual fuel gasoline/woodgas. The first revelation was that the engine ran as soon as we "put the smoke" to it. Not good, but the engine ran. Amazing to me that a computer controlled engine does that.
: Pictured is smoke that runs the engine. Gasifier is being "backburned" for show. In operation this is our fuel, so we don't waste a puff of it. When running down the road, there are no external visible signs the engine is powered by smoke. The emissions are cleaner than when running on gasoline.
: After some tweaking, AFAIK, this is the best OBD-II implementation in existence.
: It runs as good on wood as it did on gasoline when we got it, and quite a bit better on gasoline, thanks to some performance tweaking.
: Long story short, woodgas works just fine for those who know how to use it. Knowing how to use it is not difficult, but it takes time and hands-on experience. You can't teach someone to ride a bicycle with words and pics. They have to get on and push the pedals, fall off a few times, skin a few knees. It takes time. But once learned, it so intuitively simple that it becomes baffling why it is so hard for other people to understand it. Most people don't even understand the need for it. That is why it such a pleasure to be on your show ~)

: Systems are specifically tailored to local low value biomass.
: The "gas producer" can be as simple as this sawdust gasifier, if sawdust is locally available.:
: Approximate dimensions are 30" W x 40" H x 12" deep. It weighs about 100 pounds.
: To operate, pull some suction with a shop vac (or hand crank forge blower), light it, in a few minutes with shop vac, 15 minutes with forge blower, it is making engine grade gas. Re-fill it occasionally for continuous operation. No need to shut off engine to re-fill.
: This has powered a 10kw genset. The 15kw genset uses the same engine, would just require more frequent re-fills under load. A hopper on top with an simple auger allows continuous operation. A circular sawmill produces approximately twice as much sawdust as needed to power the sawmill. Not from theory, from actual real world experience. The first operating system was about 1980. The sawmill now runs on diesel made from tire rubber, with sawdust powering the conversion, but that is another show ~)
: Propane genset is trailer mounted, not chipped.
: If sawdust is not readily available, a system patterned after the Wayne Keith gasifier is used. Wayne Keith driveonwood.com has a design that is very fuel tolerant, and can be sized to fit in the back of a truck.
: When used for stationary power, a constant load and RPM, the WK system works even better than it does on a truck. Size and weight limitations are not the concern they are on a vehicle. Bigger filters and condensate tanks are used to increase time between regular maintenance.
: Collectively we are barely scratching the surface of the awesome power of biomass, natures original solar storage design.
: Individually, there are those who make gasification work fantastically well for themselves. Engaging more people to learn how to do for themselves and their communities is my vision for building a better future, freed from the shackles of the "fossil fuel pharaohs".
: Fifty percent more heat per stick of wood, emissions clean enough to run unvented indoors, creating a valuable co-product biochar, biomass gasification is a win-win-win for Energy, Environment, and local Economies.
: Appreciate you doing your part, plus a little more. People engaging people, "each one reach one, each one teach one" is creating the "great change", the better world we know can be.
: I had the good fortune recently to partner with James White and Chris Allen in a venture termed Hidden Homesteads. Together we are actively implementing an innovative whole systems approach for living better. The whole system design incorporates the latest technologies such as biomass gasification, with infallible design patterns proven throughout the ages.
: Working harmoniously with nature and neighbors is a paradigm shift from the relatively recent total domination strategy that is reaching it's inevitable conclusion, crumbling to pieces.
: Educational outreach is the first leg of our efforts at Hidden Homesteads, finding the eyes that are open, encouraging and aiding fellow visionaries toward great works.
