I'm thinking that at least a few of you probably have built working gasifiers, and in the process you must have done plenty of research first. I've been looking at building one for a few years now in an on-again, off-again kind of approach, but i think i really a going to do it now. the one last thing i am looking for before i start is a good sounding board - ideally a forum. the problem is that i haven't found a place like what i want yet. i have seen a ton of sites with people's builds and lots of design information, but there are always hidden things that they did that you can't see. hopefully i can ind people willing to share the details.

i found one alternative energy forum that literally had one post in the gasifier section, made over a year ago. i've also found others that seem to be mostly built around the community that have bought the gasifier kits they sell. what i'm looking for is basically a forum with an open-source attitude with people who have built their own units from scratch. i know that a build is likely to involve some tweaking and possibly rebuilding after the fact, but i figure that if i can find a group of people who are already in the know, they might be able to tell me some things i should not do, or should do differently.

as a bit of background, i'm planning on building a gasifier to run a 16hp 2 cylinder engine, powering a belt drive generator head. i'm not looking at this as a necessary item that i'm going to depend on, though it would be nice if it turned out to be that good and reliable. i was the kid who tore apart every toy he had, just to see how it worked. i've always been fascinated by anything mechanical, and i've spent a lot of my life building and working on things, so this is really just natural progression. it's also a matter of availability - i have a 16hp wisconsin-robin engine, a few good air compressor tanks that were donated due compressor failure, a good hot air furnace heat exchanger, and even a 4kw belt drive generator head. though, if i can get this to work, i'll likely buy a slightly bigger generator head.

Wow, sounds like an I interesting project. Sorry I can't add any info, the only wood gasification stove I saw was a super efficient wood stove "boiler" (but not technically) .
Do you plan on storing large quantities of the gas to use as needed?

Go to Mother Earth News. They are good at researching and investigating the pros and cons. You can find a lot of info there.

Yahoo has a woodgas forum. I believe it's called exactly that, "Woodgas". Communication between posters is relatively easy.

Good, hope you find a lot of info. Just don't forget Mother Earth News.

Wouldn't a steam engine be more efficient? Turn heat to power rather than use heat to manufacture fuel to provide power?

no idea to be honest. i'm not familiar with what it would take to fabricate a steam engine of a sufficient size to turn a generator. crude but functional gasifiers can be built pretty easily out of scrap, and that is probably one of the more attractive features for many when designing these as a backup power source. my approach is adding an extra layer in, since i am building a device to extract gas from wood to power an engine to turn a generator.

gasifiers initially became popular because of the shortage of fuel to power existing vehicles, tractors, and other equipment. there is still a use for them in under developed areas of the world where fuels aren't easily available. in this part of the world we never saw the shortage during ww2 that they did in europe, where gasifier use became common to power your vehicle.

my interest is purely hobby - i've already got a hydraulic feed pto chipper to generate a limitless supply of fuel, lots of surplus tanks and scrap metal that is just screaming gasifier, along with a wisconsin twin that i haven't been able to find a use for. if it will all work when i'm done, there's a 7.2kw harbor freight generator head for $300 with a lot of good reviews that will mate to it and produce a neat and fun project that actually could be useful.

this is all a precursor actually. one other "hobby" i have involves somewhat a uncommon older brand of european automobile, and i'd just love to build a gasifier to power one of them. some people like to sit in their chair and watch football, but i'd rather exercise my mind and create something.
