I'm not up there but I've played w/ wood gas a bit. What are you wanting to do with the gas?..just curious...
A couple cleaned out paint cans and some metal piping is all it takes to make a simple gasifier that'll produce a flame similar to a bunsen burner. It's a good place to start, I think, since you can bang one out in an hour w/ basic tools and it's not a big investment. You can control the gas flow w/ a wet towel around the condenser can and tubing -- it's not too hard to keep a fairly steady flame/temp that way, but it's not quite the same as a knob on burner.
I've been wanting to make one similar to that but a little bigger and more robust so I can install it in our woodstove. The wood box is larger than it needs to be and I think using some of that space to produce gas could be worthwhile, but it'd have to make enough gas to run an RV fridge, or similar.....and I'm not sure if I can do it and still get/afford fire insurance, so I may have to do it in the backyard and make a fancy BBQ pit / outdoor kitchen.
I think that's 2¢ worth...yeah...
