Nice! I'll keep an eye out for the right sized stainless pots. I was also thinking of riveting instead of screwing the top. I also saw someone (can't seem to find it again though) use the thermoelectric effect of a peltier to run the blower without a battery. Though you'd probably still need an external power source for the first few mins so the pot can get hot enough.

@billysgeo Rivets would work great. Google "Biolite camp stove". They custom built their fans in both stoves so the TEG module can power them right off the bat. They can also charge cell phones etc. off the module. TEG modules are the power generating kind. TEC modules from Coleman coolers etc. don't have the power to run computer fans. Been there done that. Biolite's two models (gasifier and rocket stove) are great. I like the small gasifier camp stove better. Well worth the cash.

@RBEglobal That's a pretty clever design. Having the cooling fins in the path of the air intake. But why couldn't you adapt the same idea in your own design? Perhaps using a couple of those TEG peltiers I found on eBay. Can't post the link, just do a search for "HIGH TEMP THERMOELECTRIC"

@billysgeo Well, time and effort mainly. A 12v car battery will run a computer fan for almost a week straight. Even my smallest battery packs run the stove for 8 hours.

I've got solar panels so no need to engineer a TEG solution. ;) As it went, I spent about a month playing with gasifier combinations to get it right. I leave it up to others to do the TEG addon for my stove. My .PDF build instructions are really clear to follow.

What if I were wanting to /collect/ the gas rather than burn it at the point of production?

[RBEglobal]

@earlye Google "GEK Jim Mason". His Imbert style design would lend itself to that. Collecting might not be a good idea though.

Very tough to safely collect/pressurize flammable gases

thoose little screws You used to made this thing we call "niggers" in Poland ;)

[billysgeo]

I might take you up on that. As soon as I make some time I'll look into the TEG powered woodgas stove!

@567sniper Everywhere. Home Depot, Lowes, Hardware and Farm stores.

@billysgeo You can run the fan down to an extent. Each size stove is efficient only at specific fan speeds. Too low and it's an inefficient burn.

I built this big one to heat a 30 gal. hot water heater. It can do that in an hour and 30 mins. 150 degrees in the tank...while the outside temp was 30 deg.

Plus, the pots I used were sized perfect. No caulk or bullcrap needed. This way others can build the stove exactly. Just buy the same models from a restaurant supply store.

[billysgeo]

mmm... Couldn't you dial down the heat? Run the fan slower (@ 9V) for one thing. And/or use half the pellets. Or even make a slightly smaller version...?
