Efficient rocket stove combined with thermo-electric power

OK. This is genuinely cool appropriate technology.


What I can't find is how much electrical energy it can generate. Typical USB port is 5v*0.5A = 2.5W

And yes, I'm fascinated by this because I've built myself a primitive rocket stove in my wood from bricks. Biggest problem is keeping a plentiful supply of dry firewood of the right size. When it gets damp it's a full time job getting it lit and then keeping the fire going. When it was properly dry in the summer, I got it down to one match, plus silver birch bark and then about 10 minutes to boil 1.5l of water for a brew up.

Music in the wood is currently a M/C battery powered amp and some 8" PA speakers. Two 12v-9AHr batteries lasts us for about 16 hours of UK bass. I don't think the thermo-electric bits in the stove are goig to be able to cope with that, but who knows. Maybe.
