Has anybody seen the Channel 4 show with Kevin McCloud building his own little shed in the woods? it was called man made home or something. He looked into producing methane for his consumption on his land (a bit different from drying horse poo, I know, I bet he didn't think of that) - but I thought it could work too.
Of course you'd need a massive tub to put the poo in, and let it ferment long enough, but then you have methane all right. I'm sure it could be connected to any gas kitchen stove.
Little issue is, if there's a leak you might not be able to smell it (commercial gas has some smelly sulphur compound added to make it smell obvious in case of leaks) and that could be dangerous.
Much bigger issue is, apparently the best poo for that is carnivore poo! So the worst, evil foul smelling dog poo, cat poo, even people's would work. Kevin went to collect lion poo for his shed!
Now, who is going to volunteer for poo picking?!?
