Not the "few hours" figure (that might be true, though I would estimate more like a full day ?) but rather that's it's any good for crowding around. Hold a smore over that thing and nothing will happen. Now if you want to shove that smore deep into the center of the compost pile, that ought to work, if a little slowly. Recommend you wrap it in foil first.
Surely there's sufficient expertise within this group to make our own wind generators, pedal-power generators, and solar thermal sources of electricity, and make them all out of trash even. I feel like I've said so a thousand times though, in a hundred different contexts to a wide variety of people. I don't want to be annoying, and I've gotten bored with suggesting such. But this time I'm not the proverbial canary. I'm living large downtown with my grid power.
