[Stoves] Cooking on top of a pressure cooker containing heated scraps, fat and grease

[Crispin Pemberton-Pigott]

Dear Friends

This is so off-the-wall that I had to look twice:

These guys are treating 1,500,000 cubic metres of waste water a day. The
accumulated solids are pressure cooked, which starts a breakdown of the
gunk, which generates heat, which makes steam, which spins generators, which
earns $10m annually in electricity.

If a pressure cooker of wastes can be induced to self-destruct, the pot
itself could become a cooking stove. Huh.

Instead of making biogas to burn, just create heat directly when you want it
decomposing the dung (or other inputs) in a container with a flat top
surface.
