I do really enjoy the ideas that have come out of the tiny house theme. I don't like the politics it brings out[1]. One of the on going issues is sanitation (Bill Gate's efforts not withstanding), can you provide sanitation in a reliable and difficult to screw up way?

In my notebook I sketched out a possible windmill / pump idea that would pump water to a reservoir which, when full would 'flush' for all of the commodes it served. Challenges are odors and blockages, and a reliable sluice system.

And what would it be like if you let people cook with fire in their space? (lots of small spaces in Brazil and India with simple three stone type cookfires. Is it possible to accommodate something like that without creating an undue fire risk?
