Waterless toilet

In developing countries, access to public utilities like running water and sewer systems are often not available. The lack of those resources leads to unsanitary conditions that can put people’s lives at risk. Researchers at Cranfield University hope to put an end to that with the waterless Nano Membrane Toilet. The design has so much potential to change lives that it’s been backed by the Bill and Melinda Gates Foundation.

Great idea but how is it powered? A crank? Those liquid filters… how long do they last and who comes around to change them? It would be nice if this worked in reality.
