About 2.6 billion people worldwide do not have access to a sanitary toilet. To fix this, the Bill and Melinda Gates Foundation awarded eight grants last year to scientists and engineers to invent a toilet that could function without piped water, a sewer system or outside electricity—and would cost less than 5 cents a day to operate. With the funding, scientists are working on using processes such as evaporation, combustion, pyrolysis and anaerobic digestion to break down waste in toilets into three essential resources: water, fertilizer and fuel.

The 6th annual Invention Awards are here, from an inflatable tourniquet to a better lobster trap to spring-loaded hocket skates. This issue is all about the celebration of invention.
Plus: Making synthetic biology breakthroughs in a garage, building a constantly-moving ping-pong table, and a ridiculously overpowered barbecue.
Saw similar concepts from the TED projects. I think combining this with the Popci peepoo article bag putting them out like sausage links sealed in a bag until it safely degrades the plastic to release safely digested compost. Smell is the biggest feature preventing appeal. Negative air pressure is obvious, but my favorite concept is a cool plasma barrier during defecation.
This is such a waste of money. Aside from the fuel aspect a simple composting toilet would fill all these criteria. I have one in my remote cabin and it works great. When used correctly it is sanitary, there is no smell and the end product makes great fertilizer.
