Composting toilets have been around for awhile as have incinerator toilets, but these are are taken to the next level in terms of sanitation, hygiene and water/electricity usage.

New toilet technology after 150 years of waste

(AP) — These aren't your typical loos. One uses microwave energy to transform human waste into electricity. Another captures urine and uses it for flushing. And still another turns excrement into charcoal.

They are part of a Bill & Melinda Gates Foundation competition to reinvent the toilet for the 2.6 billion people around the world who don't have access to modern sanitation.

Scientists from around the world have taken up the challenge and the foundation planned to announced Tuesday which projects would be getting more money to take their ideas from the lab to cities.

There, local entrepreneurs will use the new technology to turn pollution into cash.

To pass the foundation's threshold for the world's next toilet, it must operate without water, electricity or a septic system, not discharge pollutants, preferably capture energy or other resources and operate at a cost of 5 cents a day.

The United Nations estimates disease caused by unsafe sanitation results in about half the hospitalizations in the developing world. About 1.5 million children die each year from diarrheal disease.
Scientists believe most of these deaths could be prevented with proper sanitation, along with safe drinking water and improved hygiene.

The foundation expects to field test its first prototypes within the next three years.

Nice!  Sounds like something that could be used worldwide.

A solar powered toilet that breaks down water and human waste into hydrogen gas for use in fuel cells has won first prize in a competition for next-generation toilets to improve sanitation in the developing world.The California Institute of Technology in the US received the $100,000 (£64,000) first prize for its design. Loughborough University in the UK took the $60,000 second prize for a toilet that produces biological charcoal, minerals and clean water, and Canada’s University of Toronto came third, winning $40,000 for a toilet that sanitises faeces and urine, and recovers resources and clean water.The winners took part in a Reinvent the Toilet challenge set by the Bill and Melinda Gates Foundation, which asked designers to break with a sanitation model that has changed little since it was developed by Alexander Cummings more than 200 years ago. It is a model that depends on piped water, sewer or electrical connections that poor countries can ill afford.The Raw Story
