Bill Gates’ charitable organization, the Bill & Melinda Gates Foundation, is investing $370 million in the development of toilets that can improve sanitation around the world.
Gates attended the Reinvent the Toilet fair in Seattle, where he looked at designs that included a toilet that used microwave energy to turn poo into electricity, another that turned excrement into charcoal, and a third that used urine for flushing.
A total of 28 designs were shown off at the fair. A $100,000 prize was awarded to a team from the California Institute of Technology. Their design: A solar-powered toilet that generated hydrogen gas and electricity.

Nothing better than looking at a multi-bazillionaire staring down a toilet.
