Bill Gates on Quest to Reinvent the Toilet

"Toilets are extremely important for public health and, when you think of it, even human dignity," Gates said.

"The flush toilets we use in the wealthy world are irrelevant, impractical and impossible for 40 per cent of the global population, because they often don't have access to water, and sewers, electricity, and sewage treatment systems."

Not glorious, but really cool.
