Flush your Toilet for Electricity

At San Francisco's Cleantech Forum, a conference of investors and innovators focused on the green technology business, a boatload of early stage startups seek to carve off a slice of the billions of dollars venture capitalists are investing in green tech. One participant, Leviathan Energy, based in Los Angeles and Israel, has created a turbine that would create power from the downward flow in municipal water and sewer systems. In other words, whenever you flush, you'd be helping generate electricity.
