Hydroelectric power with a flush

What do you envision when you think about hydroelectric power? Large dams? Giant spinning turbines? Toilets?

Yes, toilets. Lucid Energy, a company in Portland, Oregon, is taking clean technology to a new level. They have invented a small turbine that can be placed inside existing water pipes and capture energy from water already flowing under pressure. These turbines can generate up to 50kw of power and can be installed in drinking water or wastewater pipes.
