10 Innovations in Hydropower

Inventor Rick Dickson was inspired to create his hydrosphere after reading about naturalist and explorer Dr. Charles William Beebe (pictured here), who plumbed the depths of the ocean in a bathysphere back in the 1930s. Keystone/Getty Images

It looks good on paper, but inventor Rick Dickson says his idea can work when put to the test. Dickson is talking about a hydroelectric generator that takes advantage of the immense pressure differentials in the deep water of lakes or oceans. He calls it a hydrosphere and believes it can generate up to 500 megawatts of continuous renewable energy [source: Scoop].

Although he has yet to build a prototype or secure a patent, Dickson's hydrosphere is a type of enclosed, cylindrical hydroelectric dam that works off the varying pressure of ocean or lake water [source: Scoop].
