Hydrosphere

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.

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].
