Land, Shelf and Floating Sites
OTEC has the potential to produce gigawatts of electrical power, and in conjunction with electrolysis, could produce enough hydrogen to completely replace all projected global fossil fuel consumption. Reducing costs remains an unsolved challenge, however. OTEC plants require a long, large diameter intake pipe, which is submerged a kilometer or more into the ocean's depths, to bring cold water to the surface.

Famous quotes containing the words shelf and/or floating:
“Give him the darkest inch your shelf allows,
Hide him in lonely garrets, if you will,—
But his hard, human pulse is throbbing still
With the sure strength that fearless truth endows.”
—Edwin Arlington Robinson (1869–1935)
“Writing prejudicial, off-putting reviews is a precise exercise in applied black magic. The reviewer can draw free- floating disagreeable associations to a book by implying that the book is completely unimportant without saying exactly why, and carefully avoiding any clear images that could capture the reader’s full attention.”
—William Burroughs (b. 1914)
