Although you certainly have a massive amount of water moving in the oceans, I don't think it is moving at a high enough speed. Hence, though you have a huge amount of energy there in the ocean, it is spread out over too vast an area to make harnessing it in an efficient manner possible.
On the other hand I am absolutely unqualified to make any kind of judement in this area so I could be completely wrong!  |
Well, I'm not qualified to declare that you are completely wrong but let me defend
fuzyfuser's idea a bit.
I'm not saying that there aren't problems with "
seamills" (well, you come up with a better term!) but I don't think the slow ocean currents is one of them.
It doesn't matter if the windmills turn slowly because you can simply use a bunch of gears to turn slow motion into fast motion for generating electricity. The only problem is if the fans turn with enough force and they just might, considering how dense water is.
By the way, where are the Niagra turbines? Are they at the top of the falls or the bottom?
