Kite Turbines
I was actually thinking about an alternative energy source from the sea... it would float on the surface and be like a set of interlinked chains in a fabric with dynamos in them that the simple harmonic motion of the ripples of water constantly could be used to create electricity.<p>Let's suppose out at sea each peak to trough is 60cm and the movement up and down causes the internal dynamo to be driven  by 30cm for each one - you probably need two lines into each one, positive and negative serially and you could get a pretty good average amount of electricity probably.<p>No idea if it would work or the output would be too uneven but there is a lot of sea and it seems a bit easier to build and repair than something that sits statically in the water.
