Tim,
What came to mind upon hearing about the 'pipes in the sea' was the NOAA
ill-advised OTEC program of 20+ years ago or so. OTEC = Ocean Thermal
Energy Conversion.
This was long ago and I was only peripherally involved so memory may be
somewhat degraded. The idea was to suspend 30 foot diameter pipes 300
feet long from the ocean surface. Somehow - the exact details escape me
- the temperature gradient between the surface and the deep end of the
pipe would be used to generate a current (water flow) which would drive
some sort of generator. I believe some scale models were built and I am
sure that if you Googled OTEC you would find all sorts of stuff and, I
believe, some of it recent.
One of the major problems, as you can imagine, is how do you get the
energy you generate to shore? A long power cord? Use the energy to
separate water into H and O and ship the H to shore?
