Theres a reson the us used pens instead of pencils.
Its because when you write with pencils, small shards of (conductive) grafite fall off.
These then go around and around and around the space craft, until they find some rather nice control to short out..... (Pencils in space == Bad karma)
If you were to have a straight pipe, which is insulated, then remove the insulation for the top part of the pipe, would it pump the water upwords?
Because warm water rises, as the cold water heats up to the warmer surrounding ocean water, it expands and rises, pushing up more of the cold water with it.
Maybe shove some fins on it, to get it to exchange the heat faster.
Not for power, but for aquaculture. (the water is very nutrient-ritch).
You could have massive fish-farms pretty cheaply for all that. (just convert a lake which is close to the coast into a fishery).
