Can we extract energy out of a capacitor in the ocean?

[QUOTE="collinsmark, post: 6105568, member: 114325"] I have a couple of questions which you should ask yourself. 1. Are there any forces on the cylinder of water caused by the electric field in the capacitor? (i.e., besides the force of gravity. Remember, the water is a dielectric.) If so, what effect are these forces going to have on the column of water? 2. I was going to ask about the inefficiency losses ([itex] I^2R [/itex] losses) of directly connecting a battery to the capacitor as described, but let's ignore that for now. One thing at a time. Concentrate on 1. for now. Perhaps we can come back to 2. later. [/QUOTE]
