I recall a long time ago seeing an article on experimental devices that take
advantage of the action of waves to generate electricity. I don't know
exactly how they work, but perhaps a moving coil/magnet assembly attached to
a balanced arm which would conceivably generate small amounts of electricity
as the waves cause it to move.
