Just guessing, but it would seem you could harness tide power by putting a series of two-way turbines in a constriction of a channel that leads to a large bay or straight. That water is going to come through, so with the right size opening it seems like you could get both velocity and volume to turn the turbines. I'm sure there would be environmental costs of some kind. Perhaps there might be some way to harness electrolysis in the ocean. I learned about that when I had to by new zincs periodically to lure the electrical currents away from the expensive parts of my boat. There's no free lunch.
