Re: Tidal?
Submerged turbines in tidal races are only just getting towards production.
Something I have wondered about is why I have not heard much about any efforts to submerge turbines in deep water where there are strong currents, tidal or otherwise. Besides maintenance issues, I would guess they would have fewer problems to overcome than other renewables. It would seem that they wouldn't pose more environmental issues than windmills, shouldn't get in the way of shipping, and would be a lot more reliable in terms of hours of production than wind or solar.
