Seriously... At least it seems more potent, or less impotent than wind
power. There is always demand, so I presume this means they can ramp the
gas generators down a bit which is a good thing.

On paper, tidal power is very appealing. The energy density of moving water is
very high. But as far as I'm aware there is still no commercially viable (i.e.
profitable) tidal current turbine facility in operation. I'm referring to a
turbine that is just plonked down in a spot with high currents, not to a
facility with a dam and/or gates.

The marine environment is very challenging. Highly corrosive, teeming with
life, very high loadings, unfriendly to workers.
