Does a Clean Energy Giant Rise Power Beneath the Waves?

These people say:

A groundbreaking study from Florida Atlantic University reveals that ocean currents can generate 2.5 times more power than wind farms, offering an untapped, constant energy source. Unlike wind and solar, which depend on unpredictable weather, ocean currents flow steadily—day and night.

So, what does this really mean?  Not much.

Ocean current energy, as it’s called, is not theoretically impossible.  In fact, until about a decade ago, there were dozens–possibly even hundreds–of teams all around the world experimenting with different approaches of extracting some of the kinetic energy from moving water.

But then came the plummeting prices of both solar and wind, leaving this and all the other flavors of hydrokinetics far behind in the competition for cost-effective sources of energy.
