Tidal is in the news again

February 4, 2012

–From GOOD Magazine–

“Tidal and wave power do carry some environmental concerns: Early projects are studying how turbines affect fish, for instance. But because these projects live under the water, they could avoid complaints like those that dogged the offshore Cape Wind project about ruining scenic vistas. The East River project has been running turbines on and off as part of a pilot project for years, and New Yorkers, a grumbly bunch, have yet to kick up a major fuss. Most people driving over the Queensboro bridge and gazing down at the river probably never guessed that a power station lies quietly beneath the water.”

It wouldn’t surprise me to see these “environmental concerns” surrounding tidal begin to disappear as people become more acquainted with it.  Many who imagine getting power from the motion of the ocean imagine the infrastructure as being something akin to a wind turbine in the water – this isn’t true.  While there are many different turbine models, most don’t pose a danger to fish because the turbine blades spin faster than the water surrounding them, which creates a force directing fish away from, not toward, the turbine.

Either way it’s great to see tidal power continuing to get its due – with people realizing that the lack of visibility is also a huge and understated benefit.
