...his proposal could open “a lot of the North Sea” to tidal stream energy, which generates power from the movement of the oceans.

The idea is to co-locate specially designed “Tide-Torrent” turbines on the sea floor alongside offshore wind farms.

Water moving past wind turbine foundations gains speed, McAnally said, suggesting smaller tidal generators could be positioned to capture that extra energy.

Could this simple idea 'revolutionise' Scottish energy industry?

A NEW tidal turbine design could “revolutionise” the renewable industry in Scotland, its creator has claimed ...

@JackTheCat
Would love to see tidal-powered electricity generation working, but it's been decades (tried/failed to include it in a doc back in the 90s)... though mechanical watermills used tidal pools, back in the day... #turnthewheel #howmuchisenough

@JackTheCat Well, they ran a trial version of this technology in Strangford Lough a few years ago. The destruction of species was such that the tidal turbine was removed well before the end date, and everything promotional and positive about it went very, very quiet.

@HarriettMB @JackTheCat Yep, this is the problem.
Fish don’t like turbines any more than you’d like being in a washing machine.
And the seabed is (or should be) full of life, and is a bad place to put a turbine.

Need something that goes with the laminar flow of the tide.

@BashStKid @HarriettMB @JackTheCat Tidal energy is also really diffuse. I suspect that this is one of those ideas that sounds good until you start doing the arithmetic.

@tokensane @HarriettMB @JackTheCat Still a problem that needs solving, 15% of the world lives on a coast, they need energy, and they need a healthy sea.

Probably one or two percent of the the money pissed away annually on AI would solve it …
