How cool is this, they have been talking about tidal energy for years and now the first two turbines have been connected to the UK's national grid. It is also scalable meaning they will be able to add more turbines as time goes by. 

Full Story

Yeah that is good. Like you say it's been years, even decades. Since we're surround by water it makes a great deal of sense. 

Bet they're pricey for the lecky they give but hey, you have to start somewhere.

Scaling up should reduce costs and being composite blades should be good on corrosion and maintenance. Found this article, looks like they've been having problems with the 30kW version.

QuoteThe local Cullivoe ice factory, which was supposed to be powered by the Nova 30 tidal machine along with an industrial estate and 30 homes, has switched off the connection because the turbine allegedly drained more energy than it generated.

But looking hopeful.

  And it doesn't work.

Oh, I think it does work but early days. At the moment the 2 turbines are putting out 1.3 million watts.

I like the site but can't find Bluemull Sound turbine. Should be here but no indication on this map... yet.

I think you might be right Snowy, I can't find Bluemull Sound turbines on the map either but I can find the total tidal power out-put.

And it's still showing today, if you navigate to Wave & Tidal Energy then drill down to "Active and Currently Generating".
