World's Largest Wind Farm Gets Green Light

cliffski writes "According to the BBC website the UK govt has just given the go ahead to two large offshore wind-farm projects. Between them the schemes would produce enough renewable electricity to power about one million households. The larger London Array project covers 144 sq miles (232 sq km) between Margate in Kent and Clacton, Essex and will be the world's biggest when it is completed. The £1.5bn scheme will have 341 turbines rising from the sea about 12 miles (20km) off the Kent and Essex coasts, as well as five offshore substations and four meteorological masts"

Mobile Farms

Why don't they put these wind farms on barges floating around the seas offshore, where the winds blow steady and reliable? Relocated when economical according to satellites tracking the seasonal winds.

Barges covered with solar cells. And reverse-gyroscopes that generate power from waves and currents. They anchor landmines, don't they?

Compare the number of bird deaths from those windfarms to the number of bird deaths (and non-bird deaths) that would result if it was a coal burning power plant instead. Every project has costs (not all costs are $$). Hopefully the people in charge weigh the environmental costs as well as the monetary costs (sometimes the environmental costs end up being monetary costs anyway). Most large scale power generation techniques have an environmental impact.. The question is - do the benefits outweigh the costs?

Tides

[pubjames]

I've never understood why the power of tides is not exploited more. In a short streach of coast around the UK, hundreds of millions of tons of water must be moved every 24 hours. I'm sure there must be a lot more energy in that than in the wind in the same area. Why isn't that exploited? Anyone know?
