Just seen this on the BBC News.

Ecotricity, a UK 'green' electricity supplier are constructing a 70m turbine with the capability of 2MW output, and is said to be 'Britain's most visable wind turbine.'

Location: Green Park, Reading, Berkshire (M4,J11)

Info: http://www.ecotricity.co.uk/acrobat/GreenPark.pdf

I'm not too sure of the safety aspect of the location tho... close to one of the UK busiest motorways and Reading's football stadium.

Ecotricity's website is here;

and take a look at the projects on the page here;

even the tyre manufacturer Michelin are getting in on the act to reduce their grid demands (& 7000 tonnes co2 emmissions/year)

Ecotricity also supply electricity to homes, via the grid, promising to match local suppliers' prices... and invest profits back to developing and building wind turbines.

does any 1 know how fast tip would be going at 22 rpm on that monster?

[nanotech]

290. 283 KM per hour.
     
70. m diameter * pi = 219.911m circumference.
    
219. 911m circumference * 22 rpms = 4,838.052m per minute.
     
4. ,838.052m per minute * 60 minutes in an hour = 290,283m per hour.
   
290. ,283m per hour / 1,000m per Km = 290.283Km per hour.
     
     

Or roughly 180mph.
