On a day when the British don red plastic noses -- and other comic paraphernalia -- in aid of good causes, a wind turbine overlooking the UK's busiest motorway joined in the fun. Red Nose Day is a fixture in the UK calendar when individuals, organisations and schools across the country raise money for Comic Relief, which helps tackle poverty and social injustice in the UK and Africa. The 225 kW turbine, at the UK headquarters of Renewable Energy Systems, received its own red nose, painted by staff from Vestas. It is seen every day by motorists using the London orbital M25 motorway. Proceeds from the sale of electricity it generated for a week were donated to Comic Relief.
