The world’s first wind farm powered by giant kites is to be built in Britain. Twenty kites flying higher than the Shard, Britain’s tallest building, will work in pairs to generate electricity. They will fly in loops at more than 100mph, with their movement pulling on a tether wrapped around a rotating drum on the ground linked to a generator. The kites take it in turns to fly out and back, ensuring that the power supply is constant. Kite Power Systems (KPS) has successfully tested a 40 kilowatt version and this summer will test a 500kW one at West Freugh, a former RAF base in southwest Scotland. The company, which is backed by Shell, plans to build ten 500kW systems about 600 metres apart. It plans to announce by September which site it has selected, and build to it by 2020.
