A traditional childhood pastime could provide a breakthrough in renewable energy, after successful experiments in flying a giant kite at one of Europe's top research centres.
Scientists from Delft University of Technology in the Netherlands harnessed energy from the wind by flying a 10-sq metre kite tethered to a generator, producing 10 kilowatts of power.
The experiment generated enough electricity to power 10 family homes, and the researchers have plans to test a 50kW version of their invention, called Laddermill, eventually building up to a proposed version with multiple kites that they claim could generate 100 megawatts, enough for 100,000 homes.
Wubbo Ockels, a professor of sustainable engineering and former astronaut who leads the Laddermill project, believes kites are a cheap way to harvest the enormous energy in the wind at a kilometre or more above the ground, where winds carry hundreds of times more energy than on the ground. 'We need to use all the energy supplies that are offered to us by nature, we need diversity and kites are ... intriguing and fascinating,' he said.
Ockels is not alone. Google.org, the philanthropic arm of the Californian web-search company, invested $10m (about £5m) last year in a US kite company called Makani, one of the first awards as part of the organisation's Renewable Energy Cheaper than Coal programme.
