The secret to the kite’s efficiency lies in its speed and #computer-controlled flight pattern.
The idea is for the kite to describe figures of eight, which increases airspeed, said Wrage, who has been working on the new technology for 10 years and who still enjoys flying kites on the beach for fun.
“If you double the airspeed you multiply the energy by four. That’s the secret of the system,” he added.
A new 320-square-metre kite, recently produced, “has a towing force of 32 tonnes which is more than what two engines on an A320 Airbus (aircraft) can produce. So we’re not talking toys,” he said.
