Who would have thought that something as fun as flying a kite could end up being energy producing! While pondering how to capture wind energy, scientists from the Netherlands went out and flew a giant kite. The 10-sq-meter kite was tethered to a generator and managed to produce 10 kW. With the success of this kite, they’re planning to test a 50 kW version of the kite, dubbed Laddermill, and if that succeeds, they’re proposing a multi-kite version that could get as much as 100 MW – enough for 100,000 homes.
The kite generates energy by pulling on is string on the way up. When it gets to the end of the string, it’s pulled back down and then sent back up for another flight. The amount of energy captured is maximized by flying the kite in figure eights, and bringing it down in a fall like a glider plane. Check out a video of it by clicking here and read more at ecogeek.
