Kite System Could Generate Energy for 10 Homes

LaddermillB.JPGWho knew a single large kite could be used to generate enough energy to power ten homes? According to Delft University of Technology in Netherlands, the potential wind energy to be harnessed at 30,000 feet in the air is twenty times of what could be harnessed at sea level. To test if wind energy at that altitude could be harnessed, the researchers flew a 10 square meter kite which could generate 10kW; enough to power 10 homes. The next experiments would be on a larger scale, eventually upping the energy produced to 50kW.

Ultimately, the goal is to generate 100 megawatts of power through the use of not one, but a system of kites called Laddermill (pictured left). The kites are able to produce power by tethering them to a generator on land. When the wind blows the kites, the lines holding them are pulled and energy is produced. Once the lines holding the kites reach maximum height, the kites are reeled back so they could continue to generate power. Aside from the enormous potential energy harnessed, the vertical orientation of the system would mean only minimal space would be used.
