E.ON to Invest Millions in Energy Kites
The general idea is: at 450 m altitude the winds are much stronger and persistent than near the ground. So have an air-born kite with propellers generate energy for you and send it to earth through the cable. Typical power gain: 30 households. Prototype installation to be build in Ireland by German energy giant E.ON and Dutch startup Ampyx Power. A power plane lifts off on its own and once at operational altitude starts to generate energy. Claim: 20 times as much energy per installed device mass unit as conventional wind turbines.
Obviously most suitable for not too densely inhabited areas.
