Enterprising minds continue to search for new ways to turn free energy into cheap energy, and the latest gem is from KiteGen, an Italian company that believes that current wind turbine technology isn’t the wave of the future. Instead, their system sends high efficiency foils 800 – 1000 meters into the atmosphere – where winds are strong and consistent – with an automated kite flying system to generate potentially huge amounts of power. If they can overcome line drag – traditionally the downfall of any experiment involving high-flying kites – this could be interesting. And a lot prettier than a wind turbine. They’ve got a good looking video concept of their idea here, and some more detailed info here.
