Ottawa, Canada-based company Magenn has developed a "floating wind turbine" for personal and infrastructure power generation. The helium-filled device floats up to 1,000 feet into the air, using high altitude wind gusts to generate power up to a kilowatt. The power is transfered down via two "tethers" attached to the turbine.
Magenn states that its compact design and flexibility eliminates the risk of birds getting chopped up near it, a problem associated with standard fan-based turbines. It looks a bit weird, but most out-the-box ideas usually do.
