Floating wind turbines!!

The Magenn Power Air Rotor System (MARS) is an innovative lighter-than-air tethered device that rotates about a horizontal axis in response to wind, efficiently generating clean renewable electrical energy at a lower cost than all competing systems.

The magenn flying wind turbine is held up by helium generating 4Kw, enough to power your needs. It costs around $10,000, but it could pay for itself in about 6 years depending on how you use it. It’s anchored by a tether that can extend up to 1,000 feet above ground. Generally, 400 feet is enough to catch the minimum 3 meters/sec wind speed needed to sustain a nice supply of electricity. No towers or heavy foundations are necessary and sizes range from small “backpack” models to large megawatt generating devices.
