Gadgets, gizmos, and tools to help make you more productive in business

Because the wind blows in different directions, because there isn't a constant air flow to get through and because not all regions get it, traditional turbines are no longer very efficient now that Mageen Power invented the airborne wind turbines. Apparently "at a thousand feet, there is steady wind anywhere in the world" said Mac Brown COO for Mageen.

The company got a $5 million funding and managed to develop a lighter-than-air wind turbine that is filled with helium and has a 100-foot-wide Mageen Air Rotor System (MARS) that spins around a horizontal axis and produces 10kilowatts of energy. The whole turbine is wired to the ground with a copper cable and send energy down to be used (it can light up a small village) or can be stored in batteries.

There is a small concern about birds that would die flying inside. Mac Brown assured that being so big, bigger than a house, a bird would see it and a bat would sense it.

Mageen Power got the paten for their MARS turbine in October and I can tell you I wish they'd start producing on a larger scale if there aren't any airplanes/helicopters problems related, because it's a very important source of energy involving minimum levels of pollution.
