Get the latest news and first hand Information About Engineering Technology. The Magenn Power Air Rotor System MARS is a patented high altitude 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. Airborne wind - turbines that fly in the sky and harvest energy from atmospheric wind has the potential, say proponents, of reducing the cost of wind power. This paper presents an analysis of M.

Lloyd Alter lloydalter December 13, Treehugger has shown flying wind turbines before but never one this clever- it is held up by helium. Such a simple idea- it works on both straight lift from the helium and the " Magnus effect " where "For the Magnus airship and hence the patented Magenn Air Rotors System, we have proven that as wind speed increases, rotation increases, lift increases, drag will be minimized because of reduced leaning, and stability increases.
Magenn efficiency will be 40 to 50 percent. This is hugely important, since doubling capacity factor cuts the cost of each delivered watt by half. Altitudes from ft to 1,ft above ground level are possible, without having to build an expensive tower, or use a crane to perform maintenance.
Mobility is also useful in emergency deployment and disaster relief situations. We worry a bit about our countryside looking like London in the Blitz, but other than that- what a wonderful idea.

Magenn floating wind generators take advantage of high altitude winds
Electricity would be funneled down the MARS tether for immediate use, or sent to and stored in a set of batteries. Because MARS would float well above ground-generated atmospheric disturbances and varying topographies, the turbine would benefit from cleaner, more consistent and faster air, thus producing more power than a ground-based unit. In the event of collision, the inflatable, inert and non-flammable helium-filled structure would fall slowly and harmlessly to the ground. MARS floats below legally usable airspace and therefore poses no danger to airplanes.
