Magenn Air Rotors: Floating Wind Turbines

Migrated Image

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." The first units in production will be a 4Kw residential unit that will cost ten thousand dollars, and can be ordered this spring from the Ottawa-area company.


Magenn Air Rotor System is less expensive per unit of actual electrical energy output than competing wind power systems.
* Magenn Power Air Rotor System will deliver time-averaged output much closer to its rated capacity than the capacity factor typical with conventional designs. 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.
* Wind farms can be placed closer to demand centers, reducing transmission line costs and transmission line loses.
* Conventional wind generators are only operable in wind speeds between 3 meters/sec and 28 meters/sec. Magenn Air Rotors are operable between 1 meter/sec and in excess of 28 meters/sec.
* Magenn Air Rotors can be raised to higher altitudes, thus capitalizing on higher winds aloft. Altitudes from 400-ft to 1,000-ft above ground level are possible, without having to build an expensive tower, or use a crane to perform maintenance.
* Magenn Air Rotors are mobile and can be easily moved to different locations to correspond to changing wind patterns. 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. Read more at ::Magenn Power thanks, tipster Mac!
