MVAWT: new mag-lev VAWT wind turbine

[capthook]

Check out this new 'MVAWT': 'Magnetically-Levitated Axial Flux Alternator with Programmable Variable Coil Resistance, Vertical Axis Wind Turbine'

Large construction with many/large magnets and coils.  And uses magnetic levitation rather than bearings.

So looks like a huge axal flux VAWT.  Some questions:

1. the magnetic bearings: how well would they actually work?  while you eliminate the downward force friction, how does it stay centered to prevent friction from rubbing against the center pole?
   
2. the claims of 200% increased output due to 'roof effect' ??
   
   

Interesting!

Jesus, ADMIN, either get us a LINKS section, or put a "rule" about link pimping in the board instructions.

Any moron can spend their day link hunting. VAWT, Hydrogen both "only if you built it" policy applies. Bye.

So not ALL bearings are eliminated - just the load bearing ones.

There are still bearings on the vertical shaft to maintain alignment.
