VAWT redesign
 

Vertical Axis Wind Turbine (VAWT) Type: Pivoted Panel
 

http://www.youtube.com/watch?v=Tgq4TC2etag&feature=fvw The Pivoted Panel Wind Turbine will tap its power from the perimeter rather than the axis. In doing so and when implemented, this system will eliminate or greatly reduce the need for a step-up gear.

An animation of a vertical axis wind turbine that I created in 3DS Max. These things are real, and are supposed to be more efficient than the standard three-blade windmill-like turbines. http://www.youtube.com/watch?v=c052h...eature=related

New Wind Turbine Design Good for Rural, Urban Environment
 

http://www.youtube.com/watch?v=fNudn...eature=related Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates.

The Worlds Largest PMA's
 

http://www.hydrogenappliances.com/pma_large.html We Make The Worlds Largest PMA's

SLOW TURNING - HIGH POWER!

LOW RPM Permanent Magnet Alternators. (Very rare)

We ONLY custom make this PMA line so it
takes about 3 months to build our really big ones.

We start out with AC motors and totally gut them and install magnets and windings!

These are very rare 135 Pole ultra slow turning, super slow speed motors.

The DC units are Single phase and the AC units are Three phase.
What makes these PMA's SO special is that some develop full
power at only 140 RPM! Perfect for large direct drive props.
