New Style VAWT (Vertical Axis Wind Turbine)

[PJs]

I ran across this and thought it should be posted for all the DIY Alt Energy folks.

The small company is called "IceWind" started by two engineers and founded in 2012, in Iceland.

It is one of the most simple foil designs I've seen and is completely scalable. It also has from what I could tell a very simple over-speed controller (probably a centrifugal clutch) which allows it to run in winds form 2m/s to 60+m/s and disengage for hi-velocity gusts which are surely prevalent in Iceland. Note that the larger units have a dual inverted foil design for more effective transfer and probably radial bearing load at higher rpm's. Truly a simple, elegant design in my book.

The scalability of these make them very useful for all kinds of sub-implementations like their bus stop WIFI/USB Charge station, lights and advertising. Additionally they are experimenting with hybrid PV (photovoltaic) and VAWT systems. The idea of these scalable units with hybrid possibilities is something I've been interested in for years.

Hope you find some value in this as I have. ~PJ
