[Keelynet] Focusing wind flow with surface area to better drive wind turbines

[Jerry Decker - KN]

Hola Folks!

With regard to this 'new' invention as posted today, it seems the more 
surface area you can use to guide wind, smaller and lighter the stacked 
cup rotor could be. I think his patent is worthless since its just a 
stacked Savonius but more power to him for DOING something about it.

Imagine a giant X lying flat on the ground with the rotor in the center.

This X is basically 4 big square or rectangular panels that serve to 
focus the air through the X center.  Thus a lot of wind would be 
funnelled in to force its way through the rotor, which turns a generator 
for electricity.

The diagram and Savonius comparisons are on www.keelynet.com for today 
and tomorrow, then it will go to the November 2005 archive where it is 
still accessible.

11/09/05 - Energy crisis answer is blowing in the wind

Inventor Alfred Learmonth reckons he has solved the world energy crisis 
with a generator made of cardboard. The prototype is a row of cardboard 
cups attached to metal rods that harness the power of wind or waves.

The beauty of the invention is that it will continue to generate power 
even if the wind changes direction. Retired engineer Alfred, 80, from 
Macduff, Banffshire, came up with the concept two years ago. But it was 
his grandson Damien, 12, who insisted he put the idea into action.

Now Alfred has patented the energy generator and is looking for a backer 
to develop it commercially.

(I managed to locate his patent, captured the image and cleaned it up a 
bit for clarity. As you can see, it is a series of stacked Savonius 
Rotors which are indeed highly efficient and very easy to construct from 
any cylinder. - JWD)

W.W. Generator - Patent number: WO2005098233 - Publication date: 
2005-10-20 - Inventor: LEARMONTH ALFRED (GB) -

A wind or water driven generator built as a double helex around a 
vertical drive shaft that traps and maximizes any current it is exposed 
to. This device can be built to any size or width as a single unit or 
clustered within a framework which makes it suitable for land or 
offshore installation.
