Mrs B will like the look of this!

A question and observation
1) The turbine reahes Pmax @14m/s but shuts down at 15 m/s. This seems to be a great shame
2) The turbine power curve is quoted at irradiance conditions of 1000W/m^2. How does irradiance effect the power output?

The power curve on the website graphic and the one in the manual seem different. Am I missing something obvious?

Maybe the blades melt if irradiance is over 100W/m2
A good looking turbine.
BUT manual says it can be installed on an attic, though, I wonder what Martin will make of that.
"If installed on an attic, we recommend that the designer responsible for installation verify
the structural strength of the attic, taking into account both contemporaneity factors required
by local laws and regulations (usually the weight of the attic, snow and anthropogenic loads)
as well as the weight of the wind generator and the stand." 
And there is a whole section on roof mounting, Quiet Revolution eat your heart out.

rhys,
     you might have picked that up wongg,
                               maybe it says ,,it can be instored in an attic,, ; not many work in the attic,,

Easy peasy lemon squeezy, a stark choice.......

[Ted]

Over £4k for a 500W (at 11 m/s) grid tie system?   

[rhys]

This looks like the turbine that was developed allegedly with Phillippe Stark a year or so ago, which explains its good looks.
It may also explain ............

Ah yes here it is for those interested.

Doh just realised Martin was there already 

[Ted]

Oh no, I love Starck.  His TV series taking a group of designers through an 'Apprentice' style job application process was unmissable.

He is all about pragmatic use of design - so can't explain the price, can it?


[edit - this from the comments on Rhys' link]

From “Democratic” to “Capitalistic”…. You originally reported that the quadrangular one would be about 400 Euros:

“The windmill can generate 20-60% of the energy needed to power a home, at a price point of around 400 Euros ($633). Not realistically within everyone’s budget, but by combining creativity and elegance with ecology Starck will hopefully encourage more people to take greener steps. And for those who don’t want their conservation pieces to be conversation pieces, a subtler version has been proposed.”

Now the same turbine is going to be 2500! Design may be dead, but capitalism is surely not. A real revolution would be a 1Kw turbine for $500.
