Maybe you still missed the joke. You said "bowing" when it appears you meant blowing.

I lost track. Are those powers (still) served with direct drive permanent-magnet generators? Or electrically excited maybe?
joe
I thought they did asynchronous generators with capacitor excitation and soft-starter grid connection at that time. Oh, that my have been a decade later?

I think he actually meant 'bending'.
joe
From about 2010 and forward all the major players more or less shifted to f ull scale converters (all the power through the converter) and PM generator s (some went all the way and made direct drive machines, but they are more expensive due to the price and availability of rare earth magnets)
I think Siemens actually reverted back away from direct drive, but cannot t ell for sure

mills really work & make sense all round, but we don't seem to be anywhere near that, and building lots of problem machines doesn't seem to get us clo ser to it. Build experimental ones that show real promise, yes.
he turbines were big business way back in the 90'ties. In the 00's it was b ased on double fed converters. In about 2010 they released their first 3MW full scale converters (I worked on that one). Now they are up to 8MW full s cale converters. Siemens and other manufactors has been in the same game al ong side Vestas
so the generation technology is still frequently changing and the wind harv esting technology problematic. What possible basis can there be for believi ng the technology to be mature? I expect some said the same of the Ford mod el A.

The technology is changing like in all business. The technology is mature.
From your thought process we should still be using an asynchronous inductio n machine with low efficiency
Not often I tell people off, but your comments are really stupid
Spend just 5 minutes on google reading up on wind turbines and failure rate s and then we can discuss further

Yeah... hot boilers bend all the time. Just look at the Titanic and where it bent.
"Bending" is more permanent-sounding than "bowing". Think bow and arrow, not bow and stern (or bow and scrape).
"Bowing" is a term used in optomechanics for the tendency of straight things to become curved when you apply a transverse temperature gradient.
It's also called "the hot dog effect".

Right. Although I have to admit he did write about boilers be "Big steam turbines have turning gear. They slowly rotate the shaft while it's cooling down, to keep it from bowing."
I still think 'bending' comes nearer to this meaning than 'blowing'. And as the word 'bowing' apparently didn't ring the necessary bells, I just tried to clarify that by using the, maybe less appropriate but still getting nearer, word 'bending'.
And this is as far as I'll go with this misunderstanding. :)

I've certainly never suggested anything of the sort

of no relevance whatever. Clearly you've got completely the wrong end of th e stick.

Dong Energy to commission world largest wind turbine farm by 2020, a total of 1.2GW
Cheers
Klaus
Or, more accurately, 0 to 1.2GW, depending on the windspeed.
If you look at the generated windpower for all the UK windmills, you can see that over the course of a year there is a surprisingly linear relationship between the relative power output and the proportion of the time the windmills are generating less than that output.
In other words, as a rule of thumb if the peak power output is 100units then 1% of the time windpower will be
If the aim is to reduce the consumption of fossil fuels, in an attempt to reduce release of CO^2, then it would be of concern in any purchase, if an alternative was available.
RL
If you're "making" fuel/energy, it' reasonable to look at the energy consumed in making it vs the useful energy output. If you're making something that consumes the fuel, it's a ridiculous exercise. Since you keep arguing the point, my guess is that you'll never get it.
... the world's biggest Dong Energy windmill.
The amortization of hardware cost in wind energy generation, as incorrectly portrayed in the partial quote by the OP, was debunked by the source article on Day One.
My contribution was to attempt to get you thinking about the actual reason behind the adoption of wind energy. As consumers of energy, our choices in the reduction of consumption of CO^2 producing energy is limited at the root supply. The bulk effect of consumption can only be levereged by cleaner source adoption.

Let me guess... money?
and that's the marketing
