Vestas V164-7.0 MW turbine animation

[hygenindia]

It is 21,124 ....(twenty one thousand .......M2) ...comma and not a fullstop..

[rbz12run]

Large turbines in large numbers = great potential for generating baseload power. Keep it up Vestas (and others)!!!

[Jibberjabberjobber]

@uSuckHahol the blades are 164 metres long from root to tip - that gives you an idea as to scale.

[jnielsen20]

@Jibberjabberjobber, thats not correct. The blades are 80(262,5 feet) meter long, and the hubs' radius is 2 meter(6,6 feet). Resulting in a 164 meter(538,1 feet) diameter of the swept circle!

The Enercon E-126 still makes more energy: 7,5MW!!!! And don't need such a big

rotor diameter!!!!! But sadly, the E-126 is not built for offshore........

[AceMcMoron]

@VestasBurnsWell

That's the point of going offshore mate... :p

Offshore nobody cares how large they are, it's a solely a question of delivered Wh/cost.

[TheDeadlyKind]

Had I the money, I'd take 7.

[Doa744]

pff the enercon E126 is far superior

[jnielsen20]

@Doa744 considering that the E126 has a swept area of only 12,668m^2 compared to the massive 21,124m^2 of the V164. It's safe to say that V164 will out perform the E126 measuring the amount of time at peak production rate.

The only thing the E126 has is a bigger power production capacity, which it won't use much because it doesn't have a gearbox.

[Doa744]

@jnielsen20 because the E126 doesn't have a gearbox the swept area and windspeed can be a lot lower then lets say the same size of turbine with a gearbox

[jnielsen20]

@Doa744, yeah, but a smaller swept area means less time at peak production. So even if the E126 has a much more efficient (and expensive) generator, it's much less able to reach it's peak production level than the v164.

Secondly the huge swept area of the v164 combined with the gearbox, gives the v164 a very wide range of windspeeds were the turbine will produce power at the maximum level.

[Doa744]

@jnielsen20 i don't get how you can think traditional gearboxes and high-speed generators are then bigger low-speed generators. they are also more reliable and have lower operating costs.

if you need less wind to generate the same output then why would you have less time at peak production?

i'm open for your logics but i currently don't get it :)

[jnielsen20]

@Doa744 what you need to look at is the power curve for a given turbine, whether you look at the V164, E126 or whatever turbine. The power curve shows how much power is generated at a given windspeed. Keep in mind that windspeed * air density * area = available energy ; since the first two are constant for both turbines, the area part becomes the deciding factor. Thus bigger area = more energy available. The v164 has 12668/21124*100% ~ 60% more energy at any windspeed that can be harvested.

[jnielsen20]

@jnielsen20 ****ing 500 char. limit. The 60% is extra energy allows the V164 to archieve peak production earlier and the gearbox allows the turbine to maintain peak performance until cutoff speed.

[Doa744]

@jnielsen20 ic, thx for information :)

[Sleor]

what about the turbines ecological footprint? Bigger stronger turbine builds need more energy in comparison of smaller ones.

[OBAMASTINKSLIKEANAPE]

Securing the poverty of future generations thru the use of unreliable energy sources.

Giant checks from the US taxpayers to subsidize a worthless technology.

[TheBigBADaZz]

good job with the 7MW turbine but I am still waiting on the 10MW to come out

[zexsir]

@uSuckHahol Think of it this way one blade is about double the size as the ones you see on land

[dakoffran]

how would this hold up against ...say... a hurricane like Katrina, or larger??

[flyingpigstuff]

Australia + Bass Strait and tidal engines. Tides in Bass strait exceed 5.2 kilo tonnes. The mouth of Port Philip is over 12 kilo tonnes.

Bass strait could power Australia but then there is the Wild West of Tas, The roaring forties and endless winds exceeding 60kl/h.

[kenley1973]

100% Lækkerness ;-) But... erhm ... Why did they put this offshore-giant up in downtown London? *hehe*

[giuseppegrg1974]

W Vestas!!!!!!!

[AncientDoor]

uk win win ;P

[The619619]

So, based in london, uh?

[abkalmo]

@The619619 Vestas is Danish, but wind power is increasingly on the agenda for all the nations around the North Sea; from Denmark to Norway, the UK to Ireland.

[Danielitz123]

am I supposed to use the word "Epic" in the comments?

[mschdk]

I'm aware that UK is a big market for offshore turbines, but WTF went wrong with all the London thing???

[snaksnik]

@mschdk

It was officially launched in London

[Landstedts]

There is only one word to describe this. AMAZING!!

It´s hard to understand the size but when you see the helipad at the back of the nacelle it gives you the proportions.

[rif42]

@Landstedts

Yes it is huge but not that huge, there is no "helipad" on the nacelle. A helicopter is never going to land it will hover above and winch servicemen down onto the "helipad". Note also that there is a fence around it, you would not have that on a helipad.
