One thing that puzzles me about big turbines like this is that I don't see any sort of vane to keep them pointed into the wind. Do the blades adjust on each trip around to help the thing swivel, or does the wind just always blow the same direction at that altitude?
Regardless, I want to live in one of those - kind of like the modern-day equivalent of a light house keeper.
@EBone: you have to think about that in terms of cost per kw... wind is generally competitive (as of 2 yrs ago at least when i looked last) once you add in the production tax credit which is a govt subsidy for every MWh produced. that said wind is a joke, until they figure out how to efficiently store electricity. never blows when you need it, and people generally don't live where its windy enough... and the intermittency means you can't rely on it as firm grid capacity, its just a side resource that sometimes generates a bit. and you can't really compare a nuke to any other plant in terms of cost to build bc it takes a huge capital commitment and there are long lead times for permitting...
anyway wind won't ever replace a baseload generator (like nuclear or coal) without a natural gas fired plant nearby that can turn on when the wind stops blowing. just annoys me that so many people think wind is the answer. it'll be solar (prob thermal), if anything, once they get cost down.
@EBone: ah fair enough, i shouldn't have assumed you weren't aware.. apologies for the condescension, the aforementioned annoyance took over i guess.
anyway for what it's worth, sounds like obama and the rest of the country seem pretty convinced on wind's viability... as a genuine question for curiosity's sake, has your company ever seriously explored pairing a wind farm with a pumped storage facility? i've kinda always wondered whether that was even possible, geographically or cost-wise.
@accordionhero: No worries. We're actually exploring a number of different storage and pairing options right now. One of our Texas projects is about to be supplemented by a 25 MW solar PV facility. It works great since TX gets lots of sun during the day and the wind blows pretty steady in the evening. And a CA project is tied to the LADWP's Castaic Lake pumped hydro project for load balancing.
We're also exploring battery storage, compressed air storage, and spinning flywheels. Right now none of those technologies are perfected or cost effective, even with the PTCs in place currently. We expect these technologies to be more mainstream in the next five years or so.
It still boggles the mind that humans can design and build gigantic structures and machines such as this. What's even more unbelievable is that some of the largest structures were built before computers existed, such as the Hoover Dam.
i work with a company that makes the bolting that goes into those wind towers... next month is a trade show in Chicago for the wind industry .... and they have the blades and hubs they go on ... and i can tell you they are as big as some homes
Smithers, i've designed a new plane, I call it the Spruce Moose, it will carry 200 passengers from New York's Eidlywilde to the Belgian Congo in 17 minutes!!
I'm proud to say that 252 megawatts of that new power was developed, constructed, and is managed by my company. In case you're curious, that's enough energy for about 100,000 homes annually.
Wait, this can't be true! We became #1 in Wind Power production while Dubyah was in office! But, that's not right! Awwww people of Sherwood Forest we've been had, bamboozled, flimflammed... We didn't land on wind power, wind power landed on us.
This is great news! Obama is going to DOUBLE the production of renewables...so in the next few years it's going to be very promising, slowly releasing our thirst for oil.
I just can't wait for a time when electricity and clean energy are rife, clean air....mmmmmm. Knowing that using energy is not damaging anything, so i can use things without any 'guilt'.....twenty years from now the world will be a very different place, especially when considering China is making HUGE efforts to come out of the recession in a 'green' way
@Luke Thornton: People keep talking about reducing the thirst for oil, but there really aren't enough electric powered vehicles on the market to do this, or even coming to market in the next 4 years.
Most plants are coal or natural gas powered in the US. Not OIL powered anyway.
I think you mean cleaner energy sources here. It's going to be a LONG time until we're really off of oil.
But, what about the noise pollution from windmills? Or, you know, the fact that they kill birds? Even wind power isn't perfect here.
I'm glad we're pursuing alternative fuel sources, but I can tell you that ethanol is a sham and yet another way to starve poor people.
@Lite: must go faster.: OK, seriously. If a bird can't spot a whirling 150 foot blade, perhaps it's good we eliminate that bird. It seems that's the kind of bird who would ignore a plane flying at it until it gets sucked into the engine.

man, a decent nuclear plant is rated at 1000 megawatts and higher.
