So what are the real power outputs of the windmills? Three 1200 meg power supplies can power three medium-sized cities. I work at a 600 megawatt power station that supplies roughly half the power for Pittsburgh, so 300 homes seems to me it might be a pretty low estimate for something that size.

The real output is 225 kw per turbine. The projected energy yield from the turbines, taking into account wind and availability data, is estimated to be:
Turbine #1 340–400 MW h/year
Turbine #2 360–430 MW h/year
Turbine #3 400–470 MW h/year
This amounts to between 1100 and 1300 MW h per year and will amount to
approximately 11–15% of the office towers’ electrical energy consumption. In carbon emission terms this equates to an average of 2900 kg C (oil-burning power station) or 2000 kg C (gas-burning power station). These figures are conservative. Since this is a world first and because wind turbines have not been placed 160 m above ground level and between buildings, the yield may even be higher. See www.norwin.dk for more details.

Thank you very much, I'll definitely check out your site.

I suspect that these towers have thick, double pane maybe even triple pane insulated glass anyhow, but I wonder if there still might be a noise issue in the nearest habitated rooms?

i believe green should be smart. it should not cost anymore than nongreen, or be an inferior product. this gets my GREEN N' SMART seal of apoval.

i think it would be better to add another turbine, though.

woah! thats a pretty set of buildings! =)~

I think they intended to say "1200kW" output, which refers to the peak power output of the turbines. 1200 MW is a huge amount of power and no wind turbine this size could possibly put out this much power.
The intention could have also been to say "1200kWh", which refers to the annual energy output of the turbines.

This is definitely a good idea, we can all learn something from the boundaries that are being pushed in the UEA.

The Wind Technology looks good and it is a good project to use a test project.

However you should know something about Bahrain & it's neighbor Dubai whose world tallest skyscrapers are amazing. They employed poor and desperate foreign workers at almost slave wages as construction workers. They have miserable conditions and in essence are indenture servants. See http://www.iht.com/articles/ap/2008/05/25/africa/ME-FEA-GEN-Dubai-Towers-of-Tears.php

Who cares if its green when it is built on the backs of the poor working class being mistreated?

for those not familiar with converting numbers across the pond:

most of the world uses a comma where we in the states use a decimal point.

If you notice: 1.200Mw = 1200kw = 1,200kw

But, in europe - and dubai - 1.200Mw is written 1,200Mw

Clearly someone got sloppy w/ the cut & paste. If you look up above at the figures per turbine they do in fact add up to 1.200Mw (or, for practically the entire world: 1,200Mw).

The is simply an error in the translation of mathematical symbols.

I found this article very interesting and I was excited to find out that buildings were starting to use different sources to get energy. These buildings are a good example of using alternative energy sources, and they look great. I would be interested to find out more about these buildings. It is amazing how much energy they are getting from this new technology and exciting that they are looking for alternate ways to power their building.

I suspect the the sandy environment is going to plague the dependable operation of these power plants

What IF like, the wind happened to be blowing incredibly fast, and the turbines couldent take the stress, would it be possible at all for them to get riped off and go spinning into the towers? (somewhat like in The flight of the phoenix, where they loose the prop and it goes shreding into the fusealage...?)

"it rips the propeller off and slices into the body of the plane like a buzz saw."

Anywhere near possible?

First of all, that island doesn't get much wind... the gap between the towers and the tapered shape is a brilliant idea. This idea would bring in the required wind. Secondly, dust is no issue... that part of the town doesn't get hit with dust often. I was there summer 08, that part of the town is developing really fast. The Bahrain Financial Harbor is coming up nearby these towers, along with some other towers.

About the workers, majority of the workers are from the sub-continent (India, Pakistan, Bangladesh and Nepal). Sure, they are poorly treated, paid low wages and have a sad lifestyle. For most of them, they chose this path... others were conned into this by their own people (Local manpower services). I don't know about Dubai, but Bahrain had given these people a chance to go back home if they were flown there by force or tricked onto. I know this because Im an Indian, born and raised in Bahrain. I have seen all this.

Companies (actually sub & sub-sub contractors) hire such people. They were told, they would have better jobs but instead when they arrived to Bahrain, their sponsor took away their passports (so that they dont flee), and then were thrown in the dump and made slaves. They are paid low, because the working visa costs a lot of money, the sponsors wants it back, hence cheap labor for a long time. Check out this link, 16 Indians were killed in a fire in a building. This building was actually used as a CAMP, housing illegal number of residents. http://www.islamicawakening.com/viewnews.php?newsID=8138& (OR google the news). This shows how they are treated. But things are getting better than before. The governments and the embassies are cracking down on this conning/tricking. But this will never end.
