Bahrain World Trade Center Getting Its Turbines

I just got a completely unsolicited email from Shaun Killa, the head of Atkins Architecture in Dubai. This, of course, is a fantastically gigantic and price of cialis in canada important job. Basically, he is in charge of the first ever skyscraper with integrated wind turbines. So I was excited to get the email. Well, I was even more excited to see the buy cialis overnight contents. Up-close and personal shots of the Bahrain World Trade Center getting its turbines installed.

This really is a massive project. After the jump are some concept and real-life shots. Click on the real-life shots for a large version.

In the larger version of this picture you can see that the turbines will have the ability to automatically shorten and slow themselves in times of severe weather by twisting their tips.

Obviously there's a lot of work yet to be done.

And here we can see one of the big problems faced be folks working on wind power in the desert...namely...dust. If you look closely here you can actually see that someone is standing inside the turbine, where the wow it's great cialis profesional generator will be.

I love engineers

they're so inventive sometimes. Turbins on skyscapers? Awesome!!!

Awesome! Any word on how much power they generate?
great looking but...

Is it just me, or is this a giant waste of money, because the turbines cant pivot they are not going to get much wind (specially with a giant building on each side) and the air turbulence from the buildings is also going to make the maintenance costs astronomical. All for not much energy production.

No to mention the end of those blades is perilously close to the building, they start spinning at a couple hundred miles per hour you wont get me near them windows. Good thing they never get ice in Dubai, one tiny chunk of anything flowing off the levitra attorneys blades would break a lot of glass.
I suspect...

that all the aerodynamics were carefully worked out before construction. You may well find that being coastal and in that part of the world, the wind only really blows in two directions (i.e., on-shore and off-shore), and that the turbines are aligned to that. You may also find that the two towers act as a kind of cheap cialis no prescription wind tunnel as well (I'd be surprised if they didn't in fact).

As for the strength and safety of those windows, well, I don't know for sure, but I doubt very much that the building would have got planning permission if it wasn't pretty safe.

The downside of all of this is that, alas, Dubai is probably the most tasteless place on the planet at the moment, and the vast majority of the massive amount of property development happening there is quite the opposite of eco-friendly.

Neat concept. Really curious to find out how much power they'll generate, whether they're show horses or working horses.

I wouldn't worry about the proximity of best prices for cialis the props to the building, airplanes seem to manage OK.

By the way, Bahrain ain't Dubai. It's an island much further north up the cialis online shop uk Gulf. They're hundreds of km apart.
Meaningless integrated design
written by Pete, September 08, 2007
A windmill of this size creates a volume of approx. 96-101 dB(A). On top of that there are multiple identical sound sources (3 wind mills), generating another 4 dB(A). According to most building codes, the highest acceptable indoor sound level is 40-45 dB(A). It would take a distance of 300-400 meters from the sound source to the listener to reach this level. I wonder how the engineers made a technical solution to the building to deal with the obvious noise problem?

written by Common Sense, September 09, 2007
The turbines don't need to rotate, because the buildings funnel air between them.

All skyscraper construction has to take into account how wind will affect the buildings, *AND* how the wind will affect other buildings nearby.

Maybe they used a magic noise canceling pencil when designing it! Or, just maybe, they're going to use some form of double or triple glazing... Seriously, why do some of you seem to think you know better than a team of architects and the best site levitra samples in canada engineers!?

Ridiculously small wind turbines. BTW, it's better to install solar cells under such latitudes. These arab turbines are just for the "wow" effect.
Now look down at these "casual" ones (200 ft dia. propeller, 450 ft tall) in Switzerland, not really known as specialists in that matter (Germans are better), and hold back your "Awesome" for something slightly more interesting in terms of size:
And this one holds a standing man in one of the BLADES (besides, my home would fit in its generator cell, instead of the above mentionned .... mmmh ... cartrunk.) :
These, by far, are'nt the biggest ones but already "blow" those "Bahrain WTC" propeller-hat toys.
Now about noise: given the proportions, the building itself will generate way more noise than those microscopic blades. And, just for info, a "real" wind turbine rotates at a max. speed of ... 1 turn per 3 seconds. So, c'mon, "spinning at a couple hundred miles per hour"... hey, it's not an aircraft, right !

Infografix: nobody said these were the world's largest wind turbines. Or, for that matter, larger dan a certain other wind turbine in Switzerland.

The rest of you are incredible smartasses, too.

you guys are clueless
written by Jacques Mattheij, September 09, 2007

go build a windmill and learn before spouting off.

1) the blades don't shorten, they simply pivot to change pitch.
2) the turbines are small, but not *that* small, and three of what is cialis them will produce appreciable power. If the wind was going to be there anyway then you might as well use it, and solar doesn't work at night now, does it ?
3) I've stood under windmills of that size and you don't hear a thing, just a light 'swoosh' as the generic viagra made in india blade passes over you. 96 DBA is only relevant when the manufacturers paperwork is cited or you have been measuring on site. Otherwise it's just a number pulled out of the air. (or worse).
4) you'd be surprised how fast the actual blade tips go, 3 turns per second at 17 m diameter or thereabouts is approximately 200 km/h. It's not quite at aircraft speed but it's getting there.
5) I'd be more concerned with vibration, those are geared mills and they produce a bit more vibration than direct drive machines, and that vibration will be transfered to the structural member supporting the mill. From there to the building. It would need some pretty serious damping.

If it is PR then at least be happy it's PR for something good, renewable energy. Beats the shit out of some lightshow or so advertising soft drinks or cell phones.

Bahrain is pretty amazing, it's the closest nation to Saudi/in the UAE that allows alcohol so people from all around come to the tiny island nation to drink or work or whatever. But being waterlocked means they've have to rely heavily on what they have, since trade can be expensive since all foreign commerce has to go by plane or by water, so they had to find alternate ways for energy since they don't have coal, and they're not as rich in oil as their neighbours. Wind is a very effective way to generate this power, good for them and I'd love to visit the country again especially having seen all the strides they made in the past few years.

well to those think it's a giant waist of money, it's not! they project is well studied, and the turbines are supposed to save up to 15% of the power. go to any skyscraper, cut 15% off it's electricity bill, and check the grin and the faces of the accountants. of course in this case we have 2 skyscrapers.
written by NickW, September 09, 2007
Bahrain is not completely waterlocked - there's a road causeway linking it to Saudi Arabia. The joke was it was built straight one direction (Saudi to Bahrain) but wiggly in the reverse direction, to help all the Saudi motorists who had gone to Bahrain to partake of alcohol and had to weave their way back home drunk.

Before the cialis online pharmacy usa causeway was built the flight between Bahrain and top us pharmacy cialis Dhahran in Saudi was the, or one of the, shortest scheduled jet flights in the world... 15minutes, and when I took it from takeoff to touchdown it was 8 minutes, and even then we took a rather non-direct route.

The cabin crew still managed to serve all 100 passengers with a bricklet of orange juice and a biscuit/cookie, and collect the detritus up afterwards.

Then we had to wait over an hour in an immigration queue, as we landed behind a Philippines 747 with about 350 guest workers, all of whom needed extensive paperwork processing.

World Trade Center
written by Vibeman, September 15, 2007
Just read some of the comments, and cannot believe how clueless some people are.
I just left Bahrain earlier this year after being there for the past year. the towers are still in construction and are a wonder to behold. They are constructed so that the wind is funneled in between the structures as in a venturi tube. The winds in Bahrain can get rather strong so the output of these turbines will definitely generate enough power for the buildings.
1. The towers are in the Kingdom of Bahrain, in the city of Manama.
2. Dubai is in the UAE. Nowhere close to Bahrain.
3. The building are very beautiful to look at.
4. Have to admit, Bahrain is not the most eco-friendly place in the world, but it is their country.

Personally I cannot wait to be able to visit thier once again and see the buildings after completion. They are also building a financial district that wil be one of the most beautiful in the world after completion.

Just my personal opinions and observations.

I wrote "one turn per 3 seconds", not "3 turns per second". That's 9 times slower.
And, btw, claiming that 3t/s at 17m diam. results in 200 km/h is just briliant. That's 576 (non-existent) kmh.

Never too late.

All props possible for Bahrain! Ignore the best levitra price jealous that still live in backward countries of cement and steel boxes with the creativity barely above that needed for a dung beetle to roll up a ball! True inventiveness and I only wish more countries would get this inventive! Also, cheers for Atkins. Even though the turbines will only generate between 11% and 15% of the total electricity needed - it is a marvel and levitra no rx required worthy of nothing but compliments...from anybody with a brain larger than that of only here generic levitra without prescription a gnat of course. I'm sure the people of Bahrain will show it with pride to all visitors - as they should!

It is one of my favourite buildings in the middle east

Although I can't help but rain on Mr Killas parade and ask the question, with the eco friendliness of the design of the turbines, have you noticed how much glass they've used on the building? Loads!

the bahrain world trade centre will be operational within months time. some of those smart asses that laugh on the technology and design of this structure will be marked as ignorants, as they don't know anything about architecture and renewable energy, let alone a thing about this project.

the designer started something that will ripple in the history. combining both science and art. much to our enjoyment, some feebles can comment without getting themselves educated on things like these. of course it'll be easier to do that than to study how these marvelous structures work. ;D
Chill out
written by Rafael Grillo, April 13, 2008
Relax, please, everyone! It's amazing how aggressive some people can get just commenting on a great engineering feat that I am sure everyone -including the designers- know is not perfect. I'd guess everyone reading this article is here for a direct interest in improving the planet, and yet, everyone seems ready the rip everybody else's heads off. OK, perhaps that is a bit exaggerated, but no need to insult others. If you have a point, make it. If you a comment, post it. But please, keep it civil.

I designed the order cheap cialis turbines and it is true that some of you have a very limited knowledge about wind turbines and wind conditions in costal regions. Thanks to all of you who worte a comment and knew what they were talking about. The turbines are producing power, no it is not a waste of money and yes it is to some extend a wow effect but it will pay off. And by the way, there are more to come around the world. Once you made the first a lost of clients will follow, now that they have seen it is posible.
written by julius, September 08, 2008
if it is possible to erect smaller version of wind turbines (with small generators)in existing skyscrapers all around the world then it would reduce energy dependency in large scale... it can also be possible i think....... further this turbine technology need to part of common designs for the future skyscrapers too.........
i see this building everyday
written by clark, September 28, 2008
I see this building everyday on my way to office and never there was a chance that i didnt glance at it. Its pretty ambitious building with great pride and this building speaks for it self really something new everyday we get excited seeing this building being completed, however i just noticed that dust is this buildings worst enemy, here in bahrain a month is not complete without sand storm sometimes almost zero visibility, and i feel sorry for the spiderman cleaning those windows 40 to 50 degrees under the sun,imagine you just cleaned your living room and at your back you find your kid throwing things again a never ending story of cleaning.though BWTC is a good attempt to show to the world the ecological concerns that we have to deal today and bahrain is doin their part...

written by Sarah, November 03, 2008
It's not a waste of money if the returns exceed the installation and manufacturing costs, and there is benefit in more than just the area of order viagra now finance and economic anyway. We have been trying to promote the sector of renewable energy for twenty years or more, and the fact that a site specific solution has been implemented can only act as a booster for the sector. Yes it may have come about as some sort of 'wow' factor, and yes it has been imlemented in an arab state as a result of higher levels of available funding, but surely the fact that this has occurred in a nation where oil and what is viagra natural gas are the prime (only) sources of electricity generation serves as a strong message. Never mind the driver that Bahrain will soon lose it's status as a net exporter of oil :P They may not be huge wind turbines, but the slightly lower mean annual wind speed in Bahrain of brand levitra for sale about 4.7 m/s makes it more efficient to implement small scale wind turbines that provide elctricity at the site, rather than feeding not particularly grid compliant electricity into the low price cialis network. It's not about the size boys, it's about being suitable for the application. And as for varying wind speeds and direction, it's taken into account during design, where estmated installed capacity is derived using statistics and long term wind data. I'm afraid most renewable sources are more appropriate at distribution rather than transmission level, which is the way forward. This design will help make people sit up and take notice, which is what our sector needs.

Each to his own, I guess. I think the structure is a wonderful piece of architecture. And the turbines is a brilliant idea. Kudos to larsthor!
Why aren't they used?
written by Steve, November 29, 2008
I've been in Bahrain for 6 months. I don't drive by the building every day, but I have yet to see the turbines spinning. All of the conversation is interesting, but if the turbines aren't used, they just look a bit silly hanging there. Does anyone know if the turbines are being used? If not, why not? Lots of bluster - not much reality?
A change for the better
written by nhi, March 28, 2009
The building speaks for itself. The fact that it still exist has proved that there is no harm causes by the wind. Everything was calculated.

Sorry to say that but you're wrong...

1- It's true that Bahrain is very rich in solar energy. but it's rich too in heat.. and heat isn't a friend of solar cells... solar cells are designed more for temps around 25 - 30 ( they are rated at 25 in 90% of cases ) any more temps will decrease the effecienty of these cells and lower thier life too. If you didn't life in bahrain I'll just till you it can reach up to 50 here in summer, and even 55 in the hotest months of July/August. any object facing the sun directly without proper cooling can reach temps up to 60 - 65 if not more... just days from now, a qatary woman ( qatar is very close to bahrain ) fried an egg in 1 hour by just putting it over a ceramic tile in the noon, so they have to cool these cells in order for them to work effective.. and cooling needs energy too..

2- As what you already saw in these pics.. Bahrain is dusty. so they will have to cope also with cleaning not just cooling !!

3- the turbines are facing north, and the Bahrain WTC building design funneling the wind towards the turbines so wind is stronger thier... the direction of wind is coming from north most of the year.. so this is the best direction for this application...

4- recently The Bahraini goverment dealed with some companies to do some researchs for renewable energies, they are looking for Wind, Solar Cells and Solar heat ( Sterling )... and this is for electricity generating to help the electrical grid here.
Performance better than expected
written by Cameron, March 12, 2012
I'm currently assessing the viability of building integrated wind. Turbines mounted on buildings is a true sight to behold and the BWTC has to be one of the most beautiful of these structures, but it's not only about beauty is it?! I'm glad to say that in the case of the BWTC, the turbines are put to good use. They were initially estimated to produce around 15% of the building's energy, but due to several reasons are now contributing an even greater percentage, reaching 40% at times. However, despite the good news, there are issues! The biggest one (in my personal opinion at least) is that any surplus energy cannot be exported to the grid, as this goes against the energy policy in Bahrain (God knows why and usefull link cialis 10mg anyone who has any insight on this, please get back to me). So, while there are energy savings as the building generates some of its own energy, there is some 'green-washing' as the turbines are either being shut off when they are producing more energy than the building requires (which is probably why you don't see them turning) or the energy is being shed in other unuseful ways - what a pity!
