This is a quick post to let you know that the Bahrain World Trade Center has turned on all three of its huge wind turbines simultaneously. For a glimpse of the turbines in action, check out the video over the fold:
The three massive turbines, measuring 29 meters in diameter, are supported by bridges spanning between the complex’s two towers. Through its positioning and the unique aerodynamic design of the towers, the prevailing on-shore Gulf breeze is funneled into the path of the turbines, helping to create power generation efficiency.
The wind turbines will deliver approximately 11-15% of the energy needs of the building, or 1100 to 1300 megawatt-hours per year — enough to provide light in 300 homes for over a year.
SVS – Edmonds Wind Driven Turbo Ventilators is a unique product for industrial & warehouse ventilation which runs 365 days * 24 hrs without consuming electricity. We have got a number of installations across the country and are receiving repeat orders as a testimony to their success. We specialise in protection of the bearings from the harmful effects of fumes, oily smoke, dust, soot, etc. thus ensuring a longer life for the product. We have models HURRICANE 600 ( Size 600mm / 24″ ) and HURRICANE 900 ( Size 900mm / 36″ ) in vertical vane design being manufactured in India. Our HURRICANE model is a vertical vane ventilator and is a breakthrough product being manufactured in technical collaboration with M/s Edmonds Pty. Ltd., Australia. This product has a higher discharge capacity than spherical vane ventilators of the same size along with superior bearing protection as the bearing is placed outside the path of discharge air. This is the only product available in the Indian Market which has certifications for Resistance to Wind Load, Rain Water Leakage, Higher discharge against Spherical Vane Ventilators of the same size from independent Australian certification agencies.Competitive Advantages of the product* Thicker and superior material construction * Integrated bearing housing to protect bearing from contamination thus increasing its life. * Unique Variable angle elbow to counter roof slope angle thus prevent leakage through vanes. * Can be used in high dust, high fumes high particle content applications without fear of bearing jam. * A vast list of very satisfied customers and a large bank of installation experience. * 900mm is the largest size ventilator manufactured in India

Here is one more alternate for energy conservation; you can get the image of “Shrijee Wind Ventilator” on http://www.shrijee.com
the sizes available in 6″, 12″, 14″ , 16″, 22″, 24″ & 25″
Shrijee Heavy Projects Works Limited (SHPWL) has introduced and promoted wind ventilation as a ‘New Concept’ in India with the twin objectives of power conservation in places where power is available: and ventilation in places where power is not available. SHPWL has been the undisputed leader in the field of wind ventilation since inception having supplied more than 30000 ventilators to over 500 customers, representing every segment of the Indian industry.
Shrijee has engineered Wind Ventilators from the conceptual stages and ours is the only wind ventilator certified by Indian Institute of Technology-Bombay. Wind ventilators, as the name suggest, works on natural wind power and conserve electricity. Increase in wind velocity or temperature difference between the ambient & working environment increases exhaust through wind ventilators. Once installed, wind ventilators get rid of recurring electricity charges associated with conventional systems providing round-the-clock ventilation, are maintenance-free, and eliminate chances of electrical short circuits. They also save on labor required to operate conventional systems.
We have taken every care to ensure leak-proof installation to prevent seepage of water and entry of foreign particles to working environment. Our dedicated manufacturing facilities at Chennai with a capacity of 15000 wind ventilators per annum coupled with representation in every part of India ensure faster & reliable service.

Could’ve used magnets…
If the middle east is using these for energy – when they have all the oil in the world — they are certainly making MORE of a mockery out of the rest of the world, especially the USA.
how do they overcome the low frequency thump that occurs every time a blade tip passes an occupied floor? those sounds carry alot of energy and can really rattle walls and windows.
Both systems can fail. Unless you can reduce the area subjected to the wind, you must still contend with the forces the wind imparts on the blades.
Such controls are fine on a ridgetop somewhere but I think they would be insufficient when people are literally meters from the whirling blades.
or maybe they simply have brakes?
maybe they can rotate the blades?
So what kind of overspeed protection do they use? The nacelle seems to be fixed (from what I can see in the video) so they can’t turn the blades out of the wind. If they go out of controll, there will be blade fragments flying through windows with deadly effect. This seems a bit risky just to offset 10-15% of their energy needs. Solar is a much better choice for this application IMO.
