Grimshaw Aerogenerator: A Colossal Wind Turbine

aerogenerator

We saw, not so long ago, how the Dutch are trying to bring a different aesthetic to wind generation by ditching the single stem support in favour of "wind trees." Now a radically different slant on viagra delivered on saturday by fedex the look there united healthcare cialis idea of generating energy from the wind comes from Nicholas Grimshaw Architects, designers of best places to buy viagra the "Biome" domes at the Eden Project in Cornwall.

In the UK, there is a target to meet 10% of the nations energy needs by 2010, at the moment, this target is on shaky foundations as the hoards of "Not In My Back Yard" protesters try and generic viagra online halt the progress of clean, green, generation. No sooner is a wind farm proposed, than a local action group voicing the concerns of the vociferous minority is also founded.

All of these arguments begin to make far-off-shore wind look like the women cialis sensible option, and Grimshaw has come up with a pioneering solution that looks the part for a new era of the "white heat of sustainable technology" that we are entering into.

Unlike the three bladed turbines that we have come to viagra in australia for sale know which spin on a horizontal axis, the gargantuan Aerogenerator spins on a vertical axis. It looks more like a gigantic television antennae than a turbine and, when moving, I imagine confused boatmen thinking they may have stumbled upon a secret government teleportation project.  And it will be huge, yes...that is a battleship in the background...for scale.

Here's a 1024 x 768 wallpaper version of tramadol no prescription fedex the grimshaw aerogenerator we made, if you're interested.

More after the jump 

Spinning at three revolutions a minute, the Aerogenerator could generate around nine megawatts, a massive amount compared to the average of around two megawatts we have come to expect from horizontal turbines. Because of the larger power output, it would be more economical to build out at sea.

The design is derived from the Darrius style of turbine, which rotates on a vertical axis – and as such is omni directional, accepting wind from whichever direction – not requiring a vane to cock the turbine into the wind. 

There is also the potential with this design to harness the power of the waves and tides by sub-surface generators.

If all goes well, we could see these generators in three to five years.

All in all, the Aerogenerator looks to be an iconic design, which if proven, could be a familiar and welcome sight to our coastlines.

I was talking to a representative of the offshore wind farm at Scoby Sands, Gt Yarmouth and I said at least you didn't get lots objections, as it is at sea.
He laughed and listed all the various groups that had objections. So it seems you get still get Nimby objectors, even at sea!!

That Grimshaw generator is one massive bit of kit, although the output seems low for the size. But apparently vertical generators are inherently less efficient, with vibration and bearing problems.

Out at sea
written by Hank, September 10, 2006
It depends on how far out at sea the things are. They're discussing putting these generators so far out that they would hardly be specs on the horizon. That, I think, would put the nimbers to rest

I really think that we have yet to see the final, best design of how much viagra a wind generator. I think most of the criticism of the various designs is unreasonable though, given the cialis online pharmacy alternative is smog-creating power plants.

To big, to less energy generation, to ex
written by Marc, October 16, 2006
This Grimshaw giant is enormous. Even so enormous that it will be VERY expensive to manufacture and to build. And a capacity of 9 MW is compaired with the size of this thing very little. In contrary of what this artikel states, there are already several wind turbine generators with a capacity of 5 - 6 MW (Enercon, Repower, Vestas) and it is believed and non generic viagra very likely that in 2010 there will be wind turbines of 10 MW. This wind turbines are way smaller than this Grimshaw, 125m tower and 125m rotor diameter. So these are very much more economical than this Grimshaw fantasy.

colour

perhaps if wind gens were a less visable colour? like green for land,blue for ocean or even camoflaged instead of original viagra stark white,a colour more suited to http://www.diabetes.org.br/free-cialis arctic backgrounds.

Looking at the micro instead
written by Joe ellsworth, March 31, 2007
Why Micro? Because it a large fraction of the cost of electricity is cialis online switzerland delivering it to the point of consumption. If you can use local turbines to eliminate some of this load then the grid and other infrastructure related investment can drop. The other is the micro approach when effectively designed allows use by a larger group of people who would be unwilling to tackle larger projects.

The Mega scale units are ideal to provide municipal scale power but there is still going to be an issue of matching loads for consumption to peak production. Readily adoptable micro designs will help especially if used for direct cooling which allows for easy storage.

We have been building micro level turbines originally modeled on buy cheap tramadol online inurl high pressure blowers. They use many of viagra overnite the same physics as Savonius type turbines but also have specially shaped wings to we use it best viagra take advantage of the air foil lift of the of the Darrieus type machine.

We choose a horizontal mounting mechanism so we could keep the turbine blade close to the roof (only 2 foot tall) what we have seen is a dramatic increase in wind speed caused by the funneling of air over pitched roofs being squeezed between the roof and the where can i buy viagra horizontal wind being accelerated via the Venturi effect. This design is more difficult to aim but in most mountain canyon and coastal environments the wind tends to blow in two predictable directions which reverse once per day.

Our use was is predominantly to operate a mechanical compressive chiller intended to be installed in areas where there is no electricity available. As a result we where looking to maximize torque over speed which this design seems to levitra generico do quite well. We use a centrifuge force model that allows the system to turn with zero loads at low speeds and starts transferring ever larger amounts of force into the compressive chiller as speed ramps up which also provides automatic speed management. On a larger scale it looks like it could chill sufficient water to cool most 2 and 3 story buildings at least in areas with at least 4 to 5 hours of 9MPH wind per day.

Our first product target is a 5 cubic foot freezer that is entirely wind powered and can be installed in under 4 hours by the average handyman and viagra online pharmacy usa which will easily withstand 100MPH winds. This is an example of generic levitra canada the micro versus the macro. I think there is a need for both but wide spread adoption of the micro may help acceptance of the macro scale units. Its main market will be providing a limited amount of chilling to keep perishable foods safe during the 96 hours of power loss caused by common hurricanes as a result it has to withstand the levitra online no prescription hurricane and keep on working.

An Even Larger Darrieus Wind Turbine
written by Flea Bunker, March 24, 2009
I like this idea, but I found a blog that advocates large machines that don't necessarily have large components like this one does. I think maybe the Aerogenerator idea can be combined with the ideas in this blog post:

I was pondering buying these wind turbines. Its been a dream of mine and was wondering if anyone could help me out or point me in the right direction. thanks Zack
