By 2015, installed capacity of wind energy will have reached 10 GW or more and by 2020 Gansu is expected to have 20 GW of wind power in the Jiuquan corridor.

GLEN BOLTON'S wish has come true through the discovery of "whale power" by Dr. Fisher: He detected that the bumps on the humpback whales fins, called tubercles, increase the whales capabilities to make sharp turns. Wind tunnel tests have revealed that turbine blade edges with these tubercles will put out about 20% more power and create less noise. The first wind generator with this new blade design has been installed as a prototype.

I am a retired aeronautical engineer and have been enthusiastic about the
fact that wind power has finally caught on in a big way. I have thought that
there should be some further research and testing done to find one or more suitable alternate designs for large wind turbines.
With the amount of investment now going into the existing design there should be funds available to make some reasonable attempt to design large units that could take advantage of lower speed winds that exist at the lower levels on existing wind farms. I understand that wind velocity is of primary
importance, but larger slower moving turbines could concievably create a
sufficient amount of torque with the slower winds to produce a practical
amount of power that could be fed into the existing grid of the conventional
wind farm. I am working on a design that I believe might just fill the bill.

Is there anyone out there who is working on alternative large scale designs?
I am familiar with some of the vertical axis concepts, which dont seem to be
capable of competing with the propeller versions, but maybe there is an "out
of the box" design that could work.

I'm sure that all of the cold, hungry mouths in China will will work hard because they require more power and will help their country grow as a world leader in these emerging fields. Just look at what they've accomplished already, and, good for them! Good for all of the world, eventually, as these technologies do tend to spread around.

China has the brute force of the larger number of intelligent people, and we can expect a proportionate number of problem-solvers to population, and using the punchline of an old unfortunate joke making fun of linguistic challenges when speaking English, "Many hands make light work" will likely be a very huge awakening to America and the rest of the world when they've got their lights on, and we in the USA are still arguing about drilling offshore or not.
Oh, and they're holding the note on our lavish homes, too. How'd that happen? Ah... while we were sleeping...

It also seems to me that the Chinese people are still more familiar with a government that expects their participation as part of the solution, rather than one with more individuality and 'not in my backyard' concerns all the time. They seem to work together better, even if at the expense of some of their personal benefit. We seem to be more interested in 'American Idol' than the power source that makes those TV sets work in every room of the house. I'm not encouraging 'more government' (no way, too much already) but I am trying to encourage better cooperation, and a bit of a 'reality check' to those of us who work on the solutions, and getting through all of the bureacracy we already have.

Let's hope that they develop more earth-friendly methods for feeding the power needs of all of those mouths, because we all share the same atmosphere, and I'd rather see more wind power than any of the more-toxic solutions like anything burned.

Yeah, and they're also going to build orders of magnitude more coal fired capacity. Pretty sad situation if you ask me.

It's good to see the optimism and possibilities but setting low goals and blowing past them is not that impressive. China is still rapidly expanding coal power plant at an enormous rate and took over as the #1 CO2 emitter in 2007.

Well, if I remember correctly, China spent last winter in the dark because of power issues. It's in their interest to install as much wind as they can, as fast as possible.

The Chinese dragon is about to breath fire in the world of renewable energy.
They are hot on the mark when it comes to wind, solar and hydrogen and I predict they will become world leaders in these fields.

East and West needs to work together to find a way to solve our energy and pollution problems.

Mr. Stoyke,

Thanks for your reply to my comment. Using whale tubercles on the
wind turbine blades is certaintly, "out of the box" ! More power to them !
Is there any more information about the performance of the prototype?

Someone should try molding tip plates onto the blades to reduce tip losses
due to the tip vortex. Most new jet liners have sprouted winglets at the tips to increase lift and reduce drag. The large diameter propeller turbines
have rather large tip speeds, and efficiency might be improved by a suitable
tip plate extending both above and below the blade. Also, this should allow
a broader blade chord to be used in the high speed working area of the
prop. Maybe it would be too complex. Just a thought. GB

China is developing very fast. That is correct.

I need to say one thing about Co2.
China is actually working very hard to decrease emissions, and if I remember correct, then CO2/citizen is higher in US, and I am afrais that India will be the worst very soon.

About windmill energy in China

My oppinion is, that China should go for big ocean based windmills, instead of land based windmills. The impact on the environment is much lower at ocean based mills, and even that the cost is higher, the efficency is much better, as bigger windmills can be used.

This oppinion is not only regarding China. US and the rest of the world should also go for the Ocean based windmills.

Why is the cost so high for those mills ?
One of the reasons is, that the Ocean Foundation is very expensive.
That cost can be reduced very much, by using the correct suppliers.
F.ex. our company.
We specialize in lowering production cost for steel parts.

But .. it is up to the contractors to establish that.
They stil think, that quality and delivery is not stable in China.
For some parts it is correct, but if the ability to follow strictly up on an order, by being there, the story is different. China as manufactorer is abolutely ok, but it requires that a trusted person follows up on the production.

Best of regards

Even they are powering forthcoming Olympics in Beijing with 45 MW wind power from Vensys!

Glen Bolton,

American Superconductor and Westinghouse in conjunction with the U.S. Department of Energy are trying to engineer and design jumbo 10 megawatt turbines using superconductor technology that would make the wind turbines 66% lighter then current methods. the venture was announced october 2007.

I've read about Tubercles Technology as well. It's actually a lot better than +20%, because the technology works disproportionally better under low speed wind conditions. And those are the most common. I think +100% output in low wind speed areas will be possible, making previously expensive low wind regions very economical.

we should praise them when they are good ,that is the case in WIND ENERGY ,where they keep growing steadly for the last few years
may they keep growing years ahead to 200 000 MG OF WIND POWER

they prove themselves right ,they had just take over the USA as #1 WIND POWER generating country '
May they keep growing at the same rate that this past years!
