Japanese breakthrough will make wind power cheaper than nuclear

A surprising aerodynamic innovation in wind turbine design called the 'wind lens' could triple the output of a typical wind turbine, making it less costly than nuclear power.

Mon, Aug 29 2011 at 1:47 AM EST
 406

Snapshot from video
NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. 
 
The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential.
 
Let's say we developed just 20 percent of those wind resources — 170,000 square miles (440,000 km2) or an area roughly 1/4 the size of Alaska — we could produce a whopping 8.7 billion megawatt hours of electricity each year (based on a theoretical conversion of six 1.5 MW turbines per km2 and an average output of 25 percent. (1.5 MW x 365 days x 24 hrs x 25% = 3,285 MWh's).
 
The United States uses about 26.6 billion MWh's, so at the above rate we could satisfy a full one-third of our total annual energy needs. (Of course, this assumes the concurrent deployment of a nationwide Smart Grid that could store and disburse the variable sources of wind power as needed using a variety of technologies — gas or coal peaking, utility scale storage via batteries or fly-wheels, etc).
 
Now what if a breakthrough came along that potentially tripled the energy output of those turbines? You see where I'm going. We could in theory supply the TOTAL annual energy needs of the U.S. simply by exploiting 20 percent of our available wind resources.
 
Well, such a breakthrough has been made, and it's called the "wind lens." 
 

 
Imagine: no more dirty coal power, no more mining deaths, no more nuclear disasters, no more polluted aquifers as a result of fracking. Our entire society powered by the quiet "woosh" of a wind turbine. Kyushu University's wind lens turbine is one example of the many innovations happening right now that could in the near future make this utopian vision a reality.
 
Yes, it's a heck of a lot of wind turbines (about 2,640,000) but the U.S. with its endless miles of prairie and agricultural land is one of the few nations that could actually deploy such a network of wind turbines without disrupting the current productivity of the land (Russia and China also come to mind). It would also be a win-win for states in the highest wind area — the Midwest — which has been hard hit by the recession. And think of the millions upon millions of jobs that would be created building a 21st century energy distribution system free of the shackles of ever-diminishing fossil fuel supplies. 
 
It's also important to point out that growth in wind power capacity is perfectly symbiotic with projected growth in electric vehicles. EV battery packs can soak up wind power produced during the night, helping to equalize the curve of daytime energy demand. So the controversial investment currently being entertained by President Obama to pipe oil down from the Canadian Tar Sands would — in my utopian vision — be a moot point.
 
It is indeed a lofty vision, but the technology we need is now in our reach. And think of the benefits of having our power production fed by a resource that is both free and unlimited. One downside often cited by advocates of coal and gas power is that wind turbines require a lot more maintenence than a typical coal or gas power plant. But in a lagging economy this might just be wind power's biggest upside — it will create lots and lots of permanent jobs, sparking a new cycle of economic growth in America.

BUT...... Seen the number of blades, the price of the turbine will be twice as high as a normal one. Besides, other have tried this long before and it did not work !

Just saw that article you are talking about last week. It was talking about this being used in the deserts in the middle east. Tall carbon fiber rods that moved with the wind and stored the energy generated in pods in the base.

Just keep stumbling around, maybe it will come up again.

Yea, it was like a white canvas tube/tent, and they were growing plants under it and using the convection to harvest a current. check out http://alt-e.blogspot.com/2004/11/solar-chimney-for-california.html

too bad we didn't get a clue and still don't.

and why would you ever want to shut down a nuclear power plant? im assuming that you have absolutely zero clue as to how a reactor operates, have no knowledge of nuclear engineering, and have no idea what kind of safety protocols exist that govern how a plant runs. until you go to school and really learn about it, then you should keep your mouth shut and let the people who have gotten the degrees determine the fate of the plants, not the ignorant public.

Other than a brief mention of noise being a problem with wind turbines, in general, they failed to talk about noise, vibration of this new design. Hopefully, sound & vibration can be compatible with the enjoyment of all living creatures. It is extremely important.

Sorry in advance, but someone has to say it; most of these posts are half-baked with poorly thought out ideas, and half-brained notions of how energy is generated, stored, and distributed. Furthermore, the oversimplification of the economics of energy in an article like this just serves to make any discussion about it meaningless. It just goes to show you that one-sided thinking is absolutely bad (whatever faction you come from) and that meaningful discussion only happens when many points of.... More

I thought wind power was a great idea... Until I understood that on the hottest day in America, the winds were silent. Good luck with that, there isn't enough storage to make up for a 75% + drop in generation on the peak demand days.

Ignorance is truly bliss.....I aplaud the technology for wid power and certainly agree with its POTENTIAL, just as i believe tidal power, magnetics, and geothermal areas are all 99% unused. And then there is fusion which is nearly unmentioned anymore. However, we are not any where near "dwindling" in our supply of fossil fuels, jobs are made by desires for products and services, and nuclear waste (for my highly uninformed friend) is actually radiated microscopic materials in water for the most....

There is no end to the ways we can harness wind energy. Your article is clearly out of date. Did you spend more than 5 seconds researching the subject?

There is only one windmill solution for the planet: A planet sized windmill. Two pivot points, one at each pole and one blade that circumnavigates the globe. It would take 24 hours for one revolution, but the power generated would be incredible. Now, that's a crazy idea!

The author's note that current technology in wind turbine design is more cost effective than coal is just an outright lie. Since this author has a bias towards any "green" technology it's only expected that he would fall for any set of manipulated numbers to prove a point. The truth is that most Americans want uninterrupted power at the cheapest price possible and if wind power could do that we'd be all over it.

The unfortunate truth is that much of the world is, without damaging technology, unliveable in.
It's insanity to live somewhere that needs constant air conditioning ...and to compound that by relying upon technologies that could one day soon prove too costly or burdensome to provide that energy.
Sure we could use nuclear power, but eventually, and a lot sooner than you think, the waste products will start to become a burden. Not to mention the cost of the fuel, and the potential.... More

Also, where is all this land? Are you going to destroy national parks and build huge windfarms? Or are you going to kick people out of their homes.

Maybe Colorado animals are less sensitive than California critters, but I think all the impacts we have on this little planet are going to effect something.

Actually, that wouldn't help too much, I'm afraid. Disrupting a vehicle's aerodynamic profile and adding additional drag-inducers would really hurt fuel economy when trying to get the vehicle up to speed - up past 40-45mph wind resistance becomes a really big issue, and at freeway speeds of up to 80... well, I dunno.

A possible solution would be to run the turbines off the vehicle's exhaust, much the same way a turbocharger is run; this might have the undesired effect of adding.... More

I'm all for alternative energy, but do the math... The U.S. has 9.83 million km2. If 2.2 km2 is suitable for wind harvesting, then that is just in between 1/4 and 1/5 of the WHOLE country! If you propose 2.63 million wind turbines, then that comes out to more than 1 turbine per square kilometer! Imagine a windturbine every 1000 meters from the Mississippi River to the Rocky Mountains!

The sad part of having each household on it's own power source is that the renewable energy people are more greedy than the oil and gas people. That's why it costs so much to install a personal/household solar or wind system on a house. If we can get the environmentalists to quit being so greedy we could all have affordable renewable energy.

I read some studies that show that birds aren't stupid and stay clear of the wind mills. Do you think a bird would really fly through a wind mill? Would you? Birds still would have plenty of space to fly around the windmills. Instead of killing some "stupid" birds (you know the ones that fly into your window) lets just kill the O-zone and all of earth. That sounds like a great idea. If you stupid hippies would stop your nonsense it would be great. THANKS

'Well, such a breakthrough has been made, and it's called the "wind lens." '

It's usually called a ducted fan.
http://en.wikipedia.org/wiki/Ducted_fan

And it doesn't mean you can get any more power *per square mile*. It just means you can use shorter blades on the turbine to get the same power. Whether the extra structure saves money isn't clear.
