Because even 100 times wind power could compete with fusion, which is known to work we just haven't got it up and running yet.

Sweet. Now we can power this 60-watt light bulb!

Nice that this is about physical design and not use of exotic materials or something like that.

But I also want to think that the low pressure areas behind the blades of wind turbines have already been blamed for bird and bat deaths. So this design, which would cause larger areas of even lower pressure behind the turbines might get a lot of resistance from some environmental groups.

That being said, I keep thinking about buying a plot of land and using a windmill for limited power generation. So this is a nice step for my plans.

According to the story, if the new technology pans out we only have to cover an area a quarter of the size of Alaska to get all of our power from wind. That sounds feasible.

Granted, wind will useful in several areas as part of a complete energy policy, but you are going to need base load power, and you are going to lose an annoying percentage of power transmitting electricity from windy areas to areas that have people.

/My personal belief is there is a better than even chance that natural gas will provide a good portion of near-term power until liquid fluoride thorium reactors come online. Fusion may come online after mid-century -- the joke I heard is "Fusion is the energy of the future, and always will be!" -- but I'm not sure where the economics will be compared to LFTR, since thorium is cheap as dirt.

It appears that the breakthrough is done by surrounding a turbine with a "lens" aka ring that better directs the airflow/results in eddy currents. Somehow I don't think this will scale very well to the giant turbines used in most commercial windfarms. All of the pictures I've been able to find show it being used on smaller turbines, the type that an individual might own or might be placed in an urban area.

If this is the case a 2-3X efficiency is reasonable as smaller turbines are currently not that efficient. Large ones are though; so I don't see this being the boon the author thinks it is.

We don't build wind farms where there's no wind. Ever been out in a boat on the ocean? It's ALWAYS windy on the water, which is why we're looking at putting wind farm offshore, like the Europeans do.

loonatic112358: Ok, who ordered wind turbines from Dyson

Probably not too far off the mark, as Dyson is investing more into fan and turbine research than anyone else out there at the moment.

Don't people realize that wind power might blow the earth off its orbit?

FTFA: 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.

Found this interesting. Yes I understand about needing base load power.

Asa Phelps: that doesn't look like a standard wind turbine to me

The one is the photo is some sort of artist render and I'm not sure how the heck it would even work (I get the concept, but think that with friction/etc. it would be impractical). The actual turbines form the lab in Japan are more traditional looking.

Also, as I said before, none of the japanese prototypes are full size. I still think that this "lens" technique won't work well for large turbines (too much weight, wind loading etc.) but will likely be good for small turbines. I could see getting one for a country house.

Gee just what we need.....another idea for a very fragile and easily disrupted power generation and distribution scheme.

Why oh why arent we burying everything under meters of concrete and then under the footers of very large buildings?

A ring of fission reactors buried hundreds of feet down around a major city and manned by the marines would be about the most bullet proof grid you can imagine. When fusion becomes available you refit the underground stations one at a time.

In the extremely unlikely event of a melt down you let the damn thing melt through the floor and pour concrete down the hole till its full. Or you can use one of the melt-down proof designs that the Chinese are working on.

The point is that a big storm, volcanic eruption, river flooding, or even a war is not going to touch hardened deep shaft installations, and they dont need to be hundreds of miles from the customer.

This. There are times the wind is calm, therefore it is pointless to try and generate energy when the wind is not calm.

"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.

tinfoil-hat maggie: Found this interesting. Yes I understand about needing base load power.

Now that wind is very cheap, there will be a lot of pumped hydro to convert some of it to base load power (albeit with significant losses, but wind is becoming cheap enough that the losses are tolerable).

Frak them. Seriously. FRAK THEM says this progressive democrat.

Lead and other heavy metal toxic producing coal plants are doing much more damage to bird populations than windmills ever will. Hell, Interstate highways have their own problems.

At least this method gives them a chance, rather then poisons them before they hatch.


Most of the time it's not really environmental groups as much as it is that new environmental NIMBY group "concerned that their view....err..property value..uh.."bird population" might take a hit.

Many an ancient mariner would disagree with that assessment.

Additionally even Europeans are not aquatic. Meaning that putting windmills offshore requires transmission over not inconsequential distances. Transmission means lost energy. No way around that.

I mean it's cool and all that they came up with this new idea 5+ months ago but let's not lose our heads just yet.

If 1% of the wildest claims for new energy sources actually panned out as first described we'd have so much energy right now we'd have to pay companies not to overproduce and overwhelm our grid with endless amounts of free and clean electricity.

Or work with landowners over the great plains. Lots and lots of open crop fields, and turbines at set intervals won't take up much of a footprint.

Yes it's a huge public works project, but it's one that's needed. Our grid is practically the same one or grandfathers installed. Let's boost the current economy and at the same time make a major infrastructure investment that will grow private business in the future.

watson.t.hamster: Transmission means lost energy. No way around that.

Sure there is--raise the transmission voltage. Yes, I know, you still lose energy, but it's really very manageable. For example, a huge amount of the power we make up here with The Dalles Dam hops onto a high voltage DC line and heads directly to Los Angeles. That's way the hell farther than most offshore wind resources.
 
2012-01-10 12:50:25 AM
Oh looking into this I realize its pretty much BS. Large wind turbines (the type you see in new wind farms) are over 35% efficient in capturing the wind energy that flows through them. Thus it's pretty much impossible to increase their efficiency by 2-3X.

Also shrouded turbines aren't new and claims of a 2-4x increase have been made/proven before with them. It's just that it's turned out that its easier/cheaper to just make the turbine larger (longer blades) than to build a shroud. This is only really useful if you have limited space.

Nuclear energy becomes more expensive every year, solar and wind cost less every year. It's ridicules that the US government is subsidizing tens of billions in loans to the nuclear energy industry and practically nothing to solar and wind.

If the government is to invest we should invest in clean energy that isn't going to cost more and more.

They've got some wind turbines now, you can see them from I-80.

Some people hate them and fight against the turbines, but other people (in the same area) often love it. Turns out that some of the haters are mainly hating because the situation is that they won't get one, so their neighbors will make money and they won't, just due to luck of location. Again, you can see 'em from the highway. Personally I like the look of wind turbines (even the old normal ones).

Then I thought to myself I wonder if someone made a similar map of the area taken up by every roof of every building in the country, what would that look like.

Slives: Nice that this is about physical design and not use of exotic materials or something like that.


I disagree and assert that, to scale it to their conceived full size, exotic materials will be required to support the shroud and efficiency compromised by larger supports interfering with wind flow.

It's a classic strength of materials problem: an ant looks incredibly strong - able to lift and carry many times its own weight - but would be crushed by its own chitinous shell if it were scaled up to the size of a horse. This turbine design works really well on a small turbine in the lab, but to scale it up to commercial wind farm size is quite a different problem.
