Sure, it wouldn't be practical to have a huge propeller-type blade.Even a cross-flow fan is subject to the square-cube law, although you could indeed scale it up in one dimension without increasing the mass per square foot of wind capture area.
{china} own{s} most of our debt, holding our economy hostage too.
We got pwned?
A Japanese trader in the minerals said Tuesday that customs agents were still not allowing shipments of rare earths to Japan. Traders here say that it would be extremely difficult to find other sources of the minerals if shipments continue to be held up. China mines 93 percent of the world’s rare earth minerals, which can sell for hundreds of dollars a pound.
...
Rare earths are used to make a range of products: glass, batteries, compact fluorescent bulbs and computer display screens. Demand has risen in the last decade for their use in clean energy technology, like generators for large wind turbines and lightweight electric motors for cars.
They have been crucial as Japanese automakers vie to keep the lead in fuel-efficient vehicles, turning to the minerals for the powerful electric motors that help propel gasoline-electric hybrids like the Toyota Prius, or Nissan’s all-electric car, the Leaf.
i just read up a bit on another looming problem with hybrid cars. Rare earth minerals (http://en.wikipedia.org/wiki/Rare_earth_element#Technological_applications). China has a nearly 100% monopoly on them right now. They are essential ingredients in components/batteries of hybrids. Also essential part of manufacturing of tech in general.Since they could be mined and produced in many other places, including the U.S., though, it's great that they decided to do this, and wake up the world now, instead of at a later time when it could have dealt a serious blow to U.S. strategic capabilities.
In short: buy oil and support terrorists; buy hybrids and support chinese communists. Both of whom are anti-democracy, and both of whom would like nothing better than to see america and western europe utterly destroyed.
The main objection to nuclear right now is plain cost. It's more expensive than coal (which, by the way, also generates a lot of radioactive waste, but that just goes in the air instead of being stored) and gas, one because reactors are pretty expensive to build, and two, because the red tape involved for anything nuclear is astounding. I expect both objections to go away in the next decade or two because coal and gas are just not going to stay this cheap. That would also make other "clean" energy sources more competitive, but I suspect we're going to have to start taking nuclear much more seriously than we've done up till now (excepting the French and a few other countries).
Thorium doesn't require enrichment.I think that Thorium breeder reactors are a good idea, but I'm afraid this is one claim that can't be made in their favor.

Military officials are only now conducting an inventory of where and how U.S. suppliers use the obscure but essential substances -- including those that silence the whoosh of Boeing Co. helicopter blades, direct Raytheon Co. missiles and target guns in General Dynamics Corp. tanks.
Warning Signs
“The Pentagon has been incredibly negligent,” said Peter Leitner, who was a senior strategic trade adviser at the Defense Department from 1986 to 2007. “There are plenty of early warning signs that China will use its leverage over these materials as a weapon.”
Deng’s Quotation
In the lobby of Bai’s company, a unit of state-owned Baotou Iron & Steel Group Co., a now-famous 1992 quotation by Deng is emblazoned in pink marble. It reads: “The Middle East has oil, and China has rare earths.”

Peter: I'm looking for some toilet training books.
Salesman: We have the popular 'everybody poops", or the less popular 'nobody poops but you'.
Peter: Well, you see, we're catholic...
Salesman: Ah, then you'll want 'you're a naughty, naughty boy, and that's concentrated evil coming out the back of you'.
The Chinese and the Arab top brass are much too heavily invested in the West to want to see it go to hell. For the rest, you're probably right.
Looks like they played us at our own game. Why bother going to war when you can play mergers and acquisitions with countries instead of companies?
who would have thought that commies would be better at capitalism than capitalists... :(
but yea they're out to 'get us' alright, i have no doubt about that, in the long run. That includes western europe I'm sure.
Lol - and you laugh at 'conspiracy theorists'. You are one yourself if you think China is powerful enough to do that. No way in hell that could ever happen. The EU and North America are stronger and their economies are more sustainable in the long run than China's.
While the U.S. has been tied up in Iraq, China is modernizing its military and its air defenses are now nearly impenetrable to all but the newest of American fighters, the senior U.S. military official in Japan said.
...
In May, Air Force Secretary Michael Wynne said drastic action was needed.
"I'm concerned for the future," he said.
I guess I do, so does the pentagon (http://www.cbsnews.com/stories/2007/09/29/national/main3311230.shtml)for what its worth.
um, since when are we allies? You do know that china is the number 1 backer of pakistan, dont you? And north korea? And iran?
You do know that the US is allied with japan and by our treaty with japan we're committed to defend japan as china flexes its muscle with them? As our secretary of state pointed out in the aftermath of the fishing boat incident?
you do know we're committed to defend taiwan and that china desperately wants to reclaim taiwan?
you do know that we back south korea and china backs north korea? ANd they dont quite get along?
dude seriously, i'm not saying this to just be obnoxious (tho heck, its fun to be obnoxious with a self-proclaimed troll ;) but seriously read a freaking newspaper now and then...
as for china's ambitions... um, you do know that burma and north korea are client states, and that china curently has territorial disputes with mongolia, russia, india, vietnam, japan, tibet, taiwan, and a few other countries? Most of which it has already gone to war for? That they're building out bases in the indian ocean and in the south china sea? That they're building out bases in africa and building strong military relationships with client dictatorial regimes in southeast asia and africa and the middle east and elsewhere?
you do know that they supply and fund a variety of maoist 'insurgencies' across all these areas, particularly in south and se asia?
read...a...newspaper... The CPC's strategies are hardly limited to currency manipulation alone...
Nuclear energy is good. Nuclear waste is bad.
All thats changed is we now face a two-front war with the newly financially empowered commie regime and with a variety of islamist regimes with no end in sight. As Petraeus said in woodward's new book, our kids and our kids' kids will inherit these messes.
Let's not forget that China has fewer constraints on Capitalism than we do, which puts them much closer to the risk of crisis than us. I predict a crisis will hit them worse than ours in the near future.
Nothing is more satisfying than a good dump.
Now I know EXACTLY what you are thinking right now, but you are wrong. I stand by my assertion.
I think that wind energy would be a great idea, once they make it cost-effective and reliable. What I don't understand is why they make massive wind farms (http://www.bbc.co.uk/news/uk-england-kent-11395964) instead of making one monster size turbine.Just adding my own wind-chimes here ... putting the already-discussed engineering constraints aside, the One Big Fan simply isn't as efficient at energy capture because it actually has a greater impact at slowing the wind down. Sounds ridiculous, maybe, but it apparently could be a real problem (http://www.google.ca/search?hl=en&safe=off&biw=1899&bih=913&q=wind+turbines+change+weather). An analogy might be made with hydroelectric power: do you use a large number of little turbines placed all along the mountain river, or do you just use one big turbine instead? It might seem counterintuitive, but there's a fixed quantity of energy in the system; each turbine (big or small, top, bottom, middle, doesn't matter) will slow the rate of water flow. Try to take too much energy and the water won't flow at all. (Interestingly, the generators will actually try to spin faster/slower in symmetry with the electrical draw being made by the power grid. Hydro companies apparently partially compensate on-site by frequently changing water flows. Or they just fire up other power plants. Or re-route through different power exchanges.)
i just read up a bit on another looming problem ... Rare earth minerals (http://en.wikipedia.org/wiki/Rare_earth_element#Technological_applications). China has a nearly 100% monopoly on them right now. They are essential ...lol ... Correct: China currently monopolizes world production of rare earths. Correct: rare earths are critical materials used in many technologies.
Nothing is more satisfying than a good dump.I don't know. Trying to read hexadecimal and disassemble it by hand can be a lot of bother. Avoiding the need for a core dump is more satisfying.
That energy gained through wind farms is not available when it's needed is outdated information
You could put homeless people to work in the [strike]salt[/strike] uranium mines (a nice warm place for them to stay).Of course, that's a joke, but this reminds me: isn't it better to have a few well-paid volunteers in the uranium mines than to have to poison the economy so as to force lots and lots of people to work in coal mines?
The winter before last (2008/9) the UK's wind farms ground to a halt for two weeks (http://www.telegraph.co.uk/earth/energy/windpower/4208940/Wind-energy-supply-dips-during-cold-snap.html), when their output was most needed.
Of course, you can guess the environmentalists response - wait for it - they blamed global warming for the UKs declining wind!!!!!! Bwahahahaha. You couldn't make it up.

Wind-power can be reliable in some parts of world but not all, which is a issue. Nuclear can work just about everywhere, atleast if you have solid ground...
Realy, you don't need even that, off-shore floating plants would work too...

What about in Iran?

You said "That energy gained through wind farms is not available when it's needed is outdated information." I gave a specific example that disproved your claim.
You are saying that the problems will be resolved. That is an assumption.
dont the dutch generate electricity from the tides underwater along the beach (or something)?
(i mean in addition to their windmills)
I wonder when the complainers are going to start *****ing about the "noise" generated by underwater turbines?
coal and hydroelectric still make up the majority of the worlds electricity
Wow, you necroed a thread from back when your fellow Troll Welly was still here.

Sorry. I'm an ignorant American who knows nothing about when is or isn't the proper time to necro a thread. I DO know that some people unfamiliar with the English language find the term "necro" offensive though.

I think there is nothing wrong with nuclear power.I think that the failure to use thorium in addition to uranium, or even more specifically, the failure to use Th-232 and U-238 in addition to U-235, is definitely a problem.
The problem is the usage of uranium instead of thorium.
Let's not forget that China has fewer constraints on Capitalism than we do, which puts them much closer to the risk of crisis than us. I predict a crisis will hit them worse than ours in the near future.
But everything we're discussing is merely conjecture anyway :D
The greatest crisis which could face China's capitalism would be America withdrawing the money/materials which fuel Chinese industry and the consumers who demand cheap Chinese products. Not that it matters much, there's plenty of other nations to support Chinese productivity, starting with North Korea, the rest of Asia, the (former) USSR, and the Euros.
Hmmm.....damn, one of those times I wish I wasn't always right.
iMav needs to include the time stamp in Vbulletin Quote HTML to make them more useful for "I Told You So"s, otherwise the pain of ZULU Military Time wasn't worth it.
Right that things could get much worse very quickly.
I posted it when it was level 4. Now it is a level 6.
BIG difference.
Damn, I'm good.
Threat Level 7.
