Space Ring Could Combat Global Warming 955
telstar writes "Though the debate continues around global warming, a new proposal suggests building an artificial space ring around the Earth to block the light of the sun and bring a balance to solar radiation, cloud cover, and heat-trapping greenhouse gases. The ring could be comprised of particles which would scatter the sunlight, or be built by an interconnected ring of spaceships aligned to block the light. The former proposal is estimated to cost anywhere from $6 trillion to $200 trillion dollars, while the spaceship solution would run approximately $500 billion. Halo fans rejoice."

It would actually costs less than an SUV, you'd just have to dump half the steel to cut weight, which would reduce its size significantly. I propose we call the result the "carr." Or something like that. I don't know. I'll leave that to marketing, but I'm gonna get my company on top of this. We'll make a fortune.

Of course, linux users are as chipper as ever due to the fact that they never seen natural light to begin with so they aren't as affected.

Now, let's orbit these solar cells at 500 km altitude, i.e. a diameter of 13,756.3 km or circumference of 43,217 km. The article doesn't say how wide the ring should be, but to block 1.6% of the sunlight to a circle 12,756.3 km in diameter would require a strip about 160 km wide. That's 6.9 million square kilometers of solar cells in the full ring.
Now the silicon wafer in a solar cell [wikipedia.org] is really quite thin, typically around 300 microns thick, so that's only 2.074 cubic kilometers of silicon all up. Density is 2330 kg/m3 [webelements.com], so that's 4,833 megatonnes of silicon required, or about 0.0000005% of the earth's resources. I think we have enough.
Of course, the energy required to manufacture that sort of area of solar cells would be pretty high, but think of the returns. The earth receives about 1370 W/m2 [rutgers.edu] in orbit, so multiply that by the area of cells facing the sun (2.04 million square km), and you get about 2.8 billion MW of incident radiation :-) Let's say these cells aren't particularly efficient, maybe 10%, plus transmission losses of another 70%, and you still have 84 million MW of usable energy, all day, every day.
Now, in 1997 we used 380 quadrillion BTUs [ecoworld.org], globally, or about 111 quadrillion watt-hours. That's an average consumption of 12 million MW, comfortably within our budget for some time. An energy-producing system with a capacity of 7 times the entire global requirements is worth quite a bit.
There's only one downside to this - if we divert all this energy down to earth & use it, it all ends up as heat in the end, which completely nullifies the original purpose of the ring (if you remember) of preventing global warming! D'oh!

I have it from a super-reliable source (George "Dubya" Bush) that there is no such thing as global warming. It is all a knee jerk, radical left wing fantasy designed to throttle the American economy (says he).
On the very miniscule chance that "Dubya" is wrong, what exactly is wrong with global warming, anyway? The neo-Con(artists) always look at the silver lining in that dark cloud - a longer growing season, less need for winter heating, new opportunities for real estate development (sea-walls, dikes, new ocean-front property, and vast new markets for SPF-1000 suntan lotion.

You claim that my use of the term "modest proposal" is unfounded. Of course, I never did say that it was the intention of the originator of the idea to use space rings to create a modest proposal. What I did say is that the article acts like a Modest Proposal, which causes people come out and say that it would be cheaper to curtail the introduction of carbon into the atmosphere than it would to implement such an absurd idea. Indeed, a cursory glance at the thread in response to the article reveals that this very point was raised at least a dozen times. Absurd schemes like the one presented in TFA have the effect of making people think of alternatives. This is an empirical truth, regardless of the author's intent.
So I'm right. You're wrong, either through willfull misinterpretation or crap reading comprehension. If you really want to see whose dick is bigger, I'll warn you: mine is.

trees would help cool the earth.
Yes, okay, and now for the science...
because they hold more water.
... Okay, not what I was expecting, but let's go with it...
trees also help water evaporate so there will be more rain.
But, I thought we were storing water, not helping it evaporate? There must be some logical reasoning behind this...
more rain = cooler weather.

What if we could alter the amount of solar radiation received and tailor it to our needs to make more of the planet inhabitable and comfortable.
More than that with a ship ring, we could get all the annoying people to crew the ring (or at least serve prison sentences on it).
