    Could all this activity be caused by a colission of some object into the sun? I'm just wondering if the sun got pounded by some asteroids a few weeks ago and they screwed up the balance of the surface, causing geyser-like effects.

    Highly unlikely. The heat from the Sun would vaporise anything long before impact.

    Flares (including this one) tend to be linked with sunspots which are relatively cool (emphasis on the relatively there) areas of the Sun. The Sun is made of plasma - super-hot electrically-charged particles. The plasma convects, transferring energy to the surface of the Sun. As the plasma moves it creates enormous magnetic fields. Normally these are confined within the body of the Sun, but occasionally, the magnetic flux extends beyond the surface of the Sun as an enormous loop. At each point where the line emerges and re-enters the Sun are a group of sunspots.

    Hot plasma streams along the line of flux, it usually confined to the magnetic flux, but occasionally it will break away as a so-called prominence.

    Flares are relatively common, but their cause is not yet understood (if any solar activity experts are hanging around - please feel free to step in right about now :)). From memory, the most well-regarded theory is that ever-increasing amounts of energy is stored in the magnetic fields of the sun spot. As the field becomes twisted and tangled, the energy continues to build until a point when the magnetic field snaps back into a less-tangled state. At that point an enormous amount of energy and plasma are blasted into space in a very short period of time.

    Mike.

    How about we send a bunch of satellites into LSO (low solar orbit), within the orbit of Mercury, with solar photocollectors powering their wait. When a flare does come by one or more of them, a large, diaphanous electromagnetic antennae are charged by the approaching particle storm, converting the power into electricity, which charges a laser array. The lasers fire from the "lucky" satellite into a power grid among all the satellites. The satellites nearest the Earth fire the power at a receiver on the Moon, which charges a gigantic battery bored beneath the surface. Over months or years, lower powered lasers send the power to collector platforms floating on the seas, which send electricity over cables to the electric grid on land.

    Sure, we'd have to wait years before a flare was captured. And it likely would destroy at least one of the satellites capturing it. But there would be several seconds during which the satellite could capture more joules of power than consumed since we invented fire. So after a patient wait, playing the odds, we'd win the solar lottery. If we started now, repurposing all that expensive, dead-end Star Wars spacewar technology, we might be ready by 2020.

    But its weight is a different matter entirely. Weight is a force, which means it should be measured in Newtons. Weight also requires the influence of a gravitational field. Since the Sun is in orbit around the center of the galaxy, and in free fall, it is weightless.

    (Well, actually, the Earth ''does'' pull on the sun some, so we can calculate its "weight" in the Earth's gravitational field independently of its "weight" in other gravitational fields... this is from memory, so it may not be completely accurate...

    All right, the sun weighs 3.6e28 Newtons. So there.

  36. Re:What X?? class would cook Earth by A55M0NKEY · · Score: 2, Informative
    Using the above scale, where X50 = 0.005 W/m^2 and the earth having total surface area of 509600000000000 m^2 ( half of which faces the sun ) I get the impact on the side of the earth facing the sun to be 1.25 * 10^12 = 1,250,000,000,000 Watts. 1,250 gigawatts. I read that a hurricane puts out up to 2*10^14 watts = 200,000,000,000,000 watts = 200,000 gigawatts. So it is much less powerful than a hurricane. Though the magnetosphere is much bigger than the surface area of the earth. I don't know how big.

    The earth is 6,378,100 meters radius 2 * pi * r^2 = surface area of magnetosphere facing the sun ( 6.3781 * 10^7 )^2 = 36 * 10^14 * pi * 2 = 4.52 * 10^16 watts = 45,200,000,000,000,000 = 45,200,000 gigawatts Much bigger than a hurricane, but spread out more.

  37. "Safe" solar power my ass... by Radical+Moderate · · Score: 2, Funny

    Guess this will put the kibosh on all those tree-huggers advocating solar as safe and benign.

    Let's face it, it's time to shut down the sun before it kills us and step up use of safe energy sources like coal and oil. The sun has had its chance, and it blew it.

  38. net power by Doc+Ruby · · Score: 2, Interesting

    The satellites only have to work *once* to have a net power benefit. The power in a single flare is vast compared to the total power consumption of producing, launching and monitoring a network of even hundreds of satellites. If the Earth were as close to the Sun as I propose the satellite orbit, it would be fried by a flare; the energy released making the satellites here on the Earth hardly makes a ripple in the ecosystem.

    The satellite lifetime is like the Star Wars "Brilliant Pebbles" tech: while the satellite is destroyed by the wave of energy passing through it, it lasts long enough to convert some power to a laser. The laser transfers power to a receiver a distance/direction away that is unaffected by the large power passing through the satellite, but even the fraction received is large. In Star Wars, the destroying energy comes from a nuclear blast, and the receiver is a military target on Earth. With the solar wind web, the destroying energy comes from a solar flare, and the receiver is a prepared target on the Moon.

    Some of the captured energy is used to make and launch replacements for satellites destroyed by the flare. Or not - even a significant fraction of a flare's energy would put us in an energy budget environment that makes today's tech look like rubbing sticks together.

    Solar wind power is better than Titanic petrochemicals for many reasons, mainly the superior efficiency of sending energy across the solar system in an "inertialess" laser, instead of bound up in matter. Then there's the reduced pollution of capturing and processing the laser energy, as opposed to burning chemicals to go out, retrieve, ship back, and process Titanic chemicals. And the pollution issue is relevant not just on the Earth side, but possibly on the Titanic side: maybe there's some kind of life brewing in that ocean. Probably not, but why ruin it for the possibility of human farming sometime in the future? The kind of life that might be affected by depriving it of a small fraction of the power of a sporadic solar flare is too different from us to consider, when compared to finding a cleaner way out of our approaching energy bottlenecks. Plus, we could siphon all these Star Wars scientists away from war development, into the more secure and profitable plentiful-energy business.

  39. I'll get modded down, but it's worth it by dswensen · · Score: 2, Funny

    I don't want to start a holy war here, but what is the deal with you SUV fanatics? I've been sitting here at my freelance gig in an SUV (Vortec 4800 V8 engine with 285 horsepower) for about 20 minutes now while it attempts to create a level 17 solar flare. 20 minutes. At home, on my Volkswagen Bug running diesel, which by all standards should be a lot slower than this SUV, the same operation would take about 2 minutes. If that.

    I won't bore you with the laundry list of other problems that I've encountered while working on various SUVs, but suffice it to say there have been many, not the least of which is I've never seen a SUV that has run faster than its Rice-grinder counterpart, despite the SUVs' faster chip architecture. My six-disc in-dash CD changer and Bose speaker system runs faster than this 285 horsepower machine at times. From a productivity standpoint, I don't get how people can claim that the SUV is a superior machine.

    SUV addicts, flame me if you'd like, but I'd rather hear some intelligent reasons why anyone would choose to use a SUV over other faster, cheaper, more stable vehicles.
