Is a 'Katrina-Like' Space Storm Brewing? 356
pilsner.urquell writes "A newly released NASA report warns that the world has forgotten the power of the sun, creating a technological society susceptible like never before to large infrastructure damage from solar storms.
According to the report, the world has grown so dependent on modern technologies without respect of what the sun can and has done, that it's risking major communications, finance, transportation, government and even emergency services disruptions."

It wouldn't. The damage isn't from the particle cloud itself, it's from the ripples it sets up in the Earth's magnetosphere. This makes the magnetic field move relative to any conductors (like power lines and circuit traces) in it. That causes an electric current to be induced in the conductor. The atmosphere doesn't affect the magnetic field at all, so it won't provide any protection from the disturbance.

Drinking your own urine doesn't actually help you all that much. Since the saline concentration of your pee matches pretty well what's already in your blood, all you're doing is retaining the same salt that your body is trying to get rid of.
Recently, urine drinkage was disadvised by survival experts.

Please check the NOAA solar storm warning levels. They explain how far back to the stone age we will go when a big (X level solar flare) is going to hit the Earth.

On the communications. It is not just satellite communications that will get disrupted. But also HF, UHF and other type of communication. Your GSM (2G or 3G really doesn't matter) might work, but then it might not work. It is any body's guess.
People might be out of power for days or weeks in the worst case.

Are they safe from solar storms? Yes. If a solar storm strong enough to fry your CDs hits, your main concerns will be finding oxygen to breathe, keeping your DNA in one piece, and should you tell your doctor about the annoying way you glow in the dark.
Note, however, that CDs naturally degrade over a period of from 3-20 years depending on the brand. So there's a good chance they won't survive until the next solar maximum anyway. But don't blame the sun.

Once a surge protector trips, its off until its manually reset.
Not necessarily. Many simple surge protectors just use a couple of varistors and gas discharge tubes connected between the wires. These devices have a variable resistance that is extremely high during normal operation but decreases sharply above a certain threshold voltage, and thus provide a short-circuit path for excess current to take. After the voltage returns to the rated level, the resistance again becomes extremely high, cutting off the short-circuit.
You are probably confusing surge protectors with circuit breakers. The latter are far too slow to protect sensitive electronics from damage from a voltage surge.

Modern power lines aren't protected at all. They are naked steel cables. Of course that also means that they are unlikely to be damaged unless actually heated red-hot, but the transformers ? Each and every one of them will get the equivalent of a lightning strike simultaneously.
Transformers and substations have a considerable number of lightning and overvoltage countermeasures. Circuit breakers, arc chutes, etc. Maybe all transformers on the planet will go boom anyway, but there is significant protection available now to the electricity infrastructure against a once in a millenia solar storm.

since I'm pretty sure there are surge protectors now that are good enough to protect things from lightning strikes on the power lines.
any company that claims this is bold face lying.
NOTHING can protect your computer from a direct lightning strike.
Hell your computer is dead if it's unplugged and sitting on the floor if a big strike nails the ground 200 feet away the EM pulse will pop most of the circuitry. I ahve seen laptops with burned traces on the motherboard that sat on a couch and the lightning struck the tree 50 feet away from the house.
If anyone or any thing states it can protect you from lightning, It is a complete bold faced lie.
A lightning strike is so high energy you cant begin to even understand it.

Emphasis mine. For those who have witnessed lightning strikes, still had their laptops work afterwards, and are wondering what Lumpy might be smoking - lightning strikes can vary considerably in strength. To use an analogy, a Volkswagen Beetle and a Bugatti Veyron are both cars.

Never suggest something is impossible to a scientist. It just encourages them. :)
But while a deep underground bunker and/or sufficiently engineered faraday cage would probably do the job just fine, I have to admit that for my computers it'd be a lot cheaper to stick with the offsite backups and storm insurance. :)
