The Underappreciated Risks of Severe Space Weather

circletimessquare notes a New Scientist piece calling attention to a recent study by the National Academy of Sciences, which attempts to raise awareness of the dangers of severe solar electromagnetic storms. "In 1859, amateur astronomer Richard Carrington noticed 'two patches of intensely bright and white light' near some sunspots. At the same time, Victorian era magnetometers went off the charts, stunning auroras were being viewed at the equator, and telegraph networks were disrupted — sparks flew from terminals and ignited telegraph paper on fire. It became known as the Carrington event, and the National Academy of Sciences worries about the impact of another such event today and the lack of awareness among officials. It would induce un-designed-for voltages in all high-voltage, long-distance power lines, and destroy transformers, as Quebec learned in 1989. Without electricity, water would stop flowing from the tap, gasoline would stop being pumped, and health care would cease after the emergency generators gave up the ghost after 72 hours. Replacing all of the transformers would take months, if not years. The paradox would be that underdeveloped countries would fare better than developed ones. Our only warning system is a satellite called the Advanced Composition Explorer, in solar orbit between the Sun and the Earth. It is 11 years old and past its planned lifespan. It might give us as much as 15 minutes of warning, and transformers might be able to be disconnected in time. But currently no country has such a contingency plan."

Pacemakers?

As a cyborg (literally, if technically) I have to wonder what such a solar electrical storm would do to implanted electronic medical devices, such as my pacemaker. Any knowledgeable insights? If this shuts down, I'm history in seconds.

Survivalism != isolationism

Last time a major TEOTWAWKI event was looming (Y2K), I described the threat to my father in great detail. His response: [shrug] "I'll throw another log on the fire and go back to my book." True enough, my folks' lives are pervaded by self-sufficiency, including extensive wood heat, well water and homegrown food. Society shuts down, they just spend a few minutes adjusting and carry on.

But ... you wouldn't guess that at a glance. They have elegantly integrated the survivalist mindset with modern conveniences, enjoying everything technology has to offer without worries of what to do if the grid shuts down indefinitely. Everything has a low-tech backup, preparations for self-sufficiency are ongoing and already in use.

You can live a "survivalist" lifestyle, and still be fully "wired". The two ways of life are not diametrically opposed.

I call bullshit...

Bullshit, FUD and fearmongering...

No power utility has enough spare distribution transformers on hand to replace all of them after they go. They are usually built to order and take 12 months or more to produce. So why don't you imagine a power outage that lasts for months or years across the entire Northeast United States and tell me how undramatic it is? No refrigeration, no gasoline for your car (no electric to pump it through pipelines or service stations), limited and rationed modern medicine, no pumped potable water, no water treatment plants, no HVAC systems, limited communications, etc, etc, etc.

In a case of a large scale power-system breakdown you don't go and try to bring it all back up all at once.
And you sure as hell don't sit on your ass crying, mourning the end of civilization and your X-box points.

Instead, teams of experienced technicians (you know... all those people with the various degrees in electrical engineering) start fixing the grid so that they can have parts of it running as soon as possible.
1 transformer, 2 transformers, 3 transformers, 4...
You lack the parts? Pillage the dead transformers. There is a PRETTY good chance you can take 2 or 3 dead ones and have 1 working in under 24 hours.
Fix the ones that CAN be fixed, leave the completely messed up ones for later replacement.
Don't have enough power to power the entire town cause the nation-wide system is down? DON'T.
Give one half of town 12 hours of power and then turn them off for the next 12 hours while the other half gets their 12 hours. Or 8. Or 6.

Hell... During the war (I'm from Bosnia) people used to steal cooling oil from the transformers (you can run chainsaws for cutting wood, and even cars on that stuff), artillery shells would explode next to them drilling them up with shrapnel, even the local power-plant got hit couple of times so bad that technicians had to take it off line to patch the pipes in the cooling towers.
Let me tell you... you get used to 4 hours of electricity per day (or less) VERY fast.
You leave the lights on to wake you up when it comes on.
Charge the batteries, cook, wash clothes, heat up the boiler and then go about your business waiting for better times.
