NOMBEDES Posted January 17, 2014 Share Posted January 17, 2014 WIKI QUOTE: On September 1–2, 1859, the largest recorded geomagnetic storm occurred. Aurorae were seen around the world, even as far south as the Caribbean; those over the Rocky Mountains were so bright that their glow awoke gold miners, who began preparing breakfast because they thought it was morning.[3] People who happened to be awake in the northeastern US could read a newspaper by the aurora's light.[5] The aurora was visible as far from the poles as Cuba and Hawaii.[6] Telegraph systems all over Europe and North America failed, in some cases giving telegraph operators electric shocks.[7] Telegraph pylons threw sparks.[8] Some telegraph systems continued to send and receive messages despite having been disconnected from their power supplies. END) What action should we take to shield out expensive audio equipment? You have to admit that the next event of 1859 scale is overdue! Maybe we will not have to take any action because when the electrical grid goes down hard, there will be so much social disruption that preserving our audio systems for future use will be the least of our problems.

esldude Posted January 17, 2014 Share Posted January 17, 2014 Maybe we will not have to take any action because when the electrical grid goes down hard, there will be so much social disruption that preserving our audio systems for future use will be the least of our problems. Usually called the Carrington event. I think your last comment is the only one that would apply if that happens. I think the geomagnetic induced current is of course related to the length of the lines. You will definitely need to be disconnected from the grid. I believe shorter lengths of wire will pick up less of course so running locally from battery power might save your equipment. And NASA is working on a warning system to give 30 minutes lead time on such an event. So having something to monitor that and disconnect everything would work. Don't know how far along NASA is or the access you can get to their warning system. Now I ran across this little page with info on faraday cages. Where it might be more interesting is the table of results of various homebrew cages (like a metal trashcan) complete with ratings across many frequencies. Maybe those who believe EMI from computers is a sound quality issue could adapt it to shield the rest of their audio system from the resulting emissions.

Just because the Sun isn't out to get us doesn't mean it can't hurt us just the same. And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment

sandyk Posted January 17, 2014 Share Posted January 17, 2014 Are such events really so rare, or like the present global warming cycle, is sensationalist media reporting rewriting the record books ? Surely the thermometers used back in the days of the attached report weren't so wildly inaccurate, or those taking the recordings so dumb that they put them out in direct sunlight hot enough to cook an egg on a shovel ? http://joannenova.com.au/2012/11/extreme-heat-in-1896-panic-stricken-people-fled-the-outback-on-special-trains-as-hundreds-die/ How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

I hope Wireworld, Straight Wire, etc., etc. take this in account for their future cable designs. Everything mentioned in Nombedes wiki quote is possible since our solar system is in continue developing (as digital audio), but I'm more scare about some politicians decisions...! Happy listening!

mayhem13 Posted January 17, 2014 Share Posted January 17, 2014 We had a taste of this in the northeast in 2003. Severe damage to the power grid caused by red tape and greed. One of the main grids was supposed to go off line due to the warnings of impeding solar flares but refused to concede the revenue. When the brunt of the storm hit the US/Canadian border, extensive damage was caused from the northeast to the northern Midwest. Hopefully we do get a warning and it's heeded this time. I don't think satellites will survive it though plummeting the worlds communications.....equally dangerous as it would take years to restore. Which begs the question if there's replacement sats and enough rockets ready to restore the network. Could you imagine no cell phones for a year?........I can, when I was 20 something. Amazing how we got on so well without being connected all the time. Link to comment

(grin) Seriously, short of a nuclear war, alien invasion, or massive solar flare, I think most such power interruptions will be inconvenient, annoying, and a little dangerous - but not of terrific consequence or of a very long duration. In the event of any of those three happenings named above however, all bets are - most definitely! - off. I could be wrong, so stash those generators and a few thousand gallons of fuel, just in case... -Paul A big power loss event is bound to happen some day.

NOMBEDES Posted January 18, 2014 Author Share Posted January 18, 2014 I always thought that EMP would fry all transistor electronic devices. Russian Aircraft used tubes in critical electronics so that the system could be reset and put back into service. So your generator would not work because the power management system would be damaged, but since not much in the house would run anyway, you would not need the power. I guess the EEs could hook up your tube amp to the generator and get a light bulb to work. The washer, dryer, dishwasher, oven, computer, and refrigerator, TV etc would still not work.
