"Did you know a solar flare can make your toilet stop working?"

In a 132-page report from a NASA funded study, experts detail what might happen to our modern, high-tech society in the event of a “super solar flare.”

Ground currents induced during geomagnetic storms can actually melt the copper windings of transformers at the heart of many power distribution systems. Sprawling power lines act like antennas, picking up the currents and spreading the problem over a wide area. The most famous geomagnetic power outage happened during a space storm in March 1989 when six million people in Quebec lost power for 9 hours.

In 1859 the largest know solar flare triggered an explosion along electrified telegraph lines, shocking technicians and setting their telegraph papers on fire. If that same massive flare occurred today,

Power outages would be accompanied by radio blackouts and satellite malfunctions; telecommunications, GPS navigation, banking and finance, and transportation would all be affected. ... The total economic impact in the first year alone could reach $2 trillion, some 20 times greater than the costs of a Hurricane Katrina

Bottom Line

It's a good idea to have your computer, TV and any expensive electronics connected to a circuit breaker. This may protect them from power surges and nearby lightning strikes. But don't count on the breakers saving you from a monster solar flare; they will probably melt.
