There were, however, telegraph networks, and the long wires of the network in France became the antennae for solar energy, heating up transmitters, some of which caught on fire. 2 Today, the damage potential is far greater: communications satellites can be knocked out, astronauts have to take shelter in a special module in the space station, pipelines can be damaged, GPS systems harmed, flights re-routed, and potentially most damaging of all, the electrical grid could be knocked out across parts of North America for years.
