 power all across the country at very high rates of efficiency at between 350 and over a million volts and then they then they step it down at the other end and this high voltage is great for sending lots of power long distances with very very low efficiency losses but it's an achilles heel when it comes to a solar storm or an emp and so those achilles heels did not exist the last time a big storm like this hit our planet so we're just like totally unprepared
