Wht they figured out is how to convert AC to DC and DC to AC at very high 
voltages and currents, with less loss than is caused by AC transmission.

AC transmission causes extra losses and needs far better insulation for a 
given average voltage rating, because of the peaks of the AC wave. They
are 
about 41% higher with AC than is required to transmit the same amount of 
power with DC, given the same amount of the same conductor in the cables.
