I think as other have pointed out HVDC lines make it a possibility. I don't quite understand the point made in the video about "expensive infrastructure to convert AC to DC"... wouldn't solar farms be generating in DC? Is the infrastructure in order to get the voltage up? Couldn't I string enough solar panels to increase the voltage?
