There is massive losses in the transmission of energy by means of though air or vacuum, there is nothing great about it, it’s inefficient, it can be done, I have made steel wool sparkle up by using a Klystron aimed at it across the workshop, but frequency was 27 GHz and 2 Watts of power, the efficiency was around 12% . Sometimes I wonder why I am still alive with some of the dumb and dangerous crap I used to do. Now to go and push a fork into the power point.

Even thick copper cable has resistance.
