Much like Wi-Fi for power, it has a transmitter feeds a laser, the beam is steered and kept on target by tracking hardware, and a receiver (essentially a compact opening plus a mirror that redirects light onto rugged solar cells) converts photons into usable current.

The power needed to generate lasers is huge.

So it will be 100 units of power in, to get 1 unit of power at the other end. Great for military use in a remote location, not so useful for 100 million US homes.

Does nobody have any imagination? The biggest solar energy farm is in the heavens, where unfiltered, limitless solar rays can be collected on the moon, and then beamed down narrowly to earth with this new method. There is your power. There is your high ground and direct line of fire. All that’s needed is the lunar power plant, the lasar projectors, and the terrestrial collection terminals. So we best get cracking, before the PRC beats us to it and monopolizes the moon.
