It’s not even remotely the same as charging something with microwaves. The power delivered decreases exponentially with distance. I’m sure you’ve heard the phrase “inverse square law”. Because you divide the effect and gain by 4pi(r^2) meaning your output is decreased by 75% every time you double the distance. You’re going to need ridiculously powerful hardware and an enormous amount of electricity to run it on any meaningful distance. linkfedilink
