I wasn't really the one talking about 5G radios, as much as they already have proven powerful enough to cause small birds to internally rupture, I was thinking of directed energy weapons that are specially designed precisely to focus such beams, for the express purpose of causing metallic materials to heat up.

I'm talking about the kind of power level, at a burst, that you find inside a domestic microwave, contained to an area of similar size. This is quite easy to do, and I'm sure there is probably dozens if not hundreds of devices floating above us in low orbit with this capability (via a small nuclear reactor and large capacitor).
