Except that theory has no basis in reality.

Microwave ovens work by concentrating that energy into a very small space.

When is the last time you were cooked by radio waves?

Microwaves ARE radio waves.

We’ve known about the possibility of doing this for decades.

The NRL did a practical test of it in 2022 iirc.

Nothing. It’s non-ionizing radiation.

Microwaves ovens work by using extreme amounts of energy concentrated into a very small area.

Microwave beams for energy transmission are different.

We’ve known this since at least 1996 when the first paper talking about it was published.

The biggest obstacle for it is actually RFI.

Edit to add, and here’s a NASA paper from the 1980s talking about it
