The main issue with that is the larger implications - believed electromagnetic spectrum limitations asidd why the hell bother acting like a gaslighting scooby doo villains if when there are so many other greater applications starting with mesh network radios that don't take power, just "we are the only ones allowed electronic targetting" let alone any hypothetical masteries to allow for optical rectennas without the limitations which keep them from obsoleting solar panels.

It stinks of a bluff and playing a parlor trick of early RFIDs as far larger than it is.
