The power density of ambient RF is very, very low, and nobody can put up a

A transmitter can supply many receivers. Lets say it's a TV transmitter
of 10kW and it's being picked up by 10,000 receivers each using -10W
(minus of course because the power is coming in). That's a surplus of
90kW.
There are two reasons this is kept secret. Safety as alluded to above is
one, Exxon Mobil is the other.
I don think Exxon cares about who is paying for power: consumers or transmission companies. But AT&T & Verizon would, if people starts drawing powers from cell signals.
