What about wireless electricity? https://teslasciencecenter.org/teslas-wireless-power/ We know that wireless Wi-Fi and Bluetooth work and carry electric signals. Wouldn't it be possible to send electricity wirelessly?
You can send power without wires, over short distances. Induction charging on devices like iPhones and Apple Watches are common examples of that.
But it gets exponentially more difficult to transmit power wirelessly, the greater the distance between the receiver and the transmitter, especially if you want to send large amounts of power that way. Certain bands of radio waves can be transmitted long distances, and could b turned back into electrical power on the remote end.
But by then you will have successfully converted a multi-kilowatt power source into the source antenna into a few microwatts at the receiver. Not very efficient.

it is extremely inefficient the larger the distance. It's already not greit when a phone is sitting literally millimeters from a wireless charger
