You don't need a wire. You could use a waveguide (which is a sort of tuned pipe) instead and squirt microwave power down it.
You could send microwave power straight through the air and that is perfectly safe except to anything living that gets in the way of the beam.
You can also transfer electricity along paths of ionised gas. Physicists call this "lightning".

it can also be accomplished by induction loops. if you ever notice on various waterproof shavers, they recharge just by sitting in a cradle with no electrical connection.
a generator works by rotating a magnet near a coil of wires. the same is tru in reverse. if you have a fluctuating magnetic field, a properly tuned coil of wires can convert that back into power

telsa was a strong proponent of wireless electric power mains. he demonstrated with VLF emf waves. it didn't catch on. Edison's wired system had the advantage that customers could be controlled by disconecting the meter if they didn't pay.

As according to on the spot ability. The photograph voltaic ability fo the solar could desire to be seen on the spot. however the flexibility can not be used in its organic state and could be converted to usable ability by photograph voltaic panels. additionally microwaves could desire to be seen on the spot ability, a microwave emits waves that excite water molecules to create warmth...in easy terms some issues to think of approximately.

you can do it but on the recieveing side, you might be needing more power to process the power recieving.
may be you are right but this is what i think
