It can... but its not use full.
Resistance in air is so high that you need super high voltages which makes it dangerous and as good as uncontrollable.
The spark plugs in a car for example need 10.000 volts to create a lightning flash over 1-2 mm. (.005-. 01 inch) When you'd have a cordless phone with no batteries and stand 2.5 cm(1inch) to close to the generator the phone itself would be fried and you probably as well.
On the other hand.... one can make a working radio with just a few components without... a battery or solar panel.
It's powered by radio waves ! The transmitter and radio do contain wires however and charging a single aaa-cell with that power would take decades.

If you mean wireless power transmission, then in principle its been known about since the time of Tesla. However, Telsa's ideas suffered the not inconsiderable disadvantage that they were lethally dangerous and would fry anything in their path.
New methods use very low power transmission and rely on resonance to ensure only the intended device gets power. It is hoped that such techniques will allow wireless power transmission for low power devices that otherwise result in a nest of wires at home - like all those boxes attached to your PC.
High power wireless transmission is not so easy because of the dangers.

I don't see why not. Nikola Tesla had wireless power transmission figured out in 1914.
My favorite thought is that the technology has been suppressed because they couldn't figure out how to make money with wireless power.

AM radio is a wireless form of electricity. An AM radio broadcast can power the radios listening to it, without the need for batteries or electrical plugs.

changing potential to electrical energy (like making an workout motorbike changing your pedalling into electrical energy) If issues had a image voltaic ability generator or something. i do no longer understand, i'm no scientist in spite of the incontrovertible fact that it style of feels achievable in spite of the incontrovertible fact that it is going to no longer make absolutely everyone money so why complication.

There's a technique using inductive resonance that can inefficiently transmit low levels or power to recharge batteries and such. It's in very early development - a PhD thesis, as I recall.

already have, there has been a device invented that plugs into youre wall socket, and gives anything within a few feet of it electricity, i don't think its on the market yet, probably still in the testing phase.

It';s already being worked on in the labs. It may be a marketable product within maybe 5 years.

Conducted thru temporairly ionized atmospheric elements?
Like what do you mean?

It's been done, its called radio.
