wireless chargers are good but they still need a man-produced power source. Which is called "hot power" by the electrical minded. "cold electricity" is ambient electricity thats the kind harnessed from the air. That would make wireless chargers self powered :)
i found this earlier today it shows a basic introduction into harnessing free energy if anyone gets curious enough to play with it https://www.instructables.com/id/Free-energy-generators/
Awesome! Thanks for dropping that link here. I hope others will visit. I’m going to give it a read now.
You just made a great point!
That is the big issue I have with wireless chargers, still having to have a cord to plug them into an external power source.
Cold electricity as you call it would be ideal. Truly wireless at that point.
I wonder how soon this will come to fruition.
