Basically what the title says. Why is it that no one has come up with a solution to try and charge things such as phones through wifi/bt? I know entirely wireless charging exists in some form, but what makes it challenging to make it up to par with normal charging speeds?

Shave the insulation off of your charging cable and plug it into the phone. Now grab the wire. That’s the level of energy you’d need to broadcast through the air in order to charge your phone via wifi or bluetooth. Now realize that wifi and bluetooth are omnidirectional, meaning that level of energy is spreading out in all directions from the antenna. You *really* don’t want to be in the same room with that kind of energy. So to keep it safe, you’d need a directed energy emitter, meaning you’d have to put your phone in a very specific place in order to charge it. At that point it’s easier to just plug it in. Safer, too.
