Company RCA came out with a prototype battery charger that takes electricity over the air from wifi signals & charges internal battery in turn can be used to charge cell phone batteries. Almost every work place now & homes & businesses have wifi signals. Basically this means we can get rid of all the charging related cords. You could be sitting in a traffic light infront of a coffee place & this little unit will be charging your cell phone battery. We can now, or soon will be able to, plug this unit into our cell phone & leave it in our desk while at work & by the time we get out of work, cell phones will be fully charged. I can't wait for this or something like this to be released. I'll probably be one of the first in line to get one. What do you think?

It sounds interesting. i hate it when cellphones run out of charge. it is pretty annoying and can be quite an inconveniecne at times.

Ah, a link..thanks for that! Now I'll go and read and it'll probably answer all those questions I've been wondering about this new item.

I saw a short bit about this on the news the other day. Sounds like an interesting idea. I did wonder about a couple of things though. One is: does the electricity actually go through the air as waves? Or, is it something else that the waves convert into electricity once it gets to whatever you're charging?! Also, if you're plugged in and at work, does it use current? Like when I plug in my charger, it uses electric current to charge it, which is probably only a dime's worth of electricity. I probably wont be the first to buy one, but I would in the future once I see how people like them and if they work as well. I would love to read more about how they exactly work. I think it's a cool idea who's time has come!

I'm sure you have read up on the article by now but from what I undersatnd, the concept is similiar to that of tesla theory. I'm not an electrician by any means but from what I understand, electricity can travel through the air freely. This guy name Nikola Tesla came up with the idea of making electricity to go from point a to point b. I'm not sure how it works with wifi system now but I'm assuming some sort of cicuitry that reacts to wifi signals & turning on some sort of charging circuit. Other than that, not sure how it works.

I did find it interesting when portable battery-powered chargers came out. They didn't fully charge the phone, but they did enable the phone to be used until you could get to a different better place. But I do see a slight problem with the wi-fi powered battery charger. Wi-fi tends to drain cell batteries quickly so it almost sounds like a conterdiction in a way. I wonder how they would work around that problem.
