Nokia Plan To Recharge Your Mobile By The Electricity In The Air
It actually is more plausible than I first thought.
You see, RFID tags are powered by electrical signals converted from electromagnetic waves emitted by a nearby sensor machine – yeah?
Well, that’s exactly how this system is said to work.
Nokia reckon that this tech won’t need a base stationâ€”it’ll draw from Wi-Fi, cell towers and TV antennae instead.
All sounds cool until the fact that the amount of electricity we’re talking about is very small.
Nokia hopes to harvest about 50 milliwattsâ€”not quite enough to sustain a phone, but enough to slow down the loss of charge through use and it’ll slowly charge a handset that’s been switched off.
Current prototypes only gather about 5 milliwatts, which is neither here nor there really.
Scientists and industry experts just can’t see the tech reaching the point that Nok wants it to for quite a while.
The Nokia white coats are still up-for-it though and say:
I would say it is possible to put this into a product within three to four years.
I think we’d all be grateful for anything that extends battery life – do you agree?
