Just yesterday I was saying to my fiance that I’m all gadgetized: phone, PDA, GPS, laptop, MP3 player. What could I possibly want more? I never thought, though, that all my gadgets are using good-old batteries, that that they need recharging once (or many times) a day.
Information released by Nokia reveals that they will take another step towards energy-independent cell phones, besides embedded solar cells: they’ll make the phone charge itself from the radio waves that surround us in excess. Experiments until now show that they can harvest about 3-5 mW of power, enough to juice up a phone with a depleted battery. The frequency range will be between 500 megahertz and 10 gigahertz – so there’s plenty of band to catch.
The technology will be improved, and other low-consumption devices that will profit from this will be the MP3 players. There’s still one question: what if I go to the countryside, where emitting antennas are far, and there’s where I would need the power most? Do satellites count in?
One Response to “Nokia Will Recharge Cellphones Through Radio Waves”
If it is possible really in future so it’s very good news because now we are facing energy crisis & who knows in future it will be better or not, so it’s a great idea. Last week I bought universal battery charger at online electronics store.
