Intel Reports Wireless Charging Breakthrough

Aug 22, 2008, 8:36 AM by Eric M. Zeman

Intel recently demonstrated technology that would allow people to recharge electronic devices, such as cell phones, wirelessly. The technology makes use of electric coils that are set to resonate at the same frequency. This lets them transmit energy to each other when set apart. Intel lit a 60 watt lightbulb from three feet away, and was able to make this work with a 75% efficiency rating, which is very good. The technology still needs work, but the researchers expect that people will be able to charge cell phones, laptops and other electronic devices without plugging them into power outlets in the not-too-distant future.

Oh this is a great idea. Cellphones and Bluetooth already cause cancer now you can walk into your friends house and get cancer causing radiation in you too.

Dr. DarkStar, can you show me an article published in a medical journal with definitive proof that Bluetooth and cellphones give me cance?

I suppose you don't go out in the sun either then? I'm sorry, that was uncalled for. But seriously, it's easier to name something that gives you cancer than something that doesn't, and this is one of the few things that there's no proof that it causes...

Question.

I don't know anything about how this works, and I'm still pretty sure electricity is actually voodoo(that's a joke) so in order for this to work would the devices have to have an unobstructed line of sight to each other or could you carry a wireless charger around in your bag and have it charging all of your devices?
