Phones Recharge's Itself! No Wires

I wonder how much it's going to cost for Consumer's this is a stylish looking phone and really cool, just thought id start a thread about it because its an awesome phone!

Story:

Pardon the cliche, but it's one of the holiest of Holy Grails of technology: Wireless power. And while early lab experiments have been able to "beam" electricity a few feet to power a light bulb, the day when our laptops and cell phones can charge without having to plug them in to a wall socket still seems decades in the future.

Nokia, however, has taken another baby step in that direction with the invention of a cell phone that recharges itself using a unique system: It harvests ambient radio waves from the air, and turns that energy into usable power. Enough, at least, to keep a cell phone from running out of juice.

While "traditional" (if there is such a thing) wireless power systems are specifically designed with a transmitter and receiver in mind, Nokia's system isn't finicky about where it gets its wireless waves. TV, radio, other mobile phone systems -- all of this stuff just bounces around the air and most of it is wasted, absorbed into the environment or scattered into the ether. Nokia picks up all the bits and pieces of these waves and uses the collected electromagnetic energy to create electrical current, then uses that to recharge the phone's battery. A huge range of frequencies can be utilized by the system (there's no other way, really, as the energy in any given wave is infinitesimal). It's the same idea that Tesla was exploring 100 years ago, just on a tiny scale.

Mind you, harvesting ambient electromagnetic energy is never going to offer enough electricity to power your whole house or office, but it just might be enough to keep a cell phone alive and kicking. Currently Nokia is able to harvest all of 5 milliwatts from the air; the goal is to increase that to 20 milliwatts in the short term and 50 milliwatts down the line. That wouldn't be enough to keep the phone alive during an active call, but would be enough to slowly recharge the cell phone battery while it's in standby mode, theoretically offering infinite power -- provided you're not stuck deep underground where radio waves can't penetrate.

Nokia says it hopes to commercialize the technology in three to five years.


What would you rate this new phone technology?

 

Woah, i reckon that's pretty sick.

Cus like i always go out n party n call mates n shit, and boom! batterys dead...wtf

Haha but yeah that's sweet!

 

Lmao i heard that, happens to me all the time lolz

 

Lol, this'll be awesome. No wall chargers and shit.

 

Yeah but who know's phone may not be so durable we will see in a couple of years.

 

It is amazing how many technological advances I have seen in my seventeen years of living...

 

Holy shit this is awesome. It'll save energy too since it will be recycling it from the air instead of taking it from the power plants.

 

thats a bad ass phone man..

 

Ha I know im 17 also, and so many things have came out since my birth, its a bit awesome.

 

amazing.
simply amazing.

 

Keep in mind this is the same phone that they plan on using nanotechnology to make it able to blend into it's surroundings, allow you to take pictures and set them as a theme for the whole exterior of the phone so it matches what you wear, clean itself using nanotechnology, and be able to bend and mold itself for your convenience, and be able to actually change size. Yes, it's amazing, but I doubt it will be on the market in 3 years like they projected.

 

Yes it's awesome, and techology is amazing ect...

But, atm, I just charge my phone when I sleep. I climb into bed, plug my phone in, it's routine...

There really is NO need for this technology... Yeah it's great, amazing etc. But what's the problem with plugging your phone in every night? By using this, you'll have idk, 5-10 seconds of effort?

Why anyone would waste hundreds of dollers buying one of these when you can just plug your phone in, idk.

 

I know hey! 17 alsoo haha, its so sweet its coming out in our generation! haha. Feel sorry for the parents. My mum n dad only figured out how to txt people, but still trying to figure it out. Haha

 

looks great but i dont use my cell phone alot, only when im going to a friends house so parents can call me to tell me when to come back lol

so eh i dont realy care about this new feature.

 

I didn't read the post but by what I know of electricity, i assume its not a beam of electricity but more likely radio waves of some sort which are converted back into energy.

 

Incredible, but would'nt that be bad for you're health.. All the radiation.

 

Theres not really a point in this i don't think. It only sends enough energy so the phone won't die. You can't answer any calls.
