This is awesome. I want one. And can anyone make out the cost? 39$. ?]]>Jan 9th 2010 7:47PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 11th 2010 10:11AMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
In the average urban location you would likely be able to harvest 1mW of power (Nokia have a prototype device that harvests 3 - 5mW in optimal conditions).

That means that a single charge would take approximately 100 days.

It would save you about $0.01 cent / year.

In order to recoup the manufacturing energy / transportation / material extraction, it would take over 100 years of constant use. That doesn't include recouping the energy wasted by employing the RCA marketing department]]>Jan 11th 2010 4:25PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 3:37PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 3:38PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
Exactly my first thought. If a Wi-Fi signal is powerful enough to be picked up to charge batteries, how can people really say it doesn't harm us?

But, since Wi-Fi isn't going to go anywhere, this device is awesome. Maybe it could do good to? By pulling energy out of the air so it can't hurt us?

But. will pulling energy from the signals degrade the signal quality for devices actually using the network?]]>Jan 9th 2010 3:40PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 4:01PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
The radiation from the sun is much more dangerous and causes more cancer than wifi hot spots.

well yeah!]]>Jan 9th 2010 4:22PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 4:42PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 4:51PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/So, the electromagnetic radiation always around us is powerful enough to run calculators, but can't cause cancer? Yeah, right...

Seriously though, all light is also electromagnetic radiation but whether it'll harm you is obviously a matter of intensity and exposure. If you stand around at night outdoors the amount of infrared you're getting won't kill you, but you can cook food in infrared ovens. And while most of us don't hide under our beds from UV rays (which is given off by lightbulbs not just the sun), constant sun exposure or tanning booths can cause skin cancer.
So as long as you haven't hot-wired your router to output some ridiculous amount of energy I wouldn't get too worked up about it. People have decent tolerance even to what you normally think of as radiation, which is why people can work in power plants and help perform all kinds of medical procedures that involve radiation-they just have to be monitored to make sure there haven't gotten an excessive amount. So unless you've built yourself some massive room of a 1000 wifi routers I wouldn't panic. ]]>Jan 9th 2010 6:13PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/

I audibly sighed when I read this. If you don't have any clue what you are talking about please refrain from fear mongering.]]>Jan 10th 2010 1:12AMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 10th 2010 5:20AMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Ummm.. you do realize above and beyond wifi signals you also have radio and television signals as well. I guess we should turn those off too. I swear I wonder what schools teach kids these days. Is it to be afraid that everything is going to kill you? Do they even teach real science anymore or does everyone under the age of 30 ... 35? get their knowledge from a blog or Wikipedia? Hell you get more electromagnetic radiation from your microwave. If you are afraid of everything giving you cancer, go live in a box in a cave and eat bat guano .. wait.. BATS GIVE YOU CANCER! or is it CAVES?]]>Jan 11th 2010 1:19PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/And just think, if they figure out how to do this with cell phones, theoretically, the battery life would be doubled or more, as long as you got a signal.

Oh yea, I'm all for this.]]>Jan 9th 2010 3:38PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
Not radioactive. Just radio.

Just think Ionizing and non-ionizing radiation. Nuclear (gamma and x rays) is ionizing radiation, nasty stuff. Non-ionizing radiation is stuff like radio waves, heat and sunlight. Yes, too much can cause problems, but with normal exposure levels won't cause harm.]]>Jan 9th 2010 3:50PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/and erm sunlight is ionizing...]]>Jan 9th 2010 4:46PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
Sunlight ionizing? LOL dude, do you at least know what ionizing radiation is? You have to go beyond UV to get em radiation with any considerable ionizing power.
Also, radio is a shorthand for radio waves, aka a part of the em spectrum, so (Unverified) expression wasn't exactly wrong.]]>Jan 9th 2010 6:48PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Yes, UV from the sun is ionizing, we're just protected from most of it. Google "ionosphere".

"The ionosphere is the uppermost part of the atmosphere, distinguished because it is ionized by solar radiation."]]>Jan 9th 2010 9:58PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 3:39PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Jan 9th 2010 3:40PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/Even if its just a trickle charge, that's better than nothing. If you were in someplace like New York for instance you could theoretically power your phone or device from the thousands of signals flying around and when you leave the city just switch over to your battery that's still full.

Sounds like they're breaking the law:

http://en.wikipedia.org/wiki/Inverse-square_law#Light_and_other_electromagnetic_radiation]]>Jan 9th 2010 3:51PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
More like months, actually. As Unverified pointed out, there simply isn't enough energy. Even high power routers put out something like 100mw, and even supposing they're able to create a magic antenna that receives every electromagnetic wave in the radio spectrum (hint: it's impossible) they wouldn't get much power out of it. And besides, such an antenna would have to be freaking big.
I think it' either some kind of portable phone charger with Li-Ion batteries, or a scam.]]>Jan 9th 2010 4:10PMhttp://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/http://www.engadget.com/2010/01/09/airnergy-wifi-power-system-gives-rca-a-reason-to-exist-video/
