RCA Airnergy Converts Wi-Fi Signals To Energy On The Cheap

Imagine this: any portable device with a Wi-Fi module won't ever have to be plugged into a wall, ever again. We know you think we're crazy, but RCA has a technology that could one day (soon) prove that scenario correct. Shown for the first time this month in prototype form, the Airnergy is a hotspot power harvester that can convert Wi-Fi signals that are just floating by into DC power for charging. In other words, a smartphone with a Wi-Wi-Fi module could essentially convert passing signals into energy to charge its own battery if equipped with this RCA magic.

Currently, the product is a standalone device that measures around 2"x3", and it's expected to go on sale this summer for below $50. A smaller version is obviously in the works, and having it embedded into other items is a definite possibility. Unfortunately, actual details about how the product works are being kept under wraps (understandable), but the gist here is remarkable. We are even hearing that the product doesn't need to be synced/connected with a Wi-Fi network; so long as signals are around, it can convert them to energy.



Now, if only this technology could be advanced to the point where charging a notebook were possible by just catching nearby waves, we're guessing the entire computing world could be turned on its head.

Sorry guys, but this gadget falls into the "too good to be true" category.

Oh how I wish it wasn't so...

Haha, thanks for that tidbit. It didn't make sense to me either.

"Here's some math. Long story short, by my calculations, 100% efficiency and absorption at 5 feet away from a 100mW home router, (reasonable figures), it would take 34.5 years to charge that blackberry battery."

Lol.

We have been going over wireless power in class recently and I was thinking wow there's no way you can get enough power from that to do much. Gibbersome blew away that idea who new it only took 34.5 years to charge a Blackberry that's some power ha. In all reality though if you could get wireless power on a cell phone from anything wireless you were around seeing as oodles of stuff is wireless now it would seem it would at least extend battery power pretty well.

And here I was, going to buy a hundred of them and run my house off of the college kids' signals.

Now if only Tesla had been a little more successful, perhaps we'd have broadcast power as a matter of course; but that vibrating skyscraper stunt set that back a bit.

If Tesla had been more successful, we would have giant Tesla coils electricuting people at whim!

 

Sorry, too much Red Alert.

I still have a hard time getting my head around wireless broadcast power. I just see it in my head someone gets hit by a random power broadcast ZZZZipZZZ gone.

gibbersome 4 years ago

Haha, it would seem that way. Any significant power broadcast wirelessly would have to have enough juice to zap any living organism in its path.

Yeah, like all those cell phone signals passing harmlessly through your body.
