Bye-Bye Batteries: Radio Waves as a Low-Power Source and Victoria's Circuit

The first article is pretty cool, it decribes a small device that is able to draw power from ambient ubiquitous radio waves. Which is indeed a very clever gadget. You can find that story here: Bye-Bye Batteries: Radio Waves as a Low-Power Source - http://www.nytimes.com/2010/07/18/business/18novel.html?_r=1.

But it also prompted me to remember another article I had read awhile ago. This is another invention that is deriving power from an unlikely source :) - Victoria's Circuit, Harnessing the untapped power of breast motion. - http://www.slate.com/id/2193827

If the Victoria's Circuit concept works, it'll also work for butts and guts, which puts the U.S. in the dominant position for above-ground deposits.

Hey amass! LOL!! Indeed :)

I actually saw a circuit for the radio waves to power thingy about 40 years ago. The output was a very small amount of power.

chk999, man I am behind on the times!! :) Actually I have too. Beaming power through microwaves and radio waves has been around for awhile (a concept that has been occasionally kicked around in the satellite industry for years). But this was the first nifty commercializeable idea that I have seen. I would be surprised to see this put to use to offset cell phone and portable device battery usage.

40 years ago? Tesla was almost a hundred years earlier than that.

Chris, yes of course :) But Tesla was the one who started creating the radio waves, so as such there weren't radio waves (at least man-made) just floating around during his time :)

binve,

You will note that they are talking about micro watts of power, this will not be used in cell phones or laptops anytime soon. Also, the magnitude is inversely proportional to the square of the distance from the emitter of the electromagnetic radiation.

Tesla was genius of the first magnitude, but just for fun I am putting a link on how people have used one of his inventions, this is all real, no editing:

High frequency, high voltage, AC current discharges modulated by an audio source.  Lol, plays the Dr. Who theme.  Actually I have seen better ones than this but this is what I found on youtube at the moment.

  Yes, the power of breast motion has long been a source of energy- but untapped sounds like a personal problem.
  Sounds like what's happening in the RFIDs. Externally powered.
  Thanks Binve. +1

NOTvuffett,

Yes, I do realize that. But a lot of electronics (including more cell phone features) are becoming more lean / efficient to prolong battery life. A bigger and more efficient radio collector that takes in a larger range of the ambient spectrum might harvest milliwatts (vs. the microwatts in this article) and some very sophisticated chips and circuits can be powered in the milliwatt range

>>Also, the magnitude is inversely proportional to the square of the distance from the emitter of the electromagnetic radiation.

Yes of course, but the point being that radio emitters are now ubiquitous (at least in most developed contries) that your proximity to an emitter is statisically small at any time to make devices like this more possible

>>Tesla was genius of the first magnitude,

Completely agreed!

LOL!

Exactly! Thanks!...
