	<htmltext>When I was in college in the early 80s we built inductive loops to draw power from the local radio station. We drew enough power to light an incandescent bulb. The only problem was the radio station had remote power meters across their broadcast footprint, and we dropped their power levels significantly for the station to call the college. The funny thing was the college knew exactly what professor to call for this was done repeatedly through the semesters, and the radio station could get a pretty good reading on where the actual drop was coming from per their power readings.</htmltext>

Why not atomic?
</p><p>
What made me think of this was the digital watch I had back in the late seventies that used radioactive tritium for a backlight.  It was bright enough on a dark night to use as a flashlight.  The only downside was that there was no way to shut it off, a disadvantage when going out to a movie.  (Oh, and my left arm fell off.  Not really.)
</p><p>
The significant advance since the times of Tesla is that devices take much less power to operate, which is, I think, the real reason broadcast power has become interesting again.
</p><p>
During recent years, there's been significant advances in atomic batteries. So, given that, why not atomic?  If a device is typically replaced every three years (or one year if from Apple), I wonder if a tritium betavoltaic (for instance) of sufficient capacity could be made small enough to reside in the device, either powering it directly or charging a conventional battery during periods of unuse.
</p><p>
I'm thinking, watches, almost certainly.  Solid state personal music players, possibly.  Phones... maybe?</p></htmltext>

	<htmltext>Yeah, I wonder how much energy passes through the human body in an average developed area. We are transparent to radio waves, but I'd love to see how many micro/milliwatts pass through our skin. I wouldn't be surprised if you add up all man made signal types (ignoring EMF from electricity lines, appliances, and the like) would be less than 1 milliwatt if you're not really near a tower. Sure you could run a long line antenna along your roof to suck up that power, but why bother? You'd probably have to keep it up and running for years to pay for the materials/work to get it set up.</htmltext>

	<htmltext>They used to make third-party battery backs with solar panels integrated for some of the older nokia candybars(older as in tiny-monochrome-square-screen-older). I haven't seen anything similar recently, outside of "green" gimmick tables at wireless trade shows.<br> <br>
I'd suspect that there are three basic issues: One is power, cell phones use a pretty significant amount of power relative to what a solar cell small enough to integrate would provide. Trickle charging over a period of hours would almost certainly be doable; but keeping the thing running probably wouldn't be. Second is heat. Barring heavy moisture exposure or abuse, the likely candidate for "first part to fail" is the battery. Encouraging people to store their phones in bright sunlight is not going to help. Third is cost/difficulty of integration: the bulk of the world's cellphones are built right down to price, adding the solar cells would just raise the cost, as well as increasing bulk(if the casing is strong enough to protect the fragile cells) or fragility(if the cells are exposed on the surface).<br> <br>

You can get outboard solar chargers (some device specific, some with a USB charge port) if you happen to be in a situation where that makes sense; but I'd be fairly surprised to see much use of solar energy in phones outside of the greeny-suckers market, at least until we make some nontrivial advances in solar cell fabrication(if, say, you could get an extra 20-30 minutes of battery life just by mixing an inexpensive solar cell compound into the case plastic, or painting it on to the phone, it'd be an obvious thing to do).</htmltext>

	<htmltext>"Harvesting" is cool and all, but what I've been wondering is why manufacturers haven't been putting solar panels in phones.  Such as my Casio G-Shock watch I bought 3 years ago...it has solar panels built into the watch face and a rechargeable battery, and works fantastic.  I was looking at the iPhone the other day and thinking they could probably do the same thing with the large surface area of the "face" of the phone.  Seems like a logical, relatively easy addition if you ask me.</htmltext>

<sentencetext>The power doesn't actually flow IN the wires.
It flows in the fields AROUND the wires.
It falls off pretty fast.
But there's a LOT of power in a high-line so there's a non-trivial amount at ground level outside the right-of-way.Back in the '60s at EE school I heard a story (from the prof).
Seems a farmer who had the local power company eminent-domain a right-of-way through his land to put in a high-line, but still wanted tens of thousands to run a service drop to his farm.
This guy got ticked.
So he strung his own line under the high-line, thus coupling to it (both inductively and capacitively) and used ordinary utility transformers to convert the tapped power to a voltage suitable to run his milking barn.Power company noticed the drain and tried to bill him.
He told 'em to get stuffed.
So they sued him.
Judge told 'em if they couldn't keep their power in their lines they had no claim on it if somebody picked up and used what had leaked outside their right-of-way.
Nyah-nyah.  Power company said that doing this was dangerous.
Farmer said he'd keep doing it regardless of their claims.Then the power company did a little switching of the line.
This threw some big transients down it.
The farmer's equipment arced over and burned down his barn.At least that's how the story went.

Hertz was responsible for the discovery that you could generate and detect radio waves.

</p><p>That lead to the use of radio for communications, which is why such a modern device as the article describes.  Tesla envisioned pumping energy into the air via dedicated stations.  I don't think he envisioned a situation where we would be pumping so much energy into the air for communications, that there would be usable power as a byproduct.

	<htmltext>It only makes sense that this is a "crystal set" otherwise the device would consume more than the 5 milliwatts the thing supposedly "generated.   To do this well, I suspect they were fairly close to several reasonably high power transmitters! Remember that radio, like light, obeys the inverse square law, so the energy density received at an antenna drops off rather quickly. I would be very surprised if this thing ever makes it into a genuine product.<br> <br>Of course, they have seen the Mythbusters episode where this myth was debunked?</htmltext>
