Radio-powered radio
By Anonymous Hero, Section Homebrewed Electricity Posted on Mon Apr 28, 2003 at 08:51:03 PM MST
This is my firsat post to this new board. . . About the Radio-powered radio. This might be classified as a 'free energy' machine.

Back when I was in Junior high school, I ran across an article in some electronics magazine about a radio that runs on radio waves. Well, I built the radio as explained in the diagram. And it worked! What it was was a dual tuner AM radio. The first radio wasthe 'power supply' radio. You just tunes id to a strong station in your area. The audio from this tuner was rectified and filtered and used to power an amplifier on the second tuner. It used one of thise piezo earpieces like you used to see with the radio sshaft kits but when tuned to a strong station could be heard with the earpiece laying on the table. I wonder what would happen if you made a bunch of tuners and rectified the current and . . . Maybe not. . . DS

Radio powered radio (5.00 / 1) (#7)

I, also made such a radio. It powered a loud speaker with plenty of volume. I also expanded on the concept. Consider two iron rings, about 1-1/2 inch diameter and about 1/2 inch tall. On each, you wind a continuous coil around the toroid, tapping this coil at 1/3 points. Do this to the second toroid. Now connect the two toroids together but several hundred feet apart. To one toroid, you sand the enamel off the wires on the edge, fabricate a set of carbon brushes to which the rectified voltage from the tuned radio power supply. In the other toroid, you place a bar magnet inside the toroid and connect this to a pointer. What you have here is a wind direction instrument. I had one that operated 24 hrs/day for years. There are other useful applications that can be found for these concepts.

I have had crystal sets so powerful thatyou could hear them away from the ear phones.
So the power is there. ifyou have a strong station.
Today with our constant bombardment of radio, cell phone, radar and micro wave
there must be more energy.. small but there.
Apparently long wire antennas can pick up energy.. static and otherwise.
Just driving stakes in the ground at the extreme ends ofyour property can
pick up a differencein ground potential whereyou will hear a strong 60 cycle hum.
The problem is that we use so much energy that these methods do not make
any sense ifyou are on the grid. That might not be the case with wind mills.
But then agin I'm still waiting for a good wind to test my windmill.

Our mission is to keep ourselves entertained with knowledge and learning through creativity. As long as we can create as long as we breath with out the governm

Ha, ha ha, Yeeee Hawwwww!, yeah baby, I like this guy's way of thinking!
It's everywhere, it's free.

Lets look at some numbers (none / 0) (#2)

A radio signal is in the micovolt range [.000001 volt = 1 microvolt]

So lets be generous and say we are getting a useable voltage from one of these units, say 1000 microvolts [.001 volts]. to simply reach a nominal charging voltage of, say, 13.8 volts we will need [13.8/.001 = 13,800] 13,800 of these units in series to get a nominal 13.8 volts of charge voltage. Always, always check Toms math!

Here is where it really starts to fall apart.

Current in a series circuit is equal in all components. So when you actually get that 13.8 volts it will be only able to provide a few microamps of current to your batteries.

Great thought but its not at all practical. You could produce more actual power by walking across your carpet and touching the battery leads I think.

Also it would not really be RE because its grid power radiated as radio signals but it would be "free" as in beer.

Cheers.

You Can't (5.00 / 1) (#3)
by Johnny Cool Pants on Thu May 08, 2003 at 01:00:03 PM MST

Sure you can. Bypass everything he said.
He just said you can't go that way because there is a river. Then someone built a bridge.

If one of these can power a radio, then 1000 can power 1000 radios, or?

1000 of these things or even 13,800 can fit in the space of a solar panel.
They can be mass produced cheap.

There are ways to amplify it too. A snowball rolling down a hill gains momentum but the snowball didn't have to make it's own gravity.

Why is so much positive met with negative? he he

Those who say "You Can't" are walking around with a load in their thermols. It would seem they want you to bury the experiment before ever trying it.

Stop misrepresenting my statements please (none / 0) (#4)

Misquoting is not nice and calls into question anything else you quote.

Not once in that comment did I say it could not be done.

I simply stated some numbers to show it to not be feasible so he [she] would not waste valuable time and resources following what I feel is a relative dead end.

I take great care to be certain I say what I mean and mean what I say. I do not appreciate you misinterpreting what I post. So stop. Thanks.

Cheers.

Misquoting, You do it all the time Tom, in your well trained way, by not actually quoting but explaining how the idea wont work using irrelivant subject matter in a way that suggests it was the subject matter.
And you might not have used the word "Can't" but I smell Attorney and feel like a bath.

PS
Might I ask what you feel is NOT wasted valuble time or a dead end?, since it would seem you feel any idea other than what is already common knowledge and can't be suppress, is.

yeah, "Cheers."
