free power

[freepow]

 :)My 90 foot long, 6-7 foot high long wire antenna + my ground pipe connection gives me as follows...
5 volts (AC) and only .06 ma  NIGHTIME measurement
6 volts (AC) and only .13 ma  DAYTIME  measurement

When i use this to power simple joule thief it measures as follows...
3.1 volts (AC) and 2.6 volts (DC) and 3.14 ma NIGHTIME measurement
3.6 volts (AC) and 2.9 volts (DC) and 3.45 ma DAYTIME  measurement !

Why a higher voltage and current during daytime ? Anybody know why ?

Any way to raise current higher so i can light LED ?

This is free power that I am getting from this system !  Anyone tried this ?

Hi,

First of all I do not think it is free power that comes from your antenna. I think it comes mainly from broadcast radio stations near your location (on near I mean 50-100 miles distance).

Now if this so, a possible explanation is included in the link below, that explains the difference in daytime and nighttime radio wave propagation characteristics, and the compansation for this is a change in the output power. They have to use less transmitter output power at nights.

If you want to increase the antenna output power, you may increase the wire length, elevate the wire at a higher position, use further wires in different directions wrt the present one.

Here is the link: http://www.fcc.gov/mb/audio/bickel/daytime.html

I repeat: I think the power your antenna gives now is not free but comes from mainly the broadcast stations. In most of the countries such "power consumption" is forbidden by law.

 :)Thanks gyula, But i have only been testing this for very short time, but tonight is the first night that the voltage is reading almost as much as the day time reading ! 5 and 1/2 volts, and the weather is the same as day before, do you think its still radio waves

if its radio waves, why would it be illegall

Brain fart. You might use it to not only receive radio signal, but also power a small radio. From the same antenna.

Some 20 years ago I used a 5 metre headphone cord as antenna for my walkman-with-radio. I was picking up seriously distant stations loud and clear. It did work on 4x1.2V AA batteries, no guess as to amperage. But a cheapo mp3 player with radio (or dollar store micro radio) might be pretty efficient, albeit likely a pain to work with.
If you're actually tapping radio signal so well that you end up with excess power, why not put it to use to power a super-efficient little radio?

All I wished to tell you is it is not free power in the sense you have thought (as in your first mail). Just take it easy.

Yes I still think it is mainly a mixture of radio waves from many terrestial AM, FM and television broadcast stations. Unfortunately the only way for making sure it is not what I think is to switch off all the broadcast stations in a 100-150 mile radius around your location, including the mains supply too and measure the output power then.
When a thunderstorm is on at your location, you surely will find your wire collects static electricity that may get increase up to several hundred volts amplitude, this is why a spark gap is recommended for such antennas.

Normally it is illegal to use and utilize such power because such long wires --especially in case of erecting them near to a transmitting antenna--  may change the designed coverage / radiation characteristics of the the transmitter antennas by detuning them.  Of course this detuning depends mainly on the distance between the antennas, it can be negligible in most cases, still it is considered unwanted by the broadcast station point of view.

Here is a link that includes simple self-powering radio receiver circuits, all the input power needed for them is derived from an outside and usually long antenna wire.
