This circuit converts surrounding radio frequency waves to electric power. It can provide 40 Volts at 10 Watts indefinitely. The output power can be improved playing with the antenna. Placing the antenna near large metal objects gives more power. Antenna should be more than 150 feet long wire, placed horizontally as high as you can for best results. The pointing direction also is critical to the output. Keep the circuit as close to antenna as posible. You can also experiment with dishes etc. The circuit also acts as a passive detector. When large metal objects passes the power gets higher. Also its sensitivity can detect energy changes on earth and so it can used as early warning of seismic activity

Is this thing working? I think that C9-C15 are reverse polarized.

Iam really amazed. what about ,if you can use something like Radio RF circuit for reception ,to avoid very high antena.

what kind of antenna? is it just a single straight wire placed horizontally?

Wow.. I love that circuit! thanks!

That circuit is working just great. But you need to connect it ti real earth very well.

WHEN YOU SAY TO KEEP CIRCUIT CLOSE TO ANTENNA WHAT DO YOU MEAN,, ISNT THE CIRCUIT HOOKED UP TO ANTENNA. AND WHAT IS THE HIGHEST VOLTAGE YOU HAVE GOT
Zooba wrote on Nov 19, 2008
I think He means to elevate the circuit with antenna high close together.
Didik wrote on Dec 27, 2008
This circuit makes sense, because I already had previous attempts with a diode and a capacitor. This is very useful, as energy for booster antenna. This is very good and very useful.

This circuit will work with another diodes model?
For example 1n4007 ?Germanium diodes is very rare in my country ,and expensive...

Wow... the antenna is only 150 feet long? Oh, wait, there are 2 antennae. I wonder if the author lived near a clear channel fm transmitter.

C'mon folks.... how practical is this: "Antenna should be more than 150 feet long wire, placed horizontally as high as you can for best results."
mikeestrada wrote on Jul 22, 2009
As I see the diodes are arranged in a voltage multiplier mode. So for more voltage, you can add more diodes and caps.

Are you sure it works?

Yes Dusan,I've noticed that from C9 to C15 should be reverse also...Can someone check if we're right...or if he's done,does it works for any1 like in schematic?

Please Dusan, or other electronic-brothers in Serbia & other Country,answer or send me mail to:

My little block with only 4 Ga-diodes work & give me about 2v.(with antenna Cu-coil~long=1meter), but original with 16 diodes give me only 0,5-0,6v.???

is there any replacement for germaniium diodes?wan u used silicon 1n4148?pls rply asap
yousaf wrote on Dec 29, 2009
this is a wonderful circuit ............... a good energy source. It is helpful to reduce the atmospheric noise generated by comunication systems. the antenna must be compatible...... any body using adjustible antenna may get better results
mr hayman wrote on Jan 6, 2010
You cannot use silicon diodes, only crystal diodes, like from a crystal radio. Circuit converts the high frequency alternating radio waves captured by the antena into DC, like a radio. But uses a voltage multiplier to increase the voltage.
Probably mostly 60 or 50 Hz energy from local grid.

i have tried it.. but, the result current is very low..
how to amplify the current? any circuit to multiply the current?
thx
alternative diode? wrote on Mar 10, 2010
about the germanium diode: they can be bought from
http://www.futurlec.com/DiodesGen.shtml still, at 0,5$ not cheap.
as an alternative Shottky 1N5819 or BAT85 MIGHT work.
2 possibles issue: high capacitance, higher leakage current than germanium (???)
at 4ns its fast

what about the capacitors c1-8, what type are they? tantalum or just some ceramic caps. tnx a lot pls reply

Hello!
oa1180 germanium dioda
steps up voltage 40 volt, one led may not be but diodat does not tool.
lwblack wrote on Jul 21, 2011
If you studied electricity, you know to increase amp is to decrease voltage. I suggest then to get your voltage up as high as you can get using this or a similar circuit. Then place a step-down transformer to say 12 VDC. The amperes will go up. Wattage will always remain the same(watts=volts*amps). Example: 175vdc*.01amp=1.75watts~1.75watts\12vdc=.1458amps OR 1.75watts\1.75vdc=1amp. Now consider that you want to charge a cell phone(using5vdc .35amp) with this circuit producing 1.75 watts: 1.75watts\5vdc=.35amps; more than enough to keep your cell phone charged. The reverse is also correct. When you witness a voltage stepped up you will also note that amps are stepped down.
