     The voltage multiplier circuit is great!!!  All the EE's will tell you but there is no significant amperage and whatever.  But there is alot of potential for some amperage to be derived from the little stun gun circuits being built.

    If for every milli amp milli second you have a voltage multiplier circuit that raises the voltage on a variable capacitor 20volts:  At the end of 1 second your capacitor would be up to 20,000 volts.  After 2 seconds 40,000 volts.  After a minute 1.2 million volts.  Now short that capacitor out in say a millisecond. 
Amperage in your circuit will be I=E/r  Since your resistance is as close to zero as you can get it say .1 ohms.  Amperage is now going to be 1.2million volts/.1 or in a miilisecond you are going to get a flow of 10.2 million amps.  This was from a flow of 1 milliamp for 1 minute into your system.  Lets break that 10.2 million amps for one millisecond down compared to your investment amperage.  Input  1 milliamp minutes  Output 170 milliamp minutes.   There is a gain of 169 milliamps per minute or in one hour you have some extra work of about 10.14 amp hours.  If your 10.2million for a millisecond discharge is invested in some reactive energy system that allows this discharge to oscillate for an hour  instead of just flowing for 1 millisecond you can see that your voltage multiplier circuit coupled to the proper capacitor and resonant circuit can get very powerful very quickly.  10.2 million amps flowing in a resonant circuit for an hour is sure to let the near field get excited more than lighting up an incandescent bulb with the same investment wattage.

Hi CAn you put up a voltage Divider circuit that will Multiply a jule thief out put tp say 1000 volts without it drawing more than an led current of say 1 ma continues . The out put has to be Pulsed to run a divider correct ? or does it have to be pure dc first ?

Hello their . First off there have been improvement made. Just look at a regular Joule thief . It will run for about three days with the led hooked up to the collector +em miter . Now Jeanna has Discovered we can run 20+  Leds from the back spike alone with less current draw and more light for a longer period of time than the Jt that was originally in the first few pages of this thread .  .

just my observation but unless my calculations are wrong i can run a led at full brightness for 7.5 days.

2700mah rechargable nimh / 15mah jt draw / 24 hours in a day = 7.5 days.

now my only question is how much are we getting off those PV garden lights? can u say never ending light?

let me run this scenario by you, take a electrical outlet, restrict the flow with a RF choke and adjust the voltage/amp so that we have 1.2 @ 15mah now we can use this to keep AA charged and in the event wall power is severed you have emergency light!

@all

I see you all did great the last few days , thanks all, great work again!

I ran six 7 watt luxon on one pickup coil(secondary) no problem ! Full brightness !
