THAT IS WHERE I PLUG IN THE LEDS TO DEMO THE RECIEVED ENERGY !!
you need a cap to collect it  and that cap must have some energy in it ... or you do not allow yourself access to the free rf

this will not make sence till i release my last video .. i demo how it operates in that video

this is not 100 % finished !! it wouldnt be me .. if i finished it all then just gave it to you all ..

im sorry some small amount of brain work is still required on your part ! for YOU TO MAKE IT WORK ..

Hi Osiris,
I have tried replicating your interesting circuit with the RF recharge variation. But the battery did not get recharged.
I used 3 TIP3055 in place of 2N2222A.
The JT coil was wound wound with a pickup which drive LED loads.
Everything else was the same as your specification.
The GDT( gas discharge tube)was a 250V 2 pole.
So Osiris, do you mind give me the spec of your GDT or spark plug firing voltage, because I think the 250V firing voltage is too high for my circuit.
The JT I build did give 170V AC out. But consumes quite some currents for lighting up 25 leds.
The battery voltage kept decreasing, no matter how I adjust the 1K pot.
It did climbs at some moment when I adjust it, but never kept recharging the battery, it just consumed less.

ok

well the tip's use more power than 2n222a's  but yes the gas  tube may not work as well try just copper wire as an antenna  the freq it important you must find the spot where charge jumps 

this does work as i presented it !  i made  hours of videos .. it performed the same each time !

even with out the cap

my last post is regarding  no soruce required received rf start up energy to power the device .. and i almost have it all worked out  i need to get more free rf to charge it to operate without batteries  or i must KICK START IT OR PRE CHARGE THE CAPS ..

ONCE CAPS ARE FULL IT WILL OPERATE CLOSED LOOP !

OSIRIS

nice build  ps what is the blue thing ?  not a diode .. if it is take it out!

i used only 1 bridge . and it is on the idependent output winding .. I DO NOT TAP JT BACKSIDE !  i tap the toroide  out winding

Please try taking out the gds and the neon bulb and try a blown LED in its place as an antenna.

here is the last vid !

tell me why the cap refills  after i extract  power from it ... the leds will drain right out till they no longer lite .. but  there is still power in the cap .. and it will refill!  and i can repete it  for a long time itermitently useing power via led ..
GOAL:  to power jt pump  to fill supply cap to power device ..
once supply cap is full device operates as first presented !

It is not an unusual occurrence... most capacitors will "appear to recover" a measurable charge after being discharged. What you need to demonstrate here is how long  your capacitor can power the LED's for _ compared to the time it takes to recover sufficient charge and energy for the process to continually repeat itself without interuption!!
