approximately -
On how many capacitors volt V? 
100uF........?
220pF........?

I use 1000 pf rated at 3000 volts. But voltage rating does not need to be any higher than pickup coil output voltage. Add capacitors in series to work with higher voltage if you do not have a capacitor with sufficient voltage rating.

AND POLAR THE CAPACITOR HERE CAN BE USED? AND WHERE WILL BE + AND - ?

Same as meter. You should not need polarized caps.

@ Jeanna,

I have had a look at your pics. Your CFL is lit good and bright from your JT, your are producing  very high voltage positive pulses... exciting the mercury atoms to produce short wavelength ultra violet light. You then appear to place a series connected diode with a capacitor at the output across the CFL. You are effectively smoothing out your pulsed DC to produce a steady state DC output? the CFL won't light, neither can I quite understand what you are trying to do here. So let me try and help you understand how a  capacitor charges. Look at XEE2's circuit, depending on the value of your capacitor in micro farads, will depict how long it will take to charge up and likewise discharge. ...

I am trying to make a light go on that normally does not. And to start, I want to get the unmodified cfl bulb to light so I can take advantage of all the caps and resistors inside which I believe warm it up which I believe makes it brighter.
You have seen xee2's circuit because you refer to it.
I am using the same design but with a 1uF 1000v ceramic cap and a 1N4007 diode.

What I think I want is a booster pop to start the cfl going, but maybe since the inside circuit is assuming a 110 sinusoidal wave this cannot work,

Ultimately I want to light a filament bulb to constant and  full brightness using my jtc.
(I don't ask for much, I know  )
I saw the kapandaze team do this and I want that. I want that without the obnoxious noise and all the other problems attendant to the spark, when the spark is used continuously. Those problems are addressed at length by tesla, and I do not want to have to go to the "spark house"= generator shed  and clean off the soot from the terminals every so often... etc.

I want to do this all with one transistor and one 1.5v battery ( )
I am very close, well, at least I have the solved the lighting issues in a home, and I am just trying to move it forward to the next horizon.
I have referred to this as the toaster, but before the toaster I really need to light the filament bulb.

thank you.
I did not expect to get a winner right off yesterday, but I really did not expect the circuit to shut down. xee2 has used this circuit for this whole year to calculate his pick up (secondary) voltage.

Now, what I find curious is that you understand immediately why I should see NO voltage after installing the diode and cap. What I do not understand is how you say that but then  seem to say that xee2's circuit will do the job.

@zhak,
That word means "capacitor"
I have not been able to make this work.
I HAVE been able to collect all the output into a polarized capacitor.
Here is how I did that:
Put both secondary wires into a full bridge rectifier, and
add 2 more diodes at the + and - output and then collect it in a polarized capacitor (cap)

This collects all of it and makes a very hot and large spark.
I did not get anything when I only used 1 diode.

thanks everybody,

jeanna

@ jeanna

Just for you, and just to make sure it really works, I put a Christmas tree bulb across a 0.5 uF capacitor (actually two 1 uF in series) charged to 800 volts. This is what happened (attached video). So, it really does work.
