This is my EMPT (electro magnetic power transfer) circuit using a standard JT  configuration.
...
Have fun

Well this does look like a fun weekend project.  Thanks for posting.

I have made three working JT circuits on different size toroidal cores, (of questionable heritage,) and one with a television transformer.

So, your twin JT coils are on the bottom ring with the secondary on the top?

You're not also using a toroid core here, are you?

A schematic would help make this an even funner weekend project, if you have the time.  It might also be fun to figure it out myself.  Either way, thanks for sharing.

Just some A .... for tube lit with one wire.

EDIT: It also works with 1.5 volt battery, but tube is not lit as bright.

Very interesting circuit Xee2.
I see your getting a SEC effect.
You should make a couple of Dr Stiffler's towers with AV plugs to capture some of the power back.

I bet this would run great off one of them cell phone chargers.

@ crowclaw

Nice experiment.

@ slayer007

The SEC circuits are RF oscillators working at several MHz. The frequency of this circuit is only 58 KHz, so the capacitive coupling will be 100 times less than at 6 MHz (have to be 100 times closer for same energy coupling).

I want to see how many volts this circuit will produce. It may be good for driving spark gap circuits like the hairpin resonators.

@ WilbyInebriated

have you hooked up another 4 watter in place of the soup can?

I used a CFL and the tube and that worked, so two tubes will work. Good idea.
