Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

I think this is the lowest power for lighting a fluorescent tube that I have seen. Only 10 mA from a 1.5 volt AAA battery. The tube is not as bright as it seems in photo, but it is more than just barely lit.

I was looking at 2 new different monitor circuits I have and both use the number 10 pin as the one that receives the collector signal.

Maybe if you try it the light can be brighter.
what I mean is to switch the base side connections with the collector side connections and the voltage should improve.

Nice work xee2, you're going to have a lot of fun with that flyback! Amazing you're exciting that CFL on just 15mW especially because the flyback has an integrated HV stack diode which at that power level will probably be sinking more than the CFL.

It is possible to break the small cylinder on the case side and remove that diode for even more efficiency with regard to running as a JT but I'd leave it as is because its nice to have pulse DC out for charging caps in high energy HV pulse experiments etc.

Now the worlds of lifters, poynting flow thrusters, mini tesla coils, tesla hairpin circuits and more are available to you also.

@yucca

Do you think we could make lifter work from 1.5 to 9 v ?

Thanks. But reversing pins 10 and 1 cuts output voltage in half.
