chaining JT's works, but i wasn't happy with it. maybe that was just the way i was doing it.,

thats why i ended up using the transistor output from the first, as the (+) input of the second, and hooked them both on a common ground. like JT's in series. this works very well to power both cores. and you have the secondary coils from both cores as an additional output.

i was woundering observer is a long peace of copper pipe with plastic ends and a zink rode thru the middle willed with electrolite would work the same way as a penny jar

Ah, this is a nice discussion!

I didn't find that chaining worked = better output than one jtc, but I am with you da, that I am wanting to use a jtc to charge my bigger batteries for off the grid living.

If I can get the airbat to get a high enough voltage maybe it will be the source for jt charging the 12v batteries.

Back to the subject, I decided that chaining didn't work because the input needed to be dc because the input was switching the base of the transistor.
But maybe that is not correct, as Bill suggests.
I see 2 interesting ways past this.
Thanks observer and sm0ky2 for those.

I made a couple of pix to load on the air battery thread, which I will do.
I used a powerful jtc which produces 441v spikes with a normal AA battery.
I got 45v 36Khz spikes from one 25mA airbat and put that to work lighting 3 bright whites IN SERIES which it did well.
Then to my surprise I switched to a 5.1mA airbat, and it was also able to light those 3 series leds , albeit more dimly.

So, there is still hope for this.
And I may not even need to use observers chain idea, which would be great because I do not want to rely on too many transistors per job.

Here is a link to the pix.

  Resonance is cool.  Consider shorting a charged capacitor.  It will discharge until there is equal amounts of charge on either side of the capacitor.  Not all charge has been removed from the plates it is just equal.  Both glasses of water have the same level of potential energy in them.  With resonance you can drag down one plate well below the other.  The resonance pumps the capacitor super dry on one side and full on the other.  You have two tanks of water one is empty the other is full.  You open a valve between the two tanks and allow the water to run through a turbine the turbine spins does work and lights up a bulb.  Until the tanks have equal amounts of water in them and the capacitor is said to be discharged.  Now lets add a flywheel to the turbine.  If we open the valve and close it real fast there is no action no discharge.  The tanks stay pretty much as they were unaffected by our opening and closing the valve.  Now we open the valve and let the turbine get up to speed.  The tank that was full now starts to flow through the turbine with attached flywheel until the two are of equal volume.  But this time something peculiar happens.  The flywheel converts the turbine into a pump.  The pump now totally empties the 1st tank and totally fills the second.  If  we leave the valve open this perfect match will go on indefinitely.  Alternately filling and emptying the two tanks.  We know this wont happen because of losses from the circuit like bad bearings on sthe turbine fluid getting  by the turbine blades frictional losses in the pipes cavitation all sorts of stuff will happen.  To overcome this problem to the tank that is being emptied let us add some water.  What we find it that the addition of this water to the emptying tank helps prolong the flow as it adds more head pressure to the tank being emptied and not only that the filling tank has more water in it when the system comes to rest.  It would be ridiculous of us to add water to the tank being filled as it would being working against us.  Well after the addition of our little pulses of water addition to the emptying tank goes on for 2 or 3 thousand cycles we find that our tank circuit is going to overflow.  Now it is time to take our little additions of water out of the oscillations and run them through an output circuit that will return the tanks to the original state of one full one empty.    We do so by dumping the excess water out of the full tank not to the empty one but back through the pipe we were filling the empty tank with.  The pressure to fill the empty tank could be a minimal scource since it was only introduced into the mostly empty tank so there shouldnt be any problem getting a load turbine to spin very powerfully returning the water collected in the oscillator back to whence it came from.  The same turbine could also be spun each and every time we add water to the emptying tank.  This can go on until there is absolutely no water around to go into and out of the tanks.  This is not the case with charge.  There is an entire columb worth of it stored up in the Earth.  When our tank is running out of water going empty filling with holes whatever charge from the Earth can be added to the oscillator.

thats funny that you use water as an analogy here. one of my basic demonstrations of "OU" that i give to people when they try to hit me with all this "thermodynamic b.s.". i take a large tank of water with a small hose at the bottom, and use the pressure to shoot a tiny stream of water into a small tank, higher than the original tank.,
them let it drain back from the upper tank into the lower one, and show them how that can be used to gain excess energy, while still maintaining the same water in the lower tank at the end of the cycle.

electricity is much like water in many ways. with the right kind of "nozzle", i suspect you can charge a 2nd capacitor to a higher voltage, but less potential (F), then the power can be utilized, and fed back into the original cap. though i wouldn't know how to actually "do" that......
