The coupling between the coils is very complex. To solve a general case requires knowing the mutual coupling between each coil and each other coil and the source and load impedances. This creates an array of simultaneous equations which have to be solved. This is usually too complex to do be hand and needs to be done using special programs in a computer. But if all pickup coils are identical and all of their loads are identical, then the current will be the same in each pickup coil and the sum of the energy in all the pickup coils will be less than the energy going into the primary coil. I do not know of any simple explanation that will make this easy to understand.

Maybe I can help here a little bit.  If you power the JT circuit from an earth battery, then it is OU in my opinion...or free energy, whichever you choose to call it.

I will attempt to do more catch-up on the other topic tonight.  Thanks for all of your patience. (Finished my taxes today!!!!!!!!!!!!!!!!!!)

Hi everyone,
I thought it was time for a little light entertainment. So, I dug my MK1 out of the box.
I re checked and changed the way I was connecting the wires, I have a good amount, but according to both the rectifier and the scope, I have less than the cap collects.

The bridge rectifier which is much more satisfactory than the one I bought ready made some months ago, says I am getting
38.9VDC after all the rectification. This is close to what I got in January when I made this MK1.
The strobe says
25V going up and
24V going down.
Since I still don't know where to connect it I tried a bunch of places, but the highest is with the probe on one wire end and the clip on the other. I don't know where else to put them. I reverse these for the different direction waves.

Then I put the cap cut out from the AAA fuji ckt in place between 2 more diodes and collecting from the - and + of the bridge and wow I got 110 volts in the cap.

My goodness, where did all that voltage come from?

By the time I pushed the shutter it had gone down to 95 so I can't prove it with a pic. But I can prove 95 volts even though it was 110volts when I first measured it .

have a look.
The blurry labeled pic is the one with fuzzy details of how I set it up. But you don't really need to know that, I think.
The crisp one is taken from a 6 inch tripod sitting on an overturned cooking pot. Ha, (I know what a cooking pot is for!)

Ok well a bit of a topic change I am working on my fuji mod and can light a 4 watt tube just fine. However I can not light my Christmas lights? Its 100 mini lights, the type you get from wal-mart. Anyone have any ideas?

Thanks!

They have to be LED lights.
