On the mk8 there is 16 coil i need one , to get 100 volts rectified dc. one coil connected on a 470uf i get 35 volts in 3 sec.

my guess is ~100 volts in ~10 seconds.
at 16 feed that would be ~100 volts/~47 milliamps per .6 second.

would be more then great if we could go milliseconds...

@ Jeanna:

That was a very good explanation of the JT construction, thanks for putting it up here.  I will add one other thing that might help folks that are having trouble with the circuit.  As are most small transistors, the 3904 is very easily damaged (destroyed) when soldering if you don't use a heat sink.  My soldering iron is only 24 watt and I have fried several before I dug out my heat sinks....since then no problems.  Just thought I would add this as a possible problem/solution for folks.  Of course, if you are using the breadboard method like Jeanna and a lot of us, then this does not apply.

The cap size can do that 47 uf , Or am i wrong .

I guess i am saying it depends on what you will run from those caps.

One man knowing , is vulnerable , many many people ,that is a different thing, I need many replication , many understanding .

I'm replicating away. I have tried dozens of configurations since I've gotten involved in this. My limits right now are time and parts. As I get more stuff and try different things, I'm learning quite alot. I've built a working MK2 with the 4 tertiary coils on a ~1 inch toroid. I did a detailed post a while back. Just one of the dozens of things I've tried. I just recently tried a coil on a ~5/8inch toroid with bifilar 2x27 turn Primary and Trigger with a single 54 turn Tertiary. I rectified the Tertiary to get 20 volts from a ~1 volt Alkaline AA. I'll be making a detailed post about that some time. I've also used my 555 timer circuit to charge batteries or run my MK2 JT from. I've got a circuit in mind that I'm working out in my head to use a double 555 timer circuit with voltage sensing to drive a JT circuit with a fairly large toroid (2in+, 5, 6..?) when I can get a hold of one. I'll then use the Tertiary coils rectified to drive classic JT circuits that have smaller coils all identical then rectify all in parallel or series to charge, make light, power lasers, power electrolyzers, whatever.. All the toroids I have to test with are 2x~1in, a ~5/8in, ~1/2in, 2x~1/4in and I have some more 1in coming from ElecGoldmine. One goal of mine is to rewrire my house lights to a seperate circuit with motion lights and timers and drive this system using solar+wind to charge batteries that will drive the JT circuit LEDs put in place of my CFLs then all my lighting needs will be free the grid and work even when the power is out. Will be costly, but any money put in will recoup in just a few years time. Specially since they have new LEDs coming out that are manufactured on larger silicon wafers instead of the current material which will make LEDs 10 times cheaper in the next 3-5 years. Once that tech is mass produced, ppl will start making the move to LED lighting in houses, especially when new homes are built which would be the easiest time to install such a modification. One days sun and wind should at least give you several weeks of nonstop light with moderate use. You have energy to spare and never have to worry about a blackout putting you in the dark. Run some electrolizers with any excess power and store in tanks to be used later for heating/cooking/hot water needs. I want to be completely off the grid in 10-15 years. Free Energy, Overunity, Underunity, Cheeply Captured Energy, I don't care what it is

maybe it is me who is counting wrong. 
~47 milliamps per .6 second or ~470 milliamps per .6 second ?

a 47uf cap should divide the time by 10, but also the milliamps by 10
