@Group,

Here is my new core and coils. This is a Iron powder core with 2 x 1000 turns 0,2mm magnet wire on the secondary.
First test is run with a 400 turns 0,35mm primary onto a Ferrite rod with 10mm air gap at each side. With approx. 1 Watt
input the output voltage in each coil was approx. 100 Volt. Could not get any current out of the secondary coils. There was
voltage but even a Neon bulb would not light up. The primary frequencies was approx. 20KHz. Next test will be with a air core
coil on the primary with smaller air gap.

Groundloop.

I woke up in the middle of last night and something hit me:

Increasing the output by increasing the turns count on the secondary leads to a dead end because of thicker wire needed (for low resistance) and more turns. The amount of copper would be sky high.

Then I thought about the TPU and Steven Marks's remark on this subject:
=======================
If you had a short wire and you move the magnet across it, you would always
have limited potential because the length of the wire was so short.
Ok, now what if we increase the length of the wire to many miles in length ,
even with a very weak magnetic field moving across the wire you still have a
much greater potential flow of power available.
If we out it into perspective of power per inch, it may be easier to understand.
If you have a small magnetic field moving across a wire 12 inches long, it can
generate an electron flow equal to let?s say 1 milivolt per inch.
If you move the magnetic 12 inches at the same speed , you get 12 milivolts
as you transgress the 12 inches of wire.
Understand that I am trying to convey a principle that you can understand for
use in the future.
So you have a wire 12 inches long, and you can make 12 milivolts moving a
magnet across it.
If you have a wire 1000 feet long and you move the same small magnetic
field across the length of it, you can create much more voltage potential
perhaps 12,000 milivolts let?s say.
So, you have managed to generate a significant amount of electric power
with a weak magnetic force.
Ok, how does this help us? Where am I going with this?
Suppose you have 1000 pieces of wire 12 inches long and you run the same
weak magnetic field over them all at the same time??. You get the same
flow of electrons.
If the wires are run in series , then you will get the 12,000 milivolts etc.
If you connect the wires in parallel, you will get a higher current but lower
voltage.
However, the power potential is the same whether you run the wires in series
or parallel.
=======================

What would happen if there were many parallel secondaries instead of a large series one? What would happen if HF-Litze is used for the secondaries with just enough turns to obtain a nice output voltage. Think of litz with eg. 600 individually insulated strands.

Very true, I said as much myself when I said it's the volume of copper that's most important.

Not sure why Thane prefers hv models but I didn't feel like disagreeing with him any further about how his investion works.

He has after all apparently single handedly done it, assuming verification holds up.

BTW Thane, are you in a position to carry out the 2 tests (mag field and anti series self induction) I recommended or have you given all versions away to Luc and Steve? I am hoping to test them both in the morning.

Hi,
I was thinking about this point Mr.Entropy brought up:

...
It also seems important to balance the loads on the secondaries (use a variable resistor on one) so that their fluxes will cancel.  This reduces the secondary inductance and allows you to draw current more easily.
...

Maybe it is possible to make one load draw balanced power from both secondaries by rectifying the current from each secondary and then connect the two rectified currents in parallel.
In this case the loading of the two equal secondaries should be automatically 50:50:

(I will delete this posting if Thane Heins thinks it is not helpful)

Wouldn't you just put the 2 secondaries in series?
