Okay, here's one for you guys...

We build a transformer that has two primaries and a single secondary.
One of the primary windings has many turns for accepting a high voltage
input.  The other primary winding has only a few turns of thick wire
for accepting a high current input.  The secondary winding we will have
to calculate the turns and wire size based on our needs provided this
half baked idea has any merit.

With each primary winding we calculate its inductance and connect
a capacitor to one leg of it and a power source to the other leg, then
from the other capacitor leg to the other power source leg.  So what
we have are two series resonant L/Cs with mutual inductance via the
transformer core.  We adjust the capacitor values so that both L/Cs
run at identical or nearly so frequencies.  Each power source is
relatively low wattage--one high voltage; the other high current.

If we can get this far without running into some kind of physical
impossibility, what would the secondary see?

Based on transformer turns ratios, this scenario is a bit of a mind
screw for me.  We have step-down which should increase current
and we have step-up which should increase voltage.  Best I can
tell, the secondary should only see the changing magnetic field in
the core and be oblivious to how that field got there.  So what I
wonder is, would the secondary only see the combined wattage
from the two input sources?  Or could it see some multiple?

Then suppose we have two separate cores with the secondary
wrapped through both of them.  Would it still behave the same?

Again, half baked idea yes, but what I'm striving for is some way
to take advantage of turns ratios where the weakness of one
power source is made up for by the other power source.  Maybe
it would require some kind of switching to lock the current in
the core as the energy transfers between L/C components.

Could be a chicken and egg problem where we do not know for
certain what the dependent and independent variables are.  And
of course, it's not nice to fool mother nature.

Here’s another one for you guys

I found this in some of my old notes. At the time I didn’t make note of the originating author but I think it was Matt Jones at Energetic Forum. It’s one of those things I never got around to trying.

For DC currents

… Yes they can be summed together from 2 different sources. But it has to be done in the same time . You cannot charge a cap with high voltage then charge it with low voltage at a higher amperage. Both the amperage and the voltage must discharge at the same time.

The key is how to mix them.

You can accomplish this by adding an equal bridge rectifier to the output of both the generator and the motor. Then you serialize the 2 bridges. This keep each power source independent of each other…

… So if the motor is dumping 100 volt at .01 amp and the generator at the same time is dumping 2 volt at 4 amp, granted they do it in the same time frame, and you serialize the outputs (NOT COUNTING DIODE LOSS) you have 102 volt at 4.1 amps.
Just like 2 batteries in serial…

I ran into a snag with this. I don't know how to affix ring magnets to the shaft, so I started to look for pot ferrite magnets.

It seems I am not very able to find, here in UK, pot magnets that are axially magnetized.

First4Magnets told me that "all pot magnets" or at least all their pot magnets are diametrically magnetized, and unfortunately I cannot use these.

I watched the Borderlands experiments of Lindemann/Knox with the homopolar generator and it's clear : if the pole that passes thru the vicinity of the external brush is changing, we get AC.

And AC is incompatible with the voltage pump experiment. Not sure, but most likely. Think I have to know for sure which direction the current flows to know which direction I to pump voltage towards.

Once I find those bloody pot magnets (yes there seem to be ones with GuysMagnets at 50 mm, but I want the 100 mm version) I can get on with the experiment.

I am quite hopeful that it *should* work, as there won't be two power sources in the same circuit, but the same coil will be inducing at the same time the amps from the homopolar rotation, and the voltage, as the back EMF at the end of the pulse. Looks to me that if both electromagnetic phenomena happen at the same time we should have a sort of a fusion, volts added to amps, as Lindemann said about Rudolf Steiner's theory - that electricity is an unnatural combination of the warmth aether with the light aether.

Another thing I don't know - people start telling me the homopolar generator exhibits Lenz drag...
