AC is a DC polarities "timed" changes.
you push electrons to one side then push them back to where they started in a given period of time.
no matter whitch way you push them, you are doing was is called "positive work"

I think you may have meant to say, an Alternating Current is nothing more than a Direct Current in which the "direction" of current flow alternates. That is, the Direct Current flows in one direction and then in the next instant reverses it's direction--- it Alternates. As well it should be noted that physics has proven long ago that the electrons in a conductor move at a snails pace and have little to do with the actual transfer of energy in electrical systems,the energy is in the associated electric and magnetic "fields".

@All
I think we should also understand how this is relates to measurement on our oscilloscopes. A sinusoidal wave (AC) such as domestic power 120v@60Hz will show a rise above zero volts to 120v then back to zero,then below zero volts to negative 120v then back to zero volts. But it should be understood that this is not a "negative" potential voltage, the portion below the zero volts line is where the current has alternated---it has reversed direction because the polarity of the source has reversed. What some call a "negative" voltage is in fact a reversal of voltage polarity which is always relative to the "zero" line(center horizontal line). Our oscilloscopes essentially measure a potential difference or voltage and polarity between two points in a known period of time. This gives us no indication of instantaneous power because power in Watts is volts times "amps". We can test this process by connecting our oscilloscope probes to a battery, note the voltage relative to the zero volts line, then reverse the probes on the battery and note the voltage relative to the zero volts line.

@Resonanceman
I think I have a couple of solutions to increase output.

What I am working on is  collecting flyback  pulses  from  JT coils
There are not a lot of ways to hook up the coils so that they add together .....

I have been working on a series parallel circuit to beef up the output of the  JT in current only.
My theory is, the JT output streem can be presented to as many secondary (separately wound) toroid's as you would want to put into the circuit.
By paralleling the outputs you double up the current available from each toroid.
For example only, if 1 secondary after rectification is a .5amp, then having 10 separate secondaries
wound on 10 separate toroid's will give a total of 5Amps.

The primaries are "all" connected in "series" the output secondaries be rectified with full wave bridges, all these bridges + & - outputs be coupled in Parallel.

Another way would be to have a JT output presented to all the primaries in parallel, then make an identical second stage as I described in the above sentence.

Yes there will be losses, as in any system, but I hope to minimise that.
I have presented the following jpgs before.

I made a clear schematic of the Dummy.


Edit Electicme i think you will get better result if all toroid in series are wound in opposite direction , so you don't get back waves , this should help get more out !

AC

Hi AC,

That was my point about seeing ac as a 2 way dc. It is the other way around. Until we change how we look at this, we will struggle to get great results.

DC is a very small portion of a larger energy that pulses throughout the cosmos. It is great to use it in our computers and to make batteries that give it out. But AC is where all the power of the universe is. I want to find out how to use it. Tesla left us some information.

thank you for your comments,

Thank you. It is very clear.
