Just to be sure, you are actually shorting the DC o/p cap BEHIND the FWBR and the cap voltage does not get affected at all and the current to the load doubles ? You shorted manually?
That's actually the 2 stage extraction strategy that Doug has developed, where he would do it non-reflective to the source with MOSFETs.

Correct. Shorting on the DC side of the cap across the load. My test was to see if shorting will create those high voltage spikes and improve anything. I think it is not really improving anything. If it is creating those high spikes they are being absorbed by the cap and used as current. More shorting bigger the load therefore higher current extraction but not necessarily towards the load.

I will be testing more shorting in different points just to see what happens.

Fausto.

I did a test today where I would short the output cross the buffer cap (cross the load) and I noticed that I can double the amount of current without affecting the output voltage and very minimal impact on total RPM.

I am shorting the cap at around 20 times each with a duration of 100 microseconds.

Fausto.

Are you using an arduino? Is the code available?

Hi Mo.,

first of all, thank you for sharing so much information!

You seem to read a lot of this old, rare EM stuff. Just recently i read "Magnetic Current" by Ed Leedskalnin (again- because of this thread ) and i was wondering if you ever tried to improve the magnetic fields of your coils in covering them with a iron/ferrite pipe (and closing the flux-path between core and pipe with another iron/ferrite ring). Ed wrote, that you almost double the magnetic "particles" (travelling in the iron, activated by the magnetic particles escaping the copper of the coil) in doing so.
I do not know, if it only applies to the motor coils (which you do not have), because it probably does not work "the other way round" with generator coils, when the maximum amount of magnetic particles in the coils are already activated to travel as current out if the winding(s). So no improvement then in trying to increase the amount of magnetic particles in the iron surrounding the copper which push the magnetic particles in the coil.
Just coincidence, that it would be in line with J. Newmans theory, which says, that increasing the mass (turns) of the coil increases the magnetic field of a coil (using same current), according to the formula of the strenght of a magnetic field?

I can imagine, that it is quite difficult to modify the coils. I just want to point you to something which is probably worth a try...

Also i want to point the builders at a statement of Mr. Adams (-Motor): The geometry of the coils (specific width/height ratio) is essential.
Can not recall, but something like 4:3 or 3:4 - which i did not find at any of this (monster-) thread pages...


Kind regards,

uu

The ratio was 1:4 )

uu, sorry but I have not read "Magnetic Current".  And I have not really played around much with gen or drive coil design.  I am quite a novice at this.  But others have done such experiments for quite some time and may be able to share some results.

Edited to add:  @Hoptoad comes to mind.  If he hasn't tried it I would bet he knows someone who has!
