and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

I have remade the Nexus diagram as requested by Luc with the changes

adding every single diode made the image far too complex so its just image and description changes

the blank area on the left may be large enough for a parts list when we get the info

@Luc

please delete the image if anything is incorrect... I wasn't sure about the half wave bridge rectifier as on the original it said 3 to 5 1N5408 but you mentioned 4 diodes in series so I drew the diodes in the same direction as on the original and drew the diodes like the others to show them in series

EDIT: changed font error and size of image

Great job Aka ;)  looks good to me!

If anyone sees anything else that is not clear or what ever please let us know.

Thanks Aka for this great job.

@Gotoluc,

Thanks to you and everyone for the great work.....

On the nexus circuit, the only correction needed would be on the cap is it AC or DC ?

@bwb, @gotoluc,

You do not need any resistors at all. Just make sure to use enough number of diodes in series
so that you never are near the maximum diode voltage for each diode. Design for worst case.
Nexus uses at least 60 diodes (800 volt type) in series. I use 37 (1300 volt type) in series.
Bot diode strings can handle up to 48 000 Volt. If we say the car ignition voltage is 30 000 volt
then; 30 000 / 60 = 500 Volt for first case and 30 000 / 37 = 810 Volt for the second case.
So in both cases we are nowhere near the maximum diode break down voltage.

Groundloop.

Hi Greg,

I have two questions about your circuit if you don't mind.

What is the purpose of the diode across the + and - terminals of the ignition coil? Are there different effects with it and without it?

Hi,

The coil is a nasty inductive load.  The diode is an ultra-fast recovery diode that protects the Triac ... or Mosfet ... whichever is used.  Whenever a coil is driven by a transistor, no matter what kind,  it's good practice to use diode protection.  Some call these "free wheeling" diodes and sometimes come integrated in standard Fet components.  Almost all loads can exhibit inductive characteristics, even Capacitors.  There's one across the charge Cap also.  It's just protection and has nothing to do with the 'water spark plug' or plasma effect.
