Okay, I had a look now at the original video,
but unfortunately it is not much better in quality.
Anyway, the
schematic connection picture already posted is right.
http://www.overunity.com/index.php?action=dlattach;topic=7679.0;attach=35467In the first experiments there is no cooler grill connected.
Just one ground connection to the water pipe !
(maybe they have the burried cooler grill connected in parallel with the
water pipe, so it gives them a better ground connection ?
Could have been out of the video area, so you only see once the
connection to the water pipe...)
So it seems to be a pretty easy circuit.
Just some sort of Tesla coil, looking to be 2 coils, one with many turns
and the second with just 6 turns,
where the first many turns "high voltage coil" is
energized by the green box with high voltage pulses ( bursts)
via the spark gap and then the output of the high turn coil goes to the
light bulb bank(all bulbs connected in parallel) and then back to the
low turn 6 windings coil and then to ground.
It looks like they are pumping somehow the free electrons from the electricity from the ground
through the bulbs and then to the attracting positive pole at the spark gap.
Maybe they have been canceling Lenz law in their special series circuit of this
special Tesla coil ?
The black box with the 4 cables is just a special impedance transformer with a rectifier circuit in
there to transform a bit of the output AC power back to the
inverter DC input.
Thus they really achieve a selfrunning circuit this way.
The light blue metal box seems to be the inverter from 12 Volts DC to 220
Volts AC.
It seems to be a dual function device which could probably also
act as a battery charger cause it also has a nonconnected 220 Volts
connection cable attached to it, which is not used in the video.
But the battery charging is not used in the video, it just only
acts as an inverter to transform the 12 Volts DC from the battery
to 220 Volts AC.
This video is really challenging, cause it really shows a selfrunning
system putting out around 500 Watts of free electrical power just
plugged only into a water pipe as the ground line.
Amazing !
