Here is a video from WaxingRadiance that shows magnet coil relationships

I don't think there is any relation to the event propagation direction. The output of the coils do not benefit the next event coil. However, the magnet getting closer to the next event coil ( generator) induces a current, that generates a field, that might interract with the previous event coil. Sadly my magnetic field simulator is NOT able to simulate this amplification / elimination of new magnetic field and the NEW interrcation with the neighbour coils.
Considering the large gap RomeoroUK had between the coils, i would expect it to not have a considerable impact. HOWEVER, he did mention that he tried both pull / push motor configuration, and the pull one seemed to work better, maybe because of this event propagation effect ?
If this is so, then the distance between the coils (coil sizes + magnet sizes ) might also play a key factor in the whole device.

Nice way to auto-balance a rotor is a trick I learned from dismanteling a PC CD-DVD -drive.
Sony patented a very simpel auto-balancer that is often mounted in a clamping mechanism of a PC CD drive, due to the high speed recording options these drive have (up to 10.000 rpm and higher!)

The construction basically consists of a hollow track centric to the rotation axis that is filled with metal balls. The track is only filled partially.

If this is mounted on a unbalanced rotor the balls will tangentially position itself such that unbalance is compensated when rotating.

I used my test setup to test the double diode bridge setup like in the video demo from Lidmotor. My test setup currently has just a single coil with a neo magnet rotor driven from a fan motor. With no core in the coil and a red LED as load, I could see the marked rise in voltage effect reported by Lidmotor when I connected the additional diodes (which were silicon type) to the bridge rectifier. With a ferrite core inserted, the effect substantially reduced and with a 1K resistor as load, with and without the core, no rise in voltage was observed. This effect varies considerably with load and coil core type and in all my test configurations, the loaded output voltage was always a lot less than the open circuit voltage, which does not appear to be the case with Romero's setup.

I applaud Lidmotor for taking a step by step approach to gain an understanding of the likely operation of Romero's device, before attempting full replication.

hi everyone,
Before to start with mass of serious experiments using high spinning wheel with heavy magnets ...
please take a break and make at least some acquaintance with common physics,

to be honest I do not care so much about your balls ... oh dear, of course very bitter 
I do care about your younger brother or son surely wide-eyed looking near the table

cheers,
