This one is intresting.

pix,  sorry that didn't work out but thanks for trying.  Although there were strong indicators at least from my perspective that this was a scam
we never know for sure without trying.   It's just that nearly all youtube vids on free energy are scams and when you see one person or channel there
posting a whole lot of different devices claiming free energy then there is a very good chance it's fake.   That particular poster had videos that were clearly
fake although the one you replicated was fairly extensive in it's deception.

The last youtube video I saw which seemed a real OU device was Pierre's device discussed here:  https://overunity.com/17609/170-watts-in-1600-watts-out-looped-very-impressive-build-and-video/

Hi,

I just finish and test my car alternator...

On rotor are magnets 30x10x10 N35
https://www.ebay.de/itm/233951477802?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

When I run it with drilling machine on 2500rpm I get 8V of alternate current... I dont know how much wattage I get... i must test...

so far for now...

I told You guys, trying car alternator is not going to give impressive results.
Because active length of stator coil sides  "l" interacting with rotor magnets is not long.
Induced electromotive force E=lBVsin alpha
My modified 3 phase motor is much better, gives 170-200V depending of rpms.
It is very important to figure out windings configuration on the stator and position magnets properly, so at the same time one coil side is cut by N pole and other by S pole of rotating rotor.
Otherwise , if you mess it up induced voltages in separate coil will cancel instead of adding up.
Also air gap between rotor and stator is cruicial, so precise machining is important.
Rough designs done with a instant glue having air gap much more than 1mm are poor efficiency.
8 Volts @ 2500rpm is too low, something wrong in your design.
Typically , properly done car alternator will give 40-60V max.


Cheers,

PS.
It is worth investigating which design is better, and this will be my next task for 3 phase motor:
a) opposite magnetic poles cutting active coil sides  , according to Faraday formula E=lBVsin alpha. This design implements number of magnets= number of poles x number of phases. For 4 pole motor gives 12 magnets on the rotor  N-S-N-S.....
b) opposite magnetic poles cutting coil loops, according  to formula  E=dB/dt. In this design magnetic pole width = individual coil loop width.  In 2 pole motor (3000 rpm) that would be 2 pole design of magnets on the rotor  (N-S), in 4 pole motor ( 1500 rpm) that would be 4 pole magnets design on the rotor(N-S-N-S)

Why do you say the alternator for cars are not efficient ? Without diodes, the car's alternator is a 3 phases alternative power.

Because:
1. It was already tried by other guys. There is a forum dedicated for a wind power projects full of topics and projects  for conversion of  car alternators, washing machine motors ect. with permanent magnets. And guys report maximum 60V on modified car alternators.
2. According to formula E=BLv sin (alpha) voltage induced in the conductor immersed in moving magnetic field is depending on magnetic field strength "B", length of inductor "L",  how fast is relative speed of movement "v", and angle between vector of magnetic field lines and condictor "alpha".
So, you could see, car alternator is shorter than washing machine motor or typical 3 phase motor- induced voltage will be smaller.
