Hi, I do not think the setup works as shown, my red flag is he did not show the rear side of the 'working' setup (he showed it in a separate video, when the setup was stationary, see below the link to that video.) However, let's say I give the benefit of doubt and consider it as not a fake setup. Let's say the 12 rotor magnets are groupped by two (and there are 6 groups): say NN directly next to each other then two SS comes and then again two NN and so on. See my attached snap shot picture. I base this on this starting picture where you can see the hinged big magnet is the closest to the rotor wheel and when he removes the stay-rod he does not rotate the wheel to any direction, this means that the two rotor magnets should repel the facing hinged magnet so that the latter backs away from the rotor wheel. And this movement should make the spring a bit tensier but not too much and then the attract forces from the two next rotor magnets should come together with the just tensed spring's pullback force. I indicated a "Cam point" where the cam shaft is fastened to the smaller rotor wheel: at the start up moment the 'cam point' is already above the rotor wheel shaft, and very near to this 'cam point' the end of the spring is also fixed to the 'cam shaft'. My speculation needs to be analyzed of course. My other speculation would be that the hinged magnet is a pot magnet and in this case the rotor magnets may have alternating NS sequencies because then the circular edge of the pot magnet is say a N pole and the center part of it is an S pole. In the other video where his setup is shown also from the rear ( https://www.youtube.com/watch?v=3212eb41gaY ) the hinged magnet can be seen much better and looks like a pot magnet, its rear edge is round and its front edge is sharp. His third video with the water bottles https://www.youtube.com/watch?v=fpHfTXXVLlE is surely a fake, such setups have never really worked in a genuine way. Why did he show this third video, makes no sense, youtube channels include lots of fake setups like that. Gyula
