Now try to use those machines to power something else like a generator or a pump. They won't be able to because there is no excess energy to tap off. As soon as you put them under load, they stop working. The fact that for most of the video the guy had to keep moving the magnets in his hand shows that he had to put extra energy into the system to get it to turn. That's not free energy or perpetual motion. Even the last machine needed energy to start the process, but I suspect it is just another free energy trick machine that conceals a motor and power source inside the drum since the speed is constant. Physics doesn't work this way.
