Hack - 220V Electric Generator from an old Washing Machine Motor DIY - Universal Motor to DC Generator conversion with full explanation , wiring and connections.
He creates an electric generator from a PC fan, magnets, and using a transformer he powers a light bulb. But supposedly, the generator is autonomous! It does not require any mechanical force to rotate.
Clearly, it's bogus. I have not tested, but such a permanent movement does not exist. Mainly because, if I remember correctly, this type of motor works by induction, and this creates a force that opposes the movement. And the action of the magnets does not change anything since they also have a repulsive effect and block the rotation as much as they cause it. So at best, we can have something that runs a little longer.
Yet in the video, it works quite well to shine a light bulb. So good, with a pulse why not, it can turn and generate a little current. But there, the rotation accelerates under the action of the magnet.
In a second video by the same author, he recreates the experience and announces a generated power of 2500W... the device is connected to a power strip on which he plugs light bulbs in series, and a heat gun requiring 2000W of power, and that he turns on. And it works (well it seems).
How can a permanent magnet generator (of VERY SMALL magnets) put out 2000W of power? If P=U.I, with the hardware he has, it's impossible. Moreover, one could produce such power with another device, but certainly not without mechanical work.
