Touch that picture if you want to see the device from different views.
This is an idea from a fren, who's been wondering about Bessler PM.
The main idea of the device is to change the gravity of the mooving iron ball, becouse of the small magnets above the track. As you can see from the picture, the ball is rolling on a track, that is fixed to the pendulum. When the ball would trie to prevent the pendulum oscilating it comes under the magnets (red). The magnets reduce the weight of the ball. When the ball comes in a position where its mass is useful, there are no magnets above it, so it accelerates the pendulum.
