I have never heard of that one, but it sounds like a classic perpetual motion device.

Some of our fun exercises in physics class involved reading about real perpetual motion devices that have been invented in the past, and figuring out why they wouldn’t work. Some of them are not obvious.

99.999% of them won’t work because of friction

The theoretical “frictionless surface” in physics classes does not exist in reality
