This is just stupid for so, so many reasons.

I upvoted so that anyone with a brain could have a laugh at those who believe in perpetual motion.

It's kind of a clever one, but his hand is providing the input energy. If it really worked, he'd bolt the magnet to the baseplate and walk away. It depends on subtle oscillations in the force on the ball (i.e. tiny oscillations in the distance of the magnet). It may not seem like much, but the energy to provide that is substantial relative to the energy necessary to rotate well machined bearings.

Or, like every other perpetual motion cheater on the internet they just have some form of ducted air blowing across the top of the device.

They ought to have prisons where the prisoners learn remedial science all day long so they can send the perpetual motion nuts along with the dwfttw, young Earth, Intelligent Design, Ayn Rand, and all associated believers along with the climate change deniers there until they can pass a basic science aptitude test.

The world would be a better place.

Damn you! On this website, we obey the laws of thermodynamics!
