Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

The search for a perpetual motion machine has been the chupacabra of physics for centuries. Multiple designs have been made, tested and, ultimately, found lacking. Perpetual motion machines are ...

In 1986 Leif Hauge's brother had a farm in Norway near the sea and wanted to keep his vegetables cool by circulating water from deep in an adjacent fjord that would flow through pipes and surround a ...

Perpetual motion machines can do work indefinitely with zero energy input. If one existed, it could turn a wheel or raise water, thereby generating energy without needing fuel of any kind—a useful ...

Almost as soon as humans created machines, they attempted to make "perpetual motion machines" that work on their own and that work forever. However, the devices never have and likely never will work ...

Have you ever heard of a Perpetual Motion Machine? More to the point, have you ever heard of why Perpetual Motion Machines are impossible? One of the reasons is because of the first law of ...

A wheel weighted with swinging mallets. A cylinder rotating in a sealed, water-filled container. A siphon that transfers liquid back and forth in a seemingly endless loop. These may sound like the ...
