The search for a machine which moves on its own, forever, is almost as long as any ridiculously impossible quest in science.
Now another denizen of the internet thinks he's getting close.
Gizmodo points to the 'Calloway V Engine', which uses magnets to power itself.
No, it's not a perpetual motion machine. The magnets will eventually lose magnetism, and it is likely that the machine would slow down well before that as friction increases in the moving parts. As ever, you can't beat physics.
Still, it's a neat device.
"The V Track motor will work by lifting the stator magnet above the sticky spot using a ramp cam mechanism. But the lever on the bottom plate raises a magnet by the same cam to assist in pulling at the start of the V magnets on the rotor wheel. The mechanical gate assembly is also supported by a spring which assists in lifting the gate."
Though he later adds:
"Where am I? What does it mean to say: the world?... Who tricked me into this whole thing and leaves me standing here?...... Why was I not asked about it?"
So make of that what you will.
