Nope, it's faked. Using Newtons' laws of motion you can prove that to make it to the top of the loop it needs to be dropped from 1.5 times the height of the loop.
Every roller coaster engineer knows this.

Whaaaaaa?!?
There’s fake stuff on the Innerwebs?!?!
When did this happen?

There's an Alnico 5 magnet assist just off camera. A ceramic magnet won't work.

Many people believe pendulums are perpetual motion, and when you try to explain that whole friction / resistance issue to them, they like to bring up cuckoo clocks as evidence to the contrary. 🤦♂️

But if you dunk your cuckoo clock in peanut oil…

That’s just plain weird.

Not perpetual, rather perceptual: "relating to the way people interpret and understand what they see or notice"

The closest I've seen is a display at Costco. Outdoor lights powered by solar panels that were positioned under one of the lights. Continuous lighting.

Still won't work, there are losses in the wires and the solar cells. It may run for a long time but it will eventually stop working unless you add a battery to cover the resistance losses. |

Um, not sure I agree, the solar panels produce current, not consume it. There will be a voltage drop due to the resistance but not a current drop, and the resistance will be a constant unless physical changes occur to the circuit, so the voltage drop will be too. Ohm's Law applies. Solar panels work really well on spacecraft for decades. |

Ohm's Law applies. Solar panels work really well on spacecraft for decades. Yep, because the solar panels on spacecraft have external energy coming in...from the sun. That's not a perpetual motion machine. The example tahitijack gave implied that you'd have perpetual light by putting solar panels under lights that are powered by the solar panels. The reality is that, in the absence of outside energy added, that won't work. The solar panels would not come close to capturing all the power consumed by the lights plus there'd be losses to heat etc. |

Even with fresh batteries AND a solar panel. |
