Why haven’t we found perpetual motion?

"The hardest part about designing a perpetual motion machine is deciding where to hide the batteries."

[CardiniPanini]

If it makes sound, it's losing energy. If it is rubbing against another surface, it's losing energy. If it's *existing and moving*, it's *extremely likely* losing energy, unless you can somehow find an entirely isolated and perfect vacuum. As long as you're losing energy, you can't go back up to any kind of spot that you started at.

Seeing the cat and saying but you’re not supposed to be there. That’s perpetual motion right there.

Whenever you drop the cat on the floor, it returns to the table. Perpetual motion!

”It’s always a trick, otherwise we could stop worrying all the time.” Is a good way to summarise how significant it would be. It would solve all our problems.

[TheLastCrow]

People need to realize that our problem isn't making energy, it's storing it...

He clearly has never heard about buttered cat levitation

The hardest part of a battery is hiding the perpetual motion. True quote.

"you shouldn't be up here though" is said by cat owners on a daily basis.

[SonicRicky]

I remember seeing an ad for a perpetual motion machine that also mentioned the length of the electrical cord

[MCKoolperson]

Even hypothetically, if you were to create a perpetual motion device, it must be silent. Any device that produces sound is by definition, not perpetual motion.

[GKnight]

The internet: "Oh my god it's perpetual motion!"

*Friction, Air resistance, hidden batteries*

[niravdarmesh]

Steve Mould has a video about this device; in which, as Steve is wont to do, made a transparent version of the contraption. I mean, you can tell exactly what's going on, by, if nothing else, by the sound made by the ball traveling along the track. However, that being said, I enjoy every individual one of your whyfors.

I used to think you could have perpetual motion in space without gravity until I learned thermodynamics. Boy was I wrong.

"It's magic!"
"It's actually magnets."
"How do magnets work?"
"Uhh... magic?"

[TheodoreDubinsky]

If it looks like magic, it's magnets.

That cat. That cat right there.
✨️Absolute purr-fection✨️

It blows my mind that people can see things like this and not be able to figure it out themselves. Or at least conceive of how it might work. You'd think the clearly metal balls and thick base would be a pretty big apparently not.
