Idealism #1 Perpetual Motion
If perpetual motion was real, I think it would look a little like this:
It would need an infinite or near-infinite power source, something like solar energy with a constant electrical relay, so it never fails even during outages. To truly be perpetual, it couldn’t lose energy to resistance. That means it would have to move in a perfectly contained system: like a carousel that never stops because friction simply doesn’t exist there.
But then, for it to have purpose, it couldn’t just spin in isolation. It would need to do something, maybe convert that motion into tiny bursts of usable energy.
The paradox, though, is that use creates resistance. So maybe the only true perpetual motion is something that exists but doesn’t try to matter. Maybe motion that serves no purpose… is the only kind that can last forever.
