Long-Duration Motion Machines

Long-Duration Motion Machines are hypothetical devices designed to operate for extremely long periods without external energy input, while still respecting known conservation laws and thermodynamics. Unlike perpetual motion machines, they do not claim infinite operation or energy creation. Instead, they rely on ultra-slow energy dissipation, delayed equilibration, environmental energy harvesting, or probabilistic and extraphysical mechanisms. The key distinction is that long-duration machines eventually stop, while perpetual motion machines violate physical laws by claiming endless motion or energy output. These machines are often discussed in theoretical engineering, speculative physics, and borderline scientific proposals.

Long-Duration Motion Machines — Example

A hypothetical machine uses ultra-low-friction components, cosmic background radiation harvesting, and delayed thermal equilibration to keep moving for millions of years. It never produces excess energy and slowly loses motion over astronomical timescales. Unlike a perpetual motion machine, it obeys thermodynamics but exploits environmental and probabilistic factors to extend operation far beyond conventional machines.

Pull a Durant

To take the easy way out. Can also relate to being Lebron James' bitch

Example 1: I can't beat the Warriors,so I'll join them and lose all my dignity in the process

Example: I'm 23 and still a virgin, I think I might pull a Durant and call a hooker

Alonso Horros Duran

Is one of those types of guys that will suck the life out of you when dating him. He doesnt care if he hurts his friends or anyone around him. All he cares about is himself. He will date you, then cheat on you, try and break you and your current boyfriend apart, then try and get back with you. He is a coward. Cant even muster up the man hood to talk to parents. He is a sketchy POS. Even little boys are more manly than Alonso. The best way I can describe him is he is a BLACKHOLE. Everything around him gets sucked into nothingness.

Person 1. Can you have Alonso Horros Duran talk to your father?
Person2. Nope he is too much of a coward!

Murphy's Law of Engine-Idling Duration

"If you leave your vehicle's engine running during a delay in proceeding (traffic-jam, road construction, accident-resolution, "stuck" red signal-light, etc.), you will be sitting there for many minutes, just wasting gas. The instant you turn the key off and climb out of your seat to stretch, however, THAT'S when the line of traffic will begin moving again, and thus you will have shut off your engine "for nothing", AND you will now be holding up everyone behind you while you hastily hop back into the driver's seat and re-start the engine so that you can move forward again."

I finally took da plunge and bought a second-hand Toyota Prius because I'd eventually had one too many cases of Murphy's Law of Engine-Idling Duration... the Prius automatically shuts down its power during stand-stills, and then uses its electric motor to provide instant mobility as soon as you're ready to go again.
