Perpetual Motion

[Anonymous No.10589733]

>These laws of thermodynamics apply regardless of the size of the system. For example, the motions and rotations of celestial bodies such as planets may appear perpetual, but are actually subject to many processes that slowly dissipate their kinetic energy, such as solar wind, interstellar medium resistance, gravitational radiation and thermal radiation, so they will not keep moving forever.

What kind of goal post moving mother fucking definition is this? "OH, IT ONLY LASTS TENS OF BILLIONS OF YEARS, SO IT'S NOT TRUE PERPETUAL MOTION."

Mother fucker, if we built a machine on earth, the metals that it's made of will turn to dust in millions of years, so that doesn't make it a true perpetual motion machine?

I don't understand what's hard to get there. It's quite an easy thing to understand actually.

There is nothing wrong with "perpetual motion." If you spin a flywheel in a vacuum, it will basically keep spinning forever. This is just a consequence of Newton's first law. The problem comes from when you try to extract energy from the flywheel. So basically:
Perpetually motion=physically possible
Free energy devices=physically impossible

>an object in motion stays in motion
>a.k.a. perpetual motion
I can't even tell what you autists are arguing about. A system that is perpetually in motion isn't a "perpetual motion machine". No no no no no it has to look like it was built by willy wonka
