Will we see perpetual motion machines in our lifetimes?

They're called year round waterfalls.

Zero energy input, endless energy output.

Time Crystals are literal zero point energy that are predicted to last either forever or longer than any other part of the universe.

But no work can be taken from them. Thermodynamics dictates we won't be able to do that. So yes and no.

We already have perpetual motion, but perpetual motion is ironically impossible to harness.

>>8891766
Can someone explain time crystals to me?

t brainlet

>>8891744

Rumor on the street is we are only a few years away from obsoleting all the laws of thermodynamics

>>8891735
wtf man, the worlds water is able to cycle because the sun provides thermal power to drive weather systems & evaporation. Physics and precipitation does the rest.

Do you see Europa or mars with perpetually moving water on it? No, because they're too fucking far away and too fucking cold.

>>8891770
Normal crystalline structures exhibit spacial symmetry, but time crystals express a symmetry through time as well; their structure, in their default state with no energy added, cycles over time.

Since the ground state cycles with time, it appears as if it is moving without energy input. It's theorized that it'll either stay like that for literally ever or slowly stop because of quantum fluctuations in more time than our universe is expected to have anything else going on in it.

The downside is, you can't get any work out of it because it's at its ground state. There's energy to take. It's sort of a grand irony in that way. Perpetual energy with 0 work.

>>8891788
Very interesting thank you for the explanation

>>8891788

Time crystals are currently theorized to only be possible with energy input.

>>8891788
There's no* energy to take.

Had to fix that.

>>8891807
Energy is required in their creation, yes, but currently isn't observed to be required for their maintenance.

>>8891788
hey crazy no-ego man, fuck off with your time crystals.

>>8891928
>Energy is required in their creation, yes, but currently isn't observed to be required for their maintenance.

Incorrect, energy is required both to create and also to maintain. There is a distinction that you have to use periodic oscillations of electromagnetic radiation to create the time crystal but once it's established the oscillations of the electromagnetic energy can be random and the time crystal will continue to oscillate with periodicity.

>>8891727
There are such instances of perpetual motion in nature such as an atom.
However you cannot harness energy from these systems without affecting them and thus causing this motion to cease.
But if you accept current science there are no systems known in true perpetual motion, even the atom and smaller eventually degrades into its constituents.

>>8892024
What happens to atoms when they lose energy?

>>8891788
I guess dividing by zero gives you infinity after all...

>>8892063
The may take on a lower energy configuration, where electrons are in a lower energy state.
Or it could be unstable and break apart. That would be a radioactive atom and it would release its energy as fast moving particles and/or rays

>>8891727
Maybe not in our lifetimes if we don't end up living for ever, but the Casimir Effect can be tapped for extremely minuscule amounts of free energy, its useless now, but as the total heat energy of the universe decreases the eneregy will be more and more useful when compared to the energy of the CMB. So after all the black holes evaporate, the Casimir Effect will be what high tech civilizations use to power their virtual universes at the end of the universe up until all the protons decay (if that ever will happen)

>>8891727
No, because you won't live forever

>>8892168
You just need to live long enough until living forever becomes viable. Once we start turning asteroids into supercomputers (50-60 years from now) we will be able to model metabolic processes and cell aging much better and simulate evolution of proteins which could improve lifespan enough to last until we can begin uploading minds (200-500 years)

Europa has moving water under its surface, Mars sometimes has flowing brine on warm summer days at low elevations near the equator, but is dry usually because its atmosphere is too thin to support liquid water.

>>8891766
No you have to pump energy into them continuously, with a laser I think.

>>8892674
No

>>8891727
Yes.

I work at CERN by the way.

>>8891783
Missing the role of living systems there bud

There's no perpetual motion, but systems can get so good at exporting entropy that they might as well be counter-entropic (see life on earth).

Windmills are literally perpetual motion machines because there is infinite wind.

>>8892674
Only to observe them. They exist without help, but since they don't do anything you can't see anything.

>>8891727
EM Drive has already been invented.

>>8891727
if you could make something that expels energy at a VERY slow rate, then yeah, it'll be "perpetual" throughout your lifetime until you yourself croak.

Not if you want to harvest their kinetic energy, no.

>>8891788
There's so much buzzword bullshit that happens with the explanation of time crystals. In layman's terms, what's really going on is what you can imagine to be two masses connected with a spring. Pull them apart, then let them go. They oscillate back and forth, and if friction wasn't stopping them, they'd oscillate forever. That's what time symmetry is. Just apply that to a lot of particles, with the spring forces being the electromagnetic pushes between them, and you have time crystals.

>>8892089
It's to my understanding that the Casimir effect gathers a negative energy potential between the plates, while output energy occurs outside the plates. It's why it's considered as an agent for the Alcubierre drive; enough negative or dark energy would theoretically lens spacetime in a manner opposite to the way gravity does.

>>8892662
Doesn't mean it has no lower energy states than its existence as an electron. If you try to stop its motion, it theoretically loses its mass but not its momentum, which is carried away by the massless particles it decays into. The loss of velocity just becomes a loss of mass.

Europa gets its energy from tidal heating you dimwit
>Mars has water on warm days

Truly fires thine neurons
>>8893011
Yeah, but in the end your energy source is meat and veggies, your meat's energy source are plants and in the end plants harvest solar energy. It's all solar-powered (though Earth also gets energy from fission).
>>8891772
With crystal energy, quantum willpower or what other arcane bullshit? Mind enlightening us?

>>8891727
>We will get to see something that doesnt make any fucking sense?

Are you an engineer?

>>8891727
the entirety of the universe is a perpetual motion machine.

>>8891727
>will the laws of physics be broken in our lifetime?
no

>>8891772
I would screencap this and save it for a thread in 2020 if it wasn't so mindbogglingly stupid.
