Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of thermodynamics. In fact, we classify based on WHICH law of thermodynamics they break. We have perpetual motion machines of the first kind - they violate energy conservation - they pump more energy out than they need to keep running. This includes most of the historical devices. Then there are machines of the second kind - they’re a bit more subtle in their wrongness because break the second law of thermodynamics - extracting energy by reversing entropy. Many modern “free-energy” devices fall into this category. Now the best modern designs are by you - answers to our recent challenge question, which we’ll get to at the end. But first let’s take a look at examples of what other people came up with - this’ll be a fun little journey through some pretty terrible science.

Designing a perpetual motion machine has a very long history and became quite the craze from the middle ages through the renaissance. The first well-documented design for a perpetual motion machine was from the 12th century. Bhāskara's wheel, named after the Indian mathematician, was embedded with tubes of mercury that would flow from back and forth as the wheel turned. Other types of over-balance wheels followed through to the Renaissance and worked on the same principle. There were also designs that employed the magical-seeming lodestones - magnets. For example, this ramp in which a ball is pulled to the top by a magnet before falling through a hole and rolling to the bottom again. Then there are the self-pumping waterwheels or self-blowing windmills.

“Actually, quantum mechanics forbids this” he’s becoming self aware

Quantum mechanics forbids a lot of things...like time travel and by extension, faster than light travel!
It also forbids people to learn more about itself
Good meme
I came to comment this
You want infinite energy? Just place down a redstone block smh.
YUP 😂
This joke is underrated
I rather plant trees, turn them into charcoal, create a machine that will plant trees for me, make more charcoal, then make a machine that will cut trees for me, get infnite charcoal, then get a machine that will burn trees for me for charcoal. FREE INFINITE CHARCOAL! Perputum Charcoulum.
Only 13 block range though. Or 7? I forget.

The hardest part of writing a TH-cam comment is figuring out whose quote to use
The way I see it, we should build a Perpetual motion machine of the 5th kind.
If it succeds, we have a perpetually working machine.
If it fails, we discovered the 5th law of thermodynamics.
It is a win-win enterprise.

Disobeying the laws of thermodynamics?! That's a paddling.
To set something permanently spinning, simply strap a slice of bread and jam, which we all know will land jam side down, to a cat’s back which we all know always falls paws down therefore two opposing forces fighting each other for superiority. I found through experimentation that apricot jam works best especially when strapped to a Siamese cat.

The fun part that gets looked over is efficiency.. the energy gradient of the modern car compared to the first internal combustion engine is so vastly different is like watching gravity driven power compared to the space shuttle. I'm amazed at how they do not fire up imaginations with the challenge to build things that take much less to perform better
Totally agree. Was thinking the same as i was watching.
You can approach an efficiency of unity by getting closer and closer. Going beyond unity to actually get anything out of it isn't natural, sorry, won't ever happen.
@@nathanwahl9224 To add to the injury further It is actually proven that you cant even "reach" unity.
@@sayamqazi No kidding... That would be called a "perpetual motion" device, and we all KNOW that's not possible
Yeah, the modern ICE car has gotten all the way up to somewhere between 25% and 35% efficient at turning gasoline energy into motion. Not bad for nearly 150 years of refinement.
The Laws of Thermodynamics:
1.) You can't win or lose. You can only break even.
2.) You can't break even except at Absolute Zero.
3.) You can't get to Absolute Zero.

The quest for a perpetual motion machine is itself a perpetual motion machine.
What if the real perpetual motion machine was the friends we made along the way?

P.S. Yes i spelt that exergy and not energy, for a reason.
Im at work at devising a machine to capture the energies.... heat... mechanical.... etc.... released from a lying politician's mouth. One great part about this approach is the degree of freedom afforded the user in selecting which politician they want to hook up to the device. Once I complete the prototype I intend to test. Though I still have some engineering challenges to overcome..... in principle I am very optimistic that I will have created a perpetual motion machine that greatly exceeds in energy output compared to any energy input required. Will keep everyone posted on my progress.

I’m fairly certain that if a perpetual motion machine was ever created somehow, it would probably just function as an inefficient battery.
If it moved fast enough, and was bigger with a couple more next to it, it'd make a good generator for a house.
Planetary orbits are a sort of battery. You could in theory sap angular momentum from them to power something else.
@@ghaldurinanubios4290 But where would the energy come from? When I posted this comment, I was thinking it would essentially act as a kinetic energy battery. That kinetic energy would then be possible to turn into heat and electricity. That electricity could then be used for a bunch of stuff

I thought I had created something that could generate energy. But years later after my prototype got smashed at the school fair, I looked into it and realized that the excess coil of wire was using heat from the sun where I had set up to create more energy like a solar panel could. i was so excited for a long time after busting a few bulbs thorugh excess energy generation. Now I realized I was creating a loop of electricity through infrared.
But you coudln't convinced me of that when I was just 13 years old.

Perpetual gravity can be harnessed . An under water wheel using 12 airbags with 12 weights outside of them. Can be made to turn using gravity alone. Only enough air to fill 6 of the bags. Weights will move towards gravity's pull = from the top towards the axial. = from the bottom away from the axial. Taking air with them through the wheel from the top to the bottom bag.(accordion style). All the full air bags are on the same side. Gravity will spin the wheel... till patrs ware out.

In the 60s I visited the Franklin Institute in Philly! They had a swinging pendulum about 3 stories high which kept swinging because of it's alignment with the earth's equator, and the earths rotation kept it swinging! Of course, any hookup with work would eventually slow it to a stop!
All Foucault pendulums run down eventually because of friction, unless they are powered somehow. They precess because of the Earth's rotation, but they cannot extract energy from it. Most are powered by an electromagnet near the top of the cable.
The second law does not state that "entropy can _never_ decrease," only that entropy _tends_ to increase. 3:08 The fact is that is can indeed run in reverse, for short periods of time, it's just so rare that we don't tend to consider it.
Let me guess. Quantum?

Livin' to Learn If you look in the upper right corner of the clip you will see that there is thanks and credit given. It would have been impossible not to realize the source video was itself also debunking perpetual motion.
Ah, yes, zero point energy. The guy I worked for 20 years ago was an analog engineer and he also was a patent examiner on the side. I remember long conversations on the phone where he would have to carefully explain to various inventors why their energy extraction devices wouldn't work. They tried to avoid saying the word 'perpetual', but basically that is what their patent applications usually amounted to. Reverse-entropic devices.... for example, trying to extract usable energy from johnson noise, and stuff like that.
There were inventions that passed his desk that did produce energy... just not very much, and most of the inventors didn't understand physics well enough to know where the energy was actually coming from... but thought they had something wonderful when what they really had was a really inefficient solar panel or thermal gradient device.

I almost feel these quacks should be celebrated a bit instead of ridiculed. It takes a lot of effort, imagination and drive to create these things. However their creations unfortunately just add to the anti-science wave of moon landings, flat earths, global warming, antivax, etc.
Every once in a while I go down the TH-cam "free energy" rabbit hole. On rare occasions I can get someone to understand there is no energy in magnets to extract. Mostly, they just freak out and call me names. I only wish "big oil" would pay me to point out the obvious in comment sections.
Yeah but you probably didn't try attaching flywheels to the electromagnets, that's what did it. The laws of thermodynamics will stop being true if I add enough physically confusing pieces to my grand design.
There is a third category which is neither thermal or PV, it goes back to crystal sets and you can get a measurable amount of power from a truckload of antennae and tank circuits with a cats whisker type diode. Basically you can get a few microwatts out of each one.
@@scotthammond3230 I hope you mean moon landing deniers and global warming deniers.
I remember being about 15 years old (1983) drawing out my blueprints for a perpetual motion wheel using electric magnets and whatever else I could find in my Grandfather's garage. I actually thought I was onto something.
This was well before the internet was around to show me how little I knew about basically EVERYTHING.

@@d_9696 Gotcha. I thought that was part of his original video.
The impossibilty stems from the approach, everyone focuses on the machine part of the problem.
When one focuses on modifying perpetuity then the problem becomes a great deal easier to solve.
Even the Carnot cycle doesn't necessarily have an efficiency of unity. If I recall my thermo correctly, a Carnot engine's efficiency is dependent on the temperature of the heat source and heat sink.
Efficiency = 1 - Tsink/Tsource
At Tsink = 0K or Tsource = infinityK, the efficiency will be 1. For any other cases, efficiency will not be 1. A Carnot engine could even have an efficiency of 0 if Tsink = Tsource.

@@seemlyme
I'm not entirely certain how you hope to assemble this. Or why you think this would work indefinitely. It is possible to make the float of a fill valve work in reverse, so to speak, that it closes up a valve the lower the fill line gets. But then once you get past that it becomes dubious.
Firstly, this is the wrong type of valve for such a process as, the second the moment the inverted fill valve whose valve is shut off by the float as the water level lowers as opposed to rises, the bladder will begin to fill again. It would be better to simply let the pressure between the gravity-fed water tank and the pressure within the bladder equalize, and then seal it off with a valve that isn't dependent on the level of the water, or seal off the bladder at some semi-arbitrary point prior to the bladder bursting with an independent valve.
But then we get the issue of attempting to spray the water back into the tank. As the bladder begins to drain, the pressure on the water will shrink and any free-jetted water will have a weaker and weaker stream until it can no longer be fed back into the tank.
"The manual actions should be automated and repeated then perpetual motion"
As the machine you've proposed doesn't have any way to automate them, you will need to automate them from an outside source which is energy loss. Additionally, this machine is what this video described as a "type 3 perpetual motion device" where it can theoretically feed itself indefinitely, but does no work outside of that. The water being sprayed through the air or the water being fed through to the bladder would need to interact with an outside system in order for it to do work.
The failings of your proposal are:
1) Improper valve usage
2) dependence on consistent pressure in a variable pressure system
3) It is a perpetual motion machine that does no work besides to feed itself.
4) It cannot even feed itself.
"I keep designing perpetual motion machines. Ironically, I can't seem to stop."
I forget where the quote comes from though, sorry.
Sounds like something Groucho Marx would say.
Or, Marty Feldman.
Smart as he was, Groucho left school at the age of 12. His early 20th century audiences were also unlikely to know what perpetual motion machines were; what is special about the idea. It can be hard to appreciate how ignorant people of the past were of simple mechanics; certainly they did not know laws of thermodynamics. Whoever made that joke was certainly more modern.
-Ronald Weasley
Even if you know it is impossible, just go on.
Most of the things we learn, is more because we fail, rather than success.
When I was at school, a friend and I. We invented Perpetuum mobiles and discussed them with the physics teacher. They worked in that perspective that the teacher always said to us that our Perpetuum mobiles will not work because of this and this physical law. A law we did not learn until this point.
Best episode ever, Matt. ❤
I consider incredibly slow loss in energy to be close enough to perpetual motion for being a cool toy
like the sun is near enough infinite energy to stop the winjing and tap that keg
Like when someone makes an m machine that takes the power of a magnet and just releases it really slowly over time since magnetism power last so long I would consider these
Yup. It wouldnt make a difference if it lasts a million years or infinity to humans.
The ebb and flow of tides is the easiest macro scale oscillating energy system. Why is everyone trying to chase what the moon and earth already provides?
@@misaelolvera2996 Nobody has made such a machine, because they're mathematically impossible. Magnets don't have power. They do not release energy. You can't run anything on them, because they are not power sources.
Think about magnets like springs. The spring can push on something, but only if you compress the spring first. So the energy you get out of the spring is just the energy you put in when you compressed it, minus some losses. It's exactly the same with magnets. There is no arrangement of permanent magnets that provides a sustained net force, just like there's no way to arrange springs so that they'll continually accelerate a wheel.
The reason electric motors work is because they move the field itself. There is absolutely no way to make permanent magnets do what electric motors do, because their fields are static. And once the device has reached its minimum energy state, it will simply stop. And the magnets will make you stop faster, because they'll induce eddy currents as the moving magnetic fields pass through conductors, sapping energy from the system and dissipating it as heat.
Seriously. Trust the physicists on this one. The whole "make stuff spin forever with magnet power" is bullshit.
"Actually, quantum mechanics forbids this 😂👌"
I am ded.
perpetual motion forbids this joke..
All this video did was convince me that I want to make a cool looking toy thing that goes for a long time
The closest we’ll ever get would still be impossible because of gravity which ALSO creates friction because it’s inevitable that separate parts will be touching another. Also all and any device must be balanced for the least loss of energy BUT then again that allows an equal balance distribution of energy made and energy used which cancels itself out.

@ViperDaniel Where in quantum mechanics says this is forbidden? There is NO SUCH THING as time in quantum mechanics. Quantum mechanics believe time is an emergent property. An any kind of MOTION machine requires time for motion, as such quantum mechanics doesn't say any such thing that this is forbidden.

If perpetual motion was possible, physics would break. The laws which would be broken would have terrible implications elsewhere. Such violations of these laws could open the door for other, unforeseeable things; like a creature which never needs to eat, photosynthesize, or look for chemicals.
The Carnocycle actually gives the barest inkling of an idea; room temperature air is brought into the system from outside a room and compressed to create a high temperature zone to power an engine, then once the heated cylinder has "cooled down" to "room temperature", the compressed gas is released into the outside world where it is functionally "very cold", but will disperse eventually due to the sheer volume of "room temperature air" as well as being warmed by solar rays or possibly geothermal radiation. This process would essentially be a "very inefficient solar engine".

12:07 I thought the quote was somthing like "how man vankai mirrors have you pursued?" And I went to look it up with a few different spellings until coming back to see the CC and found out what he actually said 😂
Would you say that perpetual motion machines will be perpetually proposed?
The universe would need to be a perpetual motion machine to do that. Stop dark energy from spreading everything out and then maybe we can talk about it.
@Adam George The universe is only estimated to be 13.8 billion years old, so we're still "near the very beginning of infinity". Keep in mind that you can only exist to observe the universe during the time period during which it has low enough entropy to support your existence (ie, relatively close to the beginning).
But as for the rest of what you said, no, motion doesn't "stop". Energy will always exist in the universe, it will simply be too spread out to interact with other energy after a while. It will still exhibit quantum behavior and experience changes in its trajectory that keep it from being "perpetual motion", but some form of motion will always exist.
As the heat death of the universe approaches, i imagine sentient creatures will still try to formulate something like that.
@Adam George Infinity doesn't exist.

So superconductivity makes perpetual motion machines possible huh? Horse shyt.
While it is unlikely verging on impossible for anything to reach 100% efficiency all the attempts at a perpetual motion mechanism did create highly efficient systems. Which is incredibly useful.

There would also be friction in that machine. There would also be head transferring through the axle.
As someone with no background in physics, i disagree. Here, let me explain. See what you do is...
The interesting this is, trained scientists have trouble thinking outside the box they are put in. If they start off from the position that something is impossible, then they will not try to do it. The person to find this, if it IS possible, will end up being the person you are ridiculing. Rather than mocking them, treat them like children and pat them on the head and say, "Keep trying". If they succeed we all win, right?

Well, get a generater to start a big microwave producing machine that steams H²O 🌫 and turbines turn creating electricity.
A electricity substation off to the side regulating the ⚡and the generator that started the microwave steam machine, can then get its own ⚡from self giving electricity to keep microwaving and steaming turbines that make the energy.
Cool the steam to recycle itself back thru the machine and still have a water supply from nature to use as well.

Likewise, the Fontus evaporative water condenser (the project has now gone bust). It relies on the ground always being cooler that the air above (also high local humidity, which usually doesn’t result in deserts, which is why hot Florida isn’t exactly like the Sahara Desert). However, by the water vapour giving up its latent heat of evaporation, the soil around the unit will soon warm up until there is no temperature gradient.
It will 𝙎𝙏𝙊𝙋. Because the "starting force" go to end up, it will not increase but it will decrease during the process, , it mean : the process( the cycle) will finish( end) soon

@@solargoldfish i dislike the video cause of that.
I was going to mention that he did a video debunking pmm's. Hilariously
That video is very funny, it did show it blow up in the clip, so hopefully people saw it was a joke.
TL;DR I've never noticed it before, but PBS has been one of the biggest educational institutions of my entire life. It's "done it's job" _so_ well, for so long.
I *really* don't want to come off as patronizing. This channel really does make me proud of PBS. I'm so astounded by how well they've adapted to TH-cam. This content in particular almost feels like it's evolved with me, in a personal way. When I watched PBS as a kid, it was stuff that was just complex enough to actually be educational.
Then cable came around, and I assume they had more freedom to challenge their audience, so while I was a young man, I remember learning new stuff. Even though I spent most of my life at a school, I learned.
Now as an adult, who spent endless hours as a teenager watching physics specials and nature documentaries, I'm still being taught. I've learned from what they taught me, and now they're teaching me something else. Like they're keeping track of what I know. That's what I mean by it feels personal. They're SO SO SO good at their job, bless them.

1:48 that one is so stupid it's actually hilarious 😂, why would the ball fall throw the hole, a magnet strong enough to pull it up isn't gonna let it fall
I gave that a thought for a moment. I don't know you are right. The ball is being pulled up a ramp. That requires less force than to hold it against the direct pull of gravity.
Best part of thinking that you know how to make a perpetual motion machine is that at some point you realize is not posible and you get to really understand the Second Law of Thermodinamics.

Ericsson's caloric engine is a nice 19th century example which was actually built and used to propel a ship. Now the engine worked... terribly badly because Ericsson thought he could magically recycle heat without losses through an exchanger
It works because you supply it with heat. Hence the term "caloric".
Even if you can't create a perpetual motion machine, creating a 10.000 years motion machine would already be pretty good right?
You need extract that energy from some thing, "Equivalent exchange young alchemist"
That’s kind of the point that I get confused about with all the people who just want to debunk perpetual motion. What I find most interesting is the passive energy generation and the challenge of making an efficient system. Even if you could have a machine that could charge your phone at night, that would be awesome.
You refer to perpetually motion visual display. A low energy input is needed, lowering energy loss is good
Absolutely not. We must stick to the rules, perpetual means forever. What use is a perpetual motion machine that only runs for 10,000 years? /s
10 year semi perpetual motion machine sounds pretty good as long as it looks cool
The best proof that entropy always increases is that if the opposite were true, perpetual motion machines would gradually invent and build themselves.
With nano threading throughout the whole vehicle all light or other energies can be captured used or stored as well.😎👍
Our goal shouldn’t be trying to create a perpetual motion Maschine, it should trying to create something that’s close to one, which is possible
This pursuit is called engineering.
Genuine
So what you are saying is fusion power
@Jacob Turnbaugh Thats simply not true. Did you watch the video? Perhaps things are perpetual in the theoretical entire expansion and contraction of universes. If the expansion reverses and all the energy expended collects back into a black hole, and the cycle perfectly starts over again, then you are correct. But we don't know that, therefore you are just wrong. Planets slow down over time, suns burn out, hawking radiation, heat radiation, vibration slowing inertia, etc etc. Please explain yourself.
@Jacob Turnbaugh Nope. Magnets lose their efficacy over time mate.
I hate that its Not possible, Imagine how cool it would be, it needs to be patched.

And don't hit me with "oh the government controls the internet" Because if they did then you wouldn't be posting about how the government has tech like this.

Alex The Air Monk damn you must be real fed up with these conspiracy theorists
Two questions. If something if functionally perpetual does it count? Like if it lasts for 1 billion years.
Second what if you can create an pocket environment with different physics. And create a perpetual motion machine that works in that environment. It takes mass energy to maintain that environment but within it the machine works. Does that machine count or do you classify " the machine" as the device AND the environment
My idea was a improvement of the magnet fan motor trick. Has the second pair of magnets comes around, a cam shaft pushs the magnet out of the way preventing the magnetic back repulsion that stops most of these things. reason it wouldn't work is because to much energy might get lost in between camshaft pushes
This has been tried OVER and OVER with zero results

What if the magnet ramp design had a magnet that spun to face the other way as the magnetic ball came up the ramp on rollers, or a switch. The rollers or switch spin a cog wheel that spins the top magnet to face the other way just before the ball drops. The ball drops on a lever with gravity that also spins the magnet back to pull it up again magneticly. Then you have the exact same setup facing the opposite direction. So when it pulls up a magnet from the other side it spins again and so on going back and forth to each side. Almost like a horizontal 2 stroke design. Ramps each way like the diagram in the video but facing back to back to each other.
I’m intrigued by the use of a siphon to move water uphill… always have been.
Siphons don't move water uphill, they move it downhill by routing it over a hump to create negative pressure. Trees and plants and even dirt itself can move water uphill via capillary action.
A siphon HAS to have more downhill than uphill, or it would cease to function
I invented a perpetual motion machine when I was a kid. It goes as follows. Get a hose and form it into a circular loop so that the two ends join. Half fill this loop with a magnetic liquid and mount the loop so that it is upright (like a big wheel). Also inside the hose place a small hollow ball so that it floats on the liquid on the left side. Now place a large permanent magnet near the loop on it's left so that the liquid is pulled towards it and now only fills the left side of the loop. This will take the ball to the top of the loop which will fall down inside the hose on the right side (with no liquid). When it reaches the bottom inertia will make it enter the liquid at the bottom and once inside it will float up to the top through the liquid. Then when at the top it will continue to move to the right (the empty side) and will then fall down again, continuing forever. I know it doesn't work, but can you see why?
Sure. The ball would NEVER penetrate the liquid hard enough to start rising through it on the left side, it would simply stop at the bottom. Gravity would make certain of that.
@@davelowets Almost right. You could have enough enertia to penetrate the liquid, but once inside the liquid the flotation action is pushing the ball to the right, not up (as the magnet is on the left and displacement forces are right pushing), so the ball will be pushed straight out again, and gravity will help it stop as well. So even though it could enter the material it would end up sitting at the bottom of the tube just outside the liquid.
@@petejohnston5880 If the ball is non-magnetic, the magnet and the "magnetic liquid" would have zero effect on what the ball does. It would simply be gravity overcoming the buoyancy of the ball at that point, and preventing it from completing the cycle.
@@davelowets The ball is non magnetic but if it's in the liquid and the liquid is being pulled to the left by the magnet, then the ball is being pushed to the right (to allow the liquid to fill it's space). In a normal liquid the ball would rise to the surface but in this scenario the ball is being pushed to the right (when inside the liquid) and has no upwards forces.So with enough momentum it can enter the liquid it's just that it will be pushed straight out again and will never rise.
I invented a perpetual motion drone. It was too good and flew away. It's still up there somewhere....
Lol
That's unfortunate..
That reminds of a science fiction short story I read some time ago, where the guy accidentally invented a ball with a super-unity bounce ratio. That is, if you dropped it from 100 cm high, it would bounce back up 102 cm. Cute story, spoilers, it proved to have disastrous consequences, particularly when it was bouncing miles and miles into the sky, each bounce was like a meteor impact, and they couldn't figure out how to catch the damn thing.
I think it just flew by my house
My physics teacher had a fit of laughter when we were building machines based on perpetual motion machines, we were seeing of everyone in class who's machine ran longest, my teacher thought this year he has something that could potentially become a PMM. I said to him before you build a perpetual machine, shouldn't you first find perpetual materials to build it from.
My concern exactly, I've wondered about ideal building materials for decades.. the design doesn't matter if it is still subject to degradation
I wouldnt want that teacher
Great video

I love how this video bassically just takes a huge perpetual crap all over everyone attempting to make a perpetual motion machine. Haha!
I'm glad people are still trying. Will it ever amount to a perpetual motion machine? Well no. But maybe we'll get some cool new data from their attempts!
he defined perpetual motion as a system that runs with no external energy input ... then he demonstrates a machine that receives no external energy input and chooses a PORTION of that to say it is not possible ... like taking a carberutor from and engine and saying it cannot create enough power to move a 1 ton vehicle ... well duh of course not the carb is only a PART of the system .... he made the worst mistake in science possible he removed logic from his rebuttal and got it wrong ...
leave the carb in the system turn the key and poof the engine works and moves the 1 ton vehicle ... using a portion of a system to refute its claims is BAD SCIENCE .... and that gets taught in the first week of all science classes ... guess he skipped that week
Assuming a positive cosmological constant, isn't the expanding universe the ultimate perpetual motion machine?
@Es D Negative wouldn't work. It's been shown that you'd only get a limited number of Big Bang / Big Crunch oscillations.
@@ravenlord4 yes but... the universe itself isn't bound to the laws of physics. Only the matter and evergy is on a local level.
The real question here is: in an expanding universe, is energy conserved? If so, how? If not, rethink your laws or decouple them from your assumptions about the nature of the beginning/end of the universe. Because on a cosmological scale the laws of thermodynamics are fanboy trash.
The universe is NOT perpetual.... it has an end.
@@ericalbers4867 ~"On a cosmological scale" is the only place where the laws of thermodynamics ultimately apply.
On a human scale it only matters as an equation of efficiency.
But until the last proton decays some billion trillion years in the future, the laws of thermodynamics ARE on a cosmological scale.
Jerry VanNuys is an icy eternity spent getting closer and closer and closer and closer to absolute zero....an “ end”?
Could someone explain to me why a brownian ratchet wouldn't work if there was a vacuum on the gear side? I'm sure it wouldn't, but I just don't know why it wouldn't.
Trying to create a perpetual machine is the best school of physics. James Watt dealt with this subject several decades before ending up with the steam machine.
