E2rf4n 8: I thought of a giant "drinking bird". The idea doesn't work very well. Here is why: The top of the structure is cooled by the evaporation of water. This means it is at the "wet bulb temperature". The bottom is at the ambient temperature. The temperature difference sets the vapor pressure difference. This is what lifts the working fluid. When the drinking bird turns horizontal, the passage between the vapor in the bottom and the vapor at the top is open. When vertical, the passage is closed. As you make the structure taller, the height difference for the liquid does not increase. This means that above a certain vertical dimension, the power falls. If you increase the other dimensions, the volume of liquid that moves does increase. However the speed of the drinking bird action greatly decreases. The surface area of the bird grows more slowly than the cross sectional area. Thus the heat transfer is less efficient.
What evaporates the water? heat! heat starts the cycle, if you put it in a freezer it will not start because because there is no heat.If there is no water in the glass the cycle would start but would be unable to complete the cycle, the heat provides the energy to tip the bird forward and the water removes that heat, the bird swings back and the heat starts the cycle again. You need to understand it is heat that provides the energy to start the whole cycle.
+Robin Powell It will also stop when the air humidity reaches 100 % as no more evaporation would take place. +SW6 There is still a lot of heat in a freezer. You would need to get to 0K to have no heat which is impossible in itself. But the bird won't work in a freezer because the liquid in the bird would freeze.

No, they got it right. Or at least righter. "The power source is the ambient heat of the room" is the sort of misconception that you get if you take the concept of "there is no such thing as cold, just absence of heat" too literally. More accurate would be to say that it is powered by the temperature differential and particularly the evaporation of the water.
The thing that's powering it is the liquid in the bird heating it up, causing it to rock. The only reason it gets to the water is because the liquid in the bird is heating up, not because of the water itself
I have a perpetual motion machine, I type a perfectly reasonable and respectable sentence into a RUclips comments section and it generates an infinite number of people across the globe to type something vile and offensive back.
LoveTheseCurves Ah, your device didn't work as expected. Only 2 of your subjects came, and it seems the first one was a paid actor. YOU'VE BEEN *DEBUNKED!*
It's no use. Believers will still say things like: "well, maybe the laws of nature are wrong" "science hasn't discovered everything yet" "maybe there are some laws out there that we're unaware of" "you have to be open minded"
That's why it's not enough to say "goes against the laws of thermodynamics", because people like that would, sometimes not entirely unreasonably, not understand just how big of a statement that is. On the other hand, it is also probably a waste of time to go into great lengths to try to explain to those people just how much the laws of thermodynamics encompasses and why they are so wrong in questioning it.
To be totally fair, it IS true that science hasn't discovered everything and that the laws of nature could be wrong. I am extremely skeptical that perpetual motion machines could be built, but I won't say I am 100% certain. Everyone thought Newton's laws were the end-all be-all of physics, but Einstein proved that not to be the case.
Millitron - Your statement is not entirely true. Einstein did not disprove the law of gravity, rather revolutionised our understanding of the mechanism (theory of gravity), completely different concepts. As far as I am aware, no law of physics has ever been overturned. Theories change and adapt all of the time sure, but of course, that is their nature after all.
Out of these, I still have respect for the bird one, it may not be a perpetual motion machine, but still gets its energy from a creative source rather than just a battery.
Homer Simpson: This perpetual motion machine is a joke. It just keeps going faster and faster. Lisa, get in here! Lisa Simpson: Yes Dad? Homer Simpson: In this house, we obey the laws of thermodynamics!
Small correction : the energy for the drinking bird is not the water. The energy is the heat of the room. Of course, the heat capacity of water is helping to exchange that energy more efficiently. When water evaporate, that is when a molecule of H2O happen to vibrate so violently near the surface that it leave the liquid, it rob some of that vibrating energy from those molecule which remains. Somehow, the vibration of the remaining liquid end up to be lower than it would at that same room temperature. It was nice to show that the bird stopped moving when it was in the glass cover. It would have been nice if you explained why. Is it the hot air prevented to reach the bird? Is it the humidity level too high to prevent evaporation? Finally, where do you find these toys. Everybody mention this drinking bird for the last 40 years, but nobody has one and no shop sell anything like that.
It's actually not the heat, but the relative humidity of the air in the room. The air and the water may be the same temperature, but as long as the relative humidity of the air is below 100% there is potential energy in its ability to absorb more evaporating water.
There's this one kid who hid the hidden power source really really well. He basically used the radio frequencies from radio stations to power a led. It's cool, definitely. But not infinite energy.
technically on the bird, the water isn't tree power source, it's tree temperature differential between the water and the air. Brady Harren recently did a video where he made it move with a hair drier aimed at the base, creating a similar differential.
close, but wrong! there is no temperature difference between the water and the air. and the power source is the heat of vaporization in combination with unsaturated ambient air. the vaporization enthalpy will cool the head down below ambient temperature and it will warm up again as soon as no more water evaporates. so the water in the glass has the same temperature as the ambient air. as soon as the air is saturated, the effect will stop.
The device with the power source in the circular base is one of many examples of an "executive desk toy", a product fad that started in the 1980s. They're just intended to be interesting to look at; I've never heard of them being promoted as perpetual motion devices. Even when they were new on the market, everyone understood there was a battery in the base.
To be fair, SOME of these "perpetual motion machines" are just VERY efficient machines that will last a long time without losing very much internal energy. These are usually the more elaborate ones though. If you can get a machine to 99.9%+ efficiency, then it will last quite a while without a power source.
alasyon as a guy with photosensitive epilepsy, if you're really tired or have some other reason you would be more susceptible to a seizure it can cause it at lower frequencies. It's just much harder to.
Always look for the energy source. It might be temperature difference (either direct or caused by evaporative cooling), or it might just be a battery. ;)
i find it very unscientific how people think the "laws of thermodynamics" are 100% undeniably true and should never be questioned. we created those laws so there may be some odd way it could be wrong. most likely not and all of the attempts at perpetual motion are just wastes of time....but i imagine if we got power outside of our universe, like if you got access to the console in a video game, you could "spawn" energy at your will. that would be outside of the laws of thermodynamics of course, but i still find it bad that people assume its 100% true, when almost nothing is 100% for us. however i'm even more annoyed by all the perpetual motion nonsense people spew....so whatever.
It's not that the laws are 100% true and undeniable. It's that over hundreds of years they haven't been false even a single time, despite that it has been tried to break them. The only logical thing to do is ASSUME they are true until an observation that they are false happens.
The laws ain't 100% true. They are true until proven wrong, which nobody has been able to prove or even theorise with something doable (big warning here: something that we don't have the technology to make but work on paper could be enought to prove it wrong. But something that don't even work on paper, like monopolar magnet, will not). So until anybody can prove that the theory is wrong, then it is true.
Rinoa Super-Genius The laws are always 100% true because the laws are observations (words, not equations) and based off one another. In your scenario where you get energy from another universe there's no breaking of thermodynamics. You're getting energy from somewhere and using it, energy in = energy out + waste.
, "But something that don't even work on paper, like monopolar magnet, will not" I think that magnetic monopoles actually DO work on paper, i.e. they are theoretically possible, but never observed in the real world. According to Wikipedia: "notably the grand unified and superstring theories, which predict their existence" en.wikipedia.org/wiki/Magnetic_monopole
There is not always a hidden power source, sometimes they just start the thing with some speed and it has low enough friction so that when they say that it is getting faster you can't really tell if it's true.
Johnny, no, a machine that works for a long time is not perpetual motion. There's one in London featured in one of Tom's videos that's been going for over 100 years. The first law of thermodynamics doesn't specify a time limit, just that it must stop at some point, unless more energy is put into the system.
You're talking about the rolling ball clock, I believe. You know, the one that turned off when there was a city wide power outage in London. Tom even says that in the video you're referencing. It was powered by electricity.
"thousands of perpetual motion toys that really work forever." Um... Did you even watch the video? There are zero perpetual motion machines that "work forever." Literally none. It is impossible. Why is that so difficult for some people to understand?
The way I think about this, is not “there’s always a hidden power source” (but this is true); I’ve always found it more intuitive to think “there’s ALAWAYS a source of resistance (not necessarily electrical... pls read on) that’s “decaying” the work the machine can do, slowly bringing it to a stop. Whether it’s the noise it make when operating (however quiet), or friction, generating friction; or electrical resistance in the wiring; there’s ALWAYS a decaying resistance which brings the machine slowly to a stop.
Robert Williams - I was worried about it too, which is why I counted it. Though I agree with you - the colour change is sufficient to cause a headache!
Its actualy much Easier than you think, a complete basic Perpetual Motion machine is based on the flow of Time. By hooking a Tachyon Infused Semiconducting Quarz Cristal to the flow of Time itself via a realively simple crossconnection by 33.31 Jogus at the rate of 99 Ogol you can archive a 1° Turnrate per Minute alsongside the the line of the two points furthest of the Cristaline Stucture. Then connect the Cristal to some Gear so that the Rotary Axis of the Gear Aligns up perfectly with the Rotationary Axis of the Cristal. Then hang said Timegear into a kind of Stand and have it rotate its way. Hook up as many things you want to as the only Limit is the Structural Limitations of either Cristal and/or Connection Gear. It even works when Time Flows Backwards ... just have to avoid it suddenly being Deconstucted by Isolating itself from the Main Timestream without it loosing connection and with that becoming useless. See? Childsplay!
I am already deeply sorry for Spoiling the Fun, exept figuring out what a Jogus and Ogol is ... honestly thats the hardest part. Also not sure if i wrote Tachyon correctly but you know what i mean once you see it.
To me it reminds me of (and I believe is inspired by) Tim Hunkin and Rex Garrod's The Secret Life Of Machines. Similar style of music and presentation, although much less epilepsy.
Well, not really, but there's another problem here. In order for new magnets to be constantly placed in front of the main one, for it to push them away, there's energy required. So, the whole system of you, the main magnet, and the magnets to be pushed away, there's still energy being used, by you placing the magnets there.
MantroX The cat may walk away while it gets dropped. Or if it does work, it will just fall down. And if you attach it to a pole to a generator, the cat will die.
Fact: Using the word “machine” with perpetual motion or energy, will give it a beginning and an end, making it finite. With this new and better understanding of perpetual devices, its meaning will need updating in defining it as finite. This way, these devices or machines will not violate the laws of thermodynamics, laws of nature, laws of physics, makes them patentable. ~Guadalupe Guerra
I had a University lecturer who 'knew someone' who thought they had proved the existence of magnetic monopoles. He called a press conference, and just before he went out to meet them, he spotted the error in his workings.....
It's sad that the videos showcasing these types of gadgets and making outrageous claims of perpetual motion get way more views than these type of videos. People hate being wrong, but a good scientist loves being wrong.
Yeah. In fact, science itself thrives on being proven wrong, because you learn much more from your failures than you do your successes. After all, as Thomas Edison said, paraphrased, I didn't fail 1000 times; I learned 1000 ways how not to succeed.
Yes, it's a heat engine and all heat engines work on temperature differences. In this instance acheiving that difference relies on the phase change of both the fluid inside the bird (ethanol?) and the water, and that relies on the air around it not being saturated and at a sufficiently high temperature. There is a version of this which doesn't rely on a temperature difference though, it uses capillary action to draw water into a reservoir until the bird tips out of the water, then the water evaporates and it tips back in. It works very slowly though, many hours between cycles.
".they just run around a bit.. but they do exist and they do perpetually" That would require 100% efficiency. There is always a loss in efficiency in everything. So perpetual motion isn't possible.
I eagerly await the not-quite-perpetual flock of perpetual motion fanatics to this video trying to defend their relig-- I mean, delusion. Actually, I think I had it right the first time.
It dependes how much energy you put into something.....The Energy you have put into this message for instance is at a set level.we'll call the units of measure Babbles Lets see what returns you get, if it's more than you put in, then that is perpetual motion.
if you put magnets on the drinking bird and a coil nearby in an appropriate position, could you not use the heating/cooling/motion cycle of the drinking bird to induce a current in the coil?
Lets talk definitions. While technically not "perpetual" if the power source was hidden well enough (lets say someone discovered the omni present dark energy, didnt tell anyone and used that) and the power source lasts millions of years, it would appear perpetual and relatively speaking wouldnt we be justified in calling it
Derek McGowan , you said yourself that it's not a perpetual motion machine, so why would we be justified to call it that? A hidden power source is a hidden power source. And if you used up all of the dark matter then the machine stops working.. So, no. I would say we would not be justified to call it that.
Derek McGowan perpetual motion machine isn't really all that good of a name, if you have a machine working with no friction it will move on forever, but it isn't creating energy, a case like that wouldn't be violating the laws of physics. the term perpetual motion machine means a machine that produces energy which is a violation of the laws of thermodynamics which states that energy can't be created or destroyed, just converted from one form to another, also I just want to be clear, physicists aren't dogmatic about the laws of physics, if the laws of thermodynamics are shown to be wrong with sufficient evidence, that would be an amazing result, and i can assure you nobody would be more enthusiastic and curious then physicists, it just has yet to happen and most likely won't
itai alter im speaking of relativity. From our position/perspective (of unknowing of the source) it would appear to be perpetual and all experiments would report it as so. Soooo... Also, yes a stated the concept but i group myself in with those who wouldn't know of its possible source
Also why is it that we dont define the laws of motion as perpetual motion? There is no energy source that i know of that propels the earth through space AND it appears to go on forever though, through the suns energy and incoming meteors and particles, it is gaining mass. So it appear tgat the same non energy that makes it moves increases enough to handle the increasing mass
I understand what is being said about the impossibility of perpetual motion and more specifically perpetual motion as a machine that does work. But are there any designs out there that could be called “persistent” (not perpetual) motion “devices” (not machines) that would move for very long periods of time, without any hidden power source? Any kind of design at all that could be set into motion, move without a power source, and not stop... perhaps for months or years, until critical parts wear out, like bearings or other friction points? Any design at all? I'm curious.
not between the glass of water and the room, but the temperature differential between the base of the bird and its head, which in this case is caused by the evaporation of the water, eventually either all the water will evaporate or the humidity in the room will reach the point where evaporation for things at room temperature will stop, in either case the system will be in equilibrium and the motion will stop because that temperature differential will stop. if you like you can look up sterling engines which are engines that run of temperature diffirentials such as this bird
+ytmoog No. You got it backwards: I'm saying that evaporation creates a difference in temperature, not that difference in temperature creates evaporation.
Why doesn't the magnets pushing a fan thing work? I mean I get that it doesn't, but if the magnets repel and the fixed one can't move then shouldn't the ones on the fan be repelled, pushing the fan?
even though i know it's a ton of lies, i quite like perpetual motion machines. I just think they're cool little desk toy trinket things. Even though i know there's a hidden power source i think it's cool for...no reason.
The water is NOT the energy source. Poor explanations lead to poor understandings of physics which in turn is why these kinds of misunderstandings happen. The energy source is the potential energy that is stored as heat in the room. This heat energy gives air the ability to dissolve a fix amount of water vapor in the air. This creates a vapor pressure differential, which is the force that actually transfers the water vapor away from the birds head. People understand obvious forms of mechanical energy that they can see or detect. They often fail to understand the idea of potential energy which is much less tangible. Therefore, if you want people to think critically about overunity machines, you need to properly address the idea of potential energy and the non-obvious forms that it can sometimes take - such as differentials of heat or vapor distributions.
Tim Harig The water may not be the energy source but it is the energy sink in this situation. The evaporation of the water removes energy from its surroundings and the water vapour escapes with more degrees of freedom storing the removed energy. The drinking bird would still work in a vacuum.
Anthony Khodanian The point is that saying "the water is the energy source" is a poor explanation that is not going to convince anybody against the idea of overunity machines. To explain it to them, you are going to have to relate it to something that they can visualize as having energy. They cannot put water in their car and drive it. They CAN see the heat in a room melt ice. Then you merely have to explain how differences in energies, forces, or pressures can are sources of potential energy that can be exploited to do work. When they understand that, they will be much less likely to confuse heat engines with overunity machines.
Tim Harig How is the water in this situation any different than, say, the gasoline in a car? People often think that the gas is the source of the energy, but its not. Its the sink in a chemical reaction, where the oxygen is the "source". Because only differences in energy are important, it is just as valid to call the sink or the source as the "source" of the energy when using common vernacular. Just to prove my point with math, it takes 204 kJ/mol of energy to break an O-O bond, and 413 for a C-H bond. This then forms an O-C bond which releases 358, and O-H, releasing 476. This nets 217 kJ/mol in total. The oxygen in this scenario nets 213 units, and the C-H actually nets only 4. The energy is from oxygen, yet we call the source the gasoline. There's nothing wrong here.
The drink bird still seems like a pretty good way to harness energy, no? Just get some water and an giant one of those things and you'll have some easy energy, though not perpetual
Vince Lombardi it's extremely inefficient though. the amount of energy it takes to make the bird bob is immense compared to any output and only just enough to make it bob otherwise you can easily stop it with your finger just resting on it. to keep a large one running (like a water pump to keep the head sponge moist) it'll end up costing more than the output. it's way easier to just set up wind turbines and solar panels
Lesson one- there is always a hidden power source. Lesson two- there is always a hidden power source. Lesson three- there is always a hidden energy source. What you should take from this- there is always a hidden power source. Yeah NO SHIT
Is a perpetual motion machine plausible under ideal conditions? (In a vacuum with no friction between parts), or is 100% efficiency only possible with a heat engine
A few years back. I was working at a research and development company. And a person came in trying to sell us an invention that they had bought a stake in. It was a box. That whatever you plugged in only had a draw of 1/2 of the amperage of the device you plugged in. They told us we were not allowed to open the box, and they plugged in a hair dryer, which drue 15 amps And then when they plugged it into their box. The cord on their box which they plugged into the wall. Was split so you can measure the current. And it showed as 7 1/2. Which I immediately called out as a hoax. Inside their box they jumped the ground and neutral, and then taped the ground up with the hot wire resulting in the magnetic field canceling out half of the strength of the magnetic field in the hot wire. As the current was flowing in the opposite direction constantly.
Had this guy at school yelling at me about perpetual motion machines, and tried to disprove him use the first law of thermodynamics yet he was too stubborn to understand. "But the counter weights make the law not matter!"
I don't want a perpetual motion machine. I just want machines that operate for 100 years before running down. Just a healthy lifetime. Next generation can start their own.
Couldn't the swing motion from that second one be used to recharge the battery while also sending power elsewhere? ie one side have a wire to the battery and another to a proper generator?
555 Droid so say you put electricity through a fan the electricity becomes Kinetic since the power is used to turn somethings so energy just transforms it doesn’t run out. Electric energy -> Kinetic energy in a fan
it doesn't "run out" instead it changes medium, to heat, light, sound, kinetic, electrostatic (yes I do know some are double im just simplfing here) and in doing that it gets spreadout. untill someone uses more energy to compress it again into a usefull package, like a battery or oil or wood.
Here is one way to possibly get closer to perpetual motion. Remove friction and wear. Yet when you remove those two things there are still many things that interfere like pressure
Yes, as long as it is in a normal temperature room, and the glass is kept full of water, it will work until the pivot wears out. But you really can't generate any useful work (energy) out of it. You could generate a TINY bit of electricity from it, but you could probably generate more from a thermoelectric pile with an evap cooled side.
Yes, sort of - but really, no. In space an object could rotate "perpetually", but you would not be able to extract any energy from it; because that would make it slow down.

E2rf4n 8:
I thought of a giant "drinking bird". The idea doesn't work very well. Here is why:
The top of the structure is cooled by the evaporation of water. This means it is at the "wet bulb temperature". The bottom is at the ambient temperature. The temperature difference sets the vapor pressure difference. This is what lifts the working fluid.
When the drinking bird turns horizontal, the passage between the vapor in the bottom and the vapor at the top is open. When vertical, the passage is closed. As you make the structure taller, the height difference for the liquid does not increase. This means that above a certain vertical dimension, the power falls.

The bird one is interesting as it's power source is not so much "hidden" as not normally understood.
It's power source is the heat in the room, their explanation was completely wrong.
No because once all the water evaporates the motion will stop, regardless of the heat in the room.
What evaporates the water? heat! heat starts the cycle, if you put it in a freezer it will not start because because there is no heat.If there is no water in the glass the cycle would start but would be unable to complete the cycle, the heat provides the energy to tip the bird forward and the water removes that heat, the bird swings back and the heat starts the cycle again.
You need to understand it is heat that provides the energy to start the whole cycle.

On the other hand, it is also probably a waste of time to go into great lengths to try to explain to those people just how much the laws of thermodynamics encompasses and why they are so wrong in questioning it.
To be totally fair, it IS true that science hasn't discovered everything and that the laws of nature could be wrong.
I am extremely skeptical that perpetual motion machines could be built, but I won't say I am 100% certain.
Everyone thought Newton's laws were the end-all be-all of physics, but Einstein proved that not to be the case.
Millitron - Your statement is not entirely true. Einstein did not disprove the law of gravity, rather revolutionised our understanding of the mechanism (theory of gravity), completely different concepts.
As far as I am aware, no law of physics has ever been overturned.
Theories change and adapt all of the time sure, but of course, that is their nature after all.

The Royal Institute + Tom Scott! Made my day
Out of these, I still have respect for the bird one, it may not be a perpetual motion machine, but still gets its energy from a creative source rather than just a battery.
Homer Simpson: This perpetual motion machine is a joke. It just keeps going faster and faster. Lisa, get in here!
Lisa Simpson: Yes Dad?
Homer Simpson: In this house, we obey the laws of thermodynamics!
Haha, classic. That was so unexpected from Homer 😂.
Also Homer; It's drinking the water!!!!
Small correction : the energy for the drinking bird is not the water. The energy is the heat of the room. Of course, the heat capacity of water is helping to exchange that energy more efficiently. When water evaporate, that is when a molecule of H2O happen to vibrate so violently near the surface that it leave the liquid, it rob some of that vibrating energy from those molecule which remains.
Somehow, the vibration of the remaining liquid end up to be lower than it would at that same room temperature.
It was nice to show that the bird stopped moving when it was in the glass cover. It would have been nice if you explained why. Is it the hot air prevented to reach the bird? Is it the humidity level too high to prevent evaporation?
Finally, where do you find these toys. Everybody mention this drinking bird for the last 40 years, but nobody has one and no shop sell anything like that.
Christian Gingras I used to see them in novelty stores all the time
The bird did not move below the glass cover because it was impeded by it to move like a pendulum. You can buy the bird online.
It's actually not the heat, but the relative humidity of the air in the room. The air and the water may be the same temperature, but as long as the relative humidity of the air is below 100% there is potential energy in its ability to absorb more evaporating water.
My physics teacher: How does your machine work?
Me: There is a hidden power source
It's DRINKING THE WATER!!!
only scrolled down to make sure this comment was here.
It's my birthday. Nice present

There's this one kid who hid the hidden power source really really well. He basically used the radio frequencies from radio stations to power a led. It's cool, definitely. But not infinite energy.
The energy source for the drinking bird is not the water. It is the thermal energy in the air, and a bit from radiation from your studio lights.
4:37 Hidden power source... REVEALED! Big fan.
technically on the bird, the water isn't tree power source, it's tree temperature differential between the water and the air. Brady Harren recently did a video where he made it move with a hair drier aimed at the base, creating a similar differential.
Sam the energy was Transferred through heat
It's a heat engine - look up "Stirling Engine" for a good example of one.
There is a hidden power source.
close, but wrong! there is no temperature difference between the water and the air. and the power source is the heat of vaporization in combination with unsaturated ambient air. the vaporization enthalpy will cool the head down below ambient temperature and it will warm up again as soon as no more water evaporates. so the water in the glass has the same temperature as the ambient air. as soon as the air is saturated, the effect will stop.
i'm here because of tom scotts's video. looking forward to yours! :)
The device with the power source in the circular base is one of many examples of an "executive desk toy", a product fad that started in the 1980s. They're just intended to be interesting to look at; I've never heard of them being promoted as perpetual motion devices. Even when they were new on the market, everyone understood there was a battery in the base.
To be fair, SOME of these "perpetual motion machines" are just VERY efficient machines that will last a long time without losing very much internal energy. These are usually the more elaborate ones though. If you can get a machine to 99.9%+ efficiency, then it will last quite a while without a power source.
I liked the video, but the flashing colors really weren't nice. 0:46 2:07 3:37
Where's my epilepsy warning?
Just kidding I don't have epilepsy
alex skiles - It appears to be at a much slower speed than the (at least) 8Hz required to induce a seizure. Looks like it's around 3-4 Hz.
h-hm
alasyon as a guy with photosensitive epilepsy, if you're really tired or have some other reason you would be more susceptible to a seizure it can cause it at lower frequencies. It's just much harder to.
Hm, could it also b e that there is... a hidden energy source?
No.
Always look for the energy source. It might be temperature difference (either direct or caused by evaporative cooling), or it might just be a battery. ;)
Energy is matter nothing else
i find it very unscientific how people think the "laws of thermodynamics" are 100% undeniably true and should never be questioned. we created those laws so there may be some odd way it could be wrong. most likely not and all of the attempts at perpetual motion are just wastes of time....but i imagine if we got power outside of our universe, like if you got access to the console in a video game, you could "spawn" energy at your will. that would be outside of the laws of thermodynamics of course, but i still find it bad that people assume its 100% true, when almost nothing is 100% for us.
however i'm even more annoyed by all the perpetual motion nonsense people spew....so whatever.
It's not that the laws are 100% true and undeniable. It's that over hundreds of years they haven't been false even a single time, despite that it has been tried to break them. The only logical thing to do is ASSUME they are true until an observation that they are false happens.
The laws ain't 100% true. They are true until proven wrong, which nobody has been able to prove or even theorise with something doable (big warning here: something that we don't have the technology to make but work on paper could be enought to prove it wrong. But something that don't even work on paper, like monopolar magnet, will not). So until anybody can prove that the theory is wrong, then it is true.
thephantom1492 Quantum mechanics create perpetual movement. Quantum mechanics can break the laws of thermodynamics.
Rinoa Super-Genius The laws are always 100% true because the laws are observations (words, not equations) and based off one another. In your scenario where you get energy from another universe there's no breaking of thermodynamics. You're getting energy from somewhere and using it, energy in = energy out + waste.
, "But something that don't even work on paper, like monopolar magnet, will not"
I think that magnetic monopoles actually DO work on paper, i.e. they are theoretically possible, but never observed in the real world. According to Wikipedia: "notably the grand unified and superstring theories, which predict their existence"
en.wikipedia.org/wiki/Magnetic_monopole
Not gonna lie, that pendulum looks really cool
Is that for sale somewhere, it would look cool as a desk ornament
You can buy this everywhere. My brother used to have one when we were kids.
The intermission of flashing colors hurt my eyes :/
Remove them from their sockets. Problem solved. Thank you.
Ha lol fragile
I think the energy source of the first is not the water, but the heat of the room.
There is not always a hidden power source, sometimes they just start the thing with some speed and it has low enough friction so that when they say that it is getting faster you can't really tell if it's true.
Those type of perpetual motion machines stop after a while.
All 'perpetual motion machines' stop after a while. That's sort of the point.
Johnny, no, a machine that works for a long time is not perpetual motion. There's one in London featured in one of Tom's videos that's been going for over 100 years. The first law of thermodynamics doesn't specify a time limit, just that it must stop at some point, unless more energy is put into the system.
You're talking about the rolling ball clock, I believe. You know, the one that turned off when there was a city wide power outage in London.
Tom even says that in the video you're referencing. It was powered by electricity.
"thousands of perpetual motion toys that really work forever." Um... Did you even watch the video? There are zero perpetual motion machines that "work forever." Literally none. It is impossible. Why is that so difficult for some people to understand?
The hidden energy source for the rocking bird isn't the water, it is the temperature difference between the bird and the water.
more accurately, its the sun heating up the bird faster than it heats up the water
Tallywort *the air and the water , the water Gets colder from evaporating.
Thank you, that really bugged me.
AKA a Sterling engine.
Once the water has evaporated the bird will stop? If that's correct then isn't basically the water? Technical you guys are both correct ;-)
The way I think about this, is not “there’s always a hidden power source” (but this is true); I’ve always found it more intuitive to think “there’s ALAWAYS a source of resistance (not necessarily electrical... pls read on) that’s “decaying” the work the machine can do, slowly bringing it to a stop. Whether it’s the noise it make when operating (however quiet), or friction, generating friction; or electrical resistance in the wiring; there’s ALWAYS a decaying resistance which brings the machine slowly to a stop.
It kinda feels like there should be a photosensitive epilepsy warning on this.
Yeah. I was watching it full-screen and suddenly those loading screens popped up. Shit, it hurts my head than anything I've experienced.
Robert Williams - It appears to be at a much slower speed than the (at least) 8Hz required to induce a seizure. Looks like it's around 3-4 Hz.
alasyon good to know
Robert Williams - I was worried about it too, which is why I counted it. Though I agree with you - the colour change is sufficient to cause a headache!
There is one, not sure if it was there before, but it's hidden with a bunch of other text in the description.
Its actualy much Easier than you think, a complete basic Perpetual Motion machine is based on the flow of Time. By hooking a Tachyon Infused Semiconducting Quarz Cristal to the flow of Time itself via a realively simple crossconnection by 33.31 Jogus at the rate of 99 Ogol you can archive a 1° Turnrate per Minute alsongside the the line of the two points furthest of the Cristaline Stucture. Then connect the Cristal to some Gear so that the Rotary Axis of the Gear Aligns up perfectly with the Rotationary Axis of the Cristal. Then hang said Timegear into a kind of Stand and have it rotate its way. Hook up as many things you want to as the only Limit is the Structural Limitations of either Cristal and/or Connection Gear. It even works when Time Flows Backwards ... just have to avoid it suddenly being Deconstucted by Isolating itself from the Main Timestream without it loosing connection and with that becoming useless.
See? Childsplay!
I am already deeply sorry for Spoiling the Fun, exept figuring out what a Jogus and Ogol is ... honestly thats the hardest part. Also not sure if i wrote Tachyon correctly but you know what i mean once you see it.
Also saying something is Impossible means that its not. Common sense.
0:46 only other source of this music I've found is Tim Minchin's jazz-backed beat poem Storm. Awesome choice for transition!

When a magnet pushes another magnet does it lose energy? Eventually would the magnet run out of energy and not be able to push any more?
Domestos Bleach Yes
Well, not really, but there's another problem here. In order for new magnets to be constantly placed in front of the main one, for it to push them away, there's energy required. So, the whole system of you, the main magnet, and the magnets to be pushed away, there's still energy being used, by you placing the magnets there.
Yeah i don't get energy transfer some times. Like lifting up an object gives it higher gravitational potential energy.
Domestos Bleach You put in energy to get it that 'high' up.
No. Magnets don't lose energy.
What about the cat strapped to a buttered bread, eh? How will you debunk THAT?
Who feeds the cat? Hidden power source.

The cat may walk away while it gets dropped. Or if it does work, it will just fall down. And if you attach it to a pole to a generator, the cat will die.
Fact: Using the word “machine” with perpetual motion or energy, will give it a beginning and an end, making it finite. With this new and better understanding of perpetual devices, its meaning will need updating in defining it as finite. This way, these devices or machines will not violate the laws of thermodynamics, laws of nature, laws of physics, makes them patentable. ~Guadalupe Guerra
Why can't the guy on the left keep his head level straight?
Thermodynamics
Newton's first law of motion. :-)
Elijah Elliott-Ebanks there is a hidden power source
I had a University lecturer who 'knew someone' who thought they had proved the existence of magnetic monopoles. He called a press conference, and just before he went out to meet them, he spotted the error in his workings.....
It's sad that the videos showcasing these types of gadgets and making outrageous claims of perpetual motion get way more views than these type of videos. People hate being wrong, but a good scientist loves being wrong.
Yeah. In fact, science itself thrives on being proven wrong, because you learn much more from your failures than you do your successes. After all, as Thomas Edison said, paraphrased, I didn't fail 1000 times; I learned 1000 ways how not to succeed.
Lesson four: devices that use an absolutely tiny hidden power source to do something visually interesting are still cool
😂 true!
I love a good trick as much as anyone but as long as it’s presented as a trick or puzzle!
Can I debunk obese people who claim to not eat much using this as well?
John Hunter yep, thermodynamics speaks for itself. The body has his calories input and output and the balance of both get you fat or thin
LMAO, Kid (JPsk8core) got debunked.
LOL watch the video, it actually reinforce mi statement. Their metabolism slowed down, so they burned less of what they ate-> gain fat
that's what happened when you destroy your metabolism losing fat too fast, it happens to people who has just get thin, not for fat people
JPsk8core but can human metabolism slow down to the point where a normal intake of calories will make you obese?
I actually made a perpetual with no hidden power source. It had it's battery plainly visible outside in the very middle. So it wasn't hidden.
Just wait until i have my entropy inverter patented!
I reduce the entropy of open systems all the time! It's the closed systems that are trickier.
Around 4:05 when the fan started to spin my computer woke up from sleep mode and the fans spun up
But Shirely: The water, specifically the evaporating water is an energy SINK!, The energy SOURCE is the ambient air.
Yes, it's a heat engine and all heat engines work on temperature differences. In this instance acheiving that difference relies on the phase change of both the fluid inside the bird (ethanol?) and the water, and that relies on the air around it not being saturated and at a sufficiently high temperature.
There is a version of this which doesn't rely on a temperature difference though, it uses capillary action to draw water into a reservoir until the bird tips out of the water, then the water evaporates and it tips back in. It works very slowly though, many hours between cycles.
Tom’s eyes are STRIKING throughout this video
LoL at dude at the end with the fan. :)
I'm sensing a theme here... I wonder if any of the perpetual motion machines I've seen online have hidden power sources?
No, there aren't any perpetual motion "toys." Nothing will work without a power source.
".they just run around a bit..
but they do exist and they do perpetually"
That would require 100% efficiency. There is always a loss in efficiency in everything. So perpetual motion isn't possible.
Thank you for the seizures
"There's always a hidden power source" is really just a corollary to the much larger law "If it seems to good to be true, it is."
I eagerly await the not-quite-perpetual flock of perpetual motion fanatics to this video trying to defend their relig-- I mean, delusion. Actually, I think I had it right the first time.
It dependes how much energy you put into something.....The Energy you have put into this message for instance is at a set level.we'll call the units of measure Babbles
Lets see what returns you get, if it's more than you put in, then that is perpetual motion.
Stewart Savage Your joke, if it was one, kind of fell flat. Maybe you didn't give it enough energy?
You've just put in more Energy,so i must do the same to keep things even, so far we're at 2 babbles in and you have 2 returned
Hi. I am an external babble source.
haha nailed it..
if you put magnets on the drinking bird and a coil nearby in an appropriate position, could you not use the heating/cooling/motion cycle of the drinking bird to induce a current in the coil?
I think there's a power source.
It's probably hidden.
lol
You say the words impossible while also talking about Science? THE SINNNN
Lets talk definitions. While technically not "perpetual" if the power source was hidden well enough (lets say someone discovered the omni present dark energy, didnt tell anyone and used that) and the power source lasts millions of years, it would appear perpetual and relatively speaking wouldnt we be justified in calling it
Justified maybe, but still incorrect.
Derek McGowan , you said yourself that it's not a perpetual motion machine, so why would we be justified to call it that? A hidden power source is a hidden power source. And if you used up all of the dark matter then the machine stops working.. So, no. I would say we would not be justified to call it that.
Derek McGowan perpetual motion machine isn't really all that good of a name, if you have a machine working with no friction it will move on forever, but it isn't creating energy, a case like that wouldn't be violating the laws of physics. the term perpetual motion machine means a machine that produces energy which is a violation of the laws of thermodynamics which states that energy can't be created or destroyed, just converted from one form to another, also I just want to be clear, physicists aren't dogmatic about the laws of physics, if the laws of thermodynamics are shown to be wrong with sufficient evidence, that would be an amazing result, and i can assure you nobody would be more enthusiastic and curious then physicists, it just has yet to happen and most likely won't
itai alter im speaking of relativity. From our position/perspective (of unknowing of the source) it would appear to be perpetual and all experiments would report it as so. Soooo...
Also, yes a stated the concept but i group myself in with those who wouldn't know of its possible source
Also why is it that we dont define the laws of motion as perpetual motion? There is no energy source that i know of that propels the earth through space AND it appears to go on forever though, through the suns energy and incoming meteors and particles, it is gaining mass. So it appear tgat the same non energy that makes it moves increases enough to handle the increasing mass
I understand what is being said about the impossibility of perpetual motion and more specifically perpetual motion as a machine that does work. But are there any designs out there that could be called “persistent” (not perpetual) motion “devices” (not machines) that would move for very long periods of time, without any hidden power source? Any kind of design at all that could be set into motion, move without a power source, and not stop... perhaps for months or years, until critical parts wear out, like bearings or other friction points? Any design at all? I'm curious.
Flywheels
@@jasonpoole2093 Oh, okay, interesting. What kind of flywheel would that be; from what source? And how long do you figure it would go on its own?
the bird is fueled by the temperature difference between the room and the glas of water
Richard Pautz it works thanks to evaporation
+ytmoog Nope, because evaporation creates a difference in temperature.
not between the glass of water and the room, but the temperature differential between the base of the bird and its head, which in this case is caused by the evaporation of the water, eventually either all the water will evaporate or the humidity in the room will reach the point where evaporation for things at room temperature will stop, in either case the system will be in equilibrium and the motion will stop because that temperature differential will stop. if you like you can look up sterling engines which are engines that run of temperature diffirentials such as this bird
+ytmoog No. You got it backwards: I'm saying that evaporation creates a difference in temperature, not that difference in temperature creates evaporation.
***** yes
So you need an unlimited or renewable energy for perpetual motion. like energy that can time travel to make a loop?
good ol epilepsy transition cards
Why doesn't the magnets pushing a fan thing work?
I mean I get that it doesn't, but if the magnets repel and the fixed one can't move then shouldn't the ones on the fan be repelled, pushing the fan?
I think that's what he was implying when he mentioned "monopolar magnets".
even though i know it's a ton of lies, i quite like perpetual motion machines. I just think they're cool little desk toy trinket things. Even though i know there's a hidden power source i think it's cool for...no reason.
Perpetual Motion Machines
Step 1: There is always a hidden power source.
Step 2: Sell it to gullible people.
Step 3: Profit.
The water is NOT the energy source. Poor explanations lead to poor understandings of physics which in turn is why these kinds of misunderstandings happen. The energy source is the potential energy that is stored as heat in the room. This heat energy gives air the ability to dissolve a fix amount of water vapor in the air. This creates a vapor pressure differential, which is the force that actually transfers the water vapor away from the birds head.
People understand obvious forms of mechanical energy that they can see or detect. They often fail to understand the idea of potential energy which is much less tangible. Therefore, if you want people to think critically about overunity machines, you need to properly address the idea of potential energy and the non-obvious forms that it can sometimes take - such as differentials of heat or vapor distributions.
This.
Tim Harig The water may not be the energy source but it is the energy sink in this situation. The evaporation of the water removes energy from its surroundings and the water vapour escapes with more degrees of freedom storing the removed energy. The drinking bird would still work in a vacuum.
Anthony Khodanian The point is that saying "the water is the energy source" is a poor explanation that is not going to convince anybody against the idea of overunity machines. To explain it to them, you are going to have to relate it to something that they can visualize as having energy. They cannot put water in their car and drive it. They CAN see the heat in a room melt ice. Then you merely have to explain how differences in energies, forces, or pressures can are sources of potential energy that can be exploited to do work. When they understand that, they will be much less likely to confuse heat engines with overunity machines.
What about in a fusion reactor.
Tim Harig How is the water in this situation any different than, say, the gasoline in a car? People often think that the gas is the source of the energy, but its not. Its the sink in a chemical reaction, where the oxygen is the "source". Because only differences in energy are important, it is just as valid to call the sink or the source as the "source" of the energy when using common vernacular.
Just to prove my point with math, it takes 204 kJ/mol of energy to break an O-O bond, and 413 for a C-H bond. This then forms an O-C bond which releases 358, and O-H, releasing 476. This nets 217 kJ/mol in total. The oxygen in this scenario nets 213 units, and the C-H actually nets only 4. The energy is from oxygen, yet we call the source the gasoline. There's nothing wrong here.
2:40 why dont put a rotor generator on to the sides of the bearing then connect it to the battery
The work the rotor pulled out would be the same work the coil is putting in.
When you attach a generator to something, it slows down.

the color-changing background when doing transition is hurting my eyes
BlinkWhite They do in the description, not sure if that was there when you watched it though.
The guy whirling the fan cable is the MVP.
The drink bird still seems like a pretty good way to harness energy, no? Just get some water and an giant one of those things and you'll have some easy energy, though not perpetual
Vince Lombardi it's extremely inefficient though. the amount of energy it takes to make the bird bob is immense compared to any output and only just enough to make it bob otherwise you can easily stop it with your finger just resting on it. to keep a large one running (like a water pump to keep the head sponge moist) it'll end up costing more than the output. it's way easier to just set up wind turbines and solar panels
Thank you for that quick lesson, Dori C. A lot of people don't answer questions or reply to comments civilly on this platform.
How about the "atmos" clock? Do you consider it or not a "perpetual" machine?
Lesson one- there is always a hidden power source.
Lesson two- there is always a hidden power source.
Lesson three- there is always a hidden energy source.
What you should take from this- there is always a hidden power source.
Yeah NO SHIT
Is a perpetual motion machine plausible under ideal conditions? (In a vacuum with no friction between parts), or is 100% efficiency only possible with a heat engine
A few years back. I was working at a research and development company. And a person came in trying to sell us an invention that they had bought a stake in. It was a box. That whatever you plugged in only had a draw of 1/2 of the amperage of the device you plugged in. They told us we were not allowed to open the box, and they plugged in a hair dryer, which drue 15 amps And then when they plugged it into their box. The cord on their box which they plugged into the wall. Was split so you can measure the current. And it showed as 7 1/2. Which I immediately called out as a hoax. Inside their box they jumped the ground and neutral, and then taped the ground up with the hot wire resulting in the magnetic field canceling out half of the strength of the magnetic field in the hot wire. As the current was flowing in the opposite direction constantly.
Had this guy at school yelling at me about perpetual motion machines, and tried to disprove him use the first law of thermodynamics yet he was too stubborn to understand. "But the counter weights make the law not matter!"
I don't want a perpetual motion machine. I just want machines that operate for 100 years before running down. Just a healthy lifetime. Next generation can start their own.
Couldn't the swing motion from that second one be used to recharge the battery while also sending power elsewhere? ie one side have a wire to the battery and another to a proper generator?
Im confused if energy cant be made or destroyed then where does the energy go. When it run outs?
555 Droid so say you put electricity through a fan the electricity becomes Kinetic since the power is used to turn somethings so energy just transforms it doesn’t run out. Electric energy -> Kinetic energy in a fan
it doesn't "run out" instead it changes medium, to heat, light, sound, kinetic, electrostatic (yes I do know some are double im just simplfing here) and in doing that it gets spreadout. untill someone uses more energy to compress it again into a usefull package, like a battery or oil or wood.
Maybe I'm being semantic, but isn't the power source for the bird really the ambient heat?
Here is one way to possibly get closer to perpetual motion. Remove friction and wear. Yet when you remove those two things there are still many things that interfere like pressure
Soren Mortimer vacuum chamber to remove pressure?
Could you theoretically create a massive version of the bird and turn the kinetic energy into electricity? Or is it just impractical?
The perpetual lesson in perpetual motion is that there is a hidden power source.
would a magnet be considered a power source because they de-magnetize and can be re-magnetized using energy?
i still don't understand the fisrt machine, is it would work till the water evaporate or heat death of the universe ?
Yes, as long as it is in a normal temperature room, and the glass is kept full of water, it will work until the pivot wears out. But you really can't generate any useful work (energy) out of it. You could generate a TINY bit of electricity from it, but you could probably generate more from a thermoelectric pile with an evap cooled side.
what if something is efficient enough to be maintained by the coriolis effect?
Can it even be done?
This was fun and interesting. Very nice to see Tom Scott over here.
Is it possible that some perpetual motion machines could work in space (where they are not affected by air resistance or gravity)?
Yes, sort of - but really, no. In space an object could rotate "perpetually", but you would not be able to extract any energy from it; because that would make it slow down.
What about:
Super thin Superconductor, super magnet, and machine that moves up and down.
Will that provide enough energy to power itself and more?
