- This car uses a syringe to store potential energy in the atmosphere! Fun fact: there is roughly 250kg of atmosphere pushing down on your head, however it's also pushing from all directions, so the forces are balanced and you feel nothing!

To those who disagree that this is atmosphere powered, and instead human powered because I wind it up by hand, what about when I use the drill to wind it up? Is it now electrical powered? Or because that electrical power most likely came from a fossil fuel power station , is it now fossil fuel powered? Or because the energy in fossil fuels originally came from the sun, is it now solar powered? Do you also classify rubber band powered cars/planes as human powered? It's an endless circle of debate due to one simple law, the first law of thermodynamics, which states that energy cannot be created or destroyed. Thanks for watching!
Wow what a smart reply
Oh btw first reply!!
the winding up of the car can use any power, but as long as what makes it go is air it is air powered
Make it a submarine Tom! Put in whatever energy it takes to draw the vacuum, then drop it into a pool. Next rig it up to a propeller and I think you can figure out the rest. Technical caveat: if one pulls hard enough, the rubber plunger cap will pull off.
This has many applications for offshore energy generation. Think of the thousands of pounds of pressure which deep water exerts. This should be explored.
"Atmosphere powered" strongly implies that it derives its power from the atmosphere, not that it uses the atmosphere as a temporary energy storage. It basically implies something like the Atmos Clock. "Rubber band powered" doesn't imply the same thing even though it is worded identically because it's obvious that there is no way to extract energy from a rubber band without putting energy in yourself first. With the atmosphere you can (admittedly it's a tiny amount but still).
‘Sorry, boss I can’t come to work today....car won’t start....atmospheric pressure too low.
We need a real one
Legitimate reason
lol
That would only apply to a combustion engine. Low atmosphic change would charge the atmosphere car.
Combustion on the other hand does not favour low pressure. Electric would be fine too. And solar works on sunny and cloudy days double to half, at any pressure... only the combustion suffers, at low pressure.
Send me one: i'll test it out in my big vacuum chamber. I already know what's going to happen but it'd be a quick demonstration.
I'm pretty sure absolutely nothing would happen or, depending on the vacuum in the syringe, it might pop the plunger out would be interesting to see.
What I'd be really interested in seeing would be a vacuum chamber large enough to disprove the "theory" (and I use that word very loosely in this context) that rockets can't work in a vacuum.
Sure Cody! I can send one to your UPS box? Any maximum size constraints to fit your vacuum chamber?

Fun fact, you are about 80 grams heavier than a scale would measure you, due to the buoyant force of the air you displace.
Are you calling me fat?!? :D
Cameron Sours do we weigh less when the moon is overhead?
@@FunnygalsproductionsAnd do we weigh more when the moon is underneath? And what about the sun? Do I weigh less at midday in the tropics than at 6 o'clock or more at 12 midnight? Can Tom 3D print an engine that uses this differential? Good question ;)
@@Funnygalsproductions According to my calculations, a person of 100 kg would produce approximately 0.3 fewer grams of force (3 milli-newtons) with the moon overhead. In other words a normal breath (0.5 grams) is more than the force of the moon (but, that same breath would have almost no net effect on the scales, again due to the buoyant force).
An interesting fact for sure.
But, given that the majority of scales that are used to measure people with are accurate to within a single kilogram to at best 100 grams, that's well within the margin of measurement error. XD
Add in the errors introduced by wearing clothing which can add anything from 500 grams to 5+ kilograms, and unless you're willing to go naked, or weigh your clothes separately is a value that has to be estimated, and you can definitely assume that most attempts at weighing a human being have a margin for error of several kilograms.
Plus the weight of a human being can fluctuate quite quickly - going to the toilet for instance can cause the loss of 3-500 grams at least, and eating or drinking something...
Well, everything you eat doesn't just magically vanish, so that can add hundreds of grams to a kilogram or more in a short space of time.
For that matter, height is equally variable. - given the effects of gravity a person tends to be taller in the morning after getting up than in the evening, and the variation possible in a single day is in the order of 5 cm of height difference.
Which in effect means that giving your height accurate to a single centimetre is actually meaningless and only kind of an average. (for those playing along with Imperial units that means a person's height fluctuates by about 2 inches in any given day.)
OK, so the range in which it fluctuates is fairly stable, but it's still a pretty large amount of variability relative to how tall a person typically is...

"Tom Learns about Understeer"
Explain?
Tamahagane understeer is the term for when you try to turn a given amount but there is not enough grip and you just slide instead of turning
@@bobmcboblin can be solved by braking before turns yes
His front wheels also turned the same angle in a curve even though the outside wheel has to turn less far than the inner wheel so it starts to slip sideways
@@manitoba-op4jx ye but its next level when you manage to understeer and oversteer at the same time and I see that he was using some tiny Scandinavian flicks to turn that was pretty cheeky
its not just wheel spin. its drifting
Insert Tokyo Drift music XD
@@austin3013 ua-cam.com/video/XCiDuy4mrWU/v-deo.html
Deja vu
That chattering sounds like it's mostly just understeering to me... However cool it would be if it did actually drift 😅
Good luck recovering from that with your throttle literally stuck wide open.
Front wheels are not perfectly parallel, and with ruber they are fighting each other. He should put ruber only on one front wheel (for example right wheel if the turns are left), so the left wheel can slide a bit.
13:18 Tom turned into his "spirit animal" for a second there
Haha I noticed that too. Random cat paw lol.
haha i thought it was him
I love that you don't shy away from maths. This is how you learn something with practical use. Not videos that skim over the details for a nugget of information for the sake of not scaring off people who are averse to maths. Never change that about your channel.
8:53 - maybe using gears instead of strings on the 2 wheels could eliminate the increase in diameter.
or belts, belts a easier to implement
I'd build it out of legos, it'd be heavier and need more gear.. stages? But it would work
Had the same idea I had
That gave me so many ideas!! Very cool seeing that working so well!!
IVAN love what you do mate!
Atmosphere powered tank! Haha
@@localsms Thanks!!
@@TomStantonEngineering There's a challenge...
Guys Tom Stanton Ivan Miranda you are great inspiration,keep up the good work! :D
Your parallel steering geometry is causing the front tires to fight each other in the corners (inside tire follows a tighter radius curve so it needs to turn more) which is really slowing it down. That's why the rear started spinning out initially.
Look up "Ackerman steering geometry". This is a fundamental requirement of all vehicles with two front wheels/tires that turn independently (unlike the classic wagon where front tires are attached to a common axle).
petition to have him build another, more efficient and stream lined version
Sharpe guy, thank you.
@@Butterkin make the Bugatti of syringe cars, 16 cylinders
see at 6:00 and after. the front wheels have each their own axle.
but the hint for "Ackerman" is right. as a first approximation, the steering rod connection points should head towards the rear wheel rather than being rectangular to the wheel axle. the vehicle is relatively long so the deviation might not be that much - still it could make a noticeable difference.
the other thing that brought control loss in was definitely the hard and slippery grounds. that sees already best compensation with soft rubber gum wheels and extra weight.
en.wikipedia.org/wiki/Ackermann_steering_geometry
He should've gone with a rubber band on the outside front only.
Arguably, the string being thicker at the start is a good think because it reduces the gear ratio, making the car accelerate faster, but then later on when the car's going fast, the gear ratio is lower and the car can go overall faster. Like how in your real car, you would start accelerating in gear 1, not 5 because you have more acceleration, but you'd go down the motorway in gear 5, not 1 because you can go faster.
That's a fantastic demonstration of physics, engineering, and innovation! I'm glad I subscribed and can't wait to see more. :)
Next day on facebook: "Will future cars be powered by atmospheric energy?"
"Did a young man accidentally discover the future of transportation?"
"the energy problems are solved!"
Facebook in a nutshell.
There's already a vacuum energy meme. As in, virtual particles are always popping in and out of existence in the vacuum.
That's NOT atmospheric energy, it's simply a ay to store energy. The same energy YOU spend by creating a pressure differential...
Always look forward to your projects. Looking forward to whatever you get up to in the new year. Enjoy the hols!
Thanks! You too!
I waited for your videos every week this year!
Wonderful channel!
Thanks a lot Tom
I would recommend using a rubber band instead of string for the transfer from the middle wheel to the rear wheel

Hey Tom! Nice video, cool idea to use the pressure gradiant to power the car! I noticed one quirk though in your calculation for the total work the syringe would produce when allowing atmospheric pressure to push the piston back to it's original position. Originally, there is some air in the syringe (a small amount!). Then when you pull the piston as you say the pressure of that air volume decreases since as you say the volume increases. The absolute pressure of the air in the syringe is inversely proportional to the distance by which the piston is pulled. What produces the force on the piston is as you say the resultant pressure distributed over the area of the piston. That resultant pressure is the difference between the atmospheric pressure (nearly constant over the small time frame during which the piston contracts), and the pressure of the gas inside the syringe which varies with the position of the piston. Hence the total work is not produced by the force of atmospheric pressure alone, but the differential pressure and it varies with piston displacement. I am a big fan of your projects keep going :) your engine projects are very cool!!
Very glad i came across your channel. So often you see these channels show off cool technology, or ideas, without ever diving into the science of it. You take the time to make sure the principles behind the ideas are explained, every step of the away. Love that yearly recap you did there at the end. Looking forward to seeing how this channel will grow in 2019
As always, awesome video Tom. The compilation in the end was cool to watch

I think I’ve watched all your videos this year :) lots of cool projects & I’ve learnt a heap from your videos. Thanks... Highlights at end was cool :)
Great stuff Tom! Much more interesting to me than a “mouse trap” car, and one is less likely to get “nailed” by the mouse trap when it inadvertently slams shut”
Just had a thought about a possible “next level” experiment: would winding the string on a cone shaped drum improve the speed toward the end of the run?
If I had the time I would propose to run a spread-sheet calculation to study the parameters.
The idea would be to initially wrap the string around the large end of the conical drum and then work toward the small end as windings are added. It seems to me that this would increase the “average” moment arm length for the string, thus increasing the torque on the shaft as it unwinds.
A spread sheet would allow evaluating various changes in the geometry to maximize the average torque on the shaft as the “motor” unwinds. It might also uncover a major flaw in my thinking, but it wouldn’t be the first time that happened!
Thanks for all your interesting work!

Congrats on a great year of projects as well as Subscribers !!!! Glad I found your channel.. you are awesome !!!
They way you play is giving me great ideas on how to connect with students who did not get the same play that I did. Most of my play (learning through doing) was by tinkering with manufactured products that were either broken or discarded. Your play seems like a reboot of the world where less is know about manufacturing methods so as not to cloud one's creative abilities by realities. New tools, new ideas, but it's the same physics and the same results. Love it! Keep up the great play!

Ooh. From an engineering standpoint, this opens up a whole new can of worms. I will have to look into atmosphere energy storage.
Gorm Auslander the problem with atmospheric potentio-storage is that compared to other types of similar storage, it is impractical.
However, I can see potential if used in conjunction with atmospheric descent/ascension.
Take the kinetic electromagnetic suspension dynamo battery: can hold insane amounts of energy with minimal loss, but is not useable on anything that moves. The greatest advantages to atmospheric batteries would be extreme cheapness and simplicity.
You're a source of inspiration ! Good continuation from France !

Hey Tom,
great work again. However, I think you should have mentioned that the force is actually not constant but a function of distance, changing with changing pressure difference between the inside and the outside of the syringe.
Best, Joe
Thanks for the videos Tom, Merry Christmas
Good work Tom ! It is very ilustrative on Physics concepts. Merry Christmas and Happy New Year!
Hi Tom, nice video, ta. If you have a moment.... I'm befuddled by the first bit of physics
1. Force on piston equals atmospheric pressure times cross sectional area, yup.
2. Ergo force is independent of extension, yup.
3. Weight hanging from piston reaches equilibrium at a certain extension
Oh dear... it can't unless it requires less force to get it that far and more force to get it further, there would be no equilibrium point. So... amend point 1 to force equals F1 minus F2, where F1 is due to atmosphere (constant irrespective of extension) and F2 due to the residual air in the syringe when "fully closed" . Now as you pull the plunger F2 decreases until equilibrium is achieved. Fine. Now what's bothering me is that if i simply made a very snug fitting piston in a very long cylinder I would have a lab grade vacuum pump??
Hope your Christmas is in a nice atmosphere and free from pressure.
So I've been thinking and I'm only guessing based on theory. But if you were to follow Boyle’s Law, where P1V1 = P2V2 (Pressure1 x Volume1 = Pressure2 x Volume2), and V1 = 0, then P2V2 = 0, so P2 = 0? Does that make sense? Hahaha love those puns! I hope you have a great Christmas too!! (yeah I couldn't think of any puns)
@@TomStantonEngineering I just finished physics course of that thing on my junior year in finnish high school and it was lots of fun! I haven't thought about that force thing at all... What if you got that cylinder and made the piston divide it into two individual spaces, other having no air like in that test, and other having normal air pressure when piston is fully closed? That would give much more force, there would be vacuum pulling and high pressure pushing the piston.
There are several potential real world issues not covered by Tom's maths (so as to not confuse the bejebus out of people I suspect) and there are two issues which are easily understood but not easily calculated. 1 There is not a perfect vacuum in the syringe so even though the force does not change by much over the length of the draw it does change a little. 2 The reason for the issue with the vacuum is that for example water vapour sticks to the surface of pretty much anything at atmospheric pressure (Cody's lab discusses this to some extent) due to several things including van der waals forces. That tiny amount of water outgasses as the pressure drops meaning an equilibrium has to be reached as the water vapour pressure in effect increases.
@@gordonlawrence4749 This isn't like a vacuum pump that progressively tries to evacuate an already full chamber containing humid air - the syringe starts with all the air expelled, apart from a tiny bit left in the nozzle.
So, theoretically you could achieve a virtually perfect vacuum if the initial volume is 0.
@@TomStantonEngineering Well that's not really the whole picture; Boyle's law should hold for any extention along the way. Halfway through, p*V should also be 0, while none of both p nore V are 0. Ergo, problem.
I think this can't be modelled as a mere force-pressure problem, but more like a pneumatic spring via Hooke's law: in equilibrium, weight=k*extention. No idea what k would be, but hey, at least it doesn't return 0 :p
PS: You could calculate k via reverse engineering it: w=1.25kg*9.81N/kg=12.26N; d=0.045m. Therefore: k=w/d=272.5N/m, which might be plausible but might as well be of by miles.
2:53 interesting time save: pressure = energy (or work) / volume. Energy being *raw thermal energy* for a gas. So you could have multiplied the pressure of air by the volume of the vacuum you created in one step.
This is such an awesome channel. Great job Tom.
i love all your videos, ive watched almost every one and the compilation at the end showed me i missed a few ill have to see heh! im super happy every time to see what you come up with, and i cant wait to see what 2019 holds! happy new year!
Hi! This project interested me and I'm making it for my school project, but i need some meaning of this car for science or human. Do you have any idea?
I understand that you need a string to connect the syringe with the first pulley but could you not just use a belt to connect the wheel to the pulley?
Seconding this. The second string seems redundant when a belt can do that job.
You are one of the best UA-camr out there. Bravo ! And please continue !
Awesome work. Love it.
Seems to work really well. However, those front wheels create a lot of friction on the axle, causing a loss of energy. I would recommend fixing them tighter and with small bearings that you can salvage from old harddisks, those have incredibly smooth tiny bearings in them that spin with very low resistance. Because the wheels are wobbling from left to right they kind of 'pinch' the axle a bit causing more friction. If you add these bearings, the car will be a little bit heavier, but you can compensate by 3D-printing a clamping axle instead of using a metal nail to fix the front wheels and you can add some weight to the big wheel so it doesn't slip as much. One more thing, try to make the front wheels as thin as possible and use a tiny amount of hot glue (smear out with a piece of silicon rubber). This will give a friction surface too, and now you can make the surface superthin so it has less contact with the ground.
I think this was more of a "proof of concept".. The bearings you mentioned in harddisks was very useful to me though, I have plenty of old dead ones that I could salvage, cheers!
Marinus I had the same thoughts when I saw those wobbly front wheels. Using 💿 player bearings is brilliant! I’m sure it would work very well leaving the back wheel grip as the remaining issue. Thanks for sharing!
As long as as the rear wheel doesnt slip or spin in place , then no energy is lost.
@@Conservator. Hi Eduard, just make sure you use Harddisk bearings instead of CD drive bearings haha ;) Small difference. I use them for small hobby projects when the HDD has 4 pins. I normally only use the 4-pin HDD motors as a motor for a small project so the ones with 5 pins I take apart and salvage the bearings from.
@@RCinginSC Energy is never lost, it's just spread out more along the universe. But to stay within the scope of this project: the friction of the wheels is a big energy eater for the car. Friction with the ground, as well as the friction of the wheel and the axis.

Hey man, contratulations for this great channel, big hug from Nayarit, Mexico!
Make a syringe powered boat and put the syringe under water so that the force is greater , maybe ?
the force would be stronger but a very very little bit unless it is very deep in the water like 1km
interesting idea, to really take advantage of the hydrostastic pressure of water it would need to be more of a submarine, few inches of water just wont provide enough pressure.
@@Sikorsky66 i will say though that even a few inches of water on a surface the size of a door will make quite the force. you just need a larger piston (of course that will increase drag, especially in water.
Or submarine, the deeper in the water, the more force.
Even if it did have more force, wouldn't it be net neutral or even net negative due to the increased resistance and friction from the water?

@@redsquirrelftw they do work and can run until the mechanism breaks! The channel "British Museum" has a great little series on clocks. I think it was on one of those videos that a guy showed an atmospheric clock. Imagine inflating a balloon in a warm room. Overnight the temperature drops, the ballon shrinks. Next day it warms up and the balloon swells. Attach a lever and a precision ratchet to wind a light mainspring. Bingo! It uses air pressure variation to wind itself up. No good for centrally heated homes, but they were made in the old days. Amazing.

Great work, Tom! 🍄
Great video. You've earned my subscription.
Couldnt you use gears instead of rope and pulleys?
Yes, however there is a limit to how small a gear can be before the teeth can't handle the torque and this will therefore limit how small the larger gear could be. I think the smallest gear I've been able to 3D print with a decent tooth definition is about 18mm in diameter, which would mean I'd need a pulley 700mm in diameter for the first stage (instead of the current 150mm) and a rear wheel 750mm in diameter (instead of current 170mm). So using the string/pulley method helps keep everything more compact and simple.
@@TomStantonEngineering I guess that same problem also applies to a planetary gearbox?
You could skip the small gear by having a toothed shaft coming out the back of the syringe instead
Tom Stanton Have you tried a worm wheel setup, given that the syringe provides plenty of torque to overcome the friction of a worm wheel and pinion.
Blubberbub Yes but x100 ;-)

I'm not arguing Your case, I'm just curious as to why You call it "ghost-Banning" as the "ghost"-prefix usually means that someone is "freezing/disabling/nerfing" an account without informing the account "owner".
But I thought that Patreon literally informed the account holders in question that they wouldn't allow them to use their services anymore ? Have I misunderstood this ?

I take your hmm and raise you another hmm. It's actually solar powered, via the food that Tom ate to power his muscles in winding it up. The rest is just temporary energy storage, using the tugging of gravity on all them bits of air out there to push the piston back in.
Ray Kent OO yes. I didn’t think of that😄
@@raykent3211 Have a look at my comments under Tom's first comment. I talk a lot about this.
@@lio1234234 ta for the response Elliott, I agree with what you said. I think that "atmosphere powered" is a reasonable name for this. My comment was playful. I'm sure you don't need telling that there are other contexts where it is important to trace through a bit. Electric cars are advertised as zero emissions irrespective of whether the owner recharges the batteries from hydro or coal fired. In that case the difference between the two ways that solar energy is captured and released is mightily significant. So I don't quite agree with tom saying, in effect, that it's useless circular argument. Though in the context of this toy car, yeah, it's insignificant.
@@raykent3211 of course. I knew that what you said was playful. I was just explaining my thoughts to people.

Very interesting and good physical explanation
A German automotive engineer here, there is a lot wrong with this:
It makes much more sense to contract the syringe because the maximum pressure you have otherwise is just the atmospheric pressure. Its like hydraulics first lecture. Furthermore, the power that can be used to drive is variable over the stroke and tends towards 0 when the internal pressure is equal to atmospheric pressure, so in order to get your Power integrate F=(p0-p(s))*V(s) to stroke s. Just make a free body sketch from the syringe. Please dont spread false knowledge.
Just call the video "making a pneumatic battery from a syringe (in the wrong way)"
British aerospace engineer here: I explained why I chose to expand the syringe rather than contract it. Expanding it applies a 'more constant' force (obviously not constant due to it not being a perfect vacuum, as explained when I hung the weight from it) on the system which is easier to manage. The calculations were carried out in high school detail to help with convey the theory, therefore it was assumed there was a perfect vacuum. Using P1V1 = P2V2... if P1 = 0 --> P2 = 0, therefore theoretically, if there is a perfect vacuum, the force is constant.

@@TomStantonEngineering P1V1 = P2V2 is an isothermic assumption, which is alright (id prefer isentropic because the temperature decreases when expanding but ok) but as you know from thermodynamics using the ideal gas law and integrating:
The volume change work released in your process would be W=-m*Ri*T*ln(V2/V1), and not just W=p_atm*A*s
It´s just wrong mate
Let me calculate an example for you:
Assumptions:
T=293K, Ri_air=287J/kg*K, Density at Point 2=1,3kg/m^3 -> m_air=1,3*10^-6kg
Before) V1=20ml=2*10^-5m^3, p1=1bar=10^5(relative to the outside)
After) V2=1ml, p2=0bar, absolute pressure is then 1bar
We get W = 0,327J
You on the other hand assumed that we can mechanically use the entirety of the hydraulic energy stored, which is W = p_atm*V1 = 2J,
which is a completely wrong assumption because its actually W = integral of (p_atm-p_system(s))*V(s). If you remember thermodynamics: this is the volume change work, W=-integral of p*dV
So congratulations, in this case you would be off by 512%
@@ch98hb I didnt follow your calculation but isnt toms assumption based on the atmosphere volume being almost infinitely huge while the syringe volume is a tiny tiny fraction of it so the force coming from the atmosphere is constant because atmospheric pressure will change by an amount so small its even impossible to measure... It makes total sense to me what he did. Or did I completely miss your point? Seems like you ignored the fact that he pulled a vacuum instead of pressurizing it. So even if made a syringe 100 times longer the atmospheric pressure and therefore the force would be the same as with the small syringe over the entire length of the syringe
I got chills by watching that dry marker write. ouch.
Cool videos and concept.
You are the BEST youtuber I've ever come across. I know there are many others whom I haven't come across, but ur the best so far I've seen on UA-cam.
Merry CHRISTMAS and Wish you a Very HAPPY NEW YEAR..... 🤗🤗🤗🤗🤗🙌🙌🙌
