How Automobiles Work

This is a Stirling engine a miniature version
of the real thing to be specific and I’m not just showing you this engine to show you this
engine I actually have a plan in mind if you’ve seen any of the previous episodes you know I like that I like pushing things to their limit and this is going to be no different I want
to see what the maximum rpm is that I can get out of this engine with the intention
of blowing it up but before I do that I want to show you how this engine runs the way it
comes if you buy it and then move into the high RPM runs right after that as you can see this engine is pretty cool
and functions perfectly it runs it’s a real engine in my opinion this is an awesome little
engine for the price because it’s literally a miniature version of the real thing I think
a lot of people will enjoy this engines so I put a link in the description below if you
want to buy one and I get credit for every single one that you buy so by as many as you
want and the way these Stirling engines work is you have a hot piston here a heat exchanger
and a cold piston here it takes the heat that is created by the flame at this hot cylinder
and converts it into rotational ForceI did a little video while I run this engine non-stop
for 3 hours straight now that you see how this engine runs normally and we know it can
run for at least 3 hours I want to see not how long it will run but how fast It can run
and the way I’m going to do that is by turning up the heat I’m going to heat it up with the
MAPP gas as hot as I can get it and see how fast I can get this thing to go right away
it started moving here we go maximum rpm oh yeah geez practically melting the glass and
still nothing’s happening all right well that that answers that question looks like I got
about 4000 RPM out of this engine but who’s number which doesn’t sound like a huge number
but if you think about the fact that most Stirling engines run between 400 and 600 RPM
with certain designs getting up to 1,200 RPM 4000 starts sounding pretty impressive this
is kind of unfortunate I mean we have some damage but not the amount of damage I expected
the whole engine is pretty hot this whole thing is hot but the weird thing is that the
cylinder isn’t damaged but the Piston has melted if you look inside their the Piston
is melted but the cylinder is undamaged I’m telling you this really surpassed my expectations
I think it’s definitely worth the price that they’re selling this thing for because if
it took that I mean man definitely worth its weight in gold that’s a little bit exaggerated
I can’t believe the Piston inside Melted but the cylinder is still intact it’s the strangest
thing I’m not sure I’m going to actually try to take this apart and see how this thing
oh look at that it’s like loose what the heck oh goes the weasel look at that there’s little
o-rings in there oh look at thats are damaged oh man look at that piston looks like a little
icicle I think this would have stood running a little bit longer but it definitely melted
the Piston inside of there I want to open this up and see if we can somehow just take
this apart crazy look at that this is just like a steel piston inside of a piece of glass
that fits inside of another glass tube which is the cylinder that’s crazy it fits so tight
in there wow how they get that to such a fine tolerance is beyond so now I’m going to take
this little retaining ring off of the connecting rod and I think this whole piston is going
to slide right out of that cylinder oh yeah it comes right off that’s kind of cool you
can take this whole thing apart with no tools oh there is goes I can just slide this whole
piston right outoh that’s pretty cool this is super simple look at that thing it’s just
this piston this steel piston inside with a connecting rod it’s attached to this glass
piston it looks like you can just oh their you go and this piston slides inside it all
comes apart with no tools that’s pretty cool so I guess all I need is this glass piston
right here and I’ll be back in business so maybe I should try that and try this one more
time let’s see whats inside there it’s just like a little glass tube such a simple engine
it’s just a hole in the heat sink and a little vent hole here 2 Pistons 2 connecting rods
and a flywheel and a counterweight I wonder why this engine never made it that was pretty
uneventful I didn’t even get to do any of my load test or my second idea because the
engine didn’t make it through the first idea but I told myself if something is intended
to be a full episode And it doesn’t work out I’m still going to post it because sometimes
things just happen but they’re still cool to see thanks for watching don’t forget to
subscribe check out the notification Bell because there are some options there and that’s
about it see you soon

  2. Love this engine, just bought one for my 9 yer old for Christmas.
    Maybe it never took off commercially because of the lack of torque!!
    Good Vid 🙂

  3. I, and a couple other folks, have wondered about power output. It's real easy to get some results with the built-in dyno. Just wire up that belt-drive "motor" with a proper-sized resistor and measure the current. Volts, Amps, Watts!…use an electric model plane Wattmeter that reads out all three. One horsepower equals 745 Watts…use Watts for bigger-looking numbers!
    One could even set up another brushed motor running off that onboard generator with a fan to move air through an air/water intercooler that would pull heat off the "cold side" of the motor and make for a higher temperature differential. Make sure that the water in the intercooler thermo-siphons like a Ford Model T cooling system so no pump is needed…put the intercooler higher than the heat source with no dips in the lines. Use model plane silicone fuel line for water lines to intercooler.
    I like the liquid Nitrogen idea also.
    You could do "dyno runs" stock, stock with intercooling, and stock with nitrogen cooling. THEN you could do runs stock with MAPP gas. Mapp gas with intercooling, and finally MAPP gas with Nitrogen cooling. Maybe reverse the order of the MAPP gas runs so that the damage to hot side happens on the last run. (stock) For stock runs, just pinch off water flow to intercooler.
    Compare Wattage on all runs for a full test set!

  4. You can get more power and RPM out of it by using a can of freezer spray on the other cylinder and piston at the same time as using the blow torch on the hot cylinder and piston. The bigger the temperature difference between the two is the key. Thats assuming the freezer spray is not flamable. Love the videos

  5. Nothing uneventful about this bro! Most scientific experiments that fail are the most important and interesting cause that's when you learn the most! Keep up the good work!

  6. Maybe you can get pyrex tubes/cylinders and try again but also cooling the cool side, maybe putting a container with water/ice or dry ice

  7. for the heat, can you put a magnifying glass to harness the sun, then on the other end generate electricity. Just for fun.

  8. Im curious if this engine would run faster with a piston that had more dome, so that in theory compression would be higher? Also the belt attached to the electric motor is definitely slowing it down with parasitic drag

  9. I have a USB port wired up to mine. Charge my cell phone off it when the power goes out 😁
    If replace the air in the cylinders with helium(I think) it will spin faster aswell

  10. You should try to make or get a metal piston and cylinder so it won’t melt and you can hit it with an icy acetylene torch!

  11. As a professional Oxygen Not Included player. I highly suggest a massive heatsink fluid? gas? solid? at the cold end, so it dissipates fast but never gets dangerously cool.

  12. Zero torque is why the engine never succeeded, for the same heat input a steam engine could do roughly 27 times the output.

  13. That is so cool Not a bad price either! Hey Are you still going to do a Electrical Fire demonstration? I think you should make a 8ftx 4ft wall and short the wiring some how or so Electrical over load to demonstrate what happens inside the wall when wires get super over heated/Overload.

  14. I wonder if the cylinder is made of borosilicate and the piston is regular lime glass.
    Also, water cool that cylinder on the cold side! Water cooling will improve the differential without the problems of liquid nitrogen. You can always run a dry ice/acetone coolant.

  15. Lubricant minimises friction . Braking system on cars converts kinetic energy into heat . Interesting vid nonetheless 👍

  16. I do not really like Stirling videos like this, where the speaker do not know too much about that hot air engine basically, but it was a great presentation for the limit of this engine. This alpha displacered type engine is a nicely machined one, and fast. You could increase the speed easily with some wet cooling on the machined aluminium part, but if you can fix the stand first that gives you a much higher speed basically without more heat or cooling because you stoped the negative resonances. Also you should take off that rubber O ring from the generator, that has a pretty high friction. Anyway, the video is cool, good job man! Greetings from Hungary! BLADE

  17. I know it'll drop the RPMs so it won't be as clickbait impressive, but could you try running the thing with a load (if it's still alive lol) to see how much extra power you can get out of it with the blowtorch vs the alcohol lamp? Just hook up a resistor and multimeter to the motor so it's not free spinning…

  18. With the extremely rapid reciprocation of the piston, and the additional friction heat that likely created, I'm not at all surprised that it deformed. I am still surprised that the cylinder didn't, however… Regardless, I found this educational, and highly entertaining.

  19. For the most part, Sterling engines never made it because they don't make enough torque. I have heard of one country that has put them to use in a submarine, I believe it is Sweden.

  20. I'm guessing the outer cylinder wall is made of quartz glass (same as 500w work light bulbs) which can withstand much higher temperatures

  21. Gadolinium halbach arrays with strong earth magnet's for a cold gas stirling cycle engine. Pistons in a circular configuration with a gadolinium magnetic wobble plate that drive's a fan. Gadolinium halbach arrays generating low temperatures able to turn Argon gas into a liquid that circulates through the piston heads through condensing coil. New air conditioning system. A central air conditioning electrical power generation system?

  22. I thought the slow motion of the car at the end was awesome too. You might be onto something there. I don't think I've ever seen car damage in slow motion.

  23. Dude! I said it last time, this little thing is super cool and appears to be very well made! Can't wait to see what kind of future abuse you put this poor little thing through! LOL!

  24. Piston melted earlyer cause. You Stupid heated the iron body arround the piston till red
    (so heating the full engine too)

    Also lubrication was not aprpropied to the heating made by friction at that speed

    Test supoused to increase heat slowly.
    My opinion the machin could go over. The 5000 r.p.m.

    Next time pay to somebody else to point the torch correctly cos
    Yo go nuts when talking
    Make the engine producer to look much better dude.

  25. The Stirling engine has Problems with the Power control and it is expensiv as a Combustion engine, with the same power.

  26. That's a fascinating engine! I gotta get me one. I am curious, just how much power you can get out of it, by loading that little dynamo on it. I think it's just a carbon brush motor, so I suspect, it puts out direct current. As much as I would focus on heating the chamber, I would also focus on providing a small amount of airflow over the heatsink, to help create a higher temperature differential, to make the engine more efficient, as well as more powerful.
    I would even try heating it with a resistance electric heating element, and compare that wattage, with the wattage I could get out of the dynamo at optimum load, and measure the true thermal efficiency of the engine.(~4%?) I don't know what the lubrication requirements are, if any.

  27. These engines operate based on an optimum temperature difference that is directly linked to the ratio (by volume) hot/cold end. Adding more heat will not make it continue to go faster and faster. In the same way adding more coffee to a full cup will not make the cup bigger!

  28. The reason Stirling engines are not in our cars today is because they invented the internal combustion engine. Which had faster startup and better throttle response. NASA actually did make one that fixed these problems, but the cost per engine was very high because of the use of exotic materials. On the other hand some military submarines use these engines , and they are said to be much quieter than a nuclear powered. sub. Only down side is they would need more frequent refueling compared to the nuclear fuels rods lasting many years. But would be much safer with out all the radiation.

  29. Instead of just overheating the bulb end you need to cool the other piston with some compressed air or air duster or circuit freeze. Those engines run off of a temperature difference between the hot bulb and the cold piston. So making the difference bigger is better than overheating the whole engine. Keep up the destruction!

  30. When the nagasaki bois in the riced out civic you racing spools up so you tell your friend to light up blow torch underneath the glove box because they need the full gapplebees menu not just the gapitizer
