  • A Demonstration of a low temperature differential Stirling engine and a
    3D animated illustration of how it works.
    This has been updated from the last Stirling engine video with countless improvements including a demo of a real Stirling engine, voice over dialog, reworked animation and rendering and much more.
    The animation shows the simple concepts in detail and how they add up to make a working Stirling engine.
    In the demo the Stirling engine is shown running on a cup of hot water and on a block of ice running in reverse.
    It has been so fun to see everyone's comments, views and so on since I posted this video. As I mentioned in a comment, for me this was more about the Blender 3D animation software than it was about Stirling engines because it took so much time and effort to animate it. Stirling engines have also been a hobby of mine. I chose the Stirling engine topic because that seemed like something I could offer a little bit of information that non-engineers like myself could understand, and something that wasn't already extensively covered online.
    I am not a professional Blender animator so this took months of effort in my spare time watching Blender tutorials, modeling, story boarding, animating, rendering, video editing, closed captioning, finding music, etc. The final cut of the animation took about 3 weeks straight of 24 hour rendering. One reason I don't have more videos is because the couple of videos I have took so much work that I got kind of burned out. But in the end I've sure enjoyed these projects and all of your comments, etc. Thanks for watching!

    Great Video! Finally really made me understand that the displacer piston is not affected by pressure differentials, but rather is moved by the power piston. All the other animations I've ever seen made me think the displacer piston was pushed on the bottom by expanding hot air while the top was pulled up by the vacuum of condensing air. I finally understand that only the power piston is effected, because it has one side to atmospheric pressure, and the displacer piston is just there to move around the gas so the gas is expanding or condensing overall... whew! So weird that I never really understood that before... now I can look at a stirling engine without my head hurting. Thank you!

    You don't need the dis-placer, just drill some holes on the top of the cylinder to let cool air in and hot air out.

  • @pepsiatlas5452

    @merciadragon9425 10 лет назад

    Going back many years when I was living in Western Australia I was working at the siding called Hines Hill & in the bar of the hotel they had a Stirling engine fan. The driving force was a small flame I think produced by kerosene. If the only one I've ever seen and it is always add me fascinated and it is memories of that that brought me to this page. Thank you very much for the explanation.

  • @onelucian
    @onelucian 29 дней назад

    Had to watch it 2 times. Now I get it, and hope this helps someone: the displacer is NOT moved by the air at all, but by the piston.
    It's so simple now, wish you mentioned that. I was getting stuck at "how in the hell does the air move the displacer so it can move the piston and so on?" 😂

    The Swedish Navy recently deployed a submarine with a Sterling engine! It burns diesel fuel for heat and it is extremely efficient and here's the best part: it is virtually SILENT compared to more common nuclear and diesel-electric types! This makes it extremely stealthy and thus one of the best submarines on earth. The US Navy "lost" an Aircraft Carrier to one of these Swedish Sterling engine subs in war games and so the US has leased one of the amazing boats, to study it's amazing properties!

      @ziiofswe 4 года назад

      The HMS (HSwMS) Gotland and its sibling Uppland were actually made back in 1995... but they were upgraded somewhat recently with improved Stirling engines. (Amongst other things.)
      Also those war games + lease were back in 2005-2007.

    @stevemurray2017 2 года назад +1

    Very, very good!!! And almost perfect. Since you have such great animation, I would add arrows or some other way of showing the air expanding below the displacer and moving into the power piston and then the cooler air above the displacer contracting and pulling down the power piston. Thank you very much for a great explanation!!!!

    There's a science facility in Iceland I've seen and a friend worked in for 2 months. They're connected to the grid, but most of the time by he put energy back into it. Because Iceland is so far north it's temperate in the summer because of the gulf stream (like here in Ireland) but cold in the winter (a lot more than Ireland). They use the geothermal energy to heat the bottom of what he was told were 12 engines that power 2 alternators (6 engines each) between these and their emergency battery back they run practically fossil fuel free 12 months a year. Even their heating system is heated with a coil like an emersion. Granted it's slower than a gas or oil burner, burn its more reliable (according to them) and can simply be left on at a certain current setting depending on what time of the year. I really think it's a highly simple machine that can be tuned to take advantage of an specific temperature differential. Their engines looked more like the fire field ones you can get or see on RUclips, rather than Rhian low differential one. This permits more revs (as far as I'm told). However as much as I'd like to know... I dont know the exact physics behind tuning them. Either way, not even my love for rotary engines can beat my fascination of these! I'd love to see them used in computer server rooms one plate and the flywheel in the room, the other plate as part of the outer wall of the building. Imagine the energy savings! Grasshopper tea your not getting energy for free, it's measly recycling a large portion of lost heat energy from the current in the server electronics. Or like in Iceland. Use geothermal energy in cold climates, or cool underground temperatures in warm climates (that may not be as efficient or successful though). Hey stick them in a car or god bless you if someone reads this and stick 's one in a Bike..... (But efficiency may be a problem on that part...)
    Either way... Best engine i by he world olid you asked me...

    Thanks! I'm not sure about all types of Stirling engines, but this type won't start on its own. You have to spin the flywheel before it will start. It of course also needs heat energy in the form of a temperature difference between the top and bottom before it will run.

    @mstreeter11  11 лет назад

    I'm not an expert beyond the basics, but sources I've read seem to agree that Stirling engines have the potential to be very efficient. I believe this is at least in part because the heat that is put into it is not sent out an exhaust pipe like it is with a gasoline engine for example.
