It would be so nice to go back in time to witness the development of stirling engines. Seeing how someone figured out the method of extracting work from air in a hot state and air in a "cold" state through an unique closed system. Fascinating, to say the least.
that means a lot when it comes from a teacher of your caliber - i have watched some of your lessons - just coz i think you are good teacher lol - cheers
You probably dont care at all but does any of you know a tool to log back into an Instagram account?? I somehow lost the account password. I would love any tips you can offer me!
you are an amazing teacher Robert and I'm really greatful for the display of knowledge and extra care in sharing this. Thanks. I've been doing quite a lot of research on Stirling engines and now want to focus more on FPSE as I have a project im working on for power generation. This has helped me a lot. Thanks
When i first saw your video about free piston type Stirling engine i immediately thought about application for it in a household. I did some research and found out that some GB company did exactly that, they took a free piston type Stirling engine and made a power/heater unit which uses natural gas to heat + generate electricity for your home. Now imagine if we take same type of Stirling engine and use heat from methane gas which would come from a bio digester in your backyard to heat water and make electricity! It would be basically free energy right there.
i agree - i am just getting the stuff together to demonstrate this as a generator - my idea was to attach a fresnel lense and sun it from solar but there are a load of heat sources that can be used and i like your suggestions
Great explanation, great video! I'm glad you talked about the regenerator, that was Robert Stirling's real stroke of genius. Technically it's not a _Stirling_ engine without it, only a heat engine, but trying to argue that most of the so-called Stirling engines on RUclips are really only heat engines would be like trying to bail out the tide.
Does the energy transfer also take place through exerting force onto a piston as well ? I mean will the air cool by exerting force onto the piston as well. The gas molecules transfer their force onto the piston and into mechanical energy which cools down the air molecules as well. If so how strong would this effect be ? I can insulate the colt side of a Stirling engine and it runs just fine so the air needs to be cooled off by an other effect as well.
Inside of the internal combustion engine you get an increase in temperature (because of the spark) and an increase in volume (because of the cylinder moving up) ... so does that mean that the pressure actually never changes? If the pressure inside of the internal combustion never changes what caused the motion in the first place? Maybe we can make machines that work on just combustion of vapors instead of using liquid gasoline. Awesome video, and Happy New Year!!
Is it possible to convert a compressed air driven vibratory shaker into a Stirling then. Bacause the air displacement happens to be the same but with only one moving piston and a moving valve arrangement 🤔 like a double stroke piston engine 🤔
Hi Robert, I have a request...would you please use darker markers that are not dried out? It is impossible to see your whiteboard drawings with the dry erase markers you have been using. Thank you
Your videos are entertaining and leave me hungry for more information. Especially about super capacitors. I plan on putting my money where my mouth is and buy more of your books.
1. Is there a danger with the Stirling engine that eventually the hot air in the cooling chamber will get so hot that it will stop working ? is there a way to make sure that can be eliminated or the water jacket is enough. 2. is there a formula available which allows one to change the dimension variable and or internal air pressure (say with bike pump ) to work out the output force or the effeciency so that one can tune it to get 2-5kw from sun's heat.
a very simple question which you may be able to answer for me since the advent of lithium storage batteries, Can the exhaust of a heavy diesel motor be the heat sourse of a Sterling motor with generated power use to drive accessories I.e compressor, air conditioning, power steering, supercharger etc
Hey Robert ! Glad to see you're back. Thought the holiday monster got you for a bit there. Happy new year. Thank you for this explanation of the Stirling cycle. It makes more sense. Now. BTW did you watch that vid on the Philips Stirling cycle rhombic engine? It doesn't make it clear like you do but it shows. Some cool stuff you can do with it.
Fantastic explaination! I see a lot of potential for the use of stirling engines in nanotechnology due to the simplicity of the principle. A minor caveat though, consider acquiring a microphone to clip to your collar. Regardless of how great a camera you have, distance from the device juxtapose to ambiance will always lower audio quality. You have a phenomenal brand, keep up the good work!
cheers mate - but you have to remember i am not a video production company and I tend to spend money on the experiments first - still i will think about what you say
Hi Robert, it was a great presentation. It was very helpful. I have a question: where can I buy this kind of canister to build the engine? Hope to read you soon.
Practically anywhere. Shop online for "stainless steel canister" or Target, Big Lot, Walmart etc. The exact size or shape is not all that important. An old tin can can work.
Hi Robert, great job on the explanation of this fascinating sterling engine type! I am interested in trying to use this device in conjunction with a aqua fesnel lens, a small electric generator and a battery in order to power some simple LED light fixtures. This is intended for outdoor camping/festival use. As I am a quite skilled within electronics the generation, charging and power conversion part is not a major problem. However I have a hard time getting around how to attach a generator to this devise - Would you have any ideas on how this may be done in a simple fashion?
Really good explanation and video! :-) It would be even better in a higher resolution so it is easier to se the effects shown and the drawings on the whiteboard ;-)
G'day Rob, I have to say this is the first understandable explanation of the Stirling engine I've seen to date. While I thought I understood this type I didn't know the half of it. Great job! BTW what was the story with the shiner?
Heck you were quick on this. I was just reading the paper on the Stirling engine that NASA tested in a van and a small truck. I never realized that these engines could do useful work. My knowledge of them was mostly as novelties and model engineering projects.
I am pretty good at answering my posts mate - low temp versions haev been used in solar to generate electricity - which is my own fascination with them
A little whimsey, but I have noticed that you are getting slightly darker in tone as your long term exposure to graphite continues. Eventually, as your visible surface area slowly gets enveloped in a tough cocoon of graphene, due to your experiments, it may be that eventually the camera will not be able to pick up your image as the loss of reflective power of your visage increases. This could prove embarrassing, as we log into your site and say incredulously "Who said that?!" as your dulcet tones appear to emanate from a smudge of sooty-ness near to where your head used to be!
lol - partly it's the graphite and partly it's because i just spent two months in Alice springs and it was sunny there - you should see the state of the bath after I get out lol

It's interesting how a lot of inventors were Scottish or came from Scottish background.

Your teaching methods are superb!
I have seen a dozen or more movies about the stirling engine but now i finally get it!
oh wow - cheers mate

lol - it would indeed - glad you liked it Dana
thanks for that, I now have working understanding of this machine, wecome back and a happy new year.
cheers mate and same to you

happy new year to you too mate - it's the increase in pressure that 'pushes' the cylinder and so increases the volume
It's actually Brighton Cycle, ye olde jet engine X)

lol - well that's good to know mate - especially the wanting to know more bit
Welcome back, good to see you mate

***** Hiya mate - i did a video on this - basically a magnet bolted inlinear generator fashion - it is on the engine playlist
any equation and its maximum and minimum value
Really good explanation and video! :-)
It would be even better in a higher resolution so it is easier to se the effects shown and the drawings on the whiteboard ;-)
yeah sorry about that mate - later vids are HD
:-)
well much appreciated anyway!
cheers mate
Këtu nuk kuptohet asgjë,përsëriteni materialin duke i skjaruar shumë qartë figurat dhe shkrimet që nuk lexohen.
Great video! Thank you.
I just did'n understand why did you put some magnets on your engine?
to help balance it - the magnets make it easy to add or subtract weight until the ratio is right
Oh ok! I hunderstand now. Thanks again, what you'r doing is great!
I'll try to make one
Cheers
G'day Rob, I have to say this is the first understandable explanation of the Stirling engine I've seen to date. While I thought I understood this type I didn't know the half of it. Great job! BTW what was the story with the shiner?
lol - cheers mate - it's not a shiner - it's dirt lol - we work a lot with carbons - i get pretty filthy

Seems that you worked up a bit of a tan in Oz
Your beer looked like it was going to get warm so I drunk it for you OK?
Bob from Oz.
we brits like our beer warm mate lol
How can we make best Sterling LTD engine that works on hand temperature , small size coin size
Much appreciated, thank you!
cheers mate
CAN YOU RE ENGINEER A TESLA TURBINE INTO A STERLING ENGINE .?
Will this engine run upside down?
solace1369 i suppose - but i didn't try it - i guess you could build one and do a video that would be interesting to everyone
