❤ (UPDATE: Deadline extended until May 31!) Dear Rob, Thank you for sharing my contest and inviting your audience to it. I hope some of these people start building their own units because this is an incredibly underrated part of heat engines. I will probably expand the entry time interval soon, because it seems to be too short. I am very grateful for your contribution and I congratulate you on the new presentation space and your workshop! BLADE
Both of you are brilliant for sharing your knowledge and actually teaching others how to etc Bless Both Of You for CARING and actually SHARING what you know with others old n young alike 👍
You two are awesome, I love both your channels. The here proposed solution could be used by many many people for generate some electricity for their ligths and such. Many people choose TEG elements instead of the Stirling engine because it seems more obvious and simple, as it is solid state. This is a great example of how a Stirling solution can be just as cheap and easy.
The ultimate Stirling engine was designed and tested by NASA, there's a very interesting video on the program in which several iterations and designs were tested in real world conditions in various trucks and cars. I did a deep dive on it after watching the video and it's a wonder they disappeared the amazing tech from the public.
saw your old video about the stirling engine because i was doing some research on it so i can make one. im glad your doing a new one on it. i also have an on going project on wind turbine and found that we are at the mercy of nature and geography. i think sterling is the way to go as it is power on demand. nice video/channel mate!
I really love this concept, it´s so simple cheap and yet effective. The only improvement I would like to mention is, the lowest temp on the cold end is about 100°C due to the boiling water. It is important to get the highest temp gradient possible, especially on the cold side. Thus a better cooling solution would be needed. Something like a condenser, a water cooling AIO from a PC or something like that.
Yep, but they are not active now. The company changed a lot, the name and the CEO is different actually. They have no products yet we can buy. But the company is working a lot in the background. They want to show something new in 2023-2024. I'm so excited about that.
I would love to see a low cost sterling engine put into production, something that costs about the same as a lawn mower engine and is about the same size. I wanted to make a 6 cylinder alpha sterling engine out of metal using bronze electroplating because bronze can be very low friction and retains heat well. Perhaps using a steel tube for the cylinder, cast aluminum pistons, a Hemispheric head for even expansion as a prototype. I'm going to try and work on it, but if anyone else can build that concept, awesome! There are a lot of people in the rural United States that have wood boilers, solar thermal is also not too expensive, this would be a huge way to get self-sufficient electrical power in particular to everyone, but in particular places where the grid can be a little more spotty and where power outages can last for a week or more.
I love philips' mp3002ca motor. Maybe one day I'll get my hands on a clean one. I love following you. You're very good at what you do. Congratulations.
A thing I've been wondering about, is if you could use the principles a heat pump to help a stirling run? As a heat pump has a coefficient of efficiency greater than 1, it seems like you could use one to take heat from the cold side, and pump it back to the hot side to maintain a better temperature difference and greatly improve the efficiency of the engine. It seems like it might be worth the energetic cost of running the compressor to recycle that heat back into the hot side of the engine.
Great fun do you think one of your water lenses and the sun would run one of these if only I could find that damn round tuit I would be away. Many thanks
Edit: Boilers, as well as Sterling engines, are both "external combustion" engines. "They put the flame on the outside" is not what made the difference. The difference was the working fluid. Obviously, the working fluid in steam engines, is steam... more specifically, water vapor (in more efficient variants). Water can be an extremely volatile working fluid at its most efficient extremes (vapor/ice), as can exceed the design limits of the machine. The most advanced form NASA/DOE sterling engines utilized nitrogen gas in hermetically sealed circuits... making it much more friendly at its limits, as nitrogen can be easily contained in its near-critical/non-critical transient states.
Ah, the memories. Looking at those cars I was wondering if there were a way to do a solar Stirling car. Put the hot end on top in a glass box, like a solar oven in the hood (I think you call that the bonnet) and then air cool the bottom side as you drive, maybe using a few solar cells to run a fan when you're parked or in traffic.
One of the Stirling Engine Techs I am interested in is the Flat Plate Stirling Engines, which are being designed to compete head-to-head with Solar Cells.
I was thinking about your last video, where Several of us confused your use of the word Torch. I was thinking... Could you make a Electrolysis Hydrogen/Oxygen generator that runs on blowing into a tube, which generates enough hydrogen and oxygen to light a small hydrogen torch?
@@ThinkingandTinkering yeah being from America I thought we were gonna play with fire again 😂 then I remembered y'all call Flashlights torches for some reason 😅
I've always thought of a sand battery with a sterling engine so use all of the salvage generators you've done to heat a sand battery then use the sterling to make the power when there is no wind sun or rain
Could you technically use a heated coil by running electricity through it as heat for the air to move so there's something to move the sterling engine?
@@fireballloadout Absolutely, but it depends on how much current you apply to the coil. A fun video on youtube to search for is something along the lines of "boiling ice with induction heating". Theorically, people should really be looking heavily into steam hybrid systems, because you can run steam engines/turbines/rotors now without a boiler.
Hi I have made a number of Stirling engines and love them but I had the chance to buy a book in the late 1980s about a multi cylinder squish plate sterling engine that was & as far as I know is used I most submarines ( advertised in the irte or engineering council magazine) & I deeply regret not buying it. It was similar to a hydraulic hydrostat motor & it has fascinated me ever since.
What is the possibility that you could perform a specific experiment? Sterling engine powering a small A/C compressor and the low pressure and high pressure line providing the heat for the sterling cycle.
You don’t need a compressor. Use one Stirling engine to drive a second one and it will produce heat and cold as needed. Stirling refrigeration is incredibly efficient.
safest and simplest engine is the steam putt putt engine no moving parts and nothing to wear out could be used to turn a vertical spindle in a pool of water you should look at this I have built a full size one to power a 12ft dinghy but the rivers to high to test it at the moment I wonder if it will work
look at the ones by darrel foster just a tank and pipes try it with just a coil of 4mm copper pipe and it still works. blade did somthing with a diaphram putt putt and a dolphin tail that was quite interesting as well.
The USA Air Force had a working Stirling engine before the doe asked but it has never been allowed to be put into production, probably because of the Invention Secrecy Act.
Might it be possible to make a very low temperature stirling engine that would run off body heat by changing the type of gas on the inside of it? And by using a thermal Cline to trap the heat and make one that would run off a candle or a farm animal like a chicken or rabbit their body temperatures runaround 101 . If you were to use a larger surface to pick up the heat and turn that into a thermal Cline to capture the heat and like a battery a heat battery heat would stay put because it rises up. It would be interesting to try to make one run off your body heat while you're sleeping. Charging up your systems. The only weak point is that rubber balloon. I've seen them use ferrofluid that balloon needs to find a second option. I don't think it'll stand the test of time.
I'm designing a Sterling-type engine that runs at very low temperature differential, high internal volume and low speed. Has anyone done anything like this before?
yes mate I read a research paper where they ran an LTD at half a degree temperature difference - I don't remember the paper but it turned up quickly in a google scholar search
I wonder how hard it would be to 3d print some of the more difficult parts of an alpha Stirling Engine. Pistons, head, linkage. Using standard PVC for the sides. This wouldn't be my bronze electroplated Stirling Engine 😂, but it could be an affordable Stirling engine.
@@ThinkingandTinkering I truly appreciate that, thank you! I think a lot of the files available are either the beta type sterling engines and/or use syringes has a piston and cylinder. I took a computer rated manufacturing class in high school 15 years ago, I really need to brush up on my CAD skills. It's truly amazing, when I was in Highschool between 2002 and 2006 my school spent maybe 25 thousand dollars on a robotic arm and a CNC building machine. I'm not even sure there were many good commercially available 3D printers, although we did learn that they existed. I don't know if the robotic arm is necessary anymore, but it's truly amazing that CNC milling machines of probably equal quality are available for only a couple hundred dollars. I remember having to somewhat manually program the tool paths. Your assessment of the state of 3D printing and computer aided manufacturing 10 years ago was spot on and it brought me back to using Autodesk inventor with the US version of Junkyard wars playing in the background. Keep up the good work!
SO a Stirling engine could be used to run a generator which could drive an electric motor in an EV, A lot more range and WAY cheaper than using lithium batteries.
Good shows. Thanks. Id like to warn you.. You will soon be banned at burning, wood, gas, or diesel fuels by the end of the year.. Need to concentrate your ideas for heating with better wind and solar.. Before you know , it will be winter again
Hearing you say "So much better since quitting smoking" in Luke's somewhat recent video made me really happy for you. Glad you're well and thanks for being exactly who you are Rob! Cheers 🎉
Right Rob! Thanks mate! I’m just getting into sterling engines in an attempt to assist my son with some off grid widardry for power in the middle of the desert on the southernmost end of the Rocky Mountains of New Mexico, the Manzano Mountains.
my only comment is an observation. I think you could setup some better lighting in your garage. ie. let's on a battery bank recharged with wind and solar. good luck with this competition I hope you get ĺoads of entries. cheers mate
maxwells demons -> collimator, ... saying, to optimize the engine an electronic circuit should be used to control the pressure, and point in time of turning the collimator that divides the hot and cold side of the engine. driven is the circuit by the energy produced by the engine.
Ive got the idea of having a large stirling engine, half buried in the ground in my garden. One day i will figure out how to make such an engine work with such a low temp difference.... One day
Great Videos. Not sure if anyone has tried this idea but I have wondered whether it would be possible to have a stirling engine generator where to hot side takes advantage of ground source heat and is buried, and the cold side is above ground. Should work well for winter generation if it could be implemented.
This is very interesting! I never heard of the Hoofler tube. When you mentioned that NASA used this device for refrigeration, I remembered, way back possibly the late 70s, an aunt and uncle had an AC that was accually gas fired. Could this be who it operated. This was like I said way back becasue I was very little then but do remember it.
Thank you. I never know that sterling engines were actually used as engines, though it seems experimentaly. Another thuoght about NASAs use of the hoffler tube for refrigeration, I have seen videos where, I guess, was used in RV (I from the US) refigerators where the frige is dual fuled. Shorepower and propane.
My favorite type of stirling engines is shown in your video 1698. In any case, unfortunately, it is not for generating energy for home. As example, your design: it is needed about 30-60mmHg of pressure to fill a balloon. Volume of air compressed is about 0,0003m3 per engine stroke. If engine makes 2 moves per second then you will get about 2m3 of pressurized air per hour. It means that you will get about 500J of potential energy per hour. If efficiency of engine is 1 percent then you can get 0,5J of mechanical energy (equivalently about 0,0002 Wh).
Free-Piston Stirling Engine with more power output works with 100bar of pressurized gas that requires very expensive design. Also it will consume a lot of fuel to get enough heat energy.
A fascinating phenomenon with combustion engines is if you offset the centre of the cylinder head in relation to the centre of the crank you cause the power stroke to be larger in terms of degrees of rotation and shorten the exhaust stroke by the amount gained on the power, this is of course with a 4 stroke engine and a Stirling that rotates a crank is only 2 strokes, so we can extract more work but at the costs of some vibrations. The thing I really like about the Stirling motors is that the pistons can be made out of graphite which acts as its own lubricant inside the cylinder and if you have a long stroke and offset cylinder the side loading forces on the power stroke are reduced and since the power levels are lower than an internal combustion engine the amount of material is reduced and the types of materials don't need to be ultra processed
Allpowerlabs is a company that sells palletized wood gassifier fueled internal combustion generators. I have no idea how the company or generator are to deal with but they have been around for a while now.
Good exploration of concepts on this channel. For a while I've been wondering if Rob has implemented any of these concepts as functional day to day practical systems? If not, why not....hard to get permits or just hard to implement in a practical way?
Looking at your balloon sterling, got me thinking, those 30gal and larger pressure tanks that work with well pumps are just a flexible membrane in a can... just larger, .. how can I use a scrap well pressure tank to scale that up to something cheap yet practical?
Great idea Rob that could be real good for anyone who wants to convert the heat from there wood burner to charge off grid batterys! Is there any thermoelectric devices that could sit on top of the wood burner?
I want that sterling engine from the Chevy!!! I read there was two made! Had enough torg to spin the tyres(on dirt though). It would be a bolt in replacement for my old Chevy!!!! I still have a clipping about it from a ~1985 popular mechanics ( or popular science, I forget) that I keep taped to the trunk (bonnet?) lid!
The invention Stirling made was using a regenerator in a heat engine, so if you want to be very strict you could say: "It's only a Stirling engine when there is a regenerator in it.".

@@ThinkingandTinkering Really? I'll have to look that one up. Never heard of it.
Why cant you buy a wood fired power generator. Or bio diesel one. The fire could run a steam engine or sterling.
Allpowerlabs is a company that sells palletized wood gassifier fueled internal combustion generators. I have no idea how the company or generator are to deal with but they have been around for a while now.
you can
Good exploration of concepts on this channel. For a while I've been wondering if Rob has implemented any of these concepts as functional day to day practical systems? If not, why not....hard to get permits or just hard to implement in a practical way?
permits are always a pain mate but here we really just explore concepts
Looking at your balloon sterling, got me thinking, those 30gal and larger pressure tanks that work with well pumps are just a flexible membrane in a can... just larger,
.. how can I use a scrap well pressure tank to scale that up to something cheap yet practical?
you are talking about accumulators?
@@ThinkingandTinkering diaphragm tanks , I don't know what they're called over there..
Great idea Rob that could be real good for anyone who wants to convert the heat from there wood burner to charge off grid batterys! Is there any thermoelectric devices that could sit on top of the wood burner?
I have done videos on that topic mate
@@ThinkingandTinkering thank you Rob, I'll check them out!
I want that sterling engine from the Chevy!!!
I read there was two made! Had enough torg to spin the tyres(on dirt though). It would be a bolt in replacement for my old Chevy!!!! I still have a clipping about it from a ~1985 popular mechanics ( or popular science, I forget) that I keep taped to the trunk (bonnet?) lid!
You were close,in Britain boot=trunk and bonnet=hood.
@@ravenmad9225 is it tires or tyres? Or am I thinking of India?
it would be awesome to have lol
Can we really call all these heat engines "Stirling engines"?
yes
Stirling engines all work by heating and cooling air. These engines may look pretty different but that's the principle behind every one.
The invention Stirling made was using a regenerator in a heat engine, so if you want to be very strict you could say: "It's only a Stirling engine when there is a regenerator in it.".
