Painting the top surface of that sterling engine flat black would help it absorb more heat from the sun and may create a greater temperature difference. I was not aware these worked with cold/hot and hot/cold. I always learn something new here.
Could also paint the top plate black and stick a dome over it, like a greenhouse. Use a fresnal lens
for sure mate
Endless innovative technology
Mind blown. Simplicity at it's best.
lol - thank you mate
@@ThinkingandTinkering your welcome. I been mega busy lately hadn't watched much on the tube for a few weeks. I've been building.
I forgot how good you guys are.
Please never stop, all love guys.
When you did the previous video I thought for sure this would be the next step and so it was. Now the only thing left to do is take the rocket stove, and the cooler put some barrier between them and make a larger sterling that can generate real power lol. Keep it up, I know a lot of this already but I enjoy seeing it in action. You do a good job of explaining things and building them. I wish I had enough space and time to do the same
I won't use this mate - this is just for folks who want to experiment - I will use the heavy duty aluminium Stirling I made when it comes to the rocket stove
Rob can’t just sit around when he has an idea. And we all love him for that. :-)
And after he's done the idea, he usually finds a way to stick a generator on it.
lol - I can be a bit manic lol
lol - damn you know me too well - guess what's next lololol
Sir, you are a true professor. A real teacher, congratulations
wow - thank you mate and thank you for taking the time to say that - cheers
Leaving the world a better place than you found it . Thank you for teaching me new skills I really appreciate your lessons.
wow - cheers mate
Wow!! You are so ingenious!! Never thought that you could do it this way….I did buy one stirling engine , but running it on a cup of hot water stops being fun after a few times! This method is ingenious to keep it chugging away on my window sill!
Was just discussing a similar setup with a friend and Robert obliged with this. My Sterling obsession deepens, many thanks Robert amazing content much appreciated
lol - cheers mate - happy to help when I can lol
@@ThinkingandTinkering Just ordered two of the low temp, tea cup powered, sterling engines. One for me and and one to donate my kid's school. Will be joining your channel as way of supporting your sterling efforts. Just need to sort out a better account to use and I'll be joining soon
Stick a sterling engine on this channel you could power a huge community.
lol for sure
It's nice to see it in practice working. Good vid.
cheers mate
Great stuff, Rob!
cheers mate
Brilliant. I had this sort of thought after your vid yesterday.
I ran across a vid recently explaining pop-pop boats, as I was wondering if the concept could be used for a solar water pump. but I was surprised to discover they work like a stirling engine with water being the piston, which was pretty cool.
It seems like that notion, with a blacked metal tank for your "boiler" and the evaporative cooler for your cold side, would be pretty easy to rig up. I seem to recall you made a liquid piston one out of tubing didn't you?
(incidentally, on the water pump, I came to a Maybe on that, if one added check valves to ensure the water only flowed one way, sort of ram-pump style. It seemed like a potentially useful concept.)
I did mate and I agree the is a potentially useful concept - thanks for sharing it
I bought one very similar to Robert's many years ago. It would work if placed on your body, which could look a bit freaky, but very impressive. They also work if you stick them on an ice cube. Always wondered why they are not used more in solar energy. As usual great vid from Robert.
they are impressive and used quite a lot in solar - just not home solar
Robert lovely video, I didn't realize that it worked on both hot AND cold surfaces so thank you. Sorry, but a quick Amazon link would be so helpful so we could be sure we are not going to buy an inferior product to get the same result you are showing. Just saying, ATB
Amazon only has 2 models in that style and they both are the same price and probably made at the same factory. One of them is sponsored by Amazon so I would probably get that one in case there might be some difference, which I doubt.
if I do that mate youtube restricts the video as it then contains product placement - so - sorry about that
I imagine a wall to a building designed to deliver the temperature gradient between outside and inside to multiple Stirling engines built in the wall.
Thanks always.
That would be cool! pun not intended lol
Great little experiment as always Rob. Here's an interesting idea that might be worth a go, how about using underground temperature difference vs ambient air to run a Stirling engine too? Obviously ground source works as we know, but might be fun to show a working example with a stirling engine to see the mechanics of ground source temperature differential recovery even on a smaller scale.
I like the idea mate - I will give it a bit of thought and see if I can come up with something - cheers
Toying with a similar idea, seasonal or day night cycles would fit in well . Many thanks for the inspiring vids Robert
Great idea
This will be so fun in the winter 👏🏻👏🏻🏆
indeed
I think I'll get one of these for the kids along with some magnets, a coil and dig out my multi meter...
now you are talking mate
Nice video, thanks for sharing it :)
Very nice idea again Robert. Just thinking back to another idea of yours, I wonder if placing very small neomagnets on the wheel to react with a coil mounted so they intersect with it will produce enough to light an LED.
oh nice - I would think so mate - that's a cool idea and easy to do - I am on it lol
The SE has always intrigued me. Place a bigger version of the SE on a Rocket Stove with small boiler, and we have a very efficient steam engine (locomotive?!?). 😊
I guess so - Stirlings are fascinating machines for sure
I actually have that same model of Sterling engine. When it's cooler out, I can get it running off the heat of my hand alone.
Nice vid. I think that mug needs a wash 👍
I wash it once a year if it needs it or not mate lol
@@ThinkingandTinkering 🤣
That's just great! 👏
cheers mate
Are there any drawings, plans available to build a large stirling engine that puts out meaningful energy? Imagine this things strapped on to the exhaust of a vehicle engine which is like 800 deg C and the IC engine has 80% efficiency in producing and wasting heat which this thing picks up and turns into usable energy. Or imagine a satellite dish focusing the sun onto one of its sides which is blackened while the other side is dipped in water or connected to a heatsink buried deep underground. So much savings. Or even off grid survival.
I was hoping to see one of those sterling engines that has an alcohol flame normally powering it and see you pop on your rocket stove, I guess the one you have might work but I'm concerned about the rocket stove getting too hot for the low temp model
Good point. Maybe some kind of intercooler could work.........how about the engine runs a fan to make the fire hotter which will in turn generate more power? Just a thought
oh - the ltd won't last on a rocket stove mate - you need something that can cope with 4 - 500C - a bit of plastic won't do that - this isn't on a rocket stove - it's just on a brick wall outside
Hello diy heat sink
I’ve got a Kontax KS90 Solar, it’s been running pretty much constantly for 11 years now.
awesome
That's awesome!
Could you make Stirling cells? String a whole bunch of small sterling's together like the wind wall and get a combined output?
yeah I would think so
nice work, that was fun
cheers mate
How about drilling some horizontal holes through the oasis block, and plumb them to a black painted flue pipe as a solar chimney. A rotating elbow at the top with an expansion cone exit to draw air if you have wind but not sun.
that would be much better - this was a pretty poor version and if it works anything you do like you suggest is going to improve it for sure
I love tinkering with them.
what's not to love lol
What was the number of the video you made about phase change materials? Doesn't urea get cold when you wet it? It would be neat to see if that could be integrated into this evaporative cooling system. Something combining phase changing materials, heat pumps, and AC, would have plenty of buzz words for the UA-cam algorithm 😁.
I am not sure but it might have been 1269 - but I also did the zeolite thing and that would work well here - heating or cooling
@@ThinkingandTinkeringIt is, thanks. I was thinking that besides the diy AC,. Maybe the cooling reaction of urea could be used on the rocket stove Stirling engine? If it could be cycled to cool the cold side then be dried out again by the heat of the stove, maybe it would perform better than just a water jacket.
Have you combined that stirling engine design with a solar water heater and a generator and measured its output in kwH?
Fence posts are cold at the bottom and hot at the top, please try a stirling with one.
for sure
hey, i read somewhere you can also reverse use the Stirling engine. so instead of a generator on it, put a motor on it. would result in one side getting hot and the other cooling down, making a heatpump (or AC). Do you have any experience with this?
never tried it mate - but I did read ups on it a bit and from what I can tell there is a bit more too it than that
Add a Stirling Engine to a geothermal well. A decent temperature differential could possibly generate a useful kWh.
it could well do
I live in on a farm in australia…quick question, my dam water temp on the farm is 7c under water and my fresnel lens can boil water on a plate above the water. How much power could be generated from your engine with 93deg c difference. Thanks for your video.
Build one and find out
no idea - why not give it a go and let us all know - cheers
What about driving a 2mtr solid metal pole in the ground and attach the sterling to that. I’d think that would increase the temp difference and give the engine better performance throughout different seasons
nice idea mate
I'm impressed! I wonder if it would be more effective with alcool fumes as a medium gas in the engine. I alsi thought about the african hut chimney and cool air someone mentioned and I think a variant with tubes running just below an evaporative field would be very efficient.
I like the idea of a low boiling point fluid mate - I am pretty sure that would work well
Could be fun if you showed how you can use a Stirling Engine as a heat pump.
ok - I wil have a think
I don't get why we don't use sterling engines to generate power from waste heat. Instead we use additional power to run fans or to pump coolant.
I don't know why either
Could you submerge a Stirling engine below the ground surface and have it work in summer, when the ground is colder than the air, and winter, when the ground is warmer than the air? How big would the engine have to be in order to take advantage of the below ground temperature and the air temperature? Is this doable?
seems the next step is to combine the plant pot fridge with the sterling engine :)
or sure mate
And just like a motor can be a generator... a stirling engine can be a cooler/heater. Same principle that drives cryocoolers that some channels use to get liquid nitrogen with.
Makes me wonder how cold a "toy" engine would make a minifridge if driven with a small motor. Perhaps it's time to visit Amazon and find out? :P
that would be awesome to see - go for it mate
Could you explore the possibility of using steam to power a sterling engine using heat from a mirror array or other reflective material? I feel there is huge potential using this design on a small and large scale. Thanks!
I wonder if a closed loop system would be more efficient to conserve water?
sure mate
@@ThinkingandTinkering There was a large project in Arizona that was ultimately shuttered, but it had a large array of mirrors that would move throughout the day to concentrate heat on a central boiler on a tower in the center.
I've always wondered what would be the output of one of those Amazon sterlings, with a small gen/cap set from one of those hand crank generators. Won't be able to use the gears tho lol
it won't turn one of those mate
Film nam się bardzo podobał
If you could put it in a transparent contain with helium gas, would it be more efficient than regular air?
I believe so
Robert the earth at a meter in depth remains at 4 degrees so a shaft connecting the 2 chambers should work summer and winter
I have mytspade mate lol - I am thinking of giving this a go for sure
@@ThinkingandTinkering maybe some one close to you has a mini digger that watches your channel put out a request
I'd imagine copper pipe between cylinders althoug expensive would best and the more the merrier
How about using the sterling engine as your heat sink for you Peltier device?
and get more output? interesting - cheers
sticking it to a big CPU cooler, upside down, then covering the cooler so the sun light isn't hitting it, might be running good ! with some thermal paste in between of course, now I'm thinking, with a big enough cooler it might work on low sunlight ! of course the big CPU coolers are rather expensive, so it might not make much sense from a financial standpoint, unless you build on a large scale maybe and use the fans for another project (like a fan wall), some are cheaper though I think arround 30 ish, so we can imagine maybe 6-8 of them stuck to a huge heatsink, be curious to see what kind of output it could generate, would be nice to be able to get high quality cheap stirling engines
I like that idea mate - it would certainly improve it I think
@@ThinkingandTinkering Glad you like it, I'd be curious to try one day when I have the budget, in the mean time I could experiment on a small scale, here is the best and cheapest cpu cooler : Cooler Master Hyper 212 according to many, I remember I even saw it at 35$ once, but its arround 40 ish, although this is still a "low end" cooler, I'd be curious to see the difference with a high end 1, those cost arround 100 or more $ .. (like the noctua NHD 15) I was also thinking.. perhaps there is a way to use car engine radiator and somehow adapt it for such a project.. even better for a large scale project if you can find a truck or even tractor one (not sure if the tractor engines have coolers but I think it should..) and then the problem is these use liquid cooling so it might be a bit tricky to adapt it to such a project, just thinking out loud there, it would be much easer to just stick a sterling engine to a passive heatsink I guess ..
I love to scale up a sterling for elec gen. I want to use the waste heat from PV panels to drive a sterling
@marthale7 I love that idea of misting, a lot simpler to implement. It could be an intermediate step before adding a complex heat exchanger & pump.
nice idea mate
Great idea
How large can these be made like could ya make them 3 foot tall or 6 or 20 and have them work
Surely the radiation-absorbing black should be on the top plate, shading the oasis and allowing air to flow over the oasis to better cool it...?
it would be better if we turned the Stirling upside down
Just saw a video from someone using well water for their AC cooling system. They claim to get 72 F when it's 90 F outside with poor roof insulation. Pretty interesting.
That is interesting. I haven't seen that. Is it on UA-cam? We have well water and a spring on our property, that has very cold water.. That would be interesting to see.
it sounds it mate - cheers
Would coating to top side of the Stirling with a Matt black paint improve the sun soak?
I think so yes
I wonder could you make a Sterling engine using an air conditioner because it is hot on one side and cold on the other
I would think so mate
@@ThinkingandTinkering I wonder how much power you can get out of it heck you can even use a refrigerator but I don't know how practical it would be but it sounds like it would be practical
Magnifying glass in the sun directed on the hot side to make it a lot hotter and increase the temp difference?
absolutely
Would it be possible to build a brick rocket stove cooker/water heater with a Stirling engine generator that could have a feed in from a rooftop solar thermal array or is that way too ambitious or would steam be easier/more reliable? Also does anyone know why Stirling engine generators are not available for sale? Any company that has tried seems to have disappeared.
it's possible mate - but it seems a little like overkill to me - but possible.
I was looking for a big stirling engine... 50 to 100 kWh... it looks mission impossible :(
I have seen big Stirlings and Stirlings of power in that region - the Swedish run 2 submarines on Stirling engines - but the challenges of building a large engine are the same I it is a Stirling or not
hi how about putting a fan on it best regards
for sure
👏👏
cheers mate
@@ThinkingandTinkering you really are an oracle of knowledge Robert.. I love all your videos!! I'm half way through a gravity generator thanks to you and people like you..
Really grateful you share it with us. Thank you so much!
So enjoyable, you're a great teacher👍
how about diamond power
Sterling engine are good at pumping water. They are very efficient. But a lack something called torque. I think.
stirling engines have been used for all kinds of things from the 1850s on - and there are quite a few designs - worth looking into the history a bit mate - if you are interested
@@ThinkingandTinkering I have.
Try this with your NASA Stirling engine! Will it work??
it should do - all Stirlings work on the same principles
damn im never first huh
you have to be quicker mate lol
👍👍👍
cheers mate
low power sterling engine ;D
ltd = ltp
