They don't work very well
ATerribleArtist
I got my dad a see-through kit variant of this with 2 pump cylinders for Christmas. He absolutely loved how detailed it was to build.

There are some -80 C freezers that utilize Sterling engines. Unfortunately they are not powered by a Starbucks mug...

This Labor Day weekend if Covid is quelled come to rollag MN and see sterling and steam engines in action authentic and old but still work
nkbaron808
Yeah.. teabag it.. nice and easy

Some YouTuber needs to make a video of how much HP would be derived from arranging hundreds of them

I had a post with one of these from my Secret Santa...it got nowhere. Glad you could make it! +1

Fun fact, sterling type engines are sometimes used in submarines due to how quiet they are
VosperOfAntarctica
awesome. My brother got me the exact same one!

Being the awful pedant that I am - the black puck just displaces the air alternately towards the hot side and then the cold side. The /
tanebot
piston is at the back behind the wheel, and is pushed up and down by the changing pressure as the air heats (when the displacer is up) then/
tanebot
cools (when the displacer is down). The piston turns the wheel which moves the displacer. Stirling engines are awesome, this is a nice one.

Do it in a glass cup!

Saw the mug and read Stirring Engine.

I wouldn't drink that tea afterwards though, the bottom of that thing looks nasty

Never drank out of the hose as a kid,eh?

It's condensation!

Fun story: i found my car kept getting dirty at work, with messy drips. Thought it was odd. Turns out it was condensing water from idling

I thought someone was vandalizing my car. Turns out it was me.

Do we use this technology by natural heat sources that are infinite to produce renewable energy?
jinbee
They're weak as fuck, they just about turn themselves. You get small fans that go on top of wood burning stoves, that's about it.

NASA is developing them for probes and rovers, paired with an RTG. https://en.m.wikipedia.org/wiki/Advanced_Stirling_radioisotope_ge

We have far more effective ways of utilizing geothermal energy nowadays. https://en.wikipedia.org/wiki/Geothermal_power
kittykat1988
Thank you for sharing! This is interesting to read.
tanebot
The power density is incredibly low. We do have stirling engines for generation but they're really niche.
kittykat1988
Ahh ok. I have no gauge of how much power this would generate and I assumed it would be a lot more.
rixxor95
I wouldn't say niche, Sweden uses Stirling engines in their submarines.
torillatavataan
That's a great application, these engines are nearly silent. They even sunk a US carrier without getting detected in a war games exercise.
MrE158
You don't consider a super-quiet engine for a military submarine to be niche? It's not even the primary engine on those boats.
thisguyonline1988
I love the simplicity of it. Be neat to do some home projects with them, just for "science".
EuphCat
Ooh I have this. I sticked heating element, insulating foam, and then attached a usb cable. Energy waste? Nah, it warms the room tiny bit.
HereForTheSurpriseMeat
Your quotations made me think you wanted a sterling engine dildo or something, like in Burn After Reading or Always Sunny
SomeKid
Look up SunnyTech on Amazon. They have some cool solar ones that levitate based off how much Sun they are getting. (I think)
whateverthevoicestellme
Shit there goes $40

Oh I was thinking of reverse engineering the thermodynamic properties of the design for growing veggies, but yea, that too lol
mobileimgurlags
You got some literature for ideas like this or a good reference
thisguyonline1988
Actually, most of the time my concepts skip drafting and go straight into building.

They used to use these on farms as a water pump. They would build a fire under them in the morning. Don't lube cylinder with oil or BOOM!
TennesseeTophat
Science me, bitches. What is happening, here?
yoozernaiym
A thermodynamic cycle's work is proportional to the area in its pressure-volume graph... everyone mentions the temperature differential, (1)
yoozernaiym
but no work would be produced without the pressure differential... high pressure phase disperses heat, low pressure adds it (2)
alcaray
Cool way to use a temperature differential to do work.
FlyingButtPliers
The temp difference between the bottom and top of the cylinder makes the piston move/wheel spin. Bit like hot air balloon in a loop?
StevieTheAussie
Oh, I thought it was a teabag dunker.

No it was more of a filthy lopez.

SomeKid
A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the working fluid) at
SomeKid
different temperatures, resulting in a net conversion of heat energy to mechanical work.
TennesseeTophat
Thanks for the info, kid ?
Stevefromaccounting
When the piston is at the top the air is at the bottom, on the hot metal. The air heats up and pushes the glass plunger up (1/2)
Stevefromaccounting
The glass plunger moves the wheel, which pushes the piston down and the hot air now is touching the cold top metal plate (2/3)
Stevefromaccounting
Which depressurises the chamber, pulling the glass plunger down and turning the wheel pulling the piston to the top etc. (3/3)
itsthevoiceman
The description.
TennesseeTophat
I get the what. I dont get the why. Other than its cool, and fun.
Higure
There is a bottom and a top metal plate, with different temperatures. There is a middle plate that moves up and down with the wheel. 1/?
JollyJokzr
Why doesn't it settle in equilibrium in the middle?
Higure
Because of the inertia in the wheel and the generally low friction in the machine. That's why you have to start it going as well.
Higure
There is a cylinder. These are the essential parts. When the middle plate is at the bottom, the air is in contact with the top plate, 2/?
Higure
and the air inside the machine contracts, pulling the cylinder piston down. This moves the middle plate, so that the air is in contact 3/?
Higure
with the bottom plate, expands, and pushes the cylinder piston up. Rinse, and repeat. 4/4
TennesseeTophat
Im a wrench turner, so i get the mechanical aspect of it. I guess what i was really after is the "why"?
