Precision Twin Cylinder Stirling Engine

[mostyle70]

I wonder why this was'nt put in mass production makes you think!!!!! It's funning how we have the things that can change the world for the better and they get shut down meaning stopping it's growth.This along with other great inventions can help us and really help developing countries of our world.In the 1800's it was invented that long ago and today the excuse is what ! Nice Post.

[ZebbMassiv]

would be cooler if you could make it produce electricity. at least make an l.e.d. glow

[01EliteMr]

how long does it last?

[gyroscopes]

@01EliteMr until you remove the heat.

[chucknorrisrules23]

sir i will write you a blank check

[jfdomega]

@ wyrrox..... Lmao!

[mrbluenun]

Hi gyroscopes,

I am impressed with your twin engine, Did you make it or buy it? I am interested in any engine particularly huge to gigantic and very tiny. Do you know where a Sterling Engine does a job of work, because I have not heard of one? Your device, well cool!

Take care

mrbluenun

[gyroscopes]

@mrbluenun I actually sell them. Stirling engines can used for power on subs. They have been used to cool fridges. They used in expensive home boilers to produce electric power.

There is even the Vulcan Stove Fan which is a stirling engine and blows heat around from a stove.

[piccolopeteisme]

@gyroscopes I like it and I've seen others designed the same way - only larger and they appear to operate in basic ambient temperature provided it is a hot day. Umm, how are you gonna sell yer stuff if you don't tell us?

[gyroscopes]

@piccolopeteisme As long as you have a few degrees temperature difference they they work. That can be a window sil. Your hand. On a stone slab. On a set-top box.

[TheMontanaDave]

I found a great use for stirlings. We have a wood burning stove at home for heat. Problem is circulating the air.. Ah ha.. Stirling on top of stove with a lil fan to the rescue.

[gyroscopes]

@TheMontanaDave Yep Type Vulcan stove fan in to google.

[TheMontanaDave]

Air is not "A" gas, Its a mixture of mainly Nitrogen, CO2, O2, CO, Argon, and a few other noble gases.

[mlopinto2k1]

There has to be some sort of gas in the cylinder. Air does not expand and contract.

Thewizzardof9 <----------- LOL! This fucking made my day.

[GerbilEssences]

That looks ready to pump crude oil.

[wyrrox]

Wait a sec... If you only need you hand's wormth to run this and you live with your parents which provide free food. That means free energy! :D :)

[Thewizzardof9]

there has to be some sort of gas in the cylinder. Air does not expand and contract. people use different types of gasses I was wondering which one you used?

[gyroscopes]

@Thewizzardof9 Air. Stirling engines are hot air engine. It works on expansion and contraction of air under the due to temperature change.

[mj9287]

@Thewizzardof9 Actually air does in fact expand and contract.

[mj9287]

@Thewizzardof9 Yes "Air" does in fact expand and contract with varying temperatures.

[12ericmier]

@Thewizzardof9 air does expand and contract. air concists of what ? different kind of gasses.

[jdxcc]

@Thewizzardof9 Never heard of an air compressor?

[MalliganTheUFO]

@Thewizzardof9 Ha ha ha ha ha ha ha ha!!!!! Then why do hot air balloons fly in the air??? Hot expanded regular air I thought?? lol

[Thewizzardof9]

very nice. what gas did you use, it expanded with very little heat.

[gyroscopes]

@Thewizzardof9 Air. No gas.

[BobStinkfulla]

@gyroscopes Air is a gas.

[Fuzzycop]

@gyroscopes I hate to tell you, but air is a mixture of different gasses. ;)

[gyroscopes]

@Fuzzycop In that case for the pedantic: I used roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide

[Thewizzardof9]

very nice, what gas did you use?

[Anthonyk312]

@Thewizzardof9 air is a gas

[tyronesantikaTV]

i want one!

[HybridWaterMan2]

Om man- I want one of those! That is a beautiful mechanical piece! I don't car if it doesn't make enough useful energy- it's just cool to watch!

[ltrmstrfn1234]

so this engine will continously feel cold?

[tv205]

There is a company by the name of Sunpower in Athens Ohio they have built a striling engine capable of 6kw and can fit into the basement of the average house.

it uses only one piston and a linear alternator...Truly ingenious

[mindthoughts1974]

Very very nice indeed. Thank you for sharing this video with us :)

[TheHouseBlog]

excellent machine work!

[Stunts08]

way too cool i want one!

[macedonianimation]

running on the heat of my hand? wow!

[KrankieV2]

That is an excellently made model sir

[WickerMouse]

What is the clearance between the displacer and the walls?

[MrRepulsiv]

Swedish submarines have a fully working stirling engine for quiet operation, so its fully possible to build and use it, but as all engine types they have their good and bad sides.

[055BIGTHUNDER]

that's awesome

[Oglaigh32]

Beautyfull engenering very good

[MrDorfmann]

Only on the heat of your hand ? That´s certainly an achievment !

Geothermal heat should easily run it.

[BenjaminAKozlowski]

This is beautiful. Did you build it yourself or did you have plans. I would love to build one just like it.

[dzgfdg]

wht if ur hand is nearly always cold. ive got poor blood circulation

[snowman3514]

WOOT 0.0001 HP useful!

[qpad74]

Kockums in Sweden built submarines with sterling engines...

They are in use with the Swedish navy ツ

[rubbertrollop]

these engines can run on a temperature differential of 0.5K - surely a simple solution is to utilize marble which is around 6 degrees cooler than it's surrounding environment...

[StabbyMcButterPants]

The major problem with Sterling engines is that they cannot produce enough torque to be converted into a useful working energy.. well, unless we made a Sterling engine 40 stories tall I guess.. But using that much space and materials to create such a monster would be in the end counter productive. and wasteful. Way back when, they wanted to couple these on geothermal ducts, but why do that when you could just convert steam to mechanical energy or electricity.

[gyroscopes]

@StabbyMcButterPants They have been used to power cars. There are stirling engine farms in the US producing power and their is even Vulcan stove fans that use the heat from the stove to blow air around the room.

[robicool]

beautiful design

[walk2theend]

Where can I get one??

[markdem]

very cool indeed. i love it

[gyroscopes]

@markdem gyroscope com

[LeonPhythian69]

nice build that looks awsome

[TheGoodInventor]

Faaaaantttaaaaassssttttiiiiic

[prairiedog1967]

I have seen only small versions of this. (this is one of the best) Is there any larger versions out there? something that will run an automotive alternator, or generator?

This is a great looking sterling engine!. Just need one on 10X scale.

[Rayrockny]

Why cant we drill deep into the Earth and use the cores natural heat to power thousands of theses engines on a much bigger scale, free energy? or am I mistaking?

[thundercatzr]

so is this a perpetual motion engine?

[gyroscopes]

@thundercatzr NO

[MrGoogfan]

Ive seen may stirlings but that is a really nice one. Where did you buy it?

[SteveBracy]

OK, now just scale it up to make 2,000MW (2,690,000 HP) like your local Power Station does.

[seanbrockest]

@railrdr523 I too would like to know this. I want to buy one, but i want to make sure i get a good one. Where is a reputable place to buy them?

[Axtitios]

DUDE I WANT ONE

[JesusHChrist2000]

that is a beautyful machine

[sonyxploder]

I wish these things didn't cost so much. I would love to have one someday.

[megaverse]

it works with heat ?? hmm ok if you ever plan to give the blueprints i'm quite interested to see how it works ...if it's not all ready an existing tech i just didn't know about

[bonsai108]

You sure it wasn't the heat of the sun reflecting off the base?

[gyroscopes]

yes. I'm sure.

[enersium1]

btw, where can you buy something like that, i like it :D

[screwbushcomegetme]

i have seen so many rediculous videos im going to put up my own site and link to the real deal vids. your device is neat but looks to be propelled more by the shaking of the liquid than heat. styrofoam in liquid?

[frosty9595]

Fuck did you even bother to look up what a stirling engine is screw? They are so efficient they will fun on less then a 4 degree temperature difference between the plates

[badbenjy]

not a liquid...

[g0fvt]

You seem to think the chambers have liquid in them, they don't. The styrofoam material is an insulator, as it is moved from top to bottom it isolates the source of heat and cold alternately. (relative terms) The air inside consequently expands or contracts causing the piston to move, this in turn operates the styrofoam thing (displacer) causing the cycle to be repeated. The Stirling engine was invented by a priest who was concerned about the dangers of steam engines.

[WORMSStube]

I thought there was no liquid in sirling engines.. just air/[or another type of gas]

[mundorganic]

@screwbushcomegetme

You need to do some more research on stirling engines before you criticize the video. These engines are very real.

[Helena1120]

wow your dumb, theres no liquid, its air, and this is a "real deal" vid. its called a sterling engine, look it up moron.

[minion882004]

not sterling. STIRLING

[powermaks]

how dos it wrk?

[onionmon]

whats your HP on that rotation?

[bakemycherrypie]

were do i buy one?

[bladeb0y85]

dude that scary it goes up and down up and down up and down

thats realy scary

[bingoberra18]

You say its efficiency is 50% But 50% of what energy? Is THAT thing making 50% of the power from the heatloss of his hand?

[RestauranteChines]

Only with the heat on your hand? amazing, I really wanted to buy a small one like that twin or single, just to loooook at it when I get bored :-) .

[impavitus]

could use that over thermals in Greenland? That would be a good use of energy.

[Dirtboy101]

This a fantastic idea!

[jamiegoddard4]

Has anyone ever made one that runs off its own friction.

[jamiegoddard4]

Wow, flames and magnifying glasses are one thing but to run it off the heat of a hand.

[ClannerA01]

Wow. I've seen diagrams, but i didn't know it can spin that fast.

[cornerblu]

it appears that your middle finger is pushing the left piston rod in order to help spin the wheel, nice trick. As you turned the device, it slowed a bit, and when you turned it back it picked up speed, this is caused by your finger losing its rhythm as your turning it. Nice conversation piece though.

[olidz]

it appears you don't know what a Sterling engine is :D

[mrcss]

It apears you dont know how to spell Stirling

[revelinabandon]

Stirling.

Good remark though. (8P

[danway60]

If you've ever tried spinning anything on a pencil or something and then try to move one side up or down you will notice that it slows down quite alot. This is the same with anything that is spinning. It's called the laws of physics. I've just made a two working engines that run on compressed air and if you try tilting them while they are running they both slow down.

[illustriouschin]

never been to a chemistry or physics class huh? so sad

[Achtelnote]

you are so stupid.....lol.

[TryforApples]

The entire contraption is sealed, both on top and bottom. There's nothing for him to push on. It's a precision sterling engine, when they're sealed and very well made, they can operate off a very small temperature difference, the heat from his hand and the cool breeze for instance.

[KC9PBI]

cornerblu You clearly don't know shit about physics.

[jreineke2]

this is a low temp Stirling Engine it is able to run off the heat of his hand, there are many examples on YouTube of similar engines running off of hand heat. he finger has nothing to do with it.

[rillip3]

Look it up, Stirling engines are for real. They're low torque external combustion motors. They can work on a very small heat difference, like between the palm of your hand or the outside temperature, but are also made like locomotive engines with large fires powering them.

[421court]

idiot

[Fawad70]

Is that machine effective under any load?

[beatmaster8000]

Stirling engines are some of the most efficient engines there are. If you gave it enough energy input, it is more effective than internal combustion engines. Which is why they are often used in power generation. You won't find them in cars, since they take a long time to 'get going', although prototypes have been made, and were more efficient than internal combustion engines.

[costi08]

masterpiece :|

[RamoneTalarico]

incredible design! work of pure genius!

[intheshitter]

How efficient are these things ?

The design of this is amazing. I can picture one at a huge scale out in a desert generating some serious power :)

[dolaggressor89]

close to the carnot efficiency although I'm not certain how high is it, can be from 27% to 50%. I would not dare to say as high as 80%. Anyhow, it is extremely efficient but has poor power to weight ratio. On a larger scale, it can be extremely big and heavy to run but certainly it has a future due to low operation cost. It has extremely high operating cost is also another downside.

[joelito101]

ok, enough of the negative points, now focus on how to make each of those points positive since you were able to point out each one of them with such certainty.

[caligor89]

cant u use the solar oven as heat sourse and put a sterling like this on top of it ?? heat= oven? cold= normal air? would u not get a got output of that ? .....

[Mgjaggers]

Do you think it's possible to have that run off the heat of the earth?

[gyroscopes]

Yes they need as little as 3 degrees difference.

[v5dan]

For the non believers, this really does work, it uses the principle of heating and cooling the air trapped in the large glass cylinders, the bottom plate heated by the hand causes the air to expand, and pushes the smaller drive piston up then the air is forced up to the cold plate, it contracts causing a vaccuum and pulls the piston down, very clever invented by Rev Robert Stirling. Pure Genius.

[Cindermakers]

I will purchase this from you/

[Shamanestr]

beautiful !!!

[grsmonkey]

Wow...that's the prettiest Sterling-Cycle model I've ever seen. Fantastic craftsmanship...are you building these things!?

[seriesioo374]

will this work on large scale

[ooqqooq]

where the power come from?

its so cool!

[seneca65r]

The power, as stated, Is coming from the heat from his hand passing from the lower plate to the cool, cooler upper plate. Yes an amazingly small temp differential. This is why this is such interesting technology.

[Timthegreat2]

Witchcraft!!!!!!!!!!!!!!!!!!!!­!!!!!!!!

[gyroscopes]

hmm well it depends how you look at it.

Is size is important then these are not really the answer say compared to a combustion engine. However in terms of efficiency then they seem very good.

[jravagojr]

I think it is better if you explain to us how you make that machine..thanks

[toadabc]

I am constantly amazed at the variety and beauty of these engines.

[crazyboy123252]

put it ner a fire

[0453567]

I wonder if you could make a more efficient "mechanical" solar panel with these. Current photovoltaic solar panels are very inefficient, but these might be more? If so these could be revolutionary?

[gyroscopes]

They already exist.

[spitgalore]

What are the white moving parts? Thanks for sharing this wonderful mechanism.

[gyroscopes]

pistons.

[gonzon22]

work of art. bravo!

[popupwool]

Where's the heat source here?

[gyroscopes]

My Hand.

[lllusionx]

"great, now we must keep i from the serfs, lest they gain literacy..."

serf:"'ey, wha' is that my lord?"

"NOTHING!!"

[goedaschaugst]

Good work,

john

[timerider4]

Set it on your hand and put ice cubes on top and it will run even faster.

[zevn7tp]

Having a hard time believing this one. Break it down and show all the parts to prove there's no motor and battery.

[Grimdopple]

no its real, just google Stirling Engine,i remember making one for highschool. but other then looking nice, its pretty useless

[MelaMan]

I disagree that this machine would be useless! It has countless possibilities, including a water pump in areas where electricity is hard to get or non-existant; an air-pump for caves or damaged quake buildings; or even as a fuel-free electricity generator!

[WhichDoctor1]

I have seen stuff on the web about cooling fans for computers using this tech. there are lodes of small scale uses for this.

[MattChez]

why dont they build massive versions of these and put them near geothermal vents?

[bluetorch13]

ok... I WANT ONE!

[Pacober1]

awsome, figure out a way to make it bigger and put it over a geothermal area like in ausralia maybe, i dont know. it probably wont work...

[TheHermeticAlchemist]

obviously you do not know how sterling engines work. with the transfer of heat to cold and heat to cold makes the pistons work, now you might have something about using geothermal area, but where would the funds and resources come from to build such a gigantic one? I do know they are currently concentrating solar energy onto sterling engines using different methods and generating electricity.

[Aliasnamekk]

wow that's so cool

[sirnubenegra]

now, that is something! great work. pretty soon you might see a car propelled by our body heat. great job!

[Coffeeeggsbacon]

think of the size of the hand compared to the size and weight of the flywheel that is being powered by that engine. you would need a lot more heat than what is generated by one person to power a car, and it's still a very low torque slow engine, it would not be practical, if not possible.

[krizla4]

uhu ... like that's gonna happen :)

[BarkingSin]

I'm envious of the low temperature there, here in Taiwan, over 30 centigrade degree, impossible to run the engine by hand heat...(orz)

[BarkingSin]

Well...

Is it run by your hand heat, or sunlight?

[gyroscopes]

heat from my hand. Although it can run from sunlight.

[SBha30]

Cool. Has a large scale electric power system been developed using this approach? There is a large lake in southern Utah (I think?) has mountain water at a consistent 40 degrees in a hot dessert like area. I remember seeing it on the travel channel. Has huge temperature differentials year around. It seems like this system would be ideal this location. Thanks for posting this.

[gyroscopes]

Only really a few systems. Theres lots of work being done on these types of systems at the moment.

[gyroscopes]

stirling cycle. basically heating and contracting air.

[gyroscopes]

Building plans? Sorry no. It comes prebuilt.

[antoshkaster]

Wow!

Do you have plans for this thingy?
