Twin Cylinder Engine Running on ice - Gyroscope.com

[Dubconferencedotorg]

hmmh .. just bad that in nature it is not usual, that you have a room temperature on ice ;)

[gyroscopes]

@Dubconferencedotorg It also runs from the heat of your hand. Hands are quite common in nature ;-)

[scott93257]

Larger scale that could go in some futuristic cars... With gas prices the way they are... Put the output shaft to some sort of gear reduction system..(transmission)...It would be cool.... refill the tank with a bag of ice from the corner handy mart...

Clever idea?

[Chihang256]

why does engine always has to produce sound...unwanted energy...

[gyroscopes]

@Chihang256 My best guess would be that this produce 0.00000001 watts of sounds energy. Many orders of magnitude difference from the power it can produce.

[scott93257]

@Chihang256

Because all engines have moving parts...Moving parts make noise...It 's the law of mechanical physics...study it

[MsLucas099]

cool

[kajetan88]

In stirling engine you put heat on the bottom, but in this case ice should be on top because its not ice that provides the energy, but the air around.

[gyroscopes]

@kajetan88 You can put the heat/cold on the bottom or top. It runs backwards when you switch the hot side around.

[kajetan88]

@gyroscopes Heat moves up, so teoretically it should be more effective if ice was on the top.

[TheKaos90]

@gyroscopes So you mean this can "suck" the heat from an overheated engine ? And maybe reuse it as another form of energy ?

[dfisch53]

Now we can harvest the energy from the ice caps melting and reverse global warming. Fight ice with ice!!

[OSCAR7893]

So you take this to Antarctica and it will run forever?

[DrDrdreydrey]

@OSCAR7893 it relies on a diference in temprature between the top an botom plates, so if you took it to antartica becuase the air is as cold as the the ice you would need to warm the top plate to keep it running.

[JorrieboyL]

@OSCAR7893 No, this is because the air provides the energy because the surrounding air is hotter than the ice. On Antartica the air and the ice have the same temperature, so it would not work on Antartica.

[minec123]

it got faster o.o

[cDog8766]

i feel like a dumb sht now, sorry

[johnyradio2]

why don't you make the use the oil wells on top to create friction to heat up the top plates?

[1972FordF150]

Rev it up to 3600 RPM lol

[MrSaturdayNightSpecL]

increase of scale and a stater :)

[TheDarkone1111]

?!? ... ice powered engine ... ?!?

[coolintruddle]

Neat.

[HiDefSoundandDisplay]

Thank you, I love to watch your models in action. It's soothing and they are beautiful.

[psp10004]

nice, i will put it on my desk and let the sun heat it an i will work forever if forever means til the sun goes down. lol

[PacificCircle1]

interesting crank cam

[aramhampson]

I dont want to be the dork that always tries to master everyone with their lame know-it-all style so I'll just say..These motors are really cool!

[sholtob]

if you put it on an iceberg it would run for ever, bot how does it work, please reply

[yourmamaluigi]

I wonder if it could walk if you replaced the spools with a foot like appendage?

[cDog8766]

I WANT ONE, where can i get one?

[gyroscopes]

clue is in the title

[sqhschief]

@gyroscopes Hahaha, some people eh.

[neutrinoable]

it is very agreat to see this scientific video

[TravvyG]

where can i buy one? i dont need it for anything but i want one haha

[deathmachine392]

use dry ice, it will probably go faster and last a lot longer

[brumanima]

how long does it spin with one roll?

[gyroscopes]

until the ice melts.

[psylence101]

ooh it's a little sexy

[Peppe90wlf]

VA SPARATI

[rodstartube]

haha looks funny

[blagkonijn]

I have been thinking about a 'proof of concept' on this idea:

think of a house in the snow. Minus 15 celsius, or colder outside. 16 to 20 celsius inside. A stirling engine build in the wall, producing enough watts to load your mobile phones batteries :)

Or: to boil 1 liter of water. That would be .. just AWSOME!

[FLABERGAG]

Sterling is georgous

[jcfdillon]

if you use some of your engine power to compress air, you can then run a small Ranque-Hilsch device to create separation of hot and cold air in an air pipe; the separated hot/cold air can then be directed thru insulated pipes to the appropriate hot/cold end of the Stirling engine to increase efficiency perhaps. (cold air flow can also "freeze air" solid for future "air ice" fuel for Stirling engine)

[clnmyjts]

that pretty cool ..man it taken off

perfect for frozen artic generators

[thespeedengineer]

So if i drill a deep enough hole in my back garden and manage to use my local stream to pump a small amount of water through the bore, the change in temperature could run a scaled up stirling engine, hence powering a small generator?

[TheRancherman61]

yes, but the energy to pump the water down the hole and back up again would be greater than the stirling engine would produce spinning a generator.

[gyroscopes]

I recon it would work. That technique (drill a deep bore) is already used extensively for heating systems. You can actually get quite a bit of heat that way. So I recon should work quite well.

[gschjetne]

This would be twin gamma stirlings sharing a single crank shaft by the use of yokes. I'd assume a single two cylinder alpha would be more efficient and less mechanically complicated.

[lama231245]

truly beautiful

[Dojan5]

That's cool. Nice speed and all.

[jmb0829]

where can i buy one?

or would i have to construct it myself?

[robot797]

m e wanna know 2

[enemyindisguise]

good work !!!

[bmcs777]

lol i was the 222,555th viewer and the on hundreth commenter. 5/5

[Probewitch]

You have appreciate the elegant design weather it has practial application or not.

[goofywilly]

i can see driving thru death valley and

running out of ice every 50 feet! lol!

[MisterPie1]

WHY AREN'T WE FUNDING THIS?!?!?!

[Ethkingg]

LOL

hahahahhahahahahah

[blownengine33]

What, like your going to run your car on that? Think about it

[gyroscopes]

a stirling engine powered car has been made in the past.

[Zeako7]

I KNOW!

[lazzer408]

It hardly produces enough power to accelerate itself let alone something 3000lbs heavier. lol

[gyroscopes]

The same could be said for our 3cc v-twin engines (see video clips) but when you scale it up to 3000cc it move a car quite well !

[lazzer408]

Scale that ice up 1000x also. lol

[prisoner1138]

scale up the ice, or you'll have you use a source of heat on one side if a block of ice is unavailable. And the scale required to power a car any distance is idiotic. Plus then you'd have to be creating huge blocks of ice to sell at filling stations, or alternatively somehow power a chiller in the car to keep the ice cold.

Plus temp changes in climate can drastically change the power output.

This does NOT work on a large scale in an effective manner.

[gyroscopes]

Oh dear. Let me explain. A stirling engine powered car has been made before. The engine simply replaced the existing engine. don't forget 1000x in area not in Diameter. The can still ran of fossil fuels and I beleave was quite efficient. The biggest drawback was delay before it started producing the powered required.

I suspect it would work very well in a hybrid car.

[sixmagpies]

You don't seem to be entirely familiar with the technology. Stirling engines are already developed to be considerably more efficient (ie. over 50% more efficient.) than any known internal combustion engines and are already being used commercially in the generator systems of hybrid vehicles and solar energy conversion systems.

[bobtheswan92]

Just put it in antartica haha theres a lot of ice there

[chickenpoper]

yes but the cold will attack the metal and the ice will freze the cylinders kepping it from moving

[gyroscopes]

Cold attack metal? I don't think it will.

And don't allow air around the cylinders, so there wont be any ice build up.

Techincally there is nothing to stop you doing that.

[chickenpoper]

actually cold will make the metal brittle then the winds strong winds will slowly erode the metal till it breaks(plastic to if there is plastic used in it)

[Crus777]

I dont think they would use ice for that application smarty. This is a demo... duh

[Hansolo60]

How much power could you extract from such a machine? Can you combine it with several others to power your house?

[speedstakerguy]

thats pretty kool :P

[qnaman]

Is that powered by ice melting?

[igotapochahontas]

so how exactly duz this thing work? i understand the concept from similar machines ive seen but this one looks different so i cant figure out the specifics

[gyroscopes]

Its basically two stirling engines stuck together with a single flywheel. Just consider the one side and it should all become clear.

[igotapochahontas]

hate to bug u again but after googling stirling engines i discovered that this is not at all what ive seen b4. kuld u do a video breaking down the parts and explaining it? or give me a good link? i cant find how these work and its driving me nuts ha ha

[wmorrison13]

Wow, does that use any energy?

[gyroscopes]

Yes, it uses the temp difference between the air in the room and the ice.

[tesla1961]

very nice machine,al your movies are GREAT.

[OlympicSailing2012]

wow this is so cool can you plz tell me how to make one

[unclearless]

Ok, I am a person fascinated by this. So if you had a huge version in the arctic on ice surrounded by a VLA Very Large Array of mirrors to heat a central location, with a wind shield AROUND the mirrors, not high enough to block the 6 months of sun, would that be feasible? I want to learn, and any given criticism would be most appreciated in the form of why or why not, as I am ignorant to this field, yet believe sometimes an outside opinion may still be worth consideration. I thank all in advancc

[gyroscopes]

Yes you could to that. You can also run them in hot areas with a little bit of cooling (makes more sense).

[unclearless]

Thank you for the quick response. Yet I have a question, I lived in Phoenix Arizona 6 years of my life, and it is much harder to cool something down in 122 degrees (The hottest I ever witnessed) than when I was in Alaska in very cold temperatures when the sun would shine consistantly for 5-6 months, so would not solar colletion be easier to heat in a cold enviorment, than the opposite? And energy to get cold water to a heated enviornment would that not make the process moot? I am lost on that.

[unclearless]

Why would it make more sense in a hot area than what I proposed in the arctic in my last comment, my idea would require only the suns energy for heat, to cool in a hot climate seems like it would take a lot more energy. (Like pumping water as a coolent etc...)

[gyroscopes]

Well consider the difference in air tempature between the two places. Average north pole temp is about -35c. A quick google on Phoenix, Arizona suggest the average temp is a lot less than 40c. So 75c difference. The hot side of a solar stirling can very quickly reach 500c. So you only gain maybe 15% difference in temp between the sides. Electricity Transmission losses in countries tend to be over 7%. Between a major country and the arctic would be much higher. So high cost for no real gain.

[jcobaltss2005]

thats the best idea ive heard all day. the best bet would be a hot climate, to paint the top plate black and keep the bottom plate submerged in water and in shade, or simply by raising the whole motor onto a higher surface where a sprinkler system could cool the bottom plate from underneith

[LordInksworth]

I lOVE it!

[Ericspasstime]

I would like to use one for experiments is that possible

[neiallswheel]

we need one of these on the moon.

space is cold. sun is hot.

nice big cable back to earth little pod full of interesting people sunny side up

[johnyprestige]

could this be used in a geothermal environment?

[andykins118118]

what would happen if you spun it in the opposite direction at the start, without changing the heat source?

[gyroscopes]

It would stop

[extremeIife]

That's AWESOME, great job, man.

[soupdragon42]

Cool

[0vrqq]

I am thinking about making a regular sterling engine. I was planning on putting liquid hydrogen in the chamber instead of vapor hydrogen. How well would this work I meen I know the liquid would eventually turn into gas, but the pressure would be much greater. is this idea false or is this idea true?

[gyroscopes]

liquid hydrogen? surely that wont expand? The whole point is that the air/gas expands.

[0vrqq]

No I am saying that the liquid turns into gas hydrogen inside the chamber. This is only when creating the sterling engine. The pressure would be greater but it wouldn't be a liquid hydrogen cycle. This pressure would create a more efficient engine since the cycle works off pressure. or would it really matter if it where under a lot of pressure? I will repeat the liquid hydrogen is only for making the sterling engine. Once sealed the engine would be hydrogen gas under pressure. would this work?

[gyroscopes]

So yes if you put compressed gas (most types) it will work better. You don't use liquid hydrogen when building it. You just put compressed gas in after it built.

[adisharr]

That's pretty interesting to see thanks :)

[spitgalore]

I see it, but I don't believe my eyes, thanks a lot.

[LEDvideo]

Nice,

Does that depend on room temperature to work as well?

[gyroscopes]

Yes, if the room temp is about zero it wont work !

[lejink]

so what if u hooked this up with a geothermal well? free electricity??

[gyroscopes]

Basically yes. You can do this.

[lejink]

how much torque does it produce? could it be scaled up and have enough rotational power to turn a generator u think?

[gyroscopes]

Hardly any. However the technology is scalable.

[ossumguywill]

Am I correct in saying that (not to be critical) this thing is actually a bit less efficient than geothermal steam heat and is not really a viable energy source? Does it only run so fast because its efficient?

[gyroscopes]

Hmm not sure about comparing it to geothermal steam. This thing can run from the heat of you hand. So it is efficient. variants of it are being used in large scale solar systems.

[ossumguywill]

Hmm I guess youre right but what I mean is that perhaps this only runs so well because it is lubricated, tuned, and tweaked to run well. Tell you what: try to hook up a motor to this and generate electricity. My guess is that it will just stop working because of the load, but I would be delighted to be proved wrong because then woe would have the future of energy on our hands.

[gyroscopes]

There are systems that generate electricity using this technology.

[ARTAUDIOJOTA]

You would have to change the machine size or gearing, right?

[neiallswheel]

we will need one of these on the moon.

geo thermally. the martians probably have one already. space is cold. sun is hot.

[xScHwInNBMXx]

if only cars could run on these...

[gyroscopes]

Well there was a prototype car that ran on a huge one of these.

[jerinxd]

i have never seen an engine that runs on "ice": how much does it cost?

[octaviotav]

the diferense i the temperature in the both sides produce that i am right no ???

[jrguillett2]

turbocharger it!

[Ng0zT]

how the hell does it excellerate???

that looks too complicated to be 100% mechanical...

[PerfectBlindness]

It's mechanical alright. The energy is not coming from the ice but from the ambient temperature, which is cooled down by the ice. The motor speeds up much the same way a water wheel does but in terms of thermal current instead.

[Bp1033]

That looks like it could be used as a electrical generator. Especially on a satellite scene the side not facing the sun is very cold and the side that is facing the sun is very hot. But I doubt it can be used for that on earth, unless your talking about powering a few led's then yea I can see that happening.

[PerfectBlindness]

Where do you put the energy? I'd use it to power heaters that re-distribute the thermal state of the satellite, and shoot excess power into space as electromagnetic waves.

[timerider4]

I would love to have one of these, too bad they're so expensive.

[seth797]

That is ok for a desktop.

How big would it need to be to provide enough torque for locomotion or electricity generation?

[oisiaa]

Enormous. I have heard that it would take an engine the size of a standard 10,000 bushel grain bin to produce 100kw (~135hp).

[Dojan5]

More...

[roomoleum]

very nice

[Ferroscene]

the next time you try ice you should figure exactly how much electricity it takes to make the ice compared to exactly how much power the ice gives off, this might tell the combined efficiency of the freezer and the engine, any ideas?

[moonfly1]

could be a different matter for generation power at an artic research station though?

[v5dan]

I appreciate fine engineering, and that is utterly stunning, a work of art.

[adamzampino]

The key to success with these technologies is to combine them, as in series.

[Fihiextroya]

muy bueno, si señor. esto es crear energia y no lo que hacen los nuevos diseños comerciales..

[newphoenix84]

Steam punk at its finest!

[dorogol]

Yeah... everyone in the world now needs blocks of ice or heaters to make their engines run...

Not exactly efficient/smart, but it IS fun/interesting to watch. =)

[gyroscopes]

It does become "smart" when they are connected to the exhaust of boiler to generate small amounts of electricity.

[kinga303]

why not just run that off a few heat exchangers? apparently they can operate at greater than 100% efficiency

[gyroscopes]

Over 100% efficiency? hmm I doubt that.

[kinga303]

so did i, but apparently it's true.

hence why i said apparently :P

my knoledge of physics are rather limited but i'm trying to work on it as i wish to be a performance mechanic one day, and the key to performance is physics

[gyroscopes]

Can you provide some references to this.

[sentriclecub]

He meant you can get "free effeciency" by the waste heat. He meant you can get over 100% effeciency compared to just the effeciency of the lone substrate. You can get 110% of the original investment by getting a "free 10%". he's not aware of all the thermomechanical lingo, but I knew what he meant and I apologize for hiim. He is talking about increasing the productivity, but accidently said effeciency.

I am a science teacher, so these kids are using the wrong lingo, but let them learn conce

[gyroscopes]

Ah. From waste heat then yes I guess you can. That makes sense.

[DragonTamer2345]

wouldn't that be perpetral motion (sp)

[gyroscopes]

no it wouldn't

[nefty420]

it would be in cold climates no?

[gyroscopes]

no. anywhere.

[gluino]

Stirling engines can already achieves similar efficiency as photovoltaics and other ways of generating electricity from sunlight.

[Luthor65]

The difference in Temperature creates an imbalance and everything constantly tries to find equiliberium. The greater the differences the more energy it takes to reach eaqual terms.

[518schenectady]

could we get free power in the winter since ice is everywhere in the northern regions of the world?

[gyroscopes]

if works on a tempature difference. So you can get power in the summer or winter, provided you have another source of heat/cold.

[vycterio]

OMG !!! I LOVE PHYSICS

[colin340]

i like the "cranks" very nice how did you make the fly wheel there insane

[gyroscopes]

Its all done on CNC machines.

[gugegago]

i was just thinking, (JUST imagining) if we route the air from sahara or nearest desert to the cold places of the earth using a VERY EXPENSIVE tunnel or tube, could it be possible?!?!?

[Ferm3]

It would be easier instead to be in a hot place near the ocean. You could then use the depth of the ocean to move cool air to the device.

[wolih]

why would it run on ice?

[gyroscopes]

I suggest you look up stirling engines on the internet and do some research.

[punktish999]

just answer the cuestion...thanks!

[gyroscopes]

Well for those that can't be bothered it works on a temperature difference. The Air expands and contracts.

[hyperkid86]

couldn't you theoretically place these in a cold environment such as the arctic and generate an endless supply of power?

[gyroscopes]

why the arctic? they work on a tempature difference.

[fallingwater]

Stirlings run on heat difference. The ice works because the ambient temperature is higher. Go on the arctic and it'd run much better if you heated the engine, but it wouldn't run at all with ice.

[RaptorRyda91]

i dont get it? wut is this? perpetual motion?

[gyroscopes]

No its not. its run from a block of ice.

[septje]

Read up on the laws of thermo-dynamics. Its essentially working the way a generator works, except conceptually in reverse. As long as one side is warmer than the other, energy is being converted. There is no such thing as perpetual motion.

[branthony1151]

oooooooooooooooooooooooooooooo­ooooooooo!!!!!!!!!!! ok now i got it thats kewl

[Validole]

it uses temperature difference as its energy source.

[demondman50]

dude attach an alternator to a shaft at the top spinning thing and you got a really efficient engine, if it only runs on ice

[eatingjif]

im confused like the sort of ,wow am i really really stoned or is that t.v actually broken, tht sort of confuse but ill watch it 6 or 7 more times because im intruiged (i cant spell)

[rayunseitig]

Wow, another nice model. I bet this would work great in the arctic, where it may be cold on the ice but pretty hot in the sun.

[killercroc10]

cool

[thinkofafuckingname]

Who needs gas/oil anyway!!!!

[BluenoseModeler]

Great engine, did you build it yourself?

[gyroscopes]

no run a website which sells them.

[easternmafia]

is this useful in the practice? u must move the el. generator with it. free electrics?

[gyroscopes]

They are starting to be used in industry.

[pmarceau]

Is that what is used in nuclear submarines?

[demondman50]

nuclear submarines... the name is self explanatory they are nuclear they run off a nuclear generator

[gyroscopes]

I understand the confusion. Stirling engines are used on submarines. You need to convert the heat to mechanical movement. Nuclear ones use turbines but modern diesel submarines are using stirling engines.

[blackspace007]

Ummm maybe I should have checked the other videos.I actually thought my idea about alternative power use was original,lol. Well nice to see the idea being used, it's brilliant!

[SodiumCyanide]

I really like your videos! Stirling engines have always intrigued me and I agree that they are an underused technology.

[gmodesike]

love your videos..reminds me of the movie "time machine", but this is real and very cool!

[Killer16333]

so your saying that if we put on of those things on a hot plate like in my school, or one of those genertors in power plants, we would get more electricity from the same ammount of burning? THATS AMAZING, GLOBAL WARMING IS ENDING!!!!!!!!
