Megan's Stirling Engine

[adenubbila]

what is the gold metal thing called??

[KaylinJH]

i wish i could find a decent how to video when it comes to a sterling engine :( Id love to make one

[liljohnnotbigjohn]

/win :D  good job :D

[raguramangvignesh]

Beautiful one

[bkibbeeg]

I know it's old, but that is FABULOUS! Possibly the best coat hanger crankshaft I have ever seen. My friends call me McGyver, but I bow at your feet o great one.

[vekteius]

what's the brown stuff?

[cinndave]

Heh. It's got a piston rod connected to a connecting rod. Looks flimsy but it works fine. Nice to know that these stirling engines can work even if they're all crooked like that.

[kramedawg3114]

What is the balloon used for? How exactly is the displacer moved?

[helliviknow]

@kramedawg3114 the displacer would be moved up and down via the rod in the middle. The balloon is used in place of a tradition piston. it can be tricky to come up with a piston to fit an exact chambe size without being to snug or loose. The trick with these engines is to not have leaks. What you seeing is the ballon/piston inflating slightly pushing the rod up on the heat cycle, then pull back during the cool cycle.

[helliviknow]

@kramedawg3114 when the displacer moves up, the cool air from the top is forced to the bottom and warmed by the flame creating positive pressure pushing the piston/balloon up. when the displacers moves back down the warm air is forced to move up and then cools creating a vacuum and pulls back. This simply repeats

[akcessdenied]

thats a odd looking CD player...

[vengencefrom1979]

keep up the good work megan!

[TaNgLeD2121]

great work,... i know how much work goes into figuring out the propore ratios

[firedude201234]

the top rod and the cd are a bit unbalanced but great job:)

[rroberts383]

nice work ma'am

[Fawad70]

BUT WHY IN THE KITCHEN ? i DONT GET IT ?

[xXxHipHopMasterxXx]

nice one! =)

[BizarreAMV]

Heheh! Great work! Cheers ^^

[elositodelpan]

muy bueno

[arg13415]

whats all the red stuff all over it?

[usermanefer308]

i think it is EPOXY ¬¬

[cinndave]

@arg13415 Probably an epoxy or caulk. It won't work unless the inside is airtight.

[magicalmachines]

To see more about the Stirling engine check out my site, which has a detailed report on the subject

[magicalmachines]

If anyone wants to find out how these machines work check out my site

[tribbleva]

Almost two years and 100K+ hits... fabulous!

What is the red material you used to seal the top?

Why did it stop?

Have you built any more?

Fun! :-)

[suddibrit]

good work....

[holzpusher]

if we desperately wanted to know how long it ran, we could time it ourselves from the video.....but we did learn how to spell Stirling. very educational

[popupwool]

What's the heat source?

[mamccarthy]

a small candle below the engine

[smartstuff2buy]

the bananas are in there right now, thats powering it

[philleema]

This takes me back to our well engineered Stirling Engine during my Physics Degree. Only the one shown here works a lot better. Well done!

[derdudernan]

Very nice, overdub an explanation!!! :) Thanks for the video.

[pietilidie]

now all you need is a laser beam and you got yourself a cd player! LETS BOOGIE!

[johhnyboygomez]

hahahaha.. possibly the funniest post ive seen on youtube.

[13101988andoni]

hahahhhaha hoo man you made me cry haha really funny!!!hahah!!

[TheMonkeyBrothers]

how hav you heated it?

[EVVIE1608]

Megan,

Knowing nothing about Sirling engines, but having interest,(I have no sound ,long story)

I found your posting informative even With No

Sound!

[geoff390]

Are you speakers pluged in? hehe

[mungoesmad]

Any one can make a sterling engine if you throw enough money at it but it takes great skill to engineer one like this, why are you so suprised we are all looking at it, it's brilliant. Be proud!

[rjscott2007]

ingrediants= balloon(preferably green) a tall can, a CD (maybe your old hanson CD), a metl rody thingy O.o, and alot of bigRed chewing gum....

[eleanorroosevelt1]

looks like one of arthur ganson's contraptions.

[philoupaulo]

Et les Shadokcs pompaient, ils pompaient qans trêve !

Small and simplicity is so beautyfull !

Marvellous and funny !

Can you give an discription of the materials that you used? I need to build one too, it's a schoolproject. I hope you can help me out ;)

[fergawdsache]

Could you use this as an artificial heart

[cyborgtroy]

wtf? It's a heat engine / heat pump....

[dreamthinker79]

yea..makes it perfect, it would run perpetually off your body heat, obviously you wouldn't want to use this one in particular, but a sterling engine....you bet it could run a heart

[TheGreatDolanmite]

no, I don't think you can use it as an artificial heart, or use it to power an artificial heart cause inside the body there are no real temperature differences for it to run on... good idea though! : D

[rocketcane]

the heat makes the motor[spin] the motor doesnt make the heat

[muchogringo]

it can also be run as a heat pump/refrigerator if the piston and displacer are moved by outside mechanical work

[jasonguyperson]

it's amazing that a concept so simple really isn't widely known and used in the energy industry - applying solar energy as the heat source would e awesome! but i love your engine! it's cute!!

[leporellodemazamet]

greeeeeeeeeeeeaaaaaaaaaaaaaaat­t!!!

[Tomaz89]

stirling is written with i, not with e like shown on the poster in the background xD but your engine is nice, I also am building one at the moment, I'll write about one at school.

[Hindermore]

pwahahaha, that was awesome! Do-it-yourself engineering at its finest :p

[denominator7]

Great job Megan!! what is the source of heat (or cold) in your engine?? ahh ok a candle, I heard it mentioned... now I want to try and build one too!! I'm very impressed!! good job Megan I hope you get an A+. :)

[dietcoke3396]

coool ::)

[gairitea]

I KNOW HER! shes smart and such!

23,267 views?! internationally too! amazing!

[NEUMOBIKE]

Megan you are a very nice girl!!

well done!!

[gairitea]

megan rocks! its a year late, but I admit defeat and acknowledge ur superior engineering skills :-D

[TeslaFan9]

Fantastic - inspirational. It's really great to see someone can put a stirling engine together without having to work in a metal shop or own powertools. Nicely done!

[ncbookz]

megan how do you seal the piston? from air escaping?

[andragairdnah]

here, I'm totaly new to this type of thing. I was looking up Plumbing courses then got sidetracked by solar water heaters which can be used to power natural energy engines which took me here. I've seen a few tonight and for DIY style materials this is a top choice. I wonder tough how crucial the difference of angle is beteen the can and green diaphragm? d'ye see it's not 45 it's not 90. On yerself Megan!! Star of the stirlings.

[WeltbunkeR]

lol, I've seen some very professional designs here on Youtube, but this is the most beautifull one!!! Awesome!

[james998964]

lol

[Bazap2006]

Wow 4,750 views as of May 23 2007! Incredible...

[chrisj8072]

cool

[slugfodder]

brilliant, well done

[scottmetze]

Great Job!

[phoglite]

awesome!

[koenenbw]

well done!

[gmark1953]

Great Job Megan. Looks like we have a new mechanical engineer in the making.

[bgineat]

nice but one tip, I read the free plans on building a stirling engine on the net and the balloon should be a little tighter and just pop in and out but not stretch yours looks too loose. I saw you glued it on instead you can use a rubberband so you can adjust it for tension. not too tight or loose just pop in and out but not stretch. nice job there.

[Bazap2006]

Well done!

[gairitea]

i bow down to your greatness. it may not be fast as lightning, but 7 minutes....JEEZ WOMAN! nice job

[Bazap2006]

Great job, Megan!
