Very nice! I like the parabolic reflector built on the engine.

[wyrrox]

The power of nuclear fusion!

[kowdie12]

like the coaxial piston set up

[LNMagic]

I like that as the engine speeds up it begins to sound like a plane. That must take a lot of power!

[ralph5656]

evidently twisted gentleman doesn't take his reading too seriously. There are real submarines that use stirling engines. The drawback is they are very expensive.

[bmovie67]

Power enough to heat the water for an steam engine? May be a good solution. 

[TwistedGentleman]

I think you guys are reading too deep into this. Stirling engines are basically model ships for technical minded people. They're charming toys, not free power solutions.

Arguing one way or the other is missing the point.

[sirtom68]

I have yet to see one of these that can produce enough force to do anything remotely useful. I just cant see that thing turning a generator.

[gyroscopes]

@sirtom68 Baxi have a heating system using a stirling engine (produces 1kw). Sunpower make 75w to 7.5kw for power generation (been selling them for sometime). One type of submarine use them for silent running power. cleanergyindustries also sell 9kw producing stirling engine.

[jeeze28]

@sirtom68 infact in arozona they started an experiment with a farm of these that generate 25kw each..

[SuperAlan74]

@sirtom68 Check out Infina. You can search it in You Tube or Google. They are not selling to private owners but they do have machines that will put out a significant amount of power. Cheers

[SilverCritter]

Could you power an air-conditioner with it?

[enerams]

@jetsamjetsam win

[WARIOT2210]

how much energy can it generate? Is it more effecient than solar cells?

[andreas2tv]

@WARIOT2210

i dont know, the some question i have, but i know that solar cell the by them selfs the can't generate AC power. This engine generate AC power that is an advantage.

[EGMAG]

Using the Solar Powered Stirling Engine, if you attatch copper wire turnings around the rotor in a magnetic field why can't a large version be used to generate free electricity?

[Dasmaster1]

@EGMAG Because its not effective enough especially not that way

[AliasUndercover]

Look up Stirling Engines on Wikipedia.

[UncleKennybobs]

Did that show all the light focused on the centre, or was that just an artefact of the video? It looked nice and hot!

[wilkes420]

@UncleKennybobs that purple streak of light is infared radiation (a form of light/heat waves that arent visable to human) that showed up because his camera doesnt have a i.r. screen built in it.... It was from the center because the curved disk focused all the light waves into the middle for colection

[ottgooroth]

great tech. could be used in all sorts of pump applications

[Ratysz]

This one's great! Actually gave me a hint on my next robot :)

[derekchoi2005]

sun power>>>K.E.>>>>eletric !!!

[treyflip3losthispass]

what kind of current do you get off of it

[knarfweasel]

its cool but some more info would be nice

[Mmkkw]

really cool!

[MrXstacey]

bravo, well done

[KasperDrengen]

it seems to me that it slows down at the end... a lot.. is that right?

[aznlove251misan]

the ultimate masterbation machine

[hornetpalooza]

In SI units power (P) is measured in watts, electric current (I) is measured in amperes and potential difference (V) is measured in volts.

Did I write that correctly now or will we have yet another correction? :)

[chaz706]

Nah. You're good.

[konatsukuonji]

That's pretty neat!

[julianito64]

100000000000000 volts

[bubbelmo]

Volt isnt a unit of Power, but of voltage

[helehole]

lol so pwned

[dman155]

In fact Volt. is the abbreviated for of Voltage, which is a measure of current.

[newbiehacker]

Amps (short for amperes) are what current is measured in, I think you'll find voltage is its own unit.

[shiftnizzle]

newbiehacker is quite correct. amperes is the standard measurement for electron flow rate (current), i.e. how many electrons pass a given point per second. voltage is the measurement of potential difference, i.e. the amount of "electrical pressure" exerted from the power source.

that being said, i love these things. horridly lossy as it were, but beautiful design nonetheless.

[Crus777]

I hear some of them are actually pretty effiecent!

[mediaman2003]

how hard it is to make this engine? where do you buy the stuff from and how much power does it gives?

[gnomietrout]

Ha ha ha ha ha!!!! The Sun, oh, you're killing me!

Gosh Dang that was funny gyroscopes, thanks for making an old guy laugh. I think he meant the applicable torque transfer of power to a device or direct function.....but your reply was great!

[stav009]

not what I meant, I meant that the ability of your engine to turn the suns rays into work seems miniscual.

[stav009]

where is the power?

[gyroscopes]

The sun.

[tamilmannan]

how much power can this produce?

[speedstakerguy]

lots of power

[JayCKat]

very little actually. Stirling Engines are efficient but low power engines.

[evilrobotstudios]

@gyroscopes how much power does ot put out?

[rjniscool]

@stav009 Are you 8 or is it just that your stupid?

[stav009]

@rjniscool

No, I believe you are the stupid one, At best this parabolic stirling could power a few LED lights. So not very impressive, very very small amount of useful energy produced. It is a nice toy, but you seem like a smart fellow, so maybe you will be able to figure out how to power the world with it.

[rjniscool]

@stav009 Yeah i get you,I dont bothor starting a conversation though,Anyways he just never knew where the power was coming from,Just a reply to make him a bit smarter :3

[criticaboutvids]

@stav009 SOLAR POWERED.

[14Greekboy14]

@stav009 fail

[semiliteratedgod]

why are these always so fucking noisy ?

[speedstakerguy]

the airplane in the sky.

[pccalhoun]

...You're stupid...

[unclearless]

Very nice, yet it very clearly is slowing down in the last seconds of the video. Is this able to run for minutes or longer on end? As I think many of us would watch a full ten minutes of it at that RPM just for fun, yet I am sure cloud coverage would effect the RPM's, but you must be able to find 10 min. on a sunny day sir. Great work!

[rcfinatic]

I think part of that noise is that airplane flying over-

[Yellow2011]

great idea, but too noisy for my garden

[Dojan5]

If you wear braces, we can plug you in and run you off solar power too :D

Seriously though, how do you make a person run on solar power?

[MistaKow]

Chlorophyll!

Umm... we all sorta run on solar power.

[Dojan5]

Chlorophyll, yeah, if we were plants :D

[WhichDoctor1]

well we do eat plants and animals that eat plants. so essentially we do all run off solar power.

BTW thats a nice little setup you got there

[Dojan5]

Indirectly yes. I've heard of people getting sick due to lack of sunlight, not sure though.

[justaguy08]

Yes, i heard you need sun to make some vitamins (ithink vitamin D)

[Dojan5]

Yepp. You do.

[mo1971fordcrew]

yer andr if you can make it go fastre rmp's itll do beter.

[TommeyLeeReed]

Use a fensen lens the output would be 10+ times the heat.

[HLSDK]

No, a fresnel lens would not make the putput larger than the input. It would allow the machine to capture more energy by focusing an area larger than a parabola, onto the parabola, and then onto whatever Mr Gyroscopes is using to collect the energy

[Oh861]

if you polish the coletor to a mirer shim an have it the coletor you well bost the speed of the engien

[SWINGREGORY]

GREAT

[vqdset]

search "Concentratore solare da parabola satellitare" an experiment of italian student in 2006.

[nustada]

Have you ever tried sticking some magnets on the wheels and setting a coil to measure power and efficiency for output.

I've seen Stirling Solar's idea, but I would like to see stuff like this on everyone's roof.

[Veritian]

wouldn't you get more heat if the there was blackness at the focal point? slick, otherwise.

[waragainstgreed]

rare do i see such energy conversion so direct.... excellent work.

[bccritters]

it is the heat you are utilising here correct? if so, then why not use a solar cooker type design instead? it is a simple black box with aluminum inside, covered by glass. they get hot enough to boil water on a sunny day.

[Nichen]

How many watts does it produce?

[edgarinv]

wow, i liked thiis one

[musingmumbler]

steampunk solar power! I like it.

[deauzie]

can i buy one

[lucifandalock]

i've never seen a solar panel like that before

[44R0Ndin]

not a panel, its a parabolic reflector like on a satelite dish, it collects and focuses the sunlight to put it on a tiny spot
