  • This is true. I did ...

    This is true. I did the math. 30' diameter = 760 square feet. The power from the sun is 130 watts per square foot in a sunny area. That gives you about 100 KW for that diameter. Sterling engine efficiencies are limited to about 30% so that's 30 KW.

  • Wow I can't believe ...

    Wow I can't believe I've never thought of a solar-powered sterling! That's a great idea. The world's record for most efficient solar system? I certainly hope that gets fully developed.

  • jkcwebs, Starting ...

    jkcwebs, Starting at 3:03 he says 30 foot diameter dish (9 meter) can produce 30 KW of electric power on sunny day.

    I'm the guy who likes to shoot down the crackpots and scammers with their perpetual motion machines and voodoo physics. But this is real, and it could be practical. Hydrogen under pressure has problems, but those are technical hurdles. Helium works too as do other gases. It's just that from a thermodynamic viewpoint hydrogen is really good.

  • Monocrystaline Si ...

    Monocrystaline Si solar cells run about 15 to 20% efficient. Stirling engine uses the Carnot cycle to convert heat to mechanical energy. The theoretical max efficiency of Carnot cycle for 1300 Kelvins hot & 300 Kelvins cold would be 77%. Of course the mechanics of the Stirling engine, inefficiencies of heat transfer, working gas, and other losses would drag that down. I don't know how to calculate those, but if we guess 60% then the figure of 3 or 4 times better fits.

  • Great concept, but ...

    Great concept, but at present, very impractical; how much torque do you think that thing generates... hardly any. I can only imagine the size of the parabola that would be needed to generate enough torque to power something like a refrigerator.

    And you could heat water ore some material and heat-isolate it as good as poslible, and then use that heat at night

    haven't seen the whole dvd set, but the hydrogen engine fundamentals vid is on youtube in 10 bits. very worthwhile. the series is in my favourites and playlists. watch it if you have any interest in hydrogen as a fuel.

  • You misspelled " ...

    You misspelled "stirling". The inventor of the engine was Rev. Robert Stirling, spelled with an 'i'.

  • actually Sterling ...

    actually Sterling engines run on any difference in temperature (as long as its big enough) so you might be able to use it at night, but you would have to stick one heat source in the ground (cause it's always a certain temperature; i think like, 50 something degrees) and the other cold source in the air (cause it gets cold at night.

    wow, this is awesome, keep us informed guys, also could you clarify the efficiency here? some numbers or spreadsheet would be much appreciated and link to your website pls..

    nah it's ok. given the bad first impression i'm not particularly confident he knows what he's talking about unfortunately, i wouldn't pay for the dvd or want you to goto any trouble.

    when/if you end up watching that chapter, i'm interested if you want to tell me about it (hope your PC can send messages by then)

    I cant seem to pull up my favorites or send a message to you directly on this pc, mabee I need IE 6 or something, but Im on dialup..I could copy..when I get the blank disks if interested.Unemployed at the moment so not at the top of the list,but glad to share.I bought them for like $100,which seemed absurd,but I was ignorant and wanted more truth before building something that would cost more and end up a paperweight..glad I did.

    that "myths and truths of H2 stirlings" chapter might be worth uploading ;)

    The H2 stirling in this video really caught my eye, i eventually tracked it down to STIRLINGSHOP DOT DE (if anyone's interested)

  • I will get back to ...

    I will get back to you on that once viewed.Whole thing is over 7 hours.plus the demonstration DVD. The metro in the background has a carbon fiber 5k psi tank for "H" and runs on that or 5-7% 'H' to gasoline or anything else that burns.Also runs on Turpines,which are waste matter mainly of citrus turned into a fuel via destructive distillation.The car can run on very poor octane gasoline,or moonshine with the 5-7% 'H'!

  • Yes, it is Roy ...

    Yes, it is Roy McCallaster and you can find him at knowledgepublications dotcom.That is assuming he is still alive, the guy in fiming is pretty damn smart as well,was an engineer for chrysler for 10 yrs.I agree with you,I look into as many types of energy I can.The DVDs are a touch expensive,bbut well laid out..I have the 3 that came with the MultiFueled engine pack.2 are classroom electrochemistry I havent watched yet,but it says on the contents myths and truths of H2 stirlings.

  • not an ass at all, ...

    not an ass at all, i greatly appreciate the discussion. Don't get me wrong, i think Stirlings are AWESOME (for the same reasons chaoszen said above). But they don't produce the efficiencies that Roy here is claiming - i'd like someone to prove me wrong i really would.

    Do you know Roy's full name?

  • By the way Roid, I ...

    By the way Roid, I wasn't trying to sound like an ass,I am just wanting to learn more as I hope everyone else here is.I dont expect anyone to take the word of someone they know nothing about,but I encourage you to look at some of his research.I have the DVD with this on it,andit is only a fragment of what is mentioned as the topic is converting ICEs to run on "H" cheap,also multifuels.Like,$25 cheap.

  • Roid, I know it was ...

    Roid, I know it was only 'Roys' statement, but you hear he says that the stirling is 3-4 X more efficient.If unfamilier with his work,he is one of the leading researchers in the field of energy,having converted ICEs' of all types to run on "H" since the mid 60s.He is a very credible and accurate person,not the mentality of a liar.

  • Are you saying that ...

    Are you saying that is a toy-type engine in the aluminum dome? Or do the toys work on the same principle, perhaps using helium instead..?I basically want to know if the design is similar as a hobbiest..I have lathes,machine tooling etc. Thanks

  • Note that the work ...

    Note that the work energy to make the PV is not clean,nor cheap.Another thing to think about is other waste heat energy aside from solar.Engineers (auto)use means of regenerative braking,sometimes to gain electicity in hybrids.I wonder why this is not applied from the massive heat from the ICE?Answers welcome.

  • "Perhaps, but these ...

    "Perhaps, but these are much, much cheaper."

    Solar thermal is only cheaper on a very large scale, where you have many, cheap, flat collectors all concentrating sunshine on a large tower used as the heat reservoir for a single massive engine.

    On the scale of the demonstrated unit PV totally clobbers this device.
