Heat Engine aka Stirling Engine

[imaqtlolz]

if you made a sterling engine out of silver would it be called a sterling sterling engine?

Nice vid(and engine)! But concerning supressed: I read that the Swedish and Danish navies use stirling engines in their submarines due to their silence(the 'Gotland class' or something like that). Yours is also very nice and silent!

@ikwil There wouldnt be even 1 dirty coal fired power plant on the planet if this technology hadn't been suppressed. Instead the oceans are now so full of mercury from coal fired power plant pollution that people can't eat the fish without suffering Alzheimer's. Pregnant women can't eat the fish without damaging their child. Everything would run off sunlight or biomass. The present industry has so damaged the planet, we're in the middle of a mass extinction that hasn't been seen since dinosaurs.

nice ok man, I understand that the piston must be black, to absorb all wavelength of light. 5000****

How much work can it do (ie-Torque) and how much energy in heat was first put into it compared to the work done? This concept reminds me of the over unity magnetic generators but as with that nothing is really doing any work.

rocyahsoul, please view my latest comment to danielvincentkelley.

Ok, i see your not one for logic. You win, the layman beats the engineer that has been workin with engines for years. Do some research, and not on conspiracy theory websites either, which seems to be the place you are getting most of your info.

[danielvincentkelley]

WHAT!? Conspiracy Theory websites? I didn't read anywhere that the heat engine was suppressed by a conspiracy. That it has been suppressed is obvious. It's a clean renewable energy source, good for making electricity, yet it's in so very little use. The claim advanced by historians is that it's been suppressed by market forces and poor engineering, relegated to powering church organs and water pumps. Scribd, the one website I referred you to, is a catalogue of literature. ConspiraTheory sites?!

[danielvincentkelley]

That website I referred you to doesn't say anything about conspiracy. It directly refutted with a real world example, giving exact figures, the notion you advanced here, that the heat engine requires too much space, to generate enough watts to make it worth producing. The reality is facilities have already been constructed which power 300,000 homes and take up less land than would solar PVC or wind turbines. So neh.

[paulie1982]

Yes but those stirlings that are powering homes (i've seen the array) are advanced stirlings, they use either helium or nitrogen as the working gas. If you think the stirling is supressed i recommend that rather than sitting on the sidelines and shouting why not try to advance the stirling engine, i think you'll find that its more difficult than you think and you'll realise the stirlings problems. Are you aware that it was tried in automoblies in the 70s? Its not viable at this moment in time.

"Stirling Engine ST-5 Demo Running 5 HP".

As you can see this state of the art stirling engine produces 5 horsepower and takes up most of a garage. A 1000cc internal combustion 4 stroke petrol engine can produce 120 horsepower & takes up a fraction of the space that a 5hp stirling engine does. Suppressed my ass.

[rocyahsoul]

Minus the energy wasted drilling to the oil, shipping the oil, refining the oil... Your 120 horsepower engine works out to be an energy sink. Heat Engines are on the other end of the spectrum, they can produce energy, not eat it. We're talking about apples and oranges. Efficient transport would be accomplished by electric vehicle which might be fueled by battery charged by heat engine.

@rocyahsoul

great comments and video!

Do you know how many square foot an average garage is? That Stirling Engine doesn't even take up a tenth of the space of an average size garage. It's about 3 feet high, by 7 feet long, by 2 feet wide. It doesn't take up half the amount of space as a minivan, never mind half a garage.

[paulie1982]

You are just being facetious about the space thing, you get my point.

I agree with you 100% that crude oil based machinery is inefficient, wasteful & harmful to the environment but its the lesser of two evils, they're a long way better than the stirling for the purposes for which we need them. I love the stirling, its probably my favourite machine of all time, you'll see a small one i'm trying to make on my profile background. If i get it to work i'll send you a link to the vid.

[rocyahsoul]

Malarkey what you just sent : New York sized heat engine to power new york. There was a foundry at Dundee in Scotland that was powered strictly by heat engine, same as an educational facility in Georgia. Goto Scribd dott com. Search for Solar Stirling Engine Partnership. -- "Solar Stirling Engine... are the most highly concentrated... renewable energy technologies, leading all current renewable energy technology, PVC, and wind power generators in the use of space."

[paulie1982]

I agree with you that some technologies are suppressed but the stirling is not one of them. I'll set you a task - you build a stirling engine that outputs the same amount of horsepower as a 1 litre car engine and tell me how big it is, it would be half the size of your garage and weigh MORE than your car, there is no conspiracy, only false propaganda by conspiracy theorists.

[rocyahsoul]

Another thing, how you would "power" your car by solar stirling engine is to use it to spin a generator at home to keep batteries charged. Then you plug your vehicle in when you get home. The guy who made the Segue made a stirling heat engine electric car. The heat engine charges the battery locally with his setup. A combination of central and local electricity generation would probably best meet long distance and local travel needs. Anyhow, it's been done, proven, yet never mass produced.

[paulie1982]

Hi rocyahsoul,

I would like to know why you think the stirling engine is a suppressed technology?

The reason the stirling is not used more is because it outputs a very small amount of power for its size, even though it is very efficient. At 6.00 mins you stop the engine with your finger, do you know what would happen to your finger if you did that to a 2 stroke engine the same size as that stirling ^^^ = it would take your finger off.

[rocyahsoul]

That the Stirling Engine has been suppressed is obvious. 99.9% of Americans don't even know it exists. How many 9's do you suppose precede the percent sign to make that statement about the World Population? It's clean, to power it by sun light it's renewable. Those are exactly the technologies that have been suppressed. In recent times tech suppression has even taken the form of assassination. Usually though the financially dominant just buys the rights and buries them.

[paulie1982]

99.9% of americans don't know anything about anything, but then again thats the same with any society no matter where they are from.

Are you an engineer? Did you read my previous comment? Everyone knows that the stirling engine is the MOST EFFICIENT MACHINE EVER DESIGNED, but it has some major flaws. If you were to make a stirling engine that could power a city like new york it would be bigger than new york state. It is not surpessed, it has problems that need to be fixed before it is viable.
