Stirling Technology ST-5 running in Auroville, India

[@synapticaxon9303]

This is the largest, most powerful and most practical stirling engine I've ever seen.

[@_Redu]

This is the most silent Sterling engine that i have seen so far actually doing some useful work.

[@how2what4]

yup very quiet indeed

[@how2what4]

this one is quiet because it's bolted to a reenforced concrete floor, all the torque and shake it taken up by the mass of the earth other wise the power of the devise would roam on it's own

Nice to see this technology be put to practical use, not just put on a shelf as an ornament. That said, it doesn't quite sound like it doesn't need any maintenance. Surely it could benefit from a bit of oiling and adjustment, and possibly some bearing and hose replacement.

[@how2what4]

in this video it's not running at full power, if it did, the linkage system would easily break

[@evanriddle1614]

Yes, a Stirling that does work seems to be the size of a 30 gallon US barrel. Not a toy! I'd like to see more of them put to practical use.

[@SamMonkulas]

This invention crys out to all technology experts showing how simple can be energy generation. When this Engine can grind wheat on one side and make dough or rice grinding on the other side begs to prove of how much energy it can produce with such worn out conditions. ONLY IF SOME ONE WITH MONEY can take this tech to build a sophisticated model and give some data as to how much heat energy was used to produce how much power. Also notice that Heat energy came from a bunch of wood branches (lying Free nearby).

[@isacchris1]

That's is awesome and an extremely efficiently running setup!!

[@how2what4]

I took the video in 2001, I think the engine was installed in 1988 and I think it kept running all the way to 2010. A well designed and balanced Stirling engine can run for a long time with minim maintenance. I found this one in this Indian town www.auroville.org/

Wow! A industrial use of a stirling engine! It is pretty quiet. I've seen some quiet designs out there. Too bad they don't have it attached to a alternator or some thing that produces power. There is still a lot of kenetic energy from each rotation that could be used for other things. (Such as a alternator/electric motor.)

[@AgeofReason]

So how does this operate? Heating a fluid within a sealed system until the it gets excited enough to push through the system?

[@manobra2023]

Its the sterling cycle. Imagine that the air is like a fluid. It works by heating/expanding the air inside a chamber. There is a displacer, like a large loosely fitted piston, made out of something porous, light and fire proof. This moves back n forth making the air on the hot side expand as it also contracts on the colder sider, yea? This creates a blowing and sucking of the air with in. there is another, normal tight fitted piston or some kind of diaphragm on the cold side that pushes (power)a mechanism that makes the displacer plunge back n forth and turns the fly wheel. Its the momentum of the fly wheel that keeps the cycle going. so its a difference in temperature that makes this work. As the cool side slowly gets warmer the engine slows down requiring cooling. It can get quite complicated to manipulate this expansion and contraction but there are many examples of how this thermodynamic power can be harnessed.

[@ser7ser7i]

Thank you.

[@daviddavids2884]

some late info. this appears to be a horizontal beta config. the beta config has one drawback, it does not allow the degree of thermal isolation of the sides, that the other configs do. in the case of an htd stirling, engine operation should be optimized, for Speed. moving components should be as light as practical. high engine rpms should be Converted to (increased) torque potential, via the use of Reduction at the engine output; in other words, Mechanical Advantage (over the load). a Small radius drive pulley should be used. under load, engine speed should Not be too much reduced; say, ten to fifteen percent. at 5:31, small drive pulley not used. googletranslate

depends on where it is made, places which have a thriving cast iron industry could make it for a low cost. Places like Burma, India or Bangladesh.

On this model it’s air cooled but there were version designed with water cooling as well

[@how2what4]

on this one, the wood isn't being fed the way it was designed. With this one, the furnace is rolled away piled some wood into the furnace, start a fire, roll furnace back, hand-crank the blower until the engine took over. The original design had a hopper that could feed fuel sources like wood pellets or waste material from a farmers milling processes. Rice husks were a popular choice.

Is it a rhombic drive crank system.

[@how2what4]

it's not, the engine has to be fastened to a concrete base, if it had a rhombic drive it would be so well balanced it could be free standing. I think there was a desire to go in that direction with some engineers but the lack of funding in the 1980s for the project prevented this. The idea of this project started in the 1970's when the oil crisis was at its peak.

I was wondering about making Ultra Low Temperature Diferential Stirling Engines for houses. It shoud start at 0,1c, with 0,2MPa using Helium, 500 000 cc, with delta temparatures power shoud be: 1c-1,1kw, 2c-2,3kw, 4c-4,6kw, 8c-9,2kw, 10c-11,5kw . It Shoudnt be mutch expensive either, about 100 000cc(100L3!) for 1500$ !! Best Solution will be 1 000 000cc(1 000L)(12000$) 1m3 Double Boxer Engine (selfstarting) 3 cylinders 2displacers and one double-power piston . Great for heat pumps, Central Heating, geotermal, . First we need heat collectors for spring and summer , one headsink in glas on roof for high temp ( 50-100c) and we dig a well for low temps (under 10m constant 10celsius). For Winter Situation is diffriend because well(10c) is the heat source and the air is low temp. Or you can plug stirling between your heat source at home and heatsinks in it. Key is to have bufor because you can keep warm warter from solar collector or else over night to power your house continuesly. What do you think about idea, power and prices ?
