This Engine is NOT What You Think - Solar Stirling Generator
Вставка
- Опубліковано 2 кві 2024
- The Stirling Engine Generator is a sealed high efficiency “heat engine” that is driven by the radiant energy supplied from the sun or any other source of external heat. Invented by Robert Stirling, the Stirling cycle engine is a type of solar engine, or sun motor, which operates using the principal of thermodynamics alternating between the hot and cold temperature cycles of a working gas.
And who wouldn't want to hear that all day???
Those are poorly made toys. You can get these to be very, very silent.
Definitely less annoying than the narrator's voice.
True but it can help a lot of people with little to no access to electricity.
@@lyteyearz5810 I do realize that.
Sounds like a gasoline power generator but the fuel is sunlight.
Technically, any gasoline engine is powered by the sun, with extra steps 😂
@@asiburger yeah like a lot of extra steps
@@asiburger you could say that you're solar powered with the same logic.
Well, not really. It's an external combustion engine...
Its more appropriate to say it's a fusion driven heat engine.
ever since i found out about Stirling engine i wondered why no one thought about combining it with solar power. glad people did
It’s very inefficient, much worse then the crap solar we have, grew up off grid & lived more then half my 57 years off grid, the best possible is hydro, then wind which is crap, then solar, which is expensive crap, you can do wind with a blade, electronic gate, old alternator & a inverter but finding endangered/protected bird parts all over the yard can be EXTREMELY expensive indeed, their is no substitute for petro, period

Instead of sticking a big mirror on it, it wouldn't be hard to power it with the waste heat from an ac or a fridge, just a matter of correctly hooking it up
@@alexnorth2452 it's done on some submarines I can't remember from which nation. they have a dual power system, one of which is a massive stirling engine that uses the heat waste of the other engine.

The awesome thing is this is actually cheap as hell to make compared to solar panels
Also, produces more energy than it takes to initially make, unlike solar panels.
It costs way more per kW and breaks down faster. Get your facts straight.
@@michaelbuckersI’m just wondering what the point of these things would be aside from time keeping. Or if you’re near an observatory telescope, and use the positioning data to make sure you don’t aim the telescope to face the sun, or with more calculations, into the path of the sun.
I’d imagine that’d probably destroy the instrumentation inside the telescope.
@@CyberneticKinesis Concentrated solar power is a thing, but this here is just someone's toy project. Real installations that use sunlight for heat have giant arrays of moving flat mirrors that focus the sun on the peak of a tower, which runs liquid sodium heater or water boiler. For power generation purposes, it tends to be woefully inefficient compared to photovoltaic panels, due to the same amount of power produced but order of magnitude greater cost. But if you just need heat, not electric power, then these work very well.
@@gabrielclark1425 actually today's pv systems make enough energy in about 1 year to equal what it takes to make them. A couple weeks if things film pv.
Ideal for charging your phone
The cost is in the maintenance.
Jeez, that's gotta be a LOUD machine.
Do a video on solar vacuum tubes. Basically they are a clesr tube that is insulated with a vacuum that heats a fluid. Then that fluid is converted into electricity or usually for hot water/heating. I think it converts it into steam when making electricty yet I am not sure.
I just learned about them. Not sure what the benefit is over regular solar panels. I guess it works better in colder water.
We need to make better thermophotovoltaics damn it.
I will look into it, thanks for the info! I did not know they worked in sub zero temps, very interesting.
Never saw it, but we apparently had a facility here in AZ that had a bunch of these. After it was built and operated for some time, it was shut down and all the parts were sold off.
New things to walk past in your solar punk city scape
Feels like robot ducks
I read about some company trying to make sterling powered solar generators in the mid 90s. I think they were trying to make something that that had the magnet in the piston and wire coils around the cylinder, so there was no separate generator, just the “engine” moving parts.
I assume it wasn’t viable, since I never heard any more about it. Shame.
That would be interesting, at smaller scale this would be neat to have.
Free-piston sterling engine.
There have been many, still are some being developed.
Mostly they last until they move into production and sales then they go bankrupt.
Even when PV was 7 or 8 dollars per watt it was less expensive and more reliable then the stirling engines.
Isn’t there something that could be done to help turn that sound energy into more power? Seems like some lube or polishing could help
I don’t know, maybe. I didn’t have the volume up, but aren’t Stirling engines supposed to be really quite? (That’s what I heard) I have a small model that seems pretty quiet, except for vibrating so hard it scoots across the table.😅
Sound to energy not worth it. Consider hiw much racket a tiny cricket makes spending fractions of a milliwatt the entire night, then reverse that. You needs a huge boom to make a fraction of a watt.
@@davidaustin6962 ?? Stirring engines run on heat though?
@@I-am-that-guy132 yes
Yes; that’s exactly what a passive microphone does.
Probably also wears out faster
Lovely
Solar farms already do better with reflector arrays pointed at a tower that heats water to turn a turbine. They do have a habit of frying birds though
At least it is considerate enough to stop making you deaf once the sun goes down so you can sleep.
Awesome.
Also, replace the engine with multijunction pv at 35% efficiency. Normal pv is at 20% efficiency. Now do your math.
The possibility’s are mind numbing . Another example of a solution that was right over our heads the whole time
Real cool 😎
Problem is there are no way to contact autor. How much such system cost? Their are many places where is no electric piper supply.
Bet you could make a pretty damn good one using a fresnel lense. 😊
Sounds like big petroleum telling us it is too expensive to use when it clearly utilizes almost nothing by comparison to petrol. Given time and research it would become cheaper, more efficient, and eventually commonplace.
Lasts for 100 years if well maintained. Pv lasts 25 at best. Now do your math.
It's the heat from the sunlight, not absorbing sunlight to generate electricity.
These need to be everywhere.
They were.
@@lifeunderthemicwhere and when?
google+sterling engine= old news and the reason schools suck@@kx7500
Focus jet stream on a steam turbine tube stack. Pump and rotor motion
Actually hydrogen fuel is the next big thing after fossil fuels.
Not solar.
As good as this is a solar panel only needs cleaning while this needs proper maintenance.
I was expecting an Eastern European accent…
I have my doubts.
Needs more rpm
This system can be refined. You have made at least one mistake so there is a major flaw which is due to not refining the Sterling engine thus your restance losses are 50-60% worse than they could be. E for effort since this has potential but you stopped too soon in the design and needs more thought. Dont give up tho..
Seriously... pick a pitch & speed and stick with it!
Audio. a loudness..
Mars or Moon generator
Yet solar cells are more efficient at any scale...
That wont even charge a cell phone. Its just a wet fart sound making device. Waste of space get real
I've heard of something called A Step up Transformer, have you?
It's not very efficient, If you put that type of engine under load it becomes far less efficient. Also solar power isn't that powerful. I was tech channels like these would talk about nuclear power, since it's a hundreds of times more powerful
Where is it more expensive, huh? I call BS on that. You get more BANG for your buck for the same are than a gay PV cell. Which means you need less area for the same Wattage that you try to achieve. Or more Wattage for the same are. And less prone to Hail damage and less down time while doing maintainance 😂and the best in the end you can build Stirling engine out of literally scrap from scratch, do that with your gay PV cell proof me wrong pal! Man what BS you are talking 😂🤣
Typical photovoltaic solar panels operate at about 15% efficiency. To match that with a heat engine running at 2/3 of the Carnot efficiency, you'd need the "hot side" of your engine running at 115°C.
The problem is, you can't get a container of water that hot just by putting it out in the sun. Even in a vacuum-sealed black-painted solar thermal collector, when you get up to these temperatures, the amount of infrared light radiated away from the hot collector equals the amount of sunlight coming in, so very little or no heat is left to sent to the engine.
To get up to an efficiency that beats photovoltaics (& I'm assuming you are talking about something bigger than a 20w tinker toy that actually does something), you'd need to dramatically increase the ratio of solar absorbing area to infrared-emitting area, which means lenses or mirrrors to capture and concentrate sunlight. These devices would have to move to track the sun... then you need to isolate to prevent heat loss.
So now you're looking at running a engine with a generator that has higher maintenance, in a system with boiling water that requires isolation, with a complicated parabolic optical tracking system on the roof(good luck with this particular component) , not to mention economies of scale which work against you.
Of course it's more expensive, that's why you don't SSE everywhere..it's vaporware without on site AM that defies materials/manufacturing. It's a UA-cam short so I can't fit in 5 minutes of details (& I don't even like solar cells for local power generation). Don't get me wrong, the SSE has good footprint and is nice to see running, I would be the first to like your video on a homemade one but it's not practical at this moment & capitalism proves that.
