This Engine is NOT What You Think - Solar Stirling Generator

  • 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.

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.

    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.

    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.

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.
