  • this was nice and clear

  • Wow

    But what the name of the programm ?

    

  • @thewaveboardtutori - I made this in Blender, a free 3D modelling and animation program.

    It was a little awkward because Blender didn't support procedural animations at the time, but I think with the latest version it would be pretty easy if I used the right Python bits.

  • Check out my engine, goes really well!!

  • fggre rfdr her

  • That's a good point:D I downloaded it:P But i think it's one of the best programs

  • Also, I just recently got AutoCad, so I might play around with a better-looking version of this next time I'm in Windows. Not to diss Blender, but it doesn't seem made for engineering animations.

  • Is autocad for 3d too?

    Thought it was for 2d only?

    Anyway, I was talking about a real heatpump, not a reversed stirling engine. A real heatpump nowadays have a COP of 3-4, that means 3 to 4 times as much heat out as electricity put in.

    I seriously belive that a common heatpump actually generates a higher temperature potential than the energy put in, but even if it dindn't, you could still use it as a source of electricity, by drawing energy from our average temperature.

  • Heat pumps move heat energy from a lower potential to a higher potential, but I think it's been thoroughly shown that they don't actually create enough energy to do anything.

    In order to run a Stirling Engine, you need high and low temperature sides. Ambient temperature is only one temperature, you would need a colder side to 'get energy from ambient air', to paraphrase what you're saying.

  • @cyborgtroy so the Ideal would be a side in the antarctic ocean and the second inside the earth, that would make a sun of our planet, uhuhuhuhuhuhuh,

    scientist joke !

  • Yeah, I dunno. AutoCad is weird.

    I need like a physics program. I am learning to use the irrlicht engine and Open Dynamics, so I might just make a demo program and then screen-capture it.

  • use solidworks its a little expensive but it works far more easier then autocad

  • I'm not a fan of paying for software, that's why all my videos are done in Blender.

    I'm not planning to make anymore YouTube videos, but they'll either be in Blender or OpenGL unless somebody can recommend a really good free CAD program that runs on Ubuntu.

  • Cyborgtroy, you are the thinking about the big thing aren't you ;)

    What does a heatpump do? It makes 3-5 times as much heat as the energy put into it.

    What does a stirling engine do? It convert heat or temperature gradinets into mechanical power.

    Then you could have used the power obtained in the shaft to drive the compressor. Are we on the same wavelenght here?

  • Sorry, I'm not on the 'free energy' wavelength. Stirling Engines are only maybe 70% maximum efficiency as heat engines and probably less as heat pumps.

    No, the big picture is setting realistic goals for renewable energy. Free energy is not happening with current science and nuclear, solar, and wind is close enough to be a serious solution.

  • nice video.I have just started today using blender and I want to make a stirling engine

    similair to yours any advice?

    and would you know of a useful guide or tutorial, please tell me.

    thx alot for posting.

  • Look up the Blender tutorials, and learn how to use the transformation hierarchy and the follow, point at, and restrict motion things [Forget what they're called, they share a box with subsurfacing IIRC]

    I use all those for this video. Ideally, I would have done it mathematically, but Blender doesn't make this easy so I faked it.

  • It was pretty complicated.

    I made the crankshaft basically a series of objects.

    The pistons were constrained to only move in one dimension.

    The connecting rods were parented to the parts of the crankshaft, and I used a constraint to make them point at the hinge-like object on the piston.

    I think the hinge then followed the connecting rod, or the piston or something.

    It was kinda complicated.

  • nice vid, how do you make things move together like that in blender?
