Ok, In my mind this works, but I don't have the skills to prove whether or not it would actually work. I know that I will get a cold side and a hot side, I'm just trying to put some numbers to the idea and have someone give me a crash couse in advanced thermodynamics.

I would like to understand the thermodynamics of an Alpha Stirling Engine. It would consist of equal sized cylinders. I was thinking small, as i want to build this eventually. So, 1.5 inch diameter cylinders 2.5 to 3 inches of piston travel, all gas sealed. Connected with a tube with copper mesh filling for the Regenerator. The two cylinders will be at a 45 degree angle to each other. The working gas would be Hydrogen or Helium. Since the "system" would be enclosed I guess you could keep the pressure at just about whatever.

Next, I want to apply energy in the form of an electric motor to the system. I'm not sure on the motor or the required energy at all on this. I know that I want the system to run off of a 12 volt dc power supply.

What I'm really trying to figure out at this stage is what will be the temperature of the cold side and the hot side. Once I know that then I can begin asking the next round of calculations.

About the only thing that is certain in the whole equation is that I would prefer that the size was small and uses 12 vdc, and the cylinders have to be in 45 degree angles. Cylinder size, working gas, motor and so on is really up for discussion/suggestion.

Based on the FPSM from Global Cooling/Twinbird that can be seen on YouTube they were able to get the head of the cylinder to -100 degrees C. But that's with a gamma/beta Stirling, i'm wondering kind of numbers you would get from an Alpha Stirling and what kind of electric motor would I need to find. For instance would a used hard drive motor provide enough energy/rpm/torque to work?

And trust me this will get more difficult if you aren't feeling challenged yet. Eventually it's going to be an enclosed space cooler.

Thanks,

Did I not explain the question in the right way? Do I need to be more specific? Do I need to provide links to the equations that I'm not sure how to solve? Do I need to talk more about the final goal? Do I need to be more controversial so that I can get a response to the post? Maybe about how in the end the device will be able to bend light and open the world to an alternate reality and stop time (none of which is the case but hopefully you get my sarcasm here)?

Just wondering?

No, you just need to phrase your post a bit more clearly...
