  This dude hasn't told us the nitty-gritty of how it works. But it's a good science project.

  I forgot to mention the link. That guy has explained how to do it on a forum in russian -

  I used google chrome translate feature and the instructions and images made it easy to understand.

  Mechanical Engineers might be able to provide insights into this. What can be the applications of this?

  The working is nearly similar to the IC engine.
  
  there is a cylinder with a piston, and when this piston is heated, the air within it expands and pushes the piston forward which causes the crankshaft to rotate.
  
  the rotation of the crankshaft continues and it in turn pushes the piston down, which again compresses the hot air in it, and again the piston is pushed up due to the extra heat added to the air and the cycle continues.
  
  As for its application, well this is just another prime mover and can be used to drive any machinery, if it can provide that torque, which the latter would require for its normal operation.

  How Stirling engines work.

  Questions that I have:
  
  1. Is it vital to have that ninety degree offset between the sponge-rod and the piston-rod?
  
  2. Could you replace the sponge with something like, another sized-down tin lid?
  
  3. If the piston and the membrane were totally removed, would it still work?

  2. The sponge actually is acting like a boot, which is preventing the hot air from escaping. It can be replaced with anything as long as it is light and flexible.
  
  3. no it wouldn't work , because those are the vital parts of this engine.

  well, how?

  well, how?

  very simple !
  
  Take any I.C engine and remove its piston and connecting rod , will it work ?

  Hm, maybe I should have said the piston that's on the membrane; not the sponge. My mistake.
