I will be joining the school science fair.
Does anyone knows how to build an simple stirling engine.
I had read some books about how to build a simple one, but even the most simple one requires some instruments which I can't get.

Hope someone can help me.

what's a stirling engine?

Maybe I do know what it is and how to bult it, just that I know the word in Spanish.

centaurwind;
The Stirling Engine is base on the principles of "Charles's Law". Several simple construction methods can be found on the internet and also on Ebay. Remember that at a science fair it is important to understand the principle of the presentation more than the eloquence of the display. Build one from tin cans.
Good luck;
