The Stirling engine is a heat engine invented by Robert Stirling in 1816. It differs from the internal combustion engine because the fuel burns outside the engine, making it much easier to manufacture. There are Stirling engines that run from the heat of your hands, although they are a little harder to build. The Stirling engine would be a good addition to any collection of those who like to make things with their hands.
The basic principle of Stirling engine is to constantly alternated heating and cooling of the working fluid in a closed cylinder. Usually as the working fluid is the air, but also uses hydrogen and helium. In some experimental samples were tested freons, nitrogen dioxide, liquefied propane-butane and water. In the latter case, the water remains in the liquid state in all portions of the thermodynamic cycle. Feature of Stirling with the liquid working fluid is small size, high power density and high operating pressure. There is also Stirling with two-phase working fluid. It is also characterized by high power density, high working pressure.
The Assembly of the Stirling engine with your hands(in the original language)
You need to build the Stirling engine in the present embodiment:
3 X Coke cans
1 X Balloon
2 X Spoke nipples
4 X 5A Electrical terminal blocks
Fine steel wire wool
1mm steel wire (about 30cm)
Thick (1.6 mm) Copper wire or 1.6 mm – 2mm steel wire
Plastic Drinks bottle cap.
1cm length of 20mm Dowel rod (you could carve this as you only need a tiny amount!)
30cm of Electrical wire (we want the outer insulation, so 3 core mains will be fine!)
Fishing line about 30cm long
Small scrap of inner tube rubber about 2cm square.
Small weights for balancing (5p 2p nickel etc)
A Lyles syrup tin or other tin for the firebox
Red temperature resistant silicone
Tuna can for a water Jacket
