I used the machine for knowledge. It works just fine. It produces energy like it is designed to do. The knowledge I gained is good enough to make a bigger one. I'll change the way it works for future reference.
Quartz glass will be better than metal when burning. Recommend
The second type of the 16 cylinders engine model looks better than metal type. Working great!
This nifty little working model is precision made of high-quality materials, with minimal assembly required. The clear glass cylinders allow a better understanding of the Stirling cycle. It also makes nice static display.
awesome engine once you figure out the quirkiness
