This amazing engine will run from just the heat of you hand. A true Stirling engine of the gamma type, the SciMod 375 has a regenerator built into the displacer piston. Based on the design of Dr. Senft, this is a low temperature difference Stirling engine. A few degrees difference in the temperature of the bottom and top plates is sufficient for the engine to run. Watch the SciMod 375 run on a hand, a cup of hot water, a cup of ice water, and even setting on snow at www.youtube.com.
Stirling engines are famous for their thermal efficiency and are being studied as a way to provide green energy. The regenerator makes the Stirling engine have the maximum possible theoretical energy efficiency.
Some model engines based on the Senft design are sold as Stirling engines but do not have a regenerator and are merely hot air engines with ordinary thermal efficiency. Although some of these so called Stirling engines will run off of the heat of a human hand, a true Stirling engine like the SciMod 375 is best for teaching about energy efficiency.
The SciMod 375 is designed for optimum performance and made from quality materials including brass, anodized aluminum, and fine ball bearings.
Besides its use in education, the SciMod 375 is a real attention getter in public and a fine conversation piece. Use it to fascinate your friends.
It is also a fine gift or executive toy.
