Low Temperature Difference Stirling Engine Model Hot Water Drive Engine Physics Toy Gift

Different from the traditional low temperature stirling engine design, we made this stirling engine with a square base.

Selected high hardness bearing steel cylinder piston, not worry about the breakage and short life of the glass cylinder piston.

Using aluminum alloy panel and bottom plate, through engraving and milling by high-speed machining center and anodized treatment, this stirling engine model is also an artwork on your desk.
