STIRLING ENGINE OF HIGH PERFORMANCE: compared with traditional engines this one runs smoother and is stabler: use self-lubricated graphite power piston(less friction & unbreakable); stainless steel string as connecting rod between the crank on the flywheel and the piston(less friction); two little magnets on the power piston and displacer interact with each other as connecting rod to eliminate mechanical friction while simplifying the structure in a graceful way. A FANCY DESKTOP TOY: This stirling engine runs rapidly and quitely when placed on a mug of hot coffee. In addition we use better materials with special surface treatments to make it look prettier and have a higher performance: stainless steel base with mirror finish is rust-resistant; polished standing rod made of aluminum alloy has a smoother & brighter surface sturdy enough to stand on the base; clear acrylic flywheel make the whole engine has a more aesthetic appearance!
