Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit (LT001)

I got this for my very gadget driven husband and he loved it. He loves seeing how things work and this is a fun toy that he uses almost daily. You should definitely wipe the bottom of the device dry when you are done using it.

Exactamente como describe las especificaciones. Excelente artículo!!

Nice product, the side transparent portion makes me to understand the mechanism easily. I've tested it with a cigarette lighter, and excellent

I was amazed that it works down to a T difference of merely 25 ºC, so very efficient design. The Stirling engine is a bit squeaky, but this can be solved by *SPARSELY!!* applying Teflon oil (no real oil, but Teflon nanoparticles in emulsion; solvent evaporates, leaving a thin Teflon film on metal parts). It's a great gizmo to run; sad how few people know about the thermodynamics behind the cycle process. Makes me wonder what kids get taught at school nowadays.

値段的にも納得して購入しました。低温型は安全で幼児でもメカの観察ができてとても良いものです。
