DjuiinoStar Stirling Engine, Solid Metal Construction (CNC Machined): an Interesting Working Model That Will Accompany with You for Years! Unique Gift for Engineers

About this product

*★EASY OPERATION: Set this engine over a mug of BOILING water; wait for 20 seconds; give the flywheels a gently turn; it will be smooth-running quietly and slowly for around 20-30 minutes. Power piston goes with faint sounds when the flywheels is rotating, which even quieter than the tick tock sounds of your clock. This model needs a relatively high operating differential between the two panels (we will explain why in description), so taking BOILING WATER as heat source is a must.

*★UNIQUE AND GRACEFUL: Twin flywheels are totally symmetrical on both sides of the nicely curved arm and run simultaneously when you give them a gentle turn. Hollow-out parts cut into flower shape beautifies its appearance a lot. 4 aluminum alloy feet & 4 golden fasteners on the top panel truly give this silver engine a more eye-catching appearance. Special anodizing treatment ensures this engine shining for years. It will be a great ornament on your desk.

*★AN ENGINE WITH FINEST WORKMANSHIP & MATERIAL: Essential parts all made by SUJ2 bearing steel are of precision up to 0.002mm tolerance. Ultra high hardness alloy with high-precision size enables those parts to be wear-resistant and interact with each other smoothly. The bent rod is of high hardness after the heat treatment, strongly stable to keep 2 aluminum alloy flywheels perfectly in the right position. It’s designed to, and we do hope and believe it will, accompany you for years!

*★WIDE APPLICATIONS: It will be a great conversation starter for everyone around you; a cool desktop piece amazing your friends and colleagues; a great gadget to kill time when boring; a relaxing stress relief physics toy for people in the office; an impressive gift for your families, friends, especially for engineering/physics lovers. It can be used for teaching physics, great to display basic principles of a Stirling engine and to show the art of design.

*★FANTASTIC GIFT FOR EVERYONE: If you’re always stuck in a choice that prepares a unique gift for someone you love, this shinning engine could be a remarkable one impressing them, gorgeous and funny. Especially for those who owned a Stirling engine before, you should try this one and I guess you will not feel regretful. DjuiinoStar stand behind its products, buy with confidence!
