Place this Stirling Engine on a cup of hot water / hot coffee & it may needs some time to start. The time is depends on the heat source given & is generally within 30 seconds to 2 minutes...
The engine won't start by itself, but given a little push in the proper direction (strong enough to coast the parts over for several cycles), the engine will take off and continue running on its own.
The top plate is made from acrylic & bottom plate from alumunum, therefore all the moving parts are visible.
