Stirling Engine ROBINSON TYPE Education Science toys Learning & Education Toys

The Robinson's displacer moves vertically and the power piston move horizontally. This 90' arrangement makes for a very compact size. In fact, the power piston connecting rod weaves its way through the displacer linkage. The top plate is made from acrylic , therefore all the moving parts are visible. Place this Robison 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.
