Hot Air Stirling Engine Desktop Gadget

Witness the marvels of engineering and physics with this little Stirling engine that demonstrates conversion of heat into mechanical and electrical energy.

The desktop Sterling engine is ready to go once you take it out of the box and fill the lamp with 95% alcohol to heat the glass cylinder. After warming up for a few seconds the flywheel will spin a rapidly. It will also light up the color-changing LED bulb mounted on the little generator for extra gadget wow.

Kids will love seeing this thing in action, and might spark a thirst for science and engineering. Not just for kids though. This thing is cool to play with as adults too. If you’re looking for a neat gift for an engineer friend, they will love this thing too!
