DjuiinoStar Hot Air Stirling Engine, Solid Metal Construction, Electricity Generator (DHA-BG-405)

Product Description

Driven by the little lamp, this engine will rotate at speed around 2200-2400 RPM. Kinetic energy generated by energy exchange will be transmitted to the generator and then light up the bulb on it.

Our customers are satisfied with its strongly stable structure and exquisite body. It's mainly constructed by metal which ensures its stability while working; main parts are all processed by high-precision CNC router/laser cutter to ensure its performance; special treatment was made to make it looks brighter and smoother; use customized thickened quartz glass cylinder to strengthen its robustness. A great desktop toy, TONS OF FUN!

It's also a perfect teaching tool demonstrating the process of energy exchange: the hot air in the sealed cylinder enables glass piston to move continuously, and flywheel will spin at the same time; periodical air expansion and contraction makes heat energy converted to mechanical energy... Kids will be excited and curious about why. This will enlighten them to explore the world.

This is simply a piece of art. If you're hesitating about choosing which one to him/her as their first engine, try this one. You'll not feel regretful on your decision.>
