This fully assembled hot air twin flywheel stirling engine is as functional as it is beautiful. Each engine is carefully constructed of high quality CNC machined aluminum alloy and mounted on a wood laminate base. The engine is provided with a custom plastic carrying case with handle for transport and storage. The small footprint of this engine makes it ideal for classroom use.

Background & Concept
The Stirling engine is a high-efficiency heat engine invented by Reverend Robert Stirling of Scotland in 1816. Since its invention, there have been thousands of variations, all stemming from Stirling's original patent in the 1800's. The term hot air engine is a catch-all for any heat engine that uses the expansion and contraction of air under the influence of a temperature change to convert thermal energy into mechanical work. The engine is fired using the included denatured alcohol burner. Heat from the alcohol burner is applied to the end of an air-tight glass cylinder. The air in the cylinder is permanently sealed inside the engine. This fixed amount of air is heated and cooled, causing it to expand and contract, thus driving the piston. As the displacer moves up, the air in the cylinder moves down to the hot side, so the air pressure inside the cylinder increases, causing it to push up on the piston. Alternatively, as the displacer moves down, the air in the cylinder moves up to the cool side, causing the pressure inside the cylinder to decrease, and pulling the piston down. This process repeats over and over again, setting the wheel in motion.

5 of 5 Twin Flywheel Stirling Engine w/ Case June 14, 2015
Reviewer: Wallace Garner from Big Spring, TX United States  
Very satisfied with the engine. It was packed in an excellent manner and ran right out of the box.  I did have to think for a minute about how to get the wick through the hole but took a paper clip, spread the clip and ran the clip through the hole.  I put the wick in the "U" shaped clip part and pulled the wick through the hole. Worked like a champ.  Thank you for providing such an interesting engine.

5 of 5 Stirling Engine November 24, 2014
Reviewer: G. Phillips from CT  
It's a great novelty, and enough fun that I bought three more for my grandkids.  What was best was the personal support of the sci-supply staff re some related questions.

4 of 5 Stirling Engine July 28, 2014
Reviewer: *** from ASHLAND, OR United States  
Nice "EyeCatcher" - BUT: The BASE is too small (engine parts are overlapping) and it is cheap looking out of fake wood w. plastic cover. A contrast to the nice and well done aluminum engine. I made my own base with aluminum cover and ply wood to match the design of the engine. Another suggestion: The LID OF THE BURNER should have a rim overlapping the pot, because it is hard to open for refill after use.
