Introduction: "Stirling" Pan

Picture of "Stirling" Pan
A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. Or more specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. It is the inclusion of a regenerator that differentiates the Stirling engine from other closed cycle hot air engines.

Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.

I used this on hot pan.

Put a pan with oil on hot stove. Wait a few minutes then put it on cold bumpy place. That's all! :)

It is true that the motion comes from the heat, but... it is not the application of heat that is generating the kinetic motion. It is the residual heat bleeding off. An engine takes a heat source and turns it into kinetic energy. You have to move the pan back to the heat source to "recharge it?" and I don't see a regenerator. neither do I see a closed fluid system. That's like calling a wind-chime an engine. "Looks like we'll be plowing the back 40 acres again, get out the frying pan, hook it up to the disker and start plowing!!" lol

Hehe, lovely! I favorited it, it's very interesting, but some more explanation would be welcome regarding how the pan + surface geometry + placement actually results in the movement. (Is it only me, or the video indeed has no sound?) Also, how exactly this configuration is still a Stirling cycle, is not very straightforward to me. Thanks!

Hey!

This project looks awesome, but there isn't really enough documentation of you actually making it for a complete Step-by-Step Instructable. There are two things which you could do.

1) If you happen to have images of you making your project you can create some more steps with more complete instructions and then republish your Instructable.

2) If you don't have any more pictures of you working on your project, that's okay too. That just means that your project is better suited to be submitted as a Photo Instructable. (Photo Instructables are really good for showing off projects that only have a few photos.) All you need to do is move any photos and text you have to the Intro Step. Then just reply to this comment letting me know you are done and I can convert this Step by Step Instructable into a Photo Instructable!

Thanks for your submission and let me know if you have any questions along the way!

Hi craftclarity!

I moved all to the Intro Step.

Thanks for your help :)
