Gadget Freak Case #204: Self-Starting, Solar-Powered Stirling Engine
2/7/2012

< Previous   Image 2 of 6      Next >

Two requirements were implicit from the start: First, this heat engine is supposed to run all year when the sun is visible from the sculpture's location. Second, it needs to be able to start itself.

Very Good Engineering

Very nice, Doug.  I heard you had designed and built several Sterling engines.  You must have a nice machine shop.  How about a few photos?  Cheers. --Jon

Thanks, Doug. Fantastic answer. I was musing about what the artist could do with all of the extra power generated by the Sterling engine and then I recalled the efficiency of the Sterling is barely enough to keep itself in motion. I'm not sure what the artist will augment, but your creation is a fine piece of performance art as it is...  =]

This is a case where I agreed to design and build a functioning prototype engine and the artist could modify it artistically to do whatever he wanted. I explained that it wouldn't generate enough power to really do anything except run. The artist can do more interesting things with the colors, finishes, and some of the shapes, particularly the flywheel and displacer. I get a kick out of watching the utilitarian prototype quietly running. I'm curious to see what the artist comes up with for the finished sculpture too.

Good point, Naperlou. That's funny, and in many cases true.

Actually, Rob, considering some of what passes for art these days, the engine might be the most aesthetically appealing part of the display.

I would think  the ultimate need does matter to the engineer, Naperlou. The design solution should have the that need in mind, since there could be a varity of solutions based on that need.

At any rate, Doug Conner will weigh in on this question soon.

Beth, that's a great question.  I guess to the engineer it doesn't really matter.

Cool looking engine and the creator seems to have done a solid job engineering a solution that can work around temperature swings. What exactly did this stirling engine do in terms of running a scupture? It wasn't evident from the video.
