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.
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.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
