Solar-powered Stirling engine design details

Saturday, December 24th, 2011

I've put together a video of the latest version of the LT-2 Stirling engine. Because this low-temperature engine has minimal output power I sometimes consider it more of an artwork than an engine. I often refer to it as the sculpture engine. What this engine lacks in power it makes ...

Improving solar power when the sun is low in the sky

Wednesday, December 7th, 2011

Tests on my solar-powered Stirling engine determine it will run with a solar incidence angle of up to 59 degrees, but I would like the engine to work up to 66 degrees incidence or 24 degrees above the horizon. This number is selected because that is the angle that would ...

Self-starting solar-powered Stirling engine

Wednesday, September 21st, 2011

This is a continuation of my Stirling engine development for a sculpture project that is solar powered. Because this engine needs to autonomously control its operation, it needs to self-start at the proper time. Here's a video of the engine with starter and controller. This engine is based on the ...
