Circular Reflections

Today, one of my classmates, who teaches at Toledo Technology Academy, brought in his Stirling Engine to show us. It gathers and concentrates the sun's rays and the little doohickey in the center of the dish is the heat collector.  It uses the heat from the sun to run a motor on the back of the dish. It's only about two feet across and is mounted on what looks like a camera tripod.  Despite being just a small-scale model, it was pretty cool! I loved the reflections of the surrounding buildings in the dish.  I did crop out my classmates surrounding the dish to reduce distractions.
