Fresnel Boiler Version 2
This version of the Fresnel boiler advanced from version 1. After doing some tests we found the focal point was roughly 104 centimeters. So this rig has a holder for an evacuated tube at roughly 104 centimeters. The rig is designed to allow the tube to move in/out of focus. This rig also pivots in 2 dimensions. It can both follow the daily movement of the sun and follow the seasonal movement of the sun.
