About 5 years ago and inventor figured out how to build a solar concentrator that doesn’t need to follow the sun or need to be adjusted. It works well as a solar Water Heater and could also be used to heat your home in the winter. The average solar dish or solar parabolic needs to be aligned with the sun every 5 minutes or the focus is not on target. Here are a few of the Pic’s he shared.
Works in summer and winter, You A Line East to West and it dose the rest. In my design I would have 8 to 10 Absorption tubes on the collector to maximize the Heat Transfer. Then I would have the heat directed to a Stirling Engine or an array of Peltier Units to convert the heat to a usable energy.
In fig 2 it shows the suns rays hitting the Reflector from morning to midDay from angles of 10° to 60° and where the focus will be at those angels. I guess now you would understand Why i would have 8 to 10 Absorption Tubes. Hope this info helps you to build a cleaner Energy Resource.http://www.rexresearch.com/lightfoot/lightfoot.htm
