Really nice work George, thanks for sharing. Gives me some ideas.
George Plhak seems to be a tinkerer of the best kind. His low-cost approach to a sun tracker / heliostat is truly innovative. Regardless if the parabolic mirror set-up is any more efficient than the flat panel version, his single axis tracker is the real genius here...
Your detailed descriptions are the best I have found so far.
Your enthusiasm is an inspiration.
That's a great setup :-)
I appreciate your sharing of information.
this is by far the smartest home made idea i have ever seen good job go on
