Here are two updates on projects built by readers of my book
How to Build a Tracking Parabolic Solar Collector.
From Andrew Gray in Texas:
Andrew came up with a novel way to swing his array both N-S and E-W and added computer control. He is heating domestic hot water so uses insulated collector tubes.
He has a series of videos about his project posted on Youtube and you can also read more here.
From Bruce Snyder in Florida:
Bruce heats a hot tub so he is able to use uninsulated collector tubes. He writes "It actually produces WAY TOO MUCH heat in the spring and summer".
As always, comments are welcome.
