A few years ago when I was trying to get my head around all this sun tracking stuff, I built this small model of a sun tracker that was intended to reflect the sun onto a fixed target.
It used a 24 hour mains driven timer with a mirror glued onto the top, via a 45 degree wooden block.
The 45 degree mirror angle was supposed to reflect the sun back down the axis of rotation.
The whole thing was tilted upwards at 38 degrees (Melbourne latitude) and pointed due north.
It would have worked perfectly in spring or autumn, but a detail I missed at the time, was that the angle of the wooden block needed to be changed with the season for perfect tracking.
It was an interesting experiment, and I did learn from it.
If you can reflect the sun continuously onto one point, it would then be possible to reflect it again with a second fixed mirror onto the final target.
The second fixed mirror would only be required if you had multiple trackers spaced apart (to prevent mutual shading) all directing sunlight onto the same target.
It was just a crazy idea that I had at the time, that I just had to try out.
It "almost" worked, and would have worked perfectly if I had known to make my mirror elevation adjustable on the face of the 24 hour timer, instead of rigidly fixing it at 45 degrees.
