This subject is intended to calculate and size a solar parabola but also, probably more affordable and effective, a linear parabola (parabolinic concentrator).
The question is simple: find the focus in relation to the curvature and find the best curvature!
Example, I have a piece of flexible synthetic mirror of 0.5 * 1m, if I "curve" it in the direction of the width on X cm (X <50 cm) where will be placed the hearth?

You noticed, too? A cleat is not expensive. But if you want a mesh of 8 x 8, so 2 times 9 cleats, it is immediately think ...
So thinking, you think you have better buy a plywood plate, and cut thin strips parallel in, as a cleat. I think you're right!
