Bend flat mirrors
Instead of flat mirrors used bended plastic mirrors as per http://www.solarfire.org/tech/helios/helios.html. A square piece of plastic has cross sectional ribs glued from corner to corner in a X shape. It is glued at the center. Near the edges on the rib, a threaded bolt is screwed through to generate a curved parabola shape of of the square mirror. http://www.solarfire.org/tech/helios/helios.html removed the photos and explanation of how they micro adjust a plastic reflective covered mirror in parabola shape with four bolts and two ribs. The ribs are glued at the center of the plastic mirror with the 4 edges not glued, allowing the ribs to bend inwards at the edges as the 4 bolts are tightened. As time allows a picture of how this is done will be uploaded. The plastic mirror is covered with http://www.reflectechsolar.com/pricing.html - Reflective Material.
