No, no, no, no

You're going to have a mess of motors or cabling for all that complex 2 axis tracking for each mirror. Use parabolic troughs parallel to ground like most systems. The trade off for a lot less tracking (only 1 axis for an entire row) is that you need glass insulation on the pipes. Troughs will also use less land (no spacing due to sideways shadows between mirrors). You need aluminum reflectors to get the parabolic shape, or maybe you can figure out how to use aluminized mylar (very cheap, very light, and more reflective than mirrors due to no 8% glass reflection loss). The problem is how to get them in the right shape without distortion. Zawy 16:31, 31 July 2011 (CEST)
