Would it be possible to build a solar power plant using old CDs?
Would it be feasible to have racks to hold groups of CDs together connected to heliostats to reflect the sunlight over a large area into a black receptacle where water is heated into steam to power a turbine?
It seems to me the limiting factor here is the reflectivity of the CDs. I mean, it's not like there's a terrible shortage of discarded CDs, is there?
