Is it possible to build a solar power plant using old CDs?
I read somewhere that if you cover the inside of a VW bug's roof with CDs, you'll have a reflector focusing enough solar energy to boil water in a reasonably sunny climate. I'm curious: How far can this be scaled up, with racks of CD mounted on heliostats blasting a dark vessel to create steam to drive a turbine?
Yes you can, but then the fact that the CD's are circular will waste reflecting area unless you cut square each CD and arrange them in the VW roof. By the way, the use of the VW's roof is because its shape is almost a perfect parabola and you can concentrate the sun rays in its focus. You may get the heating capacity per square feet of CD by building a prototype of this condenser and expose to solar radiation, measure the temperature and time it takes the water to boil, and rise the steam to superheat. You may use an enthalpy diff. such as to return saturated steam to the boiler to preheat the incoming water make-up. With the enthalpy diff value you will get BTU/H-Ft2, the rest is to apply this result to the design of the turbine, that depends of what do you want it to drive.
