Just reading up on Solar Water Disinfection using PET bottles and the first thing that popped to mind was incorporating a Mylar space blanket in the mix. Ie, do everything else normally, but place the pet bottles in the sun on top of a mylar space blanket. Any excess space blanket can be angled to act as a reflector to get more sun into the general area of the PET bottles as well.
The way my rather rusty brain is working is: wouldn't any of the UV/IR that goes all the way through the bottles - be bounced back up and back into the bottles for another trip? Sort of the same principle as sun burning your eyes when on the snow/water/above the clouds due to the additional reflected sunlight? Am I overlooking something?
