I am experimenting with 12"x12" fresnel lenses to make desalinators. I am 
seeking further information on distance to object ratios, as well as 
materials that can withstand such high heat. Also I was wondering if they 
could be "stacked" to increase output? Someonelse must have done some 
similar projects...where...who...?
