Recommendations

Slant the glass along the shorter side of the still
Water droplets fall back into the basin as the water runs down the glass. A shorter length for the water to travel should allow for more water collection.
Do not use RAINX or any other type of coating
Works too well, the water droplets do not make it down the glass. Also, raised concerns if the water was going to be used for drinking.
Buy Stainless Steel Bolts and Nuts
Make sure that the bolts are stainless steel and not zinc plated. The bolts rust VERY quickly, and the stainless steel bolts in the shop did not work.
Do not use 2 inch Copper Tubing for the CPC
The 2in copper tubing is much more expensive and takes a lot of water to fill the system. Smaller CPC tubing will be less expensive and more troughs could be used to gain the same energy output.
Find a different adhesive for Mylar on CPC
Current adhesive seams to have peeled away from the foam after exposed to heat. Finding an adhesive that does not eat the foam and withstands the heat would be ideal.
Change material for sides of Solar Still
As the water condenses on the sides it defeats the purpose of the transparent acrylic material. Choosing a material that is not transparent with better insulating properties could increase Solar Still efficiency.
