As posted in response to a friend on FB, the areas where this is targeted at are also very frequently lacking safe drinking water, and this would nicely tie in with the SODIS method of disinfection.
Simple, and kinda cool.

Plastic Bottles vs Translucent Corrugated Fiberglass or Plastic
Clever guy... kudos! However, just thinking that a translucent plastic roof would provide a LOT more light in those spaces, can be installed in a fraction of the time vs. cutting all those holes, and is probably cheaper than a tin roof, albeit a lot hotter. You can get translucent corrugated fiberglass or plastic roofing cheap.
"Light transmission - what can I expect from Clear, White and Green Corrugated roofing?
First, keep in mind that a sheet of clear Plexiglass (Plexiglas) acrylic sheet is perfectly clear and is rated at 92%.
You lose 4% from reflected light off the first (top) surface and another 4% off the bottom (inside) surface.
Polycarbonate is worse - 88% for 1/8" and much less for 1/2". Glass is less than 92%!
Now with fiberglass, you have the resin and then the fiberglass - even in clear panels, the strands of fiberglass will reflect back light. No way you can get 92% like Plexiglass. So:
CLEAR fiberglass panels allow 85-90% of visible light in.
WHITE fiberglass panels allow 70-75% of visible light in.
GREEN fiberglass panels allow 35-40% of visible light in.
Plastic panels will allow a bit more light in.

Dare I say it?......
BRILLIANT!!!
I was just thinking the same thing.
Change the filler from water to something that won't freeze and it would also work around here too.
Of course, by the time we did that, it would probably cost more than a 1x1' sheet corrugated, translucent fiberglass.
