Watch this video, from EcoWatch. Very cool. Installing water-filled plastic bottles in the metal roofs of some of the poorest homes in the world provides interior lighting where there was none, and creates new possibilities for living and productivity. "This video, shot in the Philippines around the time of the initiative’s launch, shows how the bottles are made and the vast improvement it’s given residents, including some who said they simply slept or always spent their time outside because they couldn’t see inside their own homes." What a great use of discarded plastic!
