Markets in Everything: Solar Coke Bottle Lights
Used plastic Coke bottles are now transforming the rural neighborhoods of Manila, Philippines. Homes there are often built so close to each other that they have no windows or natural light, but now affordable "solar Coke bottle lights" are being installed in roofs to provide an overhead "solar light bulb" inside the home. With electricity unaffordable or unavailable for many Philippine families, they used to have to work, do chores, and eat in near darkness. Now there is light, thanks to human ingenuity and the recycling of used plastic Coke bottles. Take a look.
