Q: What’s full of empty calories, packed in disposable plastic, saves energy, helps Earth’s ecology, and improves the lives of the world’s poor?
A. Coca-Cola in 1.5 liter plastic bottles.
It’s the bottles, not the sugary stuff inside them. Fill the empty plastic container with water and a touch of bleach (to suppress growth of clouding algae). Punch a hole in the corrugated steel roof of your shanty, make a secure metal collar for the bottle and use it to fix the container halfway-in. halfway-out of the house. Seal with a bit of caulk to make it water-tight. The sun will now fill the dark interior of your dwelling with the light of a 55-watt lightbulb, without electricity.
This simple action, installation of a cost-effective “solar lightbulb” or skylight, could vastly improve the lives of billions of poor people in sun-swept favelas, shantytowns, and bidonvilles and scattered rural dwellings around the globe. Watch a coke-bottle lightbulb being made in the Philippines. You don’t have to understand the language to appreciate the significance of the change in people’s’ daily lives.
