Let There Be Light

Sometimes, solving some of the biggest problems involve the simplest of ideas. At least, that was the case in the Philippines; where a bottled liter of water with a few teaspoons of bleach is proving to be a successful recipe for dwellers in light-deprived slums. The simple technology is spreading sunlight in places where it has never been, and saving residents money at the same time.

Just another reminder that the biggest change often involves dreaming big and doing small.
