This video popped in my facebook newsfeed this morning. It's about this small impoverished village in San Pedro, Laguna where the houses are so closely packed together, light cannot even come in. It was dark so people mostly stayed outside their houses... until "Mang Demi Solar" arrived with the solution of using plastic bottles which would harness the power of solar light and project them inside the homes.
Think of it as recycled substitutes for electric powered light bulbs which can generate up to 55 watts. Watch the video and be inspired!
