Clean and Green ideas - Natural lighting with a Solar Bulb

From Brazil, to the Philippines (in any direction), we have very poor people around the world who cannot afford, or do not have access to, electric lights. They live in crowded, dark conditions, and need light. You have some very bright, enterprising locals heard about an idea. They are now in business bringing light where it didn’t exist, or was very expensive to provide. A soda bottle, water, and a bit of bleach (to stop algae) can provide an equivalent amount of light as a 50 watt light bulb naturally.
