It's cliche, but the social enterprise, A Liter of Light, is really a bright idea.

A Liter of Light is a sustainable lighting project that uses the eco-friendly "Solar Bottle Bulb" and science to bring light into the homes of communities nationwide. The Solar Bottle Bulb is the brain child of Massachusetts Institute of Technology students and is basically a plastic bottle filled with water (and bleach to prevent algae growth) that's installed in a roof. Refracting (bending that amplifies) sunlight, a single Solar Bottle Bulb, can provide the equivalent of up to 55 watts of light. For comparison's sake, many standard incandescent light bulbs in your home are 60 watts.

For more information, you can watch a short video clip of the project in action below, or check out the project's website.
