Illac Diaz with Al Gore [via Facebook] A Filipino social enterprise distributing do-it-yourself house lamps, lanterns, and streetlights to impoverished communities has won the prestigious 7th Zayed Future Energy Prize 2015. MyShelter Foundation’s A Liter of Light project won the world’s biggest award for renewable energy and sustainability in the Non-Profit Organization category for its ingenious solar bottle bulb which reuses empty plastic soda one-liter bottles, turning them into solar-powered light bulbs. Founder and Executive Director Illac Diaz of the A Liter of Light project leads his team in teaching communities how to manufacture and install the solar light bulbs, in the process collaborating with local governments to install 12,000 solar bottle bulbs, providing light for 10,000 homes in Manila and surrounding Philippine provinces. The technology is simple enough, developed by Diaz after coming across the original bottle light technology while studying alternative architecture and urban planning at the Massachusetts Institute of Technology (MIT). The repurposed plastic bottle is filled with bleached water, installed on the roof, and as sunlight is refracted through the water and coursed into the room, a solar-powered 55-watt bulb is lighted up. The night lights version uses a small solar panel, four LED lights, a simple circuit, a battery, some plastic tubing, and the plastic soda bottle. The resulting three-watt bulbs provide enough light to a 15 square meter area. The circuits are designed to automatically switch on and off when detecting the presence or absence of daylight.
