1. In 2011, the technology behind Liter of Light was designed and developed by students from the Massachusetts Institute of Technology (MIT) and is based on the concept of “Appropriate Technologies” – a concept to provide simple and easily replicable technologies to communities in need.[6][7]The students had the idea to build solar bottle bulbs when they were constructing a school classroom made out of recycled bottles in the Philippines and they noticed that the school could not afford to pay the electricity bills, even though the building was sustainable. They realized that the walls made with clear bottles let light in during the daytime, and began to experiment with ways to use recycled bottles to bring in light through the roof.
In less than a year since inception, over 200,000 bottle bulbs were installed in communities around the world. Liter of Light has a goal to light up 1 million homes by the end of 2015.[8]
2. The idea of using plastic bottles for daylight was first pioneered by Alfredo Moser from Brazil in 2002.[3] Using the technology as a social enterprise was first launched in the Philippines by Illac Diaz under the MyShelter Foundation in April 2011.[4] In order to help the idea to grow sustainably, the Foundation implemented a “local entrepreneur” business model, whereby bottle bulbs are put together and installed by locals who can in turn earn a small income for their work. Within months, one carpenter and one set of tools in one community in San Pedro, Laguna, expanded the organization to 15,000 solar bottle bulb installations in 20 cities and provinces around the Philippines and began to inspire local initiatives around the world.[5]MyShelter Foundation also established a training center that conducts workshops with youth, business companies, and other groups who are interested in volunteering their time to build lights in their communities.read more...

Materials for the Solar Bottle Light Bulb
1.) Fill the 1.5 liter clear soda bottle with filtered water, then add 3 tablespoons of liquid bleach and tightly seal the cap.
2.) Cut a hole the size of the bottle’s circumference in the roof sheet material and place the bottom part of the bottle leaving it exposed under the sunlight.
3.) Make hole on the roof of the house to firmly fix the solar bottle light bulb in place.
4.) Seal the roof with sealant to prevent any rainfall from entering the house. Light is produced when the water inside the bottle bulb refracts and spreads the light inside the house.
So far 643 solar bottle light bulbs have been installed and the goal is to reach a million in 2012.
3. MyShelter Foundation’s vision through “Isang Litrong Liwanag” (A Liter of Light) project is to brighten one million homes in the Philippines by 2012 with the help of various partners and volunteers.
Here at the Development Marketplace, we love innovative technologies like this: transformative, affordable, eco-friendly, and scalable.
