There are many movements around the globe working to solve the growing burden of discarded plastics. Some new organizations like Vadxx are returning plastic to it’s prior state â€“ oil â€“ and thereby saving bottles from ending up in trash heaps. Some government entities have simply outlawed certain plastics in an effort to slow their production in the first place. One of the most surprising new movements, however, is to incorporate plastics as-is, in the construction of buildings. This past summer I saw a local radio station at La Prusia, just outside Granada, Nicaragua that used the soda bottles for sound insulation.
Diaz and the MyShelter Foundation, working with students from MIT, have created Isang Litrong Liwanag, or â€œLitre of Lightâ€ – a movement that is spreading the word about a source of solar light even more affordable thanÂ Stephen Katsaros’s new solar light bulb, albeit one that only works in the daytime.
The idea is quite simple â€“ what better way to lighten up a dark room than with a hole that lets the sun shine in? By filing that hole with a plug that keeps out the elements, but still lets in light. In this case, the bottle doesn’t just let light in, but it refracts it, spreading light more thoroughly across a room and, on a sunny day, works about as well as a 50 watt bulb. On a rainy day, well, you still have some light.
Surprisingly, this idea is already almost a decade old. Brazilian mechanic Alfredo Moser made his first bottle light in 2002 during a power outage in Sao Paulo. It took five years for this message to get out to the world on how to spread light to people without electricity, but now the idea has been taken up by news agencies, changemakers and people who are just looking to save money.
Surely there are others in the world who have thought of cutting a hole in their roof for light, but only Alfredo Moser will be remembered as brilliant for it. The story of this success, pushed most vehemently by Litre of Light, is an amazing one.
