There are projects that will literally light up our lives in every way, and shows it Liter of Light, an NGO dedicated to providing all the necessary instructions so that developing countries can access to a source of cheap and efficient lighting. The result: a few lampposts which are made from, among other things, with plastic bottles empty that at one time it contained some soda.
The simplicity of these lamps is impressive. 3 watt LED lamp is connected to a controller and a battery that is recharged with a small solar panel. And to protect the lamp, nothing better than these plastic bottles, something that makes the entire cost just $70 and that you will not need any infrastructure to operate autonomously. The result is – again – literally bright.
A vital project in developing countries
The founder of the project, the student of filipino MIT Illac Díaz, explained how the entire project was born of the discovery of the lamp Moser, a witty way to illuminate interior rooms with a bottle full of water located on the roofs of the houses. Diaz wanted to go further, and since in 2011 he returned to his country has achieved illuminating 28,000 homes only in Manila, with other many thousands more in countries across our globe.
This lighting system is also because it is one Open Source solution that is easily replicable and you also don’t need to especially expensive components. Liter of Light published educational videos on YouTube to help build these streetlights, whose integrated circuits can be produced with a simple marker.
One of the last great successes of this project has been in the neighborhood of St. Louis, in Bogota, home to 16,000 people and where basic services are almost non-existent. The lack of lighting in the streets produces numerous security problems, especially for women, who face sexual assault.
The Liter of Light project precisely helps to minimize those risks, and indeed the problems with the darkness are obvious according to a study by the United Nations in that indicated that 1,500 million people live practically without access to night lighting systems. In this same report reveals that 1,300 billion people still rely on kerosene lamps, that it produce toxic gases. Not to mention the benefits of such projects are in areas such as education or health care, something that shows that many big ideas demonstrate an enviable simplicity.
