About the project Edit

The solar bottle is a technique that produces light with solar light. This technique uses any kind of plastic bottle (pop or mineral water, for example) filled with water and a little bleach that is passed through the roof of makeshift dwellings. In this way, refracting light produces a light whose intensity is comparable to a 50-watt bulb.

Here we are helping an eco-environmental solution emerge by collecting used bottles and reusing them to produce energy to ensure the foundation of sustainable development in a developing country.


In what ways is this project unique and creative? Edit

The specific nature of this innovation allows a large number of individuals to benefit from inexpensive light using an energy source that does not degrade the immediate environment. It also ensures balance in the ecosystem because it recycles solid plastic waste that is a better combination of developing a network of energy and matter exchange that allows life to be maintained and developed.

What is the social value of this project? Edit

This project inevitably provides people the opportunity to continue enjoying and pursuing everyday activities without worrying about the obstacles related to not having light. It also allows people in poor suburbs to save on their electricity bills. We have also seen a decrease in the production of CO2.

This project was welcomed by the United Nations and last December, the designer was invited to the Durban Summit.

What is the potential of this project to expand and develop? Edit

Invented by a Brazilian, the project was first used in Manila in the Philippines. The idea was then executed in several other countries.

What was the triggering factor of this project? Edit

The project was started by Alfredo Moser, a Brazilian engineer. He noticed that the favelas were designed with the same principle. Intertwining plates were built with a weak to light that often forced residents to wire electrical cables illegally and dangerously. This is when he came up with the idea to use water bottles to produce light and avoid water degradation. In time, simply adding a few drops of bleach was enough.

What is the business model of this project? Edit

It is an solidarity economy since the project, which requires very little to be realized, is profitable for everyone and functions according to a principle of equality for all people and in the spirit of non-profit.
