Solar bottle bulb for low-income homes: A Liter of Light
The ‘bottle light’ is simple and practically cost-free: by putting water and a bit of bleach into an empty bottle that is fixed to the roof

EXPLAIN YOUR IDEA
An idea I've already posted on the renewable energy challenge (https://challenges.openideo.com/challenge/renewable-energy/research/a-liter-of-light-solar-bottle-bulb-for-low-income-homes), that's worth to this one, too.
Very suitable for the realities in underserved communities and not costly to implement. Curiously, the idea started in Brazil during a blackout by the mechanician Alfredo Moser, when he improvised a lamp with a plastic bottle, bleach and water. The sunlight hits the top of the bottle and the refraction effect spreads throughout the environment. It spread around the world from the moment the philipine Illac Diaz saw on Aldredo's idea an opportunity for help low-income families in his country through My Shelter foundation.
Low-income families in communities with no electricity. This idea is very practical and simple to be implemented, already working in several developing countries like Brazil, Kenya, Phillipines, India, just to mention examples.
HOW DOES YOUR IDEA TAKE INTO ACCOUNT THE CONTEXT OF URBAN SLUMS AND CLIMATE CHANGE?
We're so familiar to have energy in our daily lives that we forget its value and importance in our routine. Just to list some benefits:
- possibility for children to study and do their homework on evening and at night;
- small stores and kiosks can keep open at night;
- provide safety in the streets, reduce the risk of crimes;
- families can have social gatherings after sun goes down;
- people can do income-generating activities after sun goes down.
It can also be combined with other sources like sunlight.
Yes, for one year or less
