As is commonly known worldwide, there are two types of lighting, natural and artificial. Natural lighting is sourced from the sun therefore is free compared to artificial lighting, which is sourced from fossil fuel such as natural gas and coal used to generate energy and is only attainable with money, which is grim for underprivileged households. And as the years go by, the world is becoming overpopulated resulting in a lack of space, hence living in a packed area where there are little to no windows and sufficient daylight. Especially in tropical countries where the houses are made darker and roofs are extended to avoid the sun and rain resulting a very dark room/shack.
To solve this problem, Alfredo Moser, a Brazilian inventor, created a cheap and sustainable decent lighting designed for the underprivileged. All it needs is a two litre plastic bottle, filled with purified water and bleach (to keep the water clean), which is measured to be around 40 to 600 watts. Then installed onto the roof of the houses, fixed with polyester resin to avoid leaks. It’s a simple refraction of sunlight, explained Moser. [Gibby Zoel 2013]
With the help of Diaz Illam, a social entrepreneur, they started a global movement called “Litre of Light” which is a not-for-profit organization and is funded by donations and sponsors such as Pepsi, Underground Logic and Orange Fix. Their end goal is to educate the community on how to manufacture and install the solar bottle bulb, in hopes to create new job opportunities for the community.
This would be substantial for the kampung Kali Code as the location is able to absorb more than enough light to illuminate the homes of the Kali Code community.
Global warming is such a broad topic relating to many world wide issues. But one of the leading cause is the excessive use of electricity. This project was created for the people who are struggling to afford decent lighting for their homes (not to mention how this would be ideal for situations such as blackouts), but if this is applied globally at all households, although very unlikely to happen, imagine how much money and energy we could save altogether.
“It’s a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can’t get an electric shock from it, and it doesn’t cost a penny.” – MOSER.
