In 2002 a Brasilian mechanic had to face the problem to how illuminate his house during the day without electricity and brilliantly he came up with a terrific however simple idea using just an empty plastic bottle filled with water and a bit of bleach ( two capfuls of bleach to protect the water so it doesn’t turn green with algae).
How is it possible? easy!
With a drill he makes a hole in the roof takes and pushes the bottle upwards through the hole up to half and to seal it, he uses polyester resin, so when it rains, the roof never leaks.
It depends on how strong the sun is but a bottle light can produce more or less from 40 to 60 watts light.
At the begin Moser has installed the bottle lamps in neighbours’ houses and the local supermarket. Slowly people started to put light bottles in their houses.
Within months the idea spreaded, in the Philippines, where 25% of the population lives below the poverty line, and electricity is unusually expensive, the idea has really taken off, with Moser lamps now fitted in 140,000 homes.
The idea has also caught on in about 15 other countries, from India and Bangladesh, to Tanzania, Argentina and Fiji.
Following the Moser method, MyShelter started making the lamps in June 2011. They now train people to create and install the bottles, in order to earn a small income.
Using Moser s lamp, people in poor areas are also able to grow food on small hydroponic farms.
Alfredo Moser has changed the lives of a tremendous number of people all around the world
Did Moser himself imagine that his invention would have such an impact?
“I’d have never imagined it, No,” says Moser, shaking with emotion.
