Submission + - Moser Lamps Illuminate Homes Without Using Electricity

Hugh Pickens DOT Com writes: Gibby Zobel reports at BBC on Alfredo Moser, a Brazilian mechanic, whose invention illuminates over one million homes during the day without electricity — using nothing more than plastic bottles filled with water and a tiny bit of bleach. So how does it work? Simple refraction of sunlight, explains Moser, as he fills an empty two-liter plastic bottle. "Add two capfuls of bleach to protect the water so it doesn't turn green [with algae]. The cleaner the bottle, the better," Moser adds. "You fix the bottle in with polyester resin. Even when it rains, the roof never leaks — not one drop." While A 50 Watt light bulb running for 14 hours a day for a year has a carbon footprint of nearly 200kg CO2, Moser lamps emit no CO2 and the plastic bottles are up-cycled in the local community, so no energy is needed to gather, shred, manufacture and ship new bottles. 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. The idea has really taken off in the Philippines, where a quarter of the population lives below the poverty line, and electricity is unusually expensive, with 140,000 homes now fitted with Moser lamps. The idea has also caught on in about 15 other countries, from India and Bangladesh, to Tanzania, Argentina and Fiji. "Alfredo Moser has changed the lives of a tremendous number of people, I think forever," says Illac Angelo Diaz. "Whether or not he gets the Nobel Prize, we want him to know that there are a great number of people who admire what he is doing."

I've got a bad feeling about this.
