Brazilian Mechanic Invents Light In A Bottle With Water And Bleach

Brazilian Mechanic Invents Light In A Bottle With Water And BleachIn 2002, the Brazilian mechanic Alfredo Moser had a light-bulb moment and came up with a way of illuminating his house 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.

‘Moser lamp’

“Add two capfuls of bleach to protect the water so it doesn’t turn green [with algae]. The cleaner the bottle, the better,” he adds. ”You fix the bottle in with polyester resin. Even when it rains, the roof never leaks – not one drop… An engineer came and measured the light,” he says. “It depends on how strong the sun is but it’s more or less 40 to 60 watts,” he says.

The inspiration for the “Moser lamp” came to him during one of the country’s frequent electricity blackouts in 2002. Moser and his friends began to wonder how they would raise the alarm, in case of an emergency, such as a small plane coming down, imagining a situation in which they had no matches.


‘Great sense of pride’

Soon he had developed the lamp. Moser has installed the bottle lamps in neighbours’ houses and the local supermarket. While he does earn a few dollars installing them, it’s obvious from his simple house and his 1974 car that his invention hasn’t made him wealthy. What it has given him is a great sense of pride.

Illac Angelo Diaz, executive director of the MyShelter Foundation in the Philippines that specialises in alternative construction, started making the lamps in June 2011. They now train people to create and install the bottles, in order to earn a small income. In the Philippines, where a quarter 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.

Tourist’s Body Found In Hotel’s Water Tank

Tourist's Body Found In Hotel's Water TankTourists staying at a Los Angeles hotel bathed, brushed teeth and drank with water from a tank in which a young woman’s body was likely decomposing for more than two weeks, police said. Elisa Lam’s corpse was found in the Cecil Hotel’s rooftop water tank by a maintenance worker who was trying to figure out why the water pressure was low Tuesday.

‘Suspicious death’

Lam’s parents reported her missing in early February. The last sighting of her was in the hotel on January 31, Los Angeles Police said. Detectives are now investigating the 21-year-old Canadian’s suspicious death, police Sgt. Rudy Lopez said.

It was not clear whether the water presented any health risks. Results on tests on the water done Wednesday by the Los Angeles Public Health Department were expected later in the day. People who stayed at the Cecil since Lam’s disappearance expressed shock about developments.

‘Funny taste’

“The water did have a funny taste,” Sabrina Baugh told CNN on Wednesday. She and her husband used the water for eight days. We never thought anything of it. We thought it was just the way it was here… The shower was awful,” she said. “When you turned the tap on, the water was coming black first for two seconds and then it was going back to normal.”

The hotel remained open after the discovery, but guests checking in Tuesday were told not to drink it, according to Qui Nguyen, who decided to find a new hotel Wednesday.

What do you think is the real cause of Elisa Lam’s death? And how did she end up in the water tank? Feel free to share your speculations with us here via the comment box below!
