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.

Europe Angered By News Of NSA Spying On EU Offices

Europe Angered By News Of NSA Spying On EU OfficesEuropean officials reacted with fury Sunday to a report that the U.S. National Security Agency spied on EU offices. The European Union warned that if the report is accurate, it will have tremendous repercussions.

‘Electronic eavesdropping operation’

The outrage from European officials over the weekend was the latest fallout since Edward Snowden, a former National Security Agency computer contractor, started spilling details of U.S. surveillance programs to reporters earlier this month.

Citing information from secret documents obtained by Snowden, the German news magazine Der Spiegel reported Sunday that several U.S. spying operations targeted European Union leaders. Der Spiegel said it had “in part seen” documents from Snowden that describe how the National Security Agency bugged EU officials’ Washington and New York offices and conducted an “electronic eavesdropping operation” that tapped into a EU building in Brussels, Belgium.


‘Seeking asylum’

The Guardian newspaper reported that one NSA document leaked by Snowden describes 38 embassies and missions as “targets” and details surveillance methods that include planting bugs in communications equipment and collecting transmissions with specialized antennae. Targets included France, Italy, Greece, Japan, Mexico, South Korea, India and Turkey, according to The Guardian.

Snowden has revealed himself as the source of documents outlining a massive effort by the NSA to track cell phone calls and monitor the e-mail and Internet traffic of virtually all Americans. Critics slam him as a traitor. Supporters hail him as a hero. Now Snowden, who faces espionage charges in the United States, is in Russia and seeking asylum from Ecuador.

Do you believe the NSA was really spying on EU offices? What impact could this report have on the relations between the U.S. and Europe?
