Solar Bottle Bulb - Illuminating Houses For Even The Poorest Families, During The Day Without Electricity

In 2002, a Brazilian mechanic 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. In the last three years his innovation has spread throughout the world and now in millions of homes. Each bottle averages an equivalent output of a 50 watt bulb.

For humans, sunlight and vitamin D is critically important for the development, growth, and maintenance of a healthy body, from birth until death. "Humans make thousands of units of vitamin D within minutes of whole body exposure to sunlight. From what we know of nature, it is unlikely such a system evolved by chance." states Dr. John Cannell, Executive Director, Vitamin D Council. We need natural light at all times during the day to help improve our mood and health.

How Does The Solar Bottle Bulb Work?

So how does it work? Simple refraction of sunlight, explains Moser, as he filled an empty two-litre 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," he adds.

Wrapping his face in a cloth he makes a hole in a roof tile with a drill. Then, from the bottom upwards, he pushes the bottle into the newly-made hole.

"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. "The only places that had energy were the factories - not people's houses," he says, talking about the city where he lives, Uberaba, in southern Brazil.

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.

His boss at the time suggested getting a discarded plastic bottle, filling it with water and using it as a lens to focus the sun's rays on dry grass. That way one could start a fire, as a signal to rescuers. This idea stuck in Moser's head - he started playing around, filling up bottles and making circles of refracted light.

Soon he had developed the lamp.

"I didn't make any design drawings," he says.

"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 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.

"There was one man who installed the lights and within a month he had saved enough to pay for the essential things for his child, who was about to be born. Can you imagine?" he says.

Carmelinda, Moser's wife of 35 years, says her husband has always been very good at making things around the home, including some fine wooden beds and tables.

But she's not the only one who admires his lamp invention. Illac Angelo Diaz, executive director of the MyShelter Foundation in the Philippines, is another.

MyShelter specialises in alternative construction, creating houses using sustainable or recycled materials such as bamboo, tyre and paper.

"We had huge amounts of bottle donations," he says.

"So we filled them with mud and created walls, and filled them with water to make windows.

"When we were trying to add more, somebody said: 'Hey, somebody has also done that in Brazil. Alfredo Moser is putting them on roofs.'"

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.

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.

Even Wikihow demonstrates how easily a DIY solar bottle bulb can be made and installed. "For adding light to a temporary structure or a playhouse for kids, a solar bottle bulb can be easily fashioned," they stated.

The idea has also caught on in about 15 other countries, from India and Bangladesh, to Tanzania, Argentina and Fiji.

Diaz says you can find Moser lamps in some remote island communities. "They say, 'Well, we just saw it from our neighbour and it looked like a good idea.'"

People in poor areas are also able to grow food on small hydroponic farms, using the light provided by the bottle lamps, he says.

Overall, Diaz estimates, one million people will have benefited from the lamps by the start of next year.

"Alfredo Moser has changed the lives of a tremendous number of people, I think forever," he says.

"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."

Did Moser himself imagine that his invention would have such an impact?

"I'd have never imagined it, No," says Moser, shaking with emotion.

"It gives you goose-bumps to think about it."

House unexpectedly votes to stop warrantless NSA searches


House unexpectedly votes to stop warrantless NSA searches

In what’s being billed as a momentum boost for anti-surveillance advocates, the US House of Representative on Thursday approved an amendment that significantly reigns in warrantless searches on Americans’ communication records.

By a vote of 293 to 123, a bipartisan coalition in the House voted to ban the National Security Agency from conducting “backdoor searches” on United States citizens, a process that allowed the intelligence community to collect data on Americans without a warrant as long as the official target was a foreigner. The program was first revealed by the Guardian, through documents leaked by Edward Snowden.

The NSA has argued that when a US citizen engages in communication with a foreigner it has targeted for surveillance, the spy agency can legitimately store the data – email, phone, and text conversations – in a database and search through it at any time for information on US citizens. The House vote comes amid rising concerns over the potential for the NSA to continue expanding its collection of data on Americans.

According to the Huffington Post, the amendment “specifically prohibits the NSA from using information identifying U.S. citizens to search communications data it collects under the Foreign Intelligence Surveillance Act.”

Additionally, the House voted to ban the NSA from installing backdoor search capability into the hardware and software of other companies, which has allowed the agency to gain easy access to customer communications data.

"I think people are waking up to what's been going on," amendment's sponsor, Rep. Thomas Massie (R-Ky.), told the Post. "Whether you're Republican or Democrat -- because, if you noticed, a majority of Republicans voted for this, as well as a majority of Democrats."

The action by the House also comes in the wake of a previous vote that authorized the USA Freedom Act, which aimed to block the NSA’s bulk collection of metadata but was significantly watered down after negotiations with the White House and the intelligence community. Loopholes were put in place to allow continued surveillance and, as RT reported in May, other provisions were removed that forced civil liberties advocates to drop their support for the bill.

The most recent amendment reinstated the provisions that were cut out previously and, as a result, earned the backing of the American Civil Liberties Union, Google, and others.

“Tonight's overwhelming vote to rein in the NSA's backdoor access to Americans' data signals widespread discontent amongst House members over how the USA Freedom Act was watered down by the House leadership in secret negotiations with the intelligence community,” Kevin Bankston, policy director at the New America Foundation's Open Technology Institute, said to the Daily Beast.

Aware that the restrictions won’t take effect unless they are approved by Congress as a whole, Bankston urged the Senate to pass a similar measure as a comprehensive defense appropriations bill makes its way to President Obama’s desk.

Despite the overwhelming passage, the amendment faced numerous obstacles before its passage. Massie told the Post that House leaders did not lend their support, and that it was only by having bipartisan co-sponsors that it was able to come up for a vote.

As noted by the Daily Beast, NSA supporters also criticized the quick rush to vote on the amendment, believing the agency’s behavior is within the confines of the law and that weakening it will also diminish the US’ national security.

“We shouldn't be doing this on an appropriations bill after only 10 minutes of debate,” said Rep. Dutch Ruppersberger (D-MD).

Speaking with the Guardian, ACLU deputy legal director Jameel Jaffer argued that regardless of who the NSA’s official targets are, the ends don’t justify the means when it comes to searching the private records of US citizens.

"The mere fact that the government’s 'targets' are foreigners outside the United States cannot render constitutional a program that is designed to allow the government to mine millions of Americans’ international communications for foreign intelligence information," he said.

Whether or not an appropriations bill containing the amendment’s strong language makes its way to Obama remains to be seen, however. Massie was pleased with the vote, but acknowledged that getting the Senate onboard and merging the two versions in conference will be a challenge.

"That's going to be the trick," he told the Post. "It would take somebody to support it on the Senate side as well, and in conference.”
