The Mechanic Who Is Lighting Up the World

Moser lamp
In 2002, Brazilian mechanic Alfredo Moser figured out a way to illuminate his home without using electricity. His idea was simple— it involved clear plastic bottles filled with water and a small amount of bleach to protect the water from algae. After drilling a hole in his roof, Moser pushed the two-liter bottle up and through the hole, exposing it to sunlight. The water’s refraction of the sunlight created an illuminating effect equal to that of a 60-watt light bulb. Moser’s lamp is now being used to light up the world.

The MyShelter Foundation, an organization that brings sustainable building solutions to poorer regions of the Philippines, has used the Moser lamp to light up more than 140,000 homes. Use of the lamps has also spread to 15 other nations. MyShelter hopes to have one million lamps installed around the world by 2015. The organization also trains individuals to make and install the lamps, which helps them earn a small income. “Alfredo Moser has changed the lives of a tremendous number of people, I think forever,” said Illac Angelo Diaz, the executive director of MyShelter.

In fact, Moser’s lamp has the potential to change the lives of billions of people. The World Bank estimates that more than 1.2 billion people do not have access to electricity. That means 20 percent of the world’s population cannot turn on the lights. Though Moser’s lamp can only be used during the day, it is beneficial for people who live in shacks and huts that are often dark and windowless. According to the United Nations, the lamp refracts light 360 degrees and can reach all corners of a 40 square meter room.

In terms of cost, most of the bottles are upcycled and the cost of installation is less than a U.S. dollar. The United Nations estimates the monthly electricity savings are almost $6. It would be difficult to find illumination that is cheaper or more sustainable than the Moser lamp.

Though Moser has earned little from his invention, it has been a great source of pride. In an interview with the BBC, Moser said that he could never have imagined that his idea would have such an impact on people throughout the world. “It’s a divine light,” he said. “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.”

Liter of Light

Liter-of-Light

Fiat lux! Let there be light! A timeless phrase that has been used since biblical times, in classrooms and even in movies has a more humanitarian and sustainable meaning since 2011. MyShelter Foundation, a ‘green-energy for all’ organization, began the Liter of Light project out of a simple idea to light up the homes of those who could not afford to do so themselves. With the help of MIT students, the technology of empty water bottles, water, bleach, and a slab of cement has taken the place of electricity and changed the lives of hundreds of thousands of people around the world.

The first installments began in Manila, Philippines. Since electricity rates are so high, families are forced to keep the lights off during the day. Due to the infrastructure of the homes in many of the poorer areas, however, light does not enter the homes during the day and families are left in darkness.

Building the makeshift light bulbs is easy and requires little to no maintenance. 1 liter plastic bottles are taken, filled with a small amount of bleach to keep the water and bottle clean and free of germs, then filled with water. When sunlight enters the bottle, enough light is produced that equals that of a 55-watt light bulb! The benefits of the water bottle bulbs are endless. Not only do they eliminate the need for electricity during the day, but they also reduce monthly electricity costs, are sustainable, help keep slums free of plastic waste, are easy to install, and add a greater sense of well being to the home environment.

Since 2011, Isang Litrong Liwanag (the translation of Liter of Light in Filipino) has spread to other countries such as Cambodia, India, Vietnam, Spain, Egypt, Peru, Kenya, the Middle East, and even Switzerland. MyShelter hopes to reach its goal of installing 1 million water bottle light bulbs by 2015.
