The document discusses Liter of Light, a movement started by Alfred Moser and MIT students to provide solar-powered lighting to communities without electricity. They developed a 55-watt solar bulb made from an old plastic water bottle filled with water and chlorine that refracts sunlight. Known as the "Liter of Light", this inexpensive and easy to make bulb has now brightened over 28,000 homes and impacted the lives of 70,000 people in Manila, and the movement has expanded to other countries including India, Indonesia, and Switzerland.

2. The Technology
What do you get with sunshine and an old plastic bottle filled
with water and chlorine? Thanks to Alfred Moser and a group
of MIT students, you get a 55-watt solar bulb that refracts
sunlight! It’s powerful enough to light up a home but more than
that it’s environmentally friendly, inexpensive, and easy to
make.

3. About Liter of Light
Bringing eco-friendly bottle light to communities living without
electricity.
The Movement
The Liter of Light began in
the Philippines with one
bottle light.
Eventually, the movement
grew to brighten up 28,000
homes and the lives of
70,000 people in Metro
Manila alone.
Now Liter of Light is present
in India, Indonesia, and even
as far away as Switzerland.
Our latest project is the Liter
of Light or Isang Litrong
Liwanag.
