Liter of Light is a global open source movement aiming to provide ecologically sustainable and cost-free lighting for simple dwellings with thin roofs. The device is simple: a transparent 1.5–2 L plastic bottle, as typically used for carbonated drinks, is filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof. The device functions like a deck prism: during daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40–60 watt incandescent bulb to the interior.
A Brazilian mechanic is bringing light to the masses.
With just a plastic bottle, water, and bleach, Alfredo Moser has found a way to produce a light that is up to 40 or 60 watts — stronger than some light bulbs.
The impact of Moser’s invention has been nothing short of phenomenal. In June 2011, My Shelter Foundation in the Philippines launched its “Liter of Light” campaign and began to train people on how to create and install the bottles in exchange for a small income. Since the project began, the lamp has been installed into 140,000 homes as an effective means of saving money on expensive electricity.
By next year, the “Moser lamp” is expected to brighten the lives of at least one million people — at their homes, schools, or stores. It’s already made headway in at least 16 countries, including the Philippines, India, Bangladesh, Tanzania, Argentina, and Fiji….
