BOTTLE LIGHTS BY ALFREDO MOSER

 

 

Brazilian engineer Alfredo Moser came up with an ingenious invention around a decade ago that brought light into his home during blackouts.

Using just a 2L plastic bottle filled with water and a little bleach, he inserts it into a sealed hole in the roof. Sunlight is then refracted through the bottle into the building, providing a light source equivalent to around 40 to 60 watts.

Recently the idea has spread to many underprivileged communities around the globe, providing interior lighting during daylight hours in places that cannot access or afford electricity.

A recent BBC article reported that Moser’s idea is expected to help light one million homes by next year.
