Liter of Light Europe

Liter of Light Europe is part of a global open source network with the aim to spread an alternative cheap source of light.

A normal PET-Bottle filled with water can be used as a light bulb to bring light into underprivileged households during the day. The plastic bottle is filled with only water and bleach. The liquid inside the bottle harnesses the light from the sun, capturing and diffracting the light to all parts of the room. It is equivalent to a 55 watt light bulb. The Swiss organization was founded by 10 graduate students from the University of St.Gallen in Fall 2011.
