Liter of Light Switzerland

About us

Liter of Light is a global network of organizations that installs solar bottles – recycled PET bottles filled with water and bleach – to provide an alternative cheap source of light for underprivileged households. The technology of a solar bottle was developed at the Massachusetts Institute of Technology (MIT) and was first implemented in the Philippines in 2009. The idea of illuminating homes through solar bottles spread quickly around the globe to now over 10 national offsprings on three different continents. “Liter of Light Switzerland” is the first European country initiative and aims to support other “Liter of Light” projects in developing countries with fundraising, strategizing and national expansions. Since Switzerland is a well-developed country without social need for solar bottles, the concept of ‘Liter of Light Switzerland’ focuses on cooperating with existing local solar bottle projects or supporting the initiative in new countries. Furthermore, the aim is to facilitate the set up of a global network to build a basis for international cooperation. This should increase awareness for the idea, simplify fundraising and improve cost-efficient sourcing of materials
