Mr Illac Diaz’s project combines a recycled plastic bottle, a capful of bleach and distilled water and the result is the ‘Litre of Light’ which provides light to more than 350,000 households in ten countries around the world  without the need for electricity.

This low cost, sustainable design is now a global movement for which the process and  the instructions are entirely open-sourced and spread using traditional and digital social networks.

Illac has been nominated for the Guardian’s International Achievement Award 2013 and the deadline to vote is midnight GMT on Monday 16 September 2013.

Cast your vote for Illac NOW and be part of the Liter of Light revolution.
