Illac Diaz is a social entrepreneur and founder of MyShelter Foundation and Liter of Light. Liter of Light is a global, grassroots movement committed to providing affordable, sustainable solar lights to people with limited or no access to electricity. The concept is simple: collect plastic bottles, ll them with water and bleach, and install them on rooftops. The bleach- lled bottles then refract the light from the outdoors into the house, lighting
up like a lightbulb. They also can be upgraded with an LED bulb, micro-solar panels and a battery to provide a low cost night-time lighting system.

Liter of Light has installed more than 450,000 bottle lights in more than 15 countries, as well as a few thousand streetlights. Liter of Light’s open source technology has been recognized by the UN and adopted for use in some UNHCR camps.
Liter of Light is the recipient of the 2016 St Andrews Prize for the Environment, the 2015 Zayed Future Energy Prize and a winner of the 2014-2015 World Habitat Award.
