Day of Light


The Day of Light is a crowdsourced initiative to collect money to sustainably illuminate family houses in Santiago del Estero, Argentina – an area where communities often have little or no access to electricity.

Based on a discovery made by students of the Massachusetts Institute of Technology (MIT) in the US, the Day of Light is installing solar lamps that consist of plastic drink bottles filled with distilled water and bleach to the ceilings of houses. During the day, sunlight is refracted through the plastic bottle, illuminating dark rooms and creating the equivalent amount of light to a 55-watt bulb.

The initiative hopes to raise further funds to travel to the rural Argentinian communities of Salta, Misiones and the Buenos Aires Delta, to train the locals to make solar lamps themselves.
