Inventions in technology never fail to fascinate. There are some recent tech inventions that are helping save the planet. First is old plastic bottles are turned into light bulbs. Plastic bottles filled with a solution of bleached water are installed into roofs and begin working as a mirror on the roof, refracting the light and offering a natural light bulb during the day. The ‘Liter of Light project’ that uses this innovation, was launched to combat the rising cost of electricity in the Philippines.

Liter of Light is a global movement. It uses readily available inexpensive materials to create high quality light using plastic bottles and chlorine. It is helping people with limited or no access to light. Liter of Light, with the help of a network of partnerships around the world, is volunteering to teach marginalized people how to make their own light using plastic bottles and chlorine and illuminate their homes and streets without electricity. Liter of Light has installed more than 3,50,000 bottle lights in more than 15 countries. It has also taught green skills to empower grassroots entrepreneurs at every stop.

Liter of Light’s open source technology has been recognized and appreciated by the United Nations and adopted for use in some UNHCR camps. Liter of Light is the proud recipient of the 2015 Zayed Future Energy Prize, 2016 St. Andrews Prize for the Environment, and a winner of the 2014-2015 World Habitat Award.
