Isang Litrong Liwanag,

Not to worry ...about the pronunciation... 
Millions of Filipinos taking their name every " Day" for the invention...the revolution called  Isang Litrong Liwanag (A Liter of Light). 
Kudos to students from the Massachusetts Institute of Technology (MIT).  Based on  simple physics  utilised in the project these students lit a light in to so many slum lives with the help of Mr.Illac Diaz of My shelter foundation. 
The students found that a one liter plastic bottle filled with bleach water and installed on top of a metal roof is a surprisingly simple way to light homes that have neither electrical connectivity nor natural lighting. 
The plastic defracts light and pushes it to every corner of a small slum house instead of beaming it onto one area like a typical lamp might.  
From this innovation inspired and a team of IIT-Bombay students working on Govandi slums now.  here some inspiration...
