Great Question of 21st Century :P 
Google’s mission is to organize the world’s information and make it universally accessible and useful.
BALLOON-POWERED INTERNET FOR EVERYONE
Many of us think of the Internet as a global community. But two-thirds of the world’s population does not yet have Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters.
Project Loon balloons float in the stratosphere, twice as high as airplanes and the weather. They are carried around the Earth by winds and they can be steered by rising or descending to an altitude with winds moving in the desired direction. People connect to the balloon network using a special Internet antenna attached to their building. The signal bounces from balloon to balloon, then to the global Internet back on Earth.
Project Loon began in June 2013 with an experimental pilot in New Zealand. A small group of Project Loon pioneers tested the technology in Christchurch and Canterbury.
