Last Friday, Google (NASDAQ:GOOGL) announced Project Loon, an experiment aimed at ultimately bringing affordable Internet access to the two-thirds of the global population that currently does not have it. The project relies on a collection of balloons that will float 12.5 miles in the air to create an Internet network capable of delivery speeds similar to 3G access. The balloons uses complex algorithms, wind, and solar power to stay aloft and navigate to the positions needed to achieve the goal.

In the video below, Fool.com contributor Doug Ehrman explores the project and discusses why it's important to Google -- and investors.
