Google shows how Project Loon could ride wind currents to keep balloons evenly spaced

Anyone looking to poke a hole in Project Loon — Google's ambitious project to use balloons to bring internet access to remote regions of the world — would likely point out that you can't keep a balloon in one spot. Google has an answer for that, of course. The Project Loon team says it could use wind currents at different levels of the stratosphere to control where balloons move and insure that the "flock" remains evenly spaced out.
