In June 2013, Google launched an interesting experiment Google Loon. A lot of balloons on solar batteries to be cruising in the stratospheric winds at an altitude of 20 km. the Winds at that altitude are constant, steady and often blow parallel to the equator, so that the balls shall revolve around the planet on the same parallel with the speed of 8-30 km/h. due to the large number of balls can provide complete covering of the Internet of the earth's territory for a specific parallel. At least in theory.
The experiment is still ongoing, and recently one of the balls managed to show an incredible result. By varying the height and jumping in different stratospheric flow, the balloon Ibis-167 was able to go around the Earth in just 22 days!
