Alphabet's Balloon Tech May Yet Deliver The Internet

Alphabet - the parent company to Google - is pressing on with their anachronistic-sounding project to bring Internet connectivity to remote areas of the world - via balloons.

A somewhat similar project using drones has been put aside, but the balloon approach (named Project Loon) is apparently now closer to being a commercial product, following some recent technical progress in actually controlling the swarms of balloons.
The idea was to encircle the globe with a ring of stratospheric balloons and to control their flight in such a manner as to ensure that enough balloons would always be over a particular location to deliver consistent Internet connectivity.
In order to do this, engineers at X have over the years developed and refined algorithms that allow balloons to navigate to where they need to be by constantly inflating and deflating so as to take advantage of wind directions and speed.
