Project Loon is a network of balloons traveling in the stratosphere designed by Google to provide internet access to rural and remote areas. The balloons float twice as high as airplanes and are moved around the globe by wind currents. Special antennas on buildings allow people to connect to the balloon network. Each balloon uses GPS and software algorithms to navigate wind patterns and position itself within the network to provide internet coverage. Project Loon aims to give 3G-level internet access to the two-thirds of the world currently without reliable connectivity and help reconnect people after natural disasters.
