Project Loon is a Google initiative to provide internet access to rural and remote areas using a network of balloons traveling in the stratosphere. The balloons float 20 km above the Earth's surface and are steered by rising and descending to altitudes with winds moving in the desired direction. People on the ground connect to the balloon network using special antennas. Each balloon is powered by solar panels and contains equipment like antennas and batteries to communicate with other balloons and transmit internet signals to users below. The goal is to bring internet access to places that lack reliable connectivity.
