More than half of the world's population is still without Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to extend Internet connectivity to people in rural and remote areas worldwide.
Project Loon balloons are designed and manufactured at scale to survive the conditions in the stratosphere, where winds can blow over 100 km/hr and the thin atmosphere offers little protection from UV radiation and dramatic temperature swings which can reach as low as -90°C. Made from sheets of polyethylene, each tennis court sized balloon is built to last more than 100 days in the stratosphere before returning to the ground in a controlled descent.
High speed internet is transmitted up to the nearest balloon from our telecommunications partner on the ground, relayed across the balloon network, and then back down to users on the ground.
All the equipment is highly energy-efficient and is powered entirely by renewable energy – with solar panels powering daytime operations and charging a battery for use during the night.
