They navigate using an algorithm that puts them in the best position to deliver signal by rising and falling to ride wind currents. They are also solar-powered and only provide signal during the day
Several more balloons are on their way from Nevada, and Alphabet has been authorized by the Federal Communications Commission to send up to 30 balloons to serve hard-hit areas, according to Libby Leahy, spokeswoman for Alphabet's X, its division for futuristic technologies.
