It aims to temporarily re-establish Puerto Rico's cellular network - where 83 per cent of cell sites were still out of service on Friday (Oct 6), according to FCC figures.
According to Wired, Project Loon-which is described as "a network of balloons traveling on the edge of space, created to extend Internet connectivity to people in rural and remote areas worldwide"-would allow Puerto Rico residents to get voice and data service".
Most of the recovery news has rightly focused on the hard journey to get Puerto Rico's power grid back online.
Google is stepping into the crisis in Puerto Rico to help out with some cutting edge technology that will provide emergency phone reception.
Alphabet has confirmed it plans to use solar-powered, high-altitude balloons to support the restoration of "limited communications capability" in the U.S. unincorporated territory.
Just last week, the Loon team said it was looking into helping Puerto Rico, still devastated by Hurricane Maria, regain connectivity.
As Wired points out, Alphabet used the balloons to provide phone service in Peru after flooding ravaged the country, but Puerto Rico might be a little tougher.
In 2016, a test site was set up in Puerto Rico to launch what the project called "a handful of test balloons". But in that case, Google had already partnered with a telecom provider on the ground, which it depended on to beam the signal to the balloons, for disaster relief.
