Small drone sails through hurricane while livestreaming

Sail drones, unmanned sailboats with robotic brains, are being tested by the US Navy to integrate new unmanned systems and AI into operations. These drones are powered by wind and solar energy, allowing them to stay at sea indefinitely. A modified sail drone, SD1045, successfully sailed into Hurricane Sam, providing live data despite extreme weather conditions.
