A group of four autonomous underwater vehicles have just set a world distance record, by traveling from San Francisco to Hawaii
Each Wave Glider consists of a floating "boat" tethered to an underwater winged platform

On November 17th of last year, a group of four wave-powered autonomous aquatic robots set out from San Francisco, embarking on a planned 37,000-mile (60,000-km) trip across the Pacific ocean. Recently, the fleet of Wave Gliders completed the first leg of their journey, arriving at Hawaii’s Big Island after traveling over 3,200 nautical miles (5,926 km). By doing so, they have set a new distance record for unmanned wave-powered vehicles – that record previously sat at 2,500 nautical miles (4,630 km).
