It might not sound like much, this 78 mile flight, but the recent journey by the Pterosaur Unmanned Aerial Vehicle (UAV) was actually a record-breaker.
Powered by hydrogen fuel cells, the Pterosaur flew 28 miles farther than the previous record for micro-UAVs, which weigh in at around 11 pounds or less, and its developers say it only used a fraction of the fuel in its tank. Eventually they claim it should be able to go 310 miles. Singapore-based Horizon Fuel Cell Technologies developed the propulsion system in conjunction with scientists at several U.S. universities.—Gregory Mone
