Qinetiq's Zephyr Solar-Powered Plane
Very cool stuff. A lightweight solar-powered plane has smashed the official world record for the longest-duration unmanned flight.
UK defence firm Qinetiq, which built the Zephyr unmanned aerial vehicle, said it flew for 54 hours during tests. The researchers believe it is the first time a solar-powered craft has flown under its own power through two nights…On the first flight, the aircraft, which has a wingspan of 18m (59ft), flew for more than two days before it developed a fault. The second, shorter flight was curtailed when thunderstorms threatened the propeller-driven plane.

Comments are sorta kinda broken right now. We're working on it but to save energy can only work in daytime when solar system is at peak performance.
