The Zephyr is much different from the Global Hawk, which is about the size of a fighter and requires runway for taking off and landing.
Zephyr, on the other hand, is an ultra-lightweight carbon-fiber aircraft that weighs less than 70lbs and is designed to launch by hand. The little aircraft flies on solar power generated by amorphous silicon arrays covering the aircraft's paper-thin wings. It is powered day and night by rechargeable lithium-sulfur batteries that are recharged during the day using solar power."
