Video: Navy UAV uses hydrogen fuel cells for greener surveillance

It sure is nice to see that the military is paying attention to the environment, always on the lookout for greener ways to spy on people, foreign and domestic. Ion Tiger, for instance, is an unmanned vehicle being cooked up at the Naval Research Laboratory that incorporates a hydrogen fuel cell, offering many improvements on earlier battery powered designs -- including a greater range (up to seven times further that of current designs), heavier payloads, smaller size, reduced noise, a low heat signature, and zero emissions. The Office of Naval Research is making much of the possible civilian potentials for this technology, pointing out that research contributes "di
