The Korea Advanced Institute of Science and Technology (KAIST) has built and demonstrated a new unmanned aerial vehicle (UAV) that can fly for up to ten hours using 500 grams of liquefied hydrogen fuel. The hydrogen is the energy carrier which appears to provide electricity to an electric motor via ...

Usually, when we cover things like airplanes, it's because they are powered by alternative energy sources, like solar. Sometimes, we focus on flying machines which are lighter than air. This one, though, has caught our interest for another reason entirely, namely, taking detailed pictures and ...

Sporting a 59 foot wingspan, the Qinetiq unmanned aerial vehicle is likely capable of setting a new world record for sustained unmanned flight. The previous record was set in 2001 by a jet-powered vehicle. The Qinetiq Zephyr, on the other hand, is powered by nothing but sunlight. The solar craft ...

I just ran across this very in-depth article that introduces us to a new team, the Technion Israel Institute of Technology, Haifa, who hopes to rewrite the record books when it comes to solar aviation. They are doing so with a rather small airplane (compared to previous solar fliers) known as ...

It appears as though military contractors aren't the only ones making headway on the development of unmanned aerial vehicles powered by fuel cells. In a collaboration between Georgia Tech's Aerospace Systems Design Laboratory (ADSL) and the Georgia Tech Research Institute (GTRI), researchers have ...

Protonex, an advanced fuel cell power systems provider to the US military, will be unveiling it's new fuel cell system in an upcoming meeting for the Association of Unmanned Vehicle Systems International (AUVSI).As unmanned aerial vehicles (UAVs) demand longer flight durations, they push the limits ...
