The demonstrator aircraft is a Dimona motor glider, built by Diamond
Aircraft Industries of Austria, which also performed major structural
modifications to the aircraft. With a wing span of 16.3 meters (53.5
feet), the airplane will be able to cruise at approximately 100
kilometers per hour (62 miles per hour) using fuel cell-provided
power.

The glider uses lithium batteries plus the fuel cell to get sufficient
power for launching. According to the Boeing diagram
http://boeingmedia.com/imageDetail.cfm?id=14790&clr=release it has a crazy-tiny
hydrogen (fuel) tank. First, it appears to use compressed hydrogen rather than
liquid hydrogen, but even liquid hydrogen would need significantly more volume
than an equivalent amount of gasoline. Definitely just a technology
demonstration stunt, not a practical aircraft.

That may be true, but it is the coolest v1.0 technology I've seen in a
while.

Yes. No doubt they said much the same about Orville and Wilbur's 1903
Flyer.

This could well be a system to use in Iraq. Electric motor so no
noise. IR and millimeter Radar systems aboard. Could cruise over town
and watch for IED's beng planted without the bad guys knowing they
were being watched.

Hope this is the end result.
