Yeah C I now. They're wind powered generators C for emergency electric supply C travelling at 250+ mph!.
There are also wind driven vacuum horns C too. But C we weren't talking about these C either. We were talking about wind driven fuel pumps.
Think about it. Sitting on the runway C zero airspeed C all ready for that long climbout at slow airspeed C and expecting an air driven pump to power your fuel supply. Even Rube Goldfarb woul find it a challenge!!!
You're not suggesting Sully could drop his wind driven generator on the ramp. and furnish cabin air conditioning C are you?

There are wind driven emergency hydraulic pumps on jetliners... ask Capt.
Sullenberger about that one.
