This is the wrong approach even though it might be worth experimenting. The correct approach is Kitepower which is simply a kite with minimal electronics to steer and pull out a cable and power a winch. Much simpler and cheaper to build. This produces more power than windmills with far less resources.

EDIT: I guess the proper term is Crosswind kite power. Or maybe Rigid kite (airborne wind energy)

You could attach the kites to the blimp though? I'd imagine you could make the ground tether/power cable cheaper and lighter by using a heavier duty transformer with higher voltage, which would be more viable on the blimp. Then have the blimp spread out a fleet of kites when at correct altitude with simpler electronics.
