Here is my suggestion for the drop down alternator. Real cheap.

Wouldn't it be better to have the fan/alternator inside the fuselage
with the door flat with the bottom? This way would serve to eliminate
unnecessary drag &/or turbulence when not in use.

Please, correct me if I'm wrong.

Most people would object to cutting into the fuselage skin for structural
reasons. Each airplane is different. On some this would be very important
and others could accommodate it easily. An external drop down alternator
would work on all types of airplanes without affecting the structure.
