I can hardly wait to see the look on the pilot's face when the L/D numbers drop dramatically while trying to regenerate power with a windmilling prop.

Regenerating upon descent might have real value for an electric powered towplane,
as the pilot typically wants to get down as rapidly as possible. Shock cooling
would not be an issue :^)
