Helicopters as windmills?

Would a helicopter make a good makeshift windmill?

This came up in discussion about a post-apocalyptic scenario where stranded military personnel have to live off the land. I had this idea of a helicopter-using military unit converting their helicopters to windmills. (Imagine a row of military helicopters standing on their tails on the side of an airbase runway.) The basic idea is to just lift the helicopter on it's tail and either extract the energy at the tail rotor or just replace the engine with a generator. Obviously this would not be the most efficient wind-generator available, but just how unefficient would it be? Would the rotor blades be any good as windmill blades?
