Would a small windmill generator placed in a truck bed produce enough energy to power the truck (if electric)?

An image taken at or near the Brighton Earthship located near Stanmer Park, Brighton, East Sussex.

The Earthship – the first built in the UK – is an experimental sustainable development which includes the following features: photovoltaic solar cells, collection of rainwater from the roof, a windmill, using the thermal storage property of the ground (by building "hobbit like" into a hillside), reuse of rubber tires as a building material for the walls.

No one lives here, but regular tours are available by arrangement.

Question by somebody: Would a small windmill generator placed in a truck bed produce enough energy to power the truck (if electric)?
If placed in the truck bed it would take drag out of the question and would have wind conditions ideal for its designs. would it be enough to power the truck?
