Normal windmills have to stand where there are windy and no buildings that disturbs the flow of the wind.

In Denmark most of the windmills are large expensive mills that small communities share. So if you havent got a windmill community around, you are out of luck - because the market for small household windmills are almost non existent.

Another problem with traditional windmills, are that they are made for a given windspeed, and they are often shut down, in stormy weather, because the construction isnt made for highspeed rotations.

Rumors tell that the sound of the wings on larger windmills, disturb residents living close to the windmill.
  Do you remember how hard doors can slam in the draught througt the house, when somebody, have forgot to close a window, in the other end of the house ?

In the lee side of the house there will always be a little vaacum in stormy weather. And in the windy side, there will pressure. It is this difference in pressure that creates the draught.

Why not use this force for energy production ?

I have used a house as an example, but it could in theory be any obstacle - A forest, a mountain or a large building.
