Windmills

Nowadays, windmills are at work only in under-developed countries, or preserved for the sake of the past and because they are beautiful and interesting, not because they are practical economic propositions. The problem is the same as it has always been -- that wind power is not constant. Most windmills have gone, both here and in Europe, but just before it was too late to save them, many were renovated or preserved. This work is still going on. - Introduction.
