Windmills harness the power of wind to turn mill wheels to grind grain. That’s why they are called windmills. When you see a whole slew of windmills, you have to wonder why a town would need more than one mill to grind everyone’s grain. That’s American thinking. In the village of Kinderdijk in the Netherlands, there are 19 "windmills" that are actually water pumps, built between 1738 and 1740. The pumps are necessary because the land is below sea level!
