We can’t really use the wind until we catch it. And what’s the most popular way to catch
the wind’s force? A windmill of course, which can do the work of many people. Inside the mill, a pole begins to spin. It goes all the way down into the mill. There it can do some pretty helpful things: It can turn a big stone wheel to crush grain. It can move a saw up and down to cut logs into lumber. It can pull up water from underground, which can be used to water crops.
