A Unifine mill is a single onepass impact milling system which produces ultrafinemilled wholegrain wheat flour that requires no grain pretreatment and no screening of the flour. Like the grist or stone mills that had dominated the flour industry for centuries, the bran, germ, and endosperm elements of grain are processed into a nutritious whole wheat flour in one step.
Humans have been harnessing water to perform work for thousands of years. The Greeks used water wheels for grinding wheat into flour more than 2,000 years ago. Besides grinding flour, the power of the water was used to saw wood and power textile mills and manufacturing plants.

Solar cells were too expensive for smallscale electrical generation, so some turned to windmills. At first they built adhoc designs using wood and automobile parts. Most people discovered that a reliable wind generator is a moderately complex engineering project, well beyond the ability of most amateurs.
First examples of Post Mills started being made around 11th century, with more advanced models of Tower and Smock mills being made in the following centuries. Two countries that were home of the most wind mills were England and Netherlands, but many other European countries also adopted windmills and their usefulness.
Not much later in the history of hydroelectric power, around the 2nd century BC, watermill devices were invented and probably originally used for grinding grains. These mills were usually vertical axis mills and were built and used throughout the ancient greek and roman empires.
