Thus, technology can consist not only of tools such as hammers and saws, but also the knowledge of how to make and use those tools and the broader system of which they are a part. For example, a grist mill involves a power source, transmission gearing, stone grinding wheels, barrels, a building to house it all, and, of course, some sort of ...

The fiber from nearly any plant or tree can be used for paper. However, the strength and quality of fiber, and other factors that can complicate the pulping process, varies among tree species. In general, the softwoods (e.g., pines, firs, and spruces) yield long and strong fibers that impart strength to paper and are used for boxes and packaging.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:

Today, the windmill's modern equivalent – a wind turbine – can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy ...
