As the world turns to electric power and away from engines, it turns more and more to motors of all sizes and power levels. Eventually, as the world moves away from using fossil fuels like gasoline, machine movement and power will increasingly be the byproduct of motors. Motors are already everywhere things move. They are often taken for granted when we see doors open, printers print, and gigantic structures delicately eased into place. Motors do not directly require fuel to operate. The electricity that drives them can be generated by any number of energy sources.
