"Man-made motors are complex designs, because they need many parts working together to function. Although miniaturised motors would be very useful, e.g. for keeping our arteries clear and our blood clean, the number of parts makes it difficult to make them below a certain size. But ingenious scientists are making them smaller all the time.

However the design in living organisms has far exceeded our most painstaking efforts. Bacteria propel themselves using flagella, filaments propelled by a true rotary motor. This motor is only the size of a virus, thus far smaller than anything man-made. Yet it can rotate at over 1000 times per second.

But even this impressively tiny motor is not the tiniest in God's creation. Living cells have many molecules that are mini-machines and chemical factories enzymes. One enzyme has been shown to spin 'like a motor' to produce ATP, a chemical which is the 'energy currency' of life. The enzyme, which has nine protein components, is so tiny that 100,000 million million would fill the volume of a pinhead. This motor produces an immense torque (turning force) for its size it rotates a strand of another protein 100 times its own length. Also, when driving a heavy load, it probably changes to a lower gear, as any well-designed motor should."  J.D. Sarfati, 'Design in Living Organisms: Motors'
