Some bacteria get around my means of a long, whip-like tail called a flagellum. These bacteria look like tadpoles swimming around by the propulsion of these rapidly spinning tails. The flagellum rotates by means of a complex motor with some 40 different components, 30 of which are completely unique to the flagellar motor. The smallest electric nano-motor man has built is still the size of a housefly. The flagellar motor is one millionth of an inch in diameter. Top speed of these motors is 100,000 RPM (to scale). The cell travels at a speed of 15 body-lengths per second. This would be like a six-foot human swimming at 60 MPH! The motor can reverse direction almost instantaneously. Man-made electric motors operate at 75-95% efficiency and bog down with friction at smaller sizes. The flagellar motor operates at near 100% efficiency, only using 2% of the bacterium’s energy for swimming. Man’s best effort at an efficient motor is clumsy and primitive compared to this complex and efficient design. A result like this demands a Designer with the wisdom and skill to build it. That Designer is none other than the eternal God of the Bible.
