Great video humy. Liked it very much. I remember some of that since university but it was a great review.
I also remember that we read in great detail about Salmonella. That thing has 'needles' which it builds. Penetrating the cell. If you look in a textbook you'll see that there are like 10 different needles that looks different for each specie of salmonella.

False inference; your use of the word “therefore” is stupidly invalid and arbitrary. Tell us, where exactly is the logical contradiction in no motor made by man being more efficient than flagella motors and those flagella having evolved without intelligence involved?
Your premise is also false: the most energy efficient motors invented by man are electric motors with the most efficient being more than 98% energy efficient and can even potentially be made to be 99.99% energy efficient with superconductors while those evolved in living things are generally less than 98% energy efficient. for example:
"....myosin (a type of a molecular motor) converts chemical energy (i.e. ATP) to mechanical work with 90 percent energy efficiency....."
-and 90% is LESS than 98%

The link is actually about primary cilium but scroll about half way down this link to get to the video. Personally I liked this video.
That was amazing!!! Bearings and a motor. I think it was interesting that it is a motor that turns the flagellum rather than some system that allowed it to waggle for locomotion. I did find myself getting hungry for squeaky cheese curds as the animation progressed to the building of the flagellum.
