Single-molecule experiments reveal force capability of artificial molecular motors:
National University of Singapore physicists have shown that a single man-made molecular motor can exhibit a force similar to naturally occurring ones that power human muscles. Their results are published in Nanoscale.
Molecular motors are a class of machines with nanoscale dimensions that are essential agents of movement in living organisms. They harness various energy sources within the body to generate mechanical motion. A key characteristic is the force generated by a single motor during its self-propelled motion. This force generation capability allows the molecular motor to deliver mechanical work and is a measure of its energy conversion efficiency, which influences its use in potential applications.
[...] The research team successfully applied their method to an autonomous DNA molecular motor (previously developed by Prof. Wang's lab). This bipedal molecular motor is able to "walk" consecutively on its own with a stride length of about 16 nm between each step, providing a maximum force output of around 2 to 3 pN. This measured force output is at a level which is near to naturally occurring molecular motors powering human muscles, indicating a reasonably efficient conversion of chemical energy to mechanical motion.
Prof. Wang said, "This study paves the way for the development of applications associated with translational artificial molecular motors which require the generation of forces. Examples include molecular robots and biomimicking artificial muscles. Separately, the single-molecule method established in this work is applicable to force measurement of many other artificial molecular motors with soft tracks."

They are setting us up to be the actual bipedal energy source!
Covid motive exposed.
Watch Rick and Morty, they have a problem with their energy source and need to enter an inner universe constructed by Rick to enslave a budding universe by exploiting them in the exact same manner described in this article. :>

Que in the woke crowd after that little "man-made" pho-pa.
Trans-made, Woman-made, Gay-made, Kool-Aid
Err...never mind.

So how do these differ from midi-chlorians?

convert chemical energy?
so like lineing pipes with this "slime" and then the slime takes some of the liquid (chemical energy) to pump ... err... move it thru the pipe? like straw with some black cramel sugar water and it "selfdrains" out one side?

Well, I suppose you could read all the links that were provided, and the links that those documents also include which explain it in far more technical detail. Just because you or I don't understand the details doesn't mean that nobody else understands it either.
