That sock is converted into pure electrostatic spin. Not to mention lint.

That harkens back to a discussion a few years back in which I hypothesized the existence of a gyro-rotational Black Hole inside of clothes dryers, that swallowed stray socks, and led via a worm-hole to the Planet of Lint...... I'm still waiting to hear from the Nobel Committee on when I can expect my nomination to come thru....

I just printed the article and it looks like they have three spheres in an asymetrical configuration. They put a potential on one sphere and the others move. The asymetrical arrangement causes the torque.

There isn't anything about QM spin; it's all electrostatic.
