That would explain why rapid spinning films over a surface build up incredibly powerful static fields. It’s been observed that the contact surface area doesn’t seem to matter, and it’s easier to build up with greater velocity. It’s all about where the energy is going, and it’s into those imperfections. Cool
It’s not inaccurate. The electrons do “just move” but the energy transfer mechanism was unknown for static buildup. With enough kinetic energy (aka friction heat, I hate the concept of friction) the charges are going to move and collect easier, just like charging a battery. Just really tiny batteries
