Sure two electrons "trapped in the solid" have mass-energy,
relative to a system at rest to be,

M = 2*mass(electron) + (charge)^2/r == 2m + q^2/r

where that last term is electrostatic potential energy.

In a relatively moving frame, SR tells us the mass of that
charge system is

M' = 2m' + q^2/r' .

It's often written as M' =M*g , g=1/(1-v^2) so that,

m' = m*g and r' = ct' = r/g = ct/g.

Where SR is concerned, I think it's a 1st class unification
to provide an understanding of how, inertia increases
with velocity is smoothly in accord with electromagnetism.

He certainly has an excessive occupation with irrelevant and
un-enlightening detail.
