comment Where's the energy in a boosted capacitor?
@JerrySchirmer Outside the capacitor, the EM field in the rest frame is zero. When you boost zero, you still get zero.

comment Why does the speed of light $c$ have the value it does?
Well, that's one way of thinking of it, but it hardly means that what I said is wrong. One can also simply define a new unit of length, called the "clunk", and a new unit of mass, called the lump, and choose them such that $\hbar = 1 lump*clunk^2/sec$. At that point, we realize that if we have some relationship between clunks and seconds, say $c = 1 clunk/sec$, then we can simply call seconds, clunks, and lumps all by the same name and say that $c = \hbar =1$. There's no problem with it; it's not wrong.

Yes, it is. Unfortunately, I find your claim that "equations in physics do not have units" too cryptic to reply to further. I don't understand what you think you're replying to or why you think this statement is relevant, much less what it means.
