Well I presume that the closest approach to the ideal capacitor is
a pair of parallel plates in a vacuum! A bit bulky for anything more

Hey, what limits the voltage on a vacuum-plate capacitor? I should totally
know this, but above a certain voltage for a given separation, is there
any kind of breakdown?
