A while back I thought of an issue with parallel charged plates. Imagine this: a set of opposite charged resistive plates with holes in the center. In theory, there is a finite amount of energy required to push a positive charged particle through the hole in the positive plate (in theory it should be comparatively small). However, due to the relatively uniform electric field in between the plates, the charged particle could garner up to an infinite amount of kinetic energy if the distance is infinite. This creates the issue that it takes a set, finite energy to push the particle into the plate, but, depending on the distance, one could get more energy out than in. While work has to be put into separate the plates, the potential energy of the plates doesn't change if a charged particle enters and exists the system. Even if heat is created by the force on the plates, that doesn't change their charge, and thereby the potential.
I have attached a document to this post which gives a more specific example as well as an image to clarify the problem. I have since run out of people to ask as no seems to be able to figure out what specifically is conceptually the source of the energy.
