I didn't look at this much because I noticed right off there is a mistake with regard to the fringe force on the edge of a dielectric slab that is well within the plates. The E field lines are not vertical at the slab edge as shown, but rather bend inwards toward the dielectric and there is thus a net force that draws that edge in a direction so as to maximize the amount of dielectric between the plates. There are various electrostatic motors based on this principle which have special application to nano-machines. Regards, Horace Heffner
