A video mirror system for a vehicle includes an interior rearview mirror assembly with an electrochromic reflective element having a front portion and a rear portion generally opposite the front portion. The cutter hub is rotatably driven and includes cutter blades mounted at a steep angle on the cutter hub and move along the face of the die plate to cut the extruded strands into pellets. Source and drain electrodes are separated from the photoelectric material by a smaller gap such that photoelectrons created when a photon impinges on the photoelectric material it will release a single electron under a bias to the drain electrode, rather than directly to the gate electrode. The hairbrush bristles can have substantially equal lengths such that the outer peripheral portions of the plurality of hairbrush bristles defines an hourglass shape. Preferably, the capacitor is assembled by constructing a first portion and a second portion, the first portion comprising the cathode and an extra thickness of solid ionomer on its inner surface, the second portion comprising the anode and an extra thickness of solid ionomer on its inner surface. The return flow line is then disconnected from the pig after sufficient deposit removal and retrieved from the return flow line.
