I agree that the current designs should continue. If electrode failure becomes a problem then other designs can be considered. I was trying to spark a conversation about other possibilities that may be improvements. A few months ago someone brought up the idea of two dpf units facing each other. That idea didn’t go anywhere. Essentially, that is what I was trying to depict with the pinch occurring in the space between the two dpf units.
An alternative is to use a single dpf with the electrodes designed to maintain the pinch outside of the central electrode.
