I have been away from this forums for a few months. I am confused about this dry cell and how it works. I am guessing the wet cell were the first hho systems made where as you take the plates, put them in the box or tube, and add the lye and water together. I see that the dry cells push the water and such through the plates. How does this work and what are the benefits for it? Does it produce more hho with less amps? Also what is MMW.
