Ok that is even worse. This will not work with full strength electrolyte. 4.6 volts per cell/pair/plate. The amps are split by 2. 4 groups of 7 plates each +NN-NN+. They must be in series?? If you changed each group to -NNNNN+ and wired the groups in series (4 stacks) you would bring the voltage down to 2.3 and divide the amps by 4 and be able to run full strength electrolyte in the winter and make much better gas in the summer. The gas production will go down but moisture is all that is going down. This will show you that in some cases when the MMW goes down it is a good thing. It is not how much gas but volume of moisture in the gas that distorts the MMW's. A very poor reactor could have a 12 MMW but be producing mostly moisture. You might not be able to even see the moisture.

It might not be physically practical to make the suggested changes with that design. I suspect you are way over driving the plates. .5 amps max per square inch of active area. How big is each disk and how wide is the gaskets or are they O rings?

The reason this design requires a cooling coil is because it is being over driven wasting energy in making heat and not the most efficient reactor. Make sure you are using a very good bubbler system or your throttle body and other components will get eaten up. It shows some interesting design thought on the makers part and maybe with some changes be OK.
