Colin! If you are asking about the CRE approach (?), the answer is Yes, but!, CRE does have some limitations and those rap around the difference in AC and DC. As most will agree a capacitor is great for passing AC yet is a great storage device for DC. The CRE uses a capacitor in series with the charging (power source) to the electrolyzer and as such you will see the normal charge, discharge curve of the cap. Yet, during the electrolysis process when one stops the current flow by removing the source, the action in the cell does not stop, it will continue for some time (depending on plate type, spacing and if AC or DC is being applied). The original CRE's used a relay and switched about 0.25 Hz, the current versions use MOSFets and run 600 Hz. Solid state CRE's run at 50% +/-20%(depends on electrolyte) and on average show 135-180% over the sane input using filtered DC. The limitation's) is (are) proper selection and matching of cell structure (plate spacing and material), electrolyte, desired gas output and capacitor size and switch frequency. For high production cells it is not uncommon that you could be using 1 Farad or more, yet with split cell construction (where produced gas is combined) you could obtain the same output with say 5 smaller units with each having 1uf cap at a freq of 15,895 Hz. Please don't confuse what is stated as being some magic number tied to any other way out claim or idea, the figure I am stating are from working systems of various configuration which have different construction parms.
Backing up some, the AC/DC diff comes into play in that the cell sustains evolution when power is removed, that in effect is the same as a reduced resistance when the pulses are passed through the cell. Should the pulse freq be below the cutoff point of the self sustained evolution (due to ion build up) then production will drop off sharply. Currently the StifflerScientifc lab had a simple yet effective CRE running that gets around the ion cloud around the electrodes. This is seem in a normal cell as the current rises at the start to a max point, then declines to the operational point. The new CRE allows the production to stay at it highest point by switching between a special electrode configuration. CRE makes use of both the AC component and the DC (may will regurgitate over this statement) yet it is proven by many systems on the market today that pulsing does indeed work better (for a number of reasons) than steady state DC (NO Stanley Meyer theory here). Sorry for a simple answer being so long,yet I have worked with many CRE designs and they are worth looking into.
