i would not say its magnetic, i planned a plain simple reversed pulse of very high intensity tuned to a certain frequency to shake the covalent electron the reaction will occur near both electrodes but not actually at the electrodes...by near i mean nano or pico meters of distance... is the distance of the double layer which i dont remember now...
i believe meyer used the double layer capacitance of water instead which is pretty much high and therefore there is a lot of importance in analysis than the only physical capacitance
it takes a very small voltage to start leaking just about 1,24v so this is kind of the first limit of charge ability for accumulate...
when there is such voltage applied there is a region formed where there is a drop of 0,5v that forms an electric field of the intensity of 5000kv if i remember well because the drop occur in a very small length... any book for hydrogen fuel cell tech should have the right numbers
i wonder if this electric fields manipulation is all we have to do it would prove to be simple and stupid
