well......its somthing that has been tested. when you say circuit your being very general, but its enough to start talking.
IF stan meyer wasnt a fluke, and was telling the truth (which i beleive he was) THEN the answer is yes.
some others have also built circuits to drive their electrolysers, and seen realy great results. such as Bob Boyce. he's around on the forum quite a bit, and holds allot of good info... his circuit uses harmonics...
for more on bob's circuit, i suggest u read this, so that he doesnt have to repeat any Q's that you may ask him.
