I have been going back and forth with a guy from Australia. In his videos he claims to be making 4-5 liters of HHO at 12 amps. You can clearly see in his video that he is only putting out maybe 1 LPM, but for some reason he insists that he is putting out much more because he is using a professional flow meter. Please check out this video and read the comments. He is very arrogant and says that we "Americans" are a bunch of morons basically, and that he is eons ahead of us. I am begging everyone here to pounce on this guy, PLEASE!
