Very cool, did not know that! I also heard that many that tried to replicate his technology would get stuck in different 'dead ends' but that one aspect that is underestimated, it the role of sound/vibration to help the gas production, perhaps not just in finding the ideal resonant frequency, but also to have the sound aid the bubbles of gas to dislodge from the cells making it. Ohmasa from Japan has some fascinating developments, such as the ability to produce and STORE the case in cylinders, but also to clarify that sound is one factor that heavily influences gas production. I'll probably have to watch it again, but I chose NOT to include hours of Stan Meyers lectures since they can be a bit dry and may intentionally include information to veil underpinnings of the technology while he was alive. But that's another Week on youtube :/ too technical for me. But I had heard something to that effect before, thanks Hive account@dayoneness :) Apparently, the gas is implosive when in balance (between the ratio of hydrogen and oxygen) and explosive when that ratio is off by 5% or more. Maybe that was the kind of thing he had to fiddle with for burn rate optimization.... ?
