This article brought to mind the Stanley Meyer lore from many years ago. That may sound like an odd connection. It is the double layer connection ,,,
Although deceased for several decades, Meyer was a contentious figure in so called "water fuel" electrolysis, with a cult-like following even today. (mostly in Florida :-) The niche water-fuel field is still active, believe it or not, despite lack of commercial devices -- yet If there was any magic to Meyers design it probably related to optimizing the double layer - which is not all that well understood today. Note: Meyer's close electrode spacing and low salt, etc. and massive gas flow. Yet I'm skeptical of most of it - but will admit seeing results from Fast Freddy's Meyer cell which were great (but less than what would be needed to match his claims)... and so it is no surprise that many considered Stan to be well...either a martyr or somewhat less than honest. Yup. A persistent theme in alternative energy remains egoist inventors who find something interesting but can't take it further on their own. Apologies for the rant <g> .
