That was my initial thought as well. The vids on the sites show a vigorous amount of bubbling, and they use coiled stainless steel wires along with electrolyte added to the water (sodium hydroxide) but that didn't seem to be enough to me, though the lye does increase the rate of the reaction quite a bit.
Oh, and I read several criticisms of it that when you electrolyze w/ stainless steel, you separate the chromium from the steel and that could be hazardous. Some of the chromium is in the form of Cr(IV), which is very carcinogenic when inhaled. This might be coming out of the tailpipe of vehicles running these jar systems, so don't tailgate anyone who uses one until some testing is done! Most chromium evolved is Cr(III) which is far less toxic and is an essential nutrient in small amounts, though can cause asthma attacks in susceptible individuals when inhaled.
The water left in the jar may in fact be classifiable as hazardous waste, and if dumped down a drain could pollute groundwater. Cr(IV) contamination of groundwater was the issue that Erin Brockovich fought PG&E over in the now-famous class action lawsuit that was settled for $333 million.
