Glenn did not run his cell at 210 degrees F, nor did he use tap water. Thermal runaway is not going to raise the water temperature to boiling in most cases because it cannot, the evaporating water vapor coming off cools the liquid before it can actually boil. Only a super innefficient cell running on way too much voltage/current will actually reach boiling. But irregardless, anything over 180 F is going to put out so much water vapor to be useless for anything other than a hot vapor water injection system.
Thermal runaway as referred to in electrolysis systems is the electrolyte starting out cool and getting hotter and hotter from the increasing current flow. If unchecked, it eventually will reach a point where it will stabalize, but that is going to be way to hot to run efficiently and it will put out loads of excess hot water vapor. In many cases it will reach meltdown temperature of the container used to hold the electrolyte, hence thermal runaway until meltdown. We're not talking nuclear meltdown here, we are talking about thermal melting of the container.
