cold weather and hho generator

[wapiti_j]

I have been researching the HHO generators. I have not found information on what to do with sub-freezing temperatures. Does anyone have any experience with the generator and cold temps?

With a sodium hydroxide solution, which is what baking soda becomes, in low concentrations 1-20% or thereabouts, the freezing point drops to below -20C... but it clibs rapidly back above 0C at 30% concentration by weight. Therefore the concentration should be carefully maintained at 20% or a little lower for best freeze resistance.

I have done some work on that here:

In a home freezer at -5F I found that the cells do not hard freeze, but rather become sort of a slush. I did not break the glass jars. You can add a little ethyl or iso alcohol, but avoid ethylene glycol
