Re: Hydrogen cells and cold weather
If your thinking of running an HHO system which is basically H2O with a potassium elecrolyte it should be good to -15*F but a type of antifreeze may also be warranted....however placing propolyne glycol or ethylene glycol thru an electrolysis process and then inducting it into the engine to be burned is NOT a good idea. DON'T use regular antifreeze. However you can use isopropyl alcohol (rubbing alcohol). I'd check with the manufacturer of the unit for advice and concentration.
