Stop flow of HHO

by Geoff
(Metairie, LA, USA)

What occurs if the system runs out of distilled water? Does this harm the unit? Does the HHO Chip and/or the system adapt, putting the engine back into its normal running condition, fuel economy, etc.?

Can it be turned off as desired or is it strictly on and off with the car? Not that we'd want to, but for exampe, if we run out of water.
