Has anyone tried using a separate battery to run the HHO generator rather than running it off the car's electrical system?
Reason I ask is that it would make for a more efficient use of gasoline. A 180 amp hour deep cycle battery could run a 30 amp HHO system for 50 hours. I would suggest recharging the battery nightly, however. The battery could be charged at home overnight. I would think that the cost of charging the battery would be less than the fuel used to generate the needed electricity while driving.
What do you guys think? Would it make enough difference to notice?
