I have read some articles claiming that you can build a device for less than $100 that will electrically separate “brown gas” (HHO) from water to supplemental gasoline and virtually double your miles per gallon. Seems too good to be true, so it probably is not.
Does anyone know for sure?
EVERYONE knows for sure. The hucksters who push this scam laugh as they take people’s money, and their sucker customers find out afterwards – when it’s too late.
