Many people have over doubled their mileage, get more power, & produce much less pollution because they have a hydrogen generator installed on their vehicle.  When enough people do this we will start exporting oil again!  If one makes their own, they can do so for much less than $100.00!  It is easy!  I have one on my car, as many others.  I plan to also make & install a gasoline vaporizer & disable the fuel pump so the fuel injectors cannot work & increase the hho gas greatly.  I hope to get OVER DOUBLE MY MPG to over 80 mpg.  Why continue to "feed" our rich enemy needlessly?
