run your car on water

hydrogen is really flammable, and can kill you if you don't know what your doing.
this was bob lazar, that same UFO guy you heard about for the past 30 some odd years.
but he's right, you can easily create it, storing it in a car is a bad idea and most ppl don't attempt this for that reason.

i don't know why bob is saying it's completely safe, maybe it's his system and how he set it up, but in most cases when i have seen folks convert their vehicle with this stuff being used, almost nobody ever does straight up hydrogen and only do it on demand, which means it's created on-demand and never stored because if the tank is breaks and is exposed to a spark, your fucked.
