I was browsing post, and see you guys talking about car run on water.
So i decided to post. I am mechanic and i put Hydrogen kit on my car.
Truth1- it save gas some maybe 25% milage increase if you follow instration.
Truth2- get more power, my car accerate up to 45 mile per hour without pressing gas pedal

Well i had to replace brake,cos i got additional power and wear out brake simply could not take it.
Truth3- Better emmission, my friend's surbarban was miss firing and unburn gasoline was coming out tale pipe, not anymore
Truth4-Man engine oil is not getting dirty at all, so I forgo oil change till i see dirty oil
Untruth--devise made by those e-book won't make your car run on water 100%, just boost performance by cleaning inside engine and add some HHO
I saw news about 100 % water for gas car in Japan, some company is making it.
But for now,for your existing car,before gas hit $5, go to mechanic991.wetpaint.com and look completely assembled kit.
This one is cheapest around(basic)
