Hydrogen Making Companies

When are fuel cell cars coming out?
I heard that car companies are making cars that run on water and the Hydrogen inside of it when will this be ready? How is it currently developing?
one may know that avery high voltage is discharged to earth through lightning.if it is possible to use this voltage to electrolyze water into Hydrogen and oxygen which can be used in fuel cells to power automobiles and others in future,whose waste will be pure water…isn’t it a better idea!!!
NO need for Hydrogen energy, watch this VIDEO!
