Perpetual motion machine. The car's battery is used to disassociate 2-H2O into 2-H2 and 1-O2. You then inject this mixture into your car, which charges the battery and somehow gives you more energy back than you had to start with. Sorry but you just violated a few laws of thermodynamics and caused several of my Berzerkeley professors to spin in their graves (Glenn Seaborg et al).
