Water powered cars?

I'm sorry if somebody has already posted something about this, but it's important. H2O powered cars are real, and here. Amazing right? BMW has a model already and Hyunda is starting to make them. http://waterpoweredcar.com/ this website has info on them, and I think it is a great idea, and all those fossil fuels we're burning will no longer output harmfull emmisions into our atmostphere, which is depleting our ozone layer. Simple for us, better for the enviroment. I don't believe there are any downsides to this new h2o car. It's not just a dream anymore.
