Water powered cell phones?

There are a lot of really smart people in this world.  Article’s like this one, suggest to me that I don’t fit into that category.  Engineers at Samsung claim they’re on track to put a cell phone on the market in the next couple of years that will be powered, essential, by water.  According to the article the water would react with metal to create hydrogen, which would then create the needed power to run the cell phone.  I’m sure someone will find a technological hurdle between now and when they want to have it on the market, but the idea is pretty sweet.  Maybe the research that has gone into this cell technology could be used in other areas to produce hydrogen power.
