That doesn't mean it's not solvable. Throw enough time and money into it, someone's bound to come up with a solution. I read somewhere that the Gov't has allocated somewhere around $130m this year to do fuel cell research. $130m! Compare that to the billions we spent on the war to "protect" our oil "rights". There's no doubt in my mind that if the Gov't put as much zeal into developing alternative fuel sources, the problem would be solved.
