Damn the torpedoes (and Teslas)! Two of Japan's biggest automakers are about to make sizable wagers on a different kind of clean fuel tech: hydrogen power. Toyota will launch the $57,500 Mirai fuel cell vehicle (FCV, above) next year, while hydrogen veteran Honda will out a model in 2016. But wait, aren't EVs the last word in green cars? Fuel cell cars are EVs, in a way, but you can fill one up with hydrogen in five minutes rather than waiting hours for a charge. The only way to do that in an electric vehicle (EV) is by swapping the entire battery. So why is there exactly one production FCV available to buy today, but EVs everywhere? That's a tale of efficiency, fuel, pollution and politics.
