I think fuel cells is what started me on my rant about Rio this morning. I had just read "Madza goes hummm" in the WSJ and this jumped out at me www.autonews.com/apps/pbcs.dll/article?AID=/20120625/COPY01/306259791/1117 Mazda is also planning to introduce an electric car next year using hydrogen to fuel the rotary engine and generate power for the car's battery. Fear? Yes. Did I bet on the wrong horse? Time will tell, but "Fuel Cell" sure seems to be popping up just about everywhere you look.
