This is an interesting video showing the new Hyundai NEXO Hydrogen Fuel Cell powered car. Rubbish UK infrastructure at the moment (there's a filling station beside me), but 400 mile range with 5 minutes to refuel would work if there was sufficient filling stations.
The car looks quite nice too. I like the blind-spot cameras which come on when you indicate. They should be standard on every new car. More useful, in my opinion, than a reversing camera (I'd want both!).
