I won't give away the plot, but a key, if clunky, exchange between two baddies towards the end of the new Bond film, Quantum of Solace, goes:
Baddie #1: What's that sound?
Baddie #2: Oh, it must be the fuel cells - this whole place runs on them.
Baddie #1: Sounds unstable!
And guess what, ten minutes later the 'whole place' goes up as the 'unstable fuel cells' blow, creating fireballs left, right and centre. This is the technology that has been successfully and safely installed in schools and other safety critical applications and could form a key part of a sustainable future. The fuel cell industry will not be terribly pleased with how they have been portrayed. And quite rightly.
Oh, if you're wondering, the film's pretty good, but not as good as Casino Royale.
