Scientists at North Carolina State University have discovered a nanoscale method for extracting hydrogen from water that requires only half the
energy of current hydrogen production methods.

That's pretty damn cool. We still have to deal with all the problems of
using the hydrogen, such as storing it, or using the fuel
efficiently, but, hey, gotta start at the basics.
Still, in the end, it just means you might as well spend more money on CNT since either way they're useful.
