gotcha. i saw something at the detroit auto show like 4 or 5 years ago, and it there was an exhibit that mentioned fuel cells for cars. between new info since then, my memory, and how much attention i actually paid to it, i could easily have misunderstood it... as it is, i've always thought of hydrogen only in terms of powering cars, so that would make it more of a storage medium rather than a source, i've never really differentiated between the two of them. my bad.
