The challenge to the "hydrogen economy" folks is to explain why if you
have the energy to liberate the hydrogen in the first place, why not just

refinery, distribute it to retailers, and so forth, you'd "throw away" all
that just to gas up the old suburbedition and drive around with your buddy

technology exists to make hydrogen power economically feasible when he
hasn't done any such thing. But that's not important right now, because all
I asked is what, if anything, ever became of this:
