    The latest Science reports a substantially improved catalyst for
    light-induced splitting of water. Addition of carbon to the
    previously known titanium oxide catalyst yielded 8.5 percent rather
    than 1 percent efficiency. Ten percent is the Department of Energy
    estimate for commercial viability, though the energy to make the
    stuff and ease of large-scale production were not discussed in the
    summary. If further work increases the efficiency of this effort, it
    could provide hydrogen as a viable replacement for some uses of
    petroleum-derived fuels.

    Despite the favorable press that this gets as being more ecologically
    firendly, water vapor is a greenhouse gas. However, buring hydrogen
    probably will not have more effect than burning similar amounts of
