    This isn't a new story, although that particular item may be recent. But
    there's another way to convert solar energy into hydrogen, which is to use
    the temperature difference between surface and deep water at the tropics,
    and produce hydrogen. Since the amount of solar energy arriving each day
    over tropical oceans vastly exceeds the world's energy use for the
    foreseeable future, the potential is huge. The best part is that the ocean
    acts as the collector, so you don't need huge solar arrays like you would
    with this technology. In addition, the mixing of the water would increase
    the amount of biological activity in a part of the ocean that's quite
    sterile.

    The downside is that one would have to maintain huge floating platforms,
    which would need to be stabilized against wind and current to keep them out
    of shipping lanes, from running aground etc. But not too difficult.
