    Rob, could you elaborate somewhat?  I'm interested 
    enough in this that a while back I wrote up a little 
    Web page with some speculations:
    Two of the obvious factors are 50% daylight and 70% 
    ocean (and nn% of land uninhabited), and there's the 
    Earth's equatorial bulge (and maybe its oblateness),
    and of course the percentage of cloud cover (which I 
    don't know).  What is the percentage of the Earth's
    surface within the tropics (+/- 23.5 degrees)?  I 
    don't know how to do that math.  So I would like to 
    learn more of the technicalities on this topic.
