Yes, it also struck me that way. As an offtopic aside, the Mars day/year slide ( http://style.org/visualized/images/weightofrain_34.jpg http://style.org/visualized/images/weightofrain_34.jpg ) made me think we should really build a "second home" (or vacation house, or mountain cabin). Perhaps mountain cabin is the appropriate metaphor. It's another 70 million km up the Sun's gravity well. If we take solar energy supply as a feasibility criterion, it's 43% of what we get on Earth.
