You get 2X *at best*. It's usually much lower than that. Now further
deduct for that atmosphere you're so proud of, dust, etc.

Correct me if I'm wrong... but doesn't light behave according to
inverse-square laws...? Since Mars is twice as far away (roughly)
from the sun as we are, doesn't that mean that solar energy is
one-quarter the intensity?

Or am I just plain confused? :-)
