re: Griffin tries to pitch "lifeboat Mars"
Doug, as I have told you repeatedly before, I am not the person best equiped to explain this to anyone. That said, in point of fact the power requirements and platform stability both require the use of the surface of the Moon to provide adequate (which is to say optimal) capabilities. The surface of the Earth does not, LEO does not, L1 does not.
I know you have trouble with that conclusion, but please raise your points by writing tha Cambridge Conference, and someone more qualified than myself will clarify it for you.
