Whole Wheat: The Saturn V looks on your shenanigans and says "meh".

The Saturn V had 5  engines with 1.5 million lbs of thrust each for a total of 7.5 million lbs of thrust. SpaceX is planning a much more efficient rocket that can theoretically be refilled at Mars using methane which can be produced on Mars that will be 9 engines with 1 million lbs of thrust each for a total of 9 million lbs of thrust.  Its higher ISP of 363 compared to F-1s in Saturn V of 303  (ISP is a measure of fuel efficiency).
So its quite possible this rocket will have a higher thrust to weight ratio before payload.

I'm glad for people like Elon Musk and Burt Rutan.  Hell, I'll even say Richard Branson... but not quite as enthusiastically.

Man I should boot up Kerbal. I was designing a mission to Duna and got frustrated at my efforts to dock modules together in orbit and put the game aside for a while.
