He's on to something this Elon Musk. If you look at the freaking huge version of the starship/booster, you start getting economies of scale.
Here's what I mean.
Doubling the diameter from 9 meters to 18 meters gives 10 times as much payload capacity. Total liftoff mass is about 2 and a half times. There is a distinct advantage to going really big. By the way, let's look at another ratio for this thing to see the efficiency gained. Note that the ratio to payload and liftoff mass. For the first version of Starship, it is 2% of the total liftoff mass. The second more massive version of Starship will have a ratio of 1/12th or 8% roughly. You triple the payload fraction when you double the size. It really pays off.
With that, I turn it over to the video.
