Is the cost to doubling the width of starship proportional to pizza?
- AstralStorm 6y agoNo, much higher, because of extra engines and more plumbing. Starship is already pretty marginal of an upper stage and it's fired early. More marginal than old Space Shuttle, but cheaper to refurbish.
- rbanffy 6y agoOTOH, the weight of the rocket grows mostly linearly (it's essentially a skin around propellants), the number of engines grows with the square of the diameter and the fuel volume grows at a cubic rate, so the engines can burn for longer (at some point, aerospike engines will become practical).

- 6pac3rings 6y agoI was wanting to compare the industrial scale cost of doubling the width of a pizza to doubling the width of the cross section of a starship. Your entitled to you're opinion
