They are boats! The sailors are already used to the rocking of the sea. It's good for the plot too — you can have a dramatic tumble anytime you want. It also makes for unique visuals. | |

| May 16 at 5:33 | comment | added | Michael | @gs well, at least you have a nice big fan for air cooling ;) | |
| May 16 at 1:04 | comment | added | Kevin Kostlan | Lift fans are much less efficient than copters. So helicopter-levels of disk loading should be feasible once all extra mass is accounted for. | |

| May 15 at 18:15 | comment | added | g s | @SarahMesser and some turns into lots when you don't have an ocean or a river to use for heat rejection. | |
| May 15 at 17:38 | comment | added | Sarah Messer | Love the detailed answer; will just point out that SMR systems have some additional weight which might not be covered in the usual specs: cooling, turbines (to turn the heat into electricity) and radiation shielding, for example. The HPM in the diagram at en.wikipedia.org/wiki/Gen4_Energy is only a small portion of the overall system. Maybe some of that can be reused between reactors, or dropped from OP's design, or otherwise minimized via clever engineering... | |
