Inclined Planes are 100 meters wide, spiral ramps are 15 metres wide (I've converted my Warden to metric).
But to accomplish 200, 400 and 800 metre rises, Inclined Planes would have to be either really long straights or switch-backs.
The same rise for a spiral ramp would be a ridiculous distance to walk. So what, grav sleds in them too? Or maybe low- or no-grav rope tows along the walls? Futurama-style vacc-tubes? That corkscrew would be murder if you had vertigo.
I have seen that cutaway (I'm eagerly awaiting my Goodman gear). But the radical compression in that illo of ship features threw me 'til your mention of it. Now looking at it again I've come up with some ideas. Thanks.
