Space tower passenger pod

As if I don’t already have enough going on, I wanted to use the cardboard ring that’s left when I use all of the cloth tape as a model for a space tower passenger pod which is just big enough for spin gravity. The tube is 1⅜” across with a 1” inner diameter and ¾” deep. Scale this up to a 22 meter cylinder or ring with an inner diameter of 16 meters and 12 meters deep/tall, or 11 meters by 6 for a simple short can. At 6 rpm, that’s 11*22/7/10=242/7/10=~3.457 m/s, squared divided by radius 5.5 m is ~2.1 m/s^2, a bit more than lunar gravity, at your feet, that is; it falls off to ~1.4 m/s^2 at your head. Basically enough to notice but perhaps not worth giving people motion-sickness.

This is a 11 meter space 6 meters tall on the ground, about 35’ by 20’, a volume of a little over 500 m^3 for a mass of 16 tonnes at 3 tonnes per hundred m^3, with a surface area of about 400 m^2. Steel ¼’ thick, about 0.63 cm at nearly 8 g/cc, about 50 kg/m^2, about 20 tonnes for an estimated mass between 16 and twenty tonnes for structure. We could pack about 35 people in seats against the outer wall which becomes the floor under free fall spin. Give them a bit of room and we come to about 17 passengers. If we estimate a generous ~300 kg/peep for passenger mass, luggage, furnishings and life support, ~5 tonnes, brings us up to 25 tonnes. This is a nice number, plus 20% for everything else? Call it 30 tonnes, a couple tonnes per passenger. Thirty thousand kg to escape velocity of 11 km/s at (1.1*10^4)^2/2*3*10^4 comes out to a couple trillion joules, about half a million KW-hr worth of power at close to 100% efficiency, or ~$50,000 @ 10¢/KW-hr, so tickets run to $3,000 per passenger, less if power is cheaper and if it’s still the largest part of the ticket price.
