this is my favorite lately. the cable strung units offer a way out of the problem of radial gravity and large volume buildings. each unti can align itself to it's own local vertical.

A new try at the initial building style, along the length of the cylinder rather than around the circumference which became uncomfortable when crowded.

sketches influenced my reginald malcolmson's linear city.

Ten most common elements in our galaxy by mass, estimated spectroscopically[5] Z Element Parts per million
1 Hydrogen 739,000
2 Helium 240,000
8 Oxygen 10,400
6 Carbon 4,600
10 Neon 1,340
26 Iron 1,090
7 Nitrogen 960
14 Silicon 650
12 Magnesium 580
16 Sulfur 440

Hydrogen and helium are 74 and 24 percent of the mass of our galaxy.

scarcity:

By mass, human cells consist of 65-90% water (H2O), and a significant portion is composed of carbon-containing organic molecules. Oxygen therefore contributes a majority of a human body's mass, followed by carbon. 99% of the mass of the human body is made up of the six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

Element Percent by mass
Oxygen 65
Carbon 18
Hydrogen 10
Nitrogen 3
Calcium 1.5
Phosphorus 1.2
Potassium 0.2
Sulfur 0.2
Chlorine 0.2
Sodium 0.1
Magnesium 0.05
Iron, Cobalt, Copper, Zinc, Iodine <0.05 each
Selenium, Fluorine <0.01 each


hmmmm.
