Legend

AU = Abundant / Universal elements (CHON + Si, Al, Fe, Ca, Mg, Na, K + S, P, Cl + Cu, Zn)

RS = Rare / Strategic elements (Cr, Ni, Ti, Mn, B, F, Li + Nd/Pr/Dy, Co, W, Ag, Au, Ga, As…)

Score: 0–5 (5 = critical, 0 = negligible)

Item (g1)	AU (elements + score)	RS (elements + score)	Notes (one line)
Shelter	Si,O,Al,Ca,Fe,Mg,C,H (5)	Cr,Ni,Ti,B (3)	Concrete/glass/ceramics + steel; alloys if available
Structured elementary particles (material structures)	C,H,O,N,Si,Fe,Al (5)	Ti,Cr,Ni,B (2)	Robust structures without high tech
Clothes	C,H,O,N,S (5)	F,Ti (2)	Fibers + treatments; F for high-performance membranes
Toilet	Si,O,Al,Ca,Fe,C,H (5)	Cr,Ni,Cu (3)	Ceramics + plumbing; stainless steel preferred
Cleaner	H,O,Na,Cl,C,S (5)	F,P (2)	Bases/salts/solvents; P for advanced detergents
Transportation	Fe,Al,Si,C,O,Cu (5)	Ni,Cr,Ti,Mn,Li (4)	Alloys + wiring; Li for electric systems
Defense	Fe,C,Al,Si (4)	Ti,Cr,Ni,W (4)	W useful for high density (rare)
Help (tools/basic care)	Fe,C,H,O,N,Ca,Na,Cl (5)	Cu,Zn,Ag (2)	Hygiene + tools; Ag optional antimicrobial
Information transducer	Si,O,Al,Fe,C,Cu (4)	B,Ga (4)	Sensors/actuators need dopants/semiconductors
Information processing	Si,O,Al,C,Cu (4)	B,P,As,Ga (5)	Modern computing = doping + fine processes
Data storage (disks/books)	C,H,O (paper), Fe (magnetic), Si,O (glass) (4)	Co,Ni,Nd (4)	High-end magnetic storage needs Co/Ni + Nd magnets
Information seeker (search engine)	Si,Al,Cu,C (4)	Li,Ni,Co,Nd (4)	Compute + energy + interconnects
Information transmitter	Cu,Al,Si,O (5)	Ag,Au (2)	Cu/Al + SiO2 fiber sufficient; nobles for reliability
Stimulants (broad sense)	C,H,O,N,S,P (5)	— (0)	Organic chemistry + nutrition; rares add little
Leisure	C,H,O,N,Si,Fe,Al (4)	Cu,Li,Nd (2)	Simple materials; electronics optional
Training	C,H,O,N,Si (4)	Cu,Li (2)	Media + tools; electronics optional
Cutlery	Fe,C (5)	Cr,Ni (4)	Stainless steel is a major practical upgrade
Mattress	C,H,O,N (5)	Si (1)	Foams/latex/fibers; silicones optional
Table (furniture)	C,H,O (wood/polymers) or Fe/Al or Si,O (glass) (5)	Cr,Ni,Ti (1)	Easily built with abundant elements
Chair	C,H,O or Fe/Al (5)	Ti,Cr (1)	Same: abundants are sufficient

Rare/Strategic elements (RS) – where to source (countries)

Legend

• AU = Abundant/Universal (easy)
• RS = Rare/Strategic (hard / concentrated supply)

RS element	Main use (why you care)	Main sourcing countries (today)
Cr (Chromium)	Stainless / corrosion resistance	South Africa (dominant); Kazakhstan, India, Turkey (notable)
Ni (Nickel)	Stainless + batteries	Indonesia (dominant); Philippines, Russia, Canada, Australia, New Caledonia, Brazil
Ti (Titanium minerals: ilmenite/rutile)	Light strong alloys, durable structures	China; Mozambique; South Africa; Australia; Canada; India
Mn (Manganese)	Steelmaking + some battery chemistries	South Africa (largest); Gabon; Australia; China; India
B (Boron)	Glass/ceramics; steel/glass modifiers	Turkey (very large); USA; Argentina; Chile; Russia; China
F (Fluorspar → fluorochemicals)	HF/fluoropolymers; batteries; refrigerants	China (largest); Mexico; Mongolia; South Africa; Vietnam
Li (Lithium)	Batteries / energy storage	Australia; Chile; Argentina; China; Zimbabwe; Canada; Brazil
Co (Cobalt)	Batteries / high-performance alloys	DR Congo (mining dominant); Indonesia (growing); Russia, Australia, Philippines, Cuba (notable); refining largely China
W (Tungsten)	High density + hardness (tools/defense)	China (dominant); Vietnam; Russia; Rwanda; Spain; Austria; Bolivia; Portugal
Ga (Gallium)	RF/power electronics (hard bottleneck)	China (overwhelming); Japan, South Korea, Russia (secondary)
Nd/Pr/Dy (Rare earths for magnets)	Motors/actuators/sensors; “high torque density”	China (largest); Australia; USA; Myanmar (notable); processing often China-centric

Minimal RS subsets (pick what you build)

RS for “durable everyday civilization” (shelter + toilet + tools + transport)

• Cr + Ni (stainless)
• Ti (light/strong)
• Mn (steel)
• B (glass/steel modifier)

RS for “electronics-heavy” (processing + transducer + transmitter + seeker)

• Ga (critical)
• Nd/Pr/Dy (magnets)
• Li (batteries)
• Co (some chemistries)
• (plus Cu from AU for wiring)

RS for “extreme density/hardness”

• W
