Electronics
Joule Thief
- extract the last bit of energy from a 1.5 VDC cell to light a LED with this simple circuit
Supercapacitor
- Capacitors rated in Farads, not MICRO-Farads. Extreme capacity, battery replacement, almost unlimited charge cycles.
Arduino
- Microcontroller / CPU with imaginative uses
ESP8266 - Wi-Fi Microcontroller -simpolifies Arduino interface for IoT

Ceramics
Blades
- Zirconia blades rated 8.5 MOH opposed to steel at 6.5 MOH. Sharper, longer but more brittle
Fire Starter - Zirconia scraper superior to hardened steel.

Plastics

Kevlar
Dyneema, Spectra, etc. - Ultra High Molecular Weight Polymer (UHMWP) - Lighter, stronger than steel
Sugru / self vulcanizing Silicone tape - Silicone based self vulcanizing putty and tape
Polymorph / FORMcard - Low melting point thermoplastic polyester (160 F / 60 C degrees)' moldable by hand.

Magnetics / Rare Earth
Neodymium magnet
- Ultra strong Rare Earth magnets
Ferrocerium - Rare Earth misch metal used for "flints" and sparkers
