Summary of All Mechanisms

All of technology can be summarized to:

1. Bulk structures - dirt and wood
2. Metal and plastic - precise shapes.
3. 3D Printing - plastic, metal, and stone (ceramic, house concrete, mud)
4. Rotor - shaft, 2 bearings, and a coupler. All rotor heads.
5. Metal sheet, wire, tube - hot metal
6. Alloying - metal and plastic
7. Piston - linear motion. Engine, pump. Hydraulic, air, material.
8. Electric wire - induction for furnace or motor; or solenoid; or injector. Highest tech is high pressure injector.
9. Microcontroller and transistor - for timing. Controlling a 10kW motor with an Arduino.
