Middle Tech / Midtech

Middle Tech is a term used for the characteristic technologies of Old Earth from the Industrial Age to the late Information Age. Though powerful, these technologies have high energy and material requirements in proportion to their outputs, and can cause resource exhaustion and environmental degradation if the mechosystem is not carefully managed to capture and recycle its products and its abundant wastes. Middle tech societies may take a variety of forms, but the diversity of middle tech societies on any one world or megahab may actually be small due to the levelling effect of rapid local transportation and communication.

Characteristic midtech includes nonsentient computers, interactive media, presentient and subturingrade expert systems, network architecture, basic biotech with crude gengineering, nuclear fission, chemical rocket engines, electronics, artificial dyes and fertilisers, artificial fibres, fusion weapons, crude solar cells, antibiotics and other synthetic drugs, inexpensive refining of raw materials, basic automation, and mechanised agriculture.

Though of course midtech is widespread as a component in higher tech societies, exclusively midtech societies are vanishingly rare. Midtech lacks the stability of both higher and lower tech levels, so such regions either evolve to high tech societies or slip down to a more sustainable lowtech level. Nevertheless, midtech level artifacts may be popular among modosophonts in higher tech societies who prefer items that have powerful effects but are easy to operate and repair.

  • ACER (aka 'Boom Bullets')  - Text by Luke Campbell, Mike Miller, and Todd Drashner
    Personal weapons system that operates by firing small nuclear explosive shells.
  • Adaptive Mimetic Materials  - Text by John B
    A piece of matter designed to gather specific biometric traits of a being and store them for later recovery or broadcast/narrowcast to a dedicated recorder. The most common is the adaptive mimetic material handle, which samples both palm print, finger prints, bio-electrical signatures, and sweat chemistry amongst bionts. With careful design, such materials can gather similar abiometric data from cyborgs and vecs, mapping the specific frequencies released by actuators, relative actuator strength, precise beam lengths, etc. This is often used as a cheap security measure.
