Technology level 3

Technology level 3 is the fourth of the Technology level classifications. The defining characteristics of a society having reached TL–3 the development of the external combustion engine, a steam engine, to drive all manner of industries and vehicles. The expansion of availability of power provided by these engines drives an expansion mass production and manufacturing.

In terms of classification TL–3 is the Technological Period of Ur-Tech, the initial planetary bound cycle of development. It also occurs within the Technological Epoch know as the Tool Making Epoch.

Theoretical Technologies

Physical Science

Laws of motion

Engineering by math

Material Science / Manufacturing

Steel as structural material - Large scale production of steel allow use as a structural material for railroads, ship building, and structures.

Biological Science

Theory of evolution

Germ theory of disease

Cultural Science

Democracy - The idea of people being able to decided both who will rule them, and the laws under which they will live.

Quality of Life Technologies

Energy

Steam engines - An external combustion engine.

Primitive batteries - Chemistry to produce electricity.

Information

Communications

Photography - Chemistry to permanently capture images

Telegraphy - Use of electricity to transmit information over copper lines.

Medicine / Life sciences

Surgery -

Environment

Cement structures - The ability to construct reinforced concrete structures of impressive size, including buildings, dams, and other constructions.

Transportation Technologies

Land transportation

Extensive roads - The desire for transportation over land drive the ability to construct road for smoother travel.

Railroads - The construction of steam powered trains running on steel rails.

Water

Steam powered ships

Air

Hot air balloons

Military Technologies

Weapon developments are largely refinements of TL–2 designs, including such features as rifled barrels and elongated projectiles for accuracy and ballistic performance, early experimentation with impact-sensitive compounds as propellant igniters, very crude telescopic sights, and repeating weapons such as revolvers.

By the latter half of this period, almost every soldier would have a rifled single shot muzzle-loading weapon, with a detachable bayonet for melee use if there was insufficient time to reload. Artillery science is slightly more advanced, and crude exploding projectiles are in use by the end of tech level 3, as are are occasionally seen, but are generally inaccurate. They have the advantage of being able to carry a long range explosive payload without the recoil and mass of a regular cannon.
