-====== SciFi Technology =====
-Contained here are some notes on the sort of technology available in a **Yags SciFi** setting.
-===== Space Drives =====
-Most of the following discussions are about //reaction drives// - those that work by throwing something out the back to push a space craft forwards. All require 'fuel' (actually, reaction mass, but it's the same thing for chemical rockets and fuel is easier to write), of which any vehicle will have a finite supply. This means that any reaction drive will have a maximum speed - though it can keep on accelerating, eventually it runs out of fuel. For spacecraft, this is generally known as **Delta V (dV)** - the maximum change in velocity possible.
-A ship with a //Delta V// of 20km/s could accelerate up to 5km/s in one direction, coast for a bit, then turn around and decelerate by 5km/s to come to a stop, for a total of 10km/s. It then has enough fuel to accelerate back up to 5km/s back towards home and stop again using up the last of its fuel. Though it could get up to 20km/s by burning all its fuel, doing so would leave it with no more fuel to stop or manoeuvre. A missile might do this, but a space craft with crew on board probably wouldn't.
-==== Chemical Rockets (TL 6) ====
-//Chemical rockets// are the simplest form of space propulsion, and are assumed to be possible from TL 6 onwards. On Earth, they didn't start being used until TL 7, but the technology was there if there had been the necessary will. Technically, the basic physics was understood in TL 3 or 4, but the ability to build a big enough rocket to actually get into space would come along much later.
-The problem with chemical rockets is that they are limited to chemical energy, which greatly limits their //dV//. Even at TL 8 or 9, dV for rocket ships will be limited to a few 10s of km/s.
