-Contained here are some notes on the sort of technology available in a **Yags SciFi** setting.+Contained here are some notes on the sort of technology available in a **YAGS SciFi** setting. Advancements are broken down by technology level for each type of technology.
  
-===== Space Drives =====+In reality, the advancement from one stage to the next is quite fluid - hard definitions are only used here to simplify the game mechanics. In general, all else being equal, a culture that is one TL ahead of another can clearly defeat the latter in direct combat. Obviously, if you're technology isn't as good as the other guy's, then your aim is to avoid direct combat. Two technology levels of difference is a massive advantage - compare early 21st century to early 20th century for example.
  
-Most of the following discussions are about //reaction drives// - those that work by throwing something out the back to push a space craft forwardsAll 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. +{{indexmenu>.}}

-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.  +
