Propulsor

A propulsor is a mechanical device that gives propulsion. The Dalmer make use of propulsors to power all of their vehicles (Crafts and Ships). 
== Overview ==
Propulsion is the use of force to make movement. The dalmer use power sources to create mechanical force and achieve propulsion. Propulsion is then controlled and directed to allow ships and crafts to move. 
A propulsor converts electrical or mechanical energy into an opposing force that pushes the craft or ship forward. 
== Operation ==
The Dalmer have different propulsion systems depending on the state the vehicle operates in. The three states are solid (ground) liquid (water) and gaseous (air). 
=== Ground Propulsion ===
For ground propulsion the first instrument was the wheel, followed by the now ubiquitous propulsors.
=== Water Propulsion ===
For water propulsion, oars and sail are used. Followed by the common underwater propeller and then the propulsor. Sails are very common in Welt, and among the other races represents the most important form of propulsion for large ships.
=== Air and Low Orbit Propulsion ===
For air propulsion, the most common types are propeller and jet engine, followed by propulsors.
== Other uses ==
Propulsion technology has been extensively studied and has given rise to several derivative technologies, the most important among which is tractor/repulsor technology.
