MK-3 Terran Alliance Light Pulse Cannon v MK-8 Ascendance Plasma Cannon.
Energite is a very powerful fuel source which doubles certain energies if they are sent into it. Method of extraction is to wait for near-supernova stage then use Anti Gravity lasers to remove surrounding layers to prevent a black hole from forming. By that time, a somewhat small quantity (normally 0.001% of the star's mass if over 50 Solar Masses) of energite is produced.
