Contra-Terrene Engine: weird word for an antimatter engine. Make a explosion, push hot gases and energy out the rear of the ship. Like a rocket, but with a much bigger boom.
Jacketed-Photon: "harnessed light drive". Hmm. I read this as using photons like the ions in the Ion Engine
Quantum Engine: dunno
Wave-Motion Gun, Incinerator Beam, Ripper Beam: focuses fusion heat at the target. Think heat-ray, only the heat is SUN hot.
Phoenix-D
