1) hyperspace tearing
well, any uber geek knows how that works... just watch stargate, or Wing commander
2) Bubble drive
Well, i know what ur thinking, bubble throwing me at the speed of light?
actually, the system works by concentrating a large amount of energy to create a MASSIVE warp in space, effectivley creating a Timespace bubble around the ship.
The jump drive then uses a slightly larger amount of energy to slowly alter the bubble's location in space, and the ship is, thechnically, propelled, FTL.
The ship itself, relative to the bubble is travelling at speed 0, the SPACE, having no mass or limitation on speed, can travel at many times the speed of light.
Upon reaching its destination, the bubble disintegrates, dumping the ship back into realspace.
As for the energy requirements:
Originally, it was powered by Zero-point energy cells, but i have since shifted to the use of UCE, or universal cosmic energy.
UCE is a particle-level design that carries immense energy, but also helps to maintain the stability of the spacetime continuum. With the right equipment, UCE can be turned into energy to power the jump drive
