I came across this article about warp drives:

I thought this bit was interesting:
I wonder if negative energy is related to negative temperature, discussed here: Negative temperature. (http://cassiopaea.org/forum/index.php/topic,30089.msg389499.html#msg389499) If so, then all they have to do is create a largish "quantum energy mountain" in a magnetic field, flip the magnetic field, and fly off into space.
I also remember reading in a 2003 Scientific American magazine physics special that moving a mirror with a laser bouncing off it can create pockets of negative energy, although I can't recall the specifics.

What would it be like to travel at warp speed?
You would have an initial velocity as you set off, and then when you turn on the ring of negative vacuum energy it augments your velocity. Space would contract in front of the spacecraft and expand behind it, sending you sliding through warped space-time and covering the distance at a much quicker rate. It would be like watching a film in fast forward.
Even if travelling at warp speed is theoretically possible, don't the huge energy requirements make it unlikely?
When the idea was first proposed mathematically in 1994 it required a vast amount of negative vacuum energy which made the idea seem impossible. I did some work in 2011 and 2012 as part of the 100 Year Starship symposium and discovered ways to reduce the energy requirements by many orders of magnitude, so for a 10-metre diameter spacecraft with a velocity of 10 times light speed, I can reduce the negative energy needed.

So they can fly around the would in a few minutes using less fuel.
