By effectively expanding space behind you and compressing it in front of you, you never actually travel faster than light. But as has been stated the amount of energy to do this is immense.

A good book on this type of stuff is Physics of the Impossible. It talks about warp drives, force fields, phasers, transporters, all the sci-fi stuff, and the science that could some day make it happen (or not).
