A 'warp drive' with reasonable total energy requirements

Authors: *Chris Van Den Broeck

Comments: 9 pages, 1 figure; minor modifications; typos corrected

Report-no: KUL-TF-99/18

I show how a minor modification of the Alcubierre geometry can
dramatically improve the total energy requirements for a `warp
bubble' that can be used to transport macroscopic objects. A
spacetime is presented for which the total negative mass needed
is only in the order of grams, accompanied by a negligible
amount of positive energy. This constitutes a reduction of the
absolute value of the energy by 65 orders of magnitude. The new
geometry satisfies the quantum inequality concerning WEC
violations and exhibits the same advantages as the original
Alcubierre spacetime.
