Thereby reducing the negative energy requirements of the warp drive spacetime arbitrarily as a function of A(ct,r_s). With this function new quantum inequality restrictions are investigated in a general form. Finally a pseudo method for controlling a warp bubble at a velocity greater than that of light is presented.14 pages, LaTeX2e, 1 eps figureGeneral Relativity and Quantum Cosmologytext
