The Worsley-Twist warp drive does not depend upon traditional emissions of matter to create thrust. Rather, the drive creates a change in the curvature of the space-time continuum — thus allowing travel by warping space-time. Worsley & Twist patent application recently suffered another setback. The Examiner has now requested a working model:

Applicant is required to furnish a model of the instant invention. 35 U.S.C. 114. See Also 37 C.F.R. 1.91.

Among other rejections, the Examiner has asserted a rejection under 35 U.S.C. 101 for lack of utility — finding that the invention is inoperable.
