The proposal describes a warp bubble, traveling faster than light, involving immense amounts of energy. But creating the warp bubble in the first place, and getting out of it without forming a black hole and getting gobbled up by the black hole, would appear to involve a surface of infinite blue shift, which requires shock wave in space time of infinite energy density.
