An ideal triangulation of a 3-manifold
is {\em efficient} if the only normal
tori and spheres are links of the
boundary of the manifold. We show that
given an efficient triangulation there
is an induced linear functional on the
Kauffman bracket skein module of the
boundary of the three-manifold. The
linear functional is obtained by
renormalization of the TQFT underlying
the Turaev-Viro invariant.
