Query: Superpotential of Three Dimensional ${\cal N}=1$ Heterotic Supergravity   We dimensionally reduce the ten dimensional heterotic action on spacetimes of
the form ${\cal M}_{(2,1)}\times Y$, where ${\cal M}_{(2,1)}$ is three
dimensional maximally symmetric Anti de Sitter or Minkowski space, and $Y$ is a
compact seven dimensional manifold with $G_2$ structure. In doing so, we derive
the real superpotential functional of the corresponding three dimensional
${\cal N}=1$ theory. We confirm that extrema of this functional precisely
correspond to supersymmetric heterotic compactifications on manifolds of $G_2$
structure. We make some comments on the role of the superpotential functional
with respect to the coupled moduli problem of instanton bundles over $G_2$
manifolds.
