  When Morris and Thorne first proposed that wormholes might be actual physical
structures suitable for interstellar travel, they needed to pay close attention
to certain traversability conditions such as low tidal forces, which placed
severe constraints on the wormhole geometry. Even more problematical was the
need for "exotic matter" resulting from the unavoidable violation of the null
energy condition required to hold a wormhole open. The purpose of this paper is
to overcome these problems by starting with the charged wormhole model of Kim
and Lee and assuming a noncommutative-geometry background: the violation of the
null energy condition can be attributed to the latter, while the electric
charge allows the reduction of the tidal forces to acceptable levels without
invoking the trivial zero-tidal-force assumption.
