We show that a normal (single particle) current density Jx transverse to the ordering wave vector 2kF\stackrel^z of a charge-density wave (CDW) has dramatic effects both above and below the CDW depinning transition. It exponentially (in Jx) enhances CDW correlations and exponentially suppresses the longitudinal depinning field. The intermediate longitudinal I\ensuremath-V relation also changes, acquiring a linear regime. We propose a novel ``current-effect transistor'' whose CDW channel is turned on by a transverse current. Our results also have important implications for the recently proposed ``striped phase'' of the high- Tc superconductors.
