Harmonic dampening technology is used frequently in other industries, too. In the picture below, you can see high voltage transmission lines using harmonic dampeners to cancel out wave motion induced by wind or earth quakes.

The dampers on high voltage lines take many forms, but the most basic is that of two heavy lead weights attached near the end of each line segment near the transmission line support tower or pole.

Not pretty and very low tech. I think I like my Camaro's early stick-on lead weights better than the latest incarnation of the damper.
