      COVER ARTICLE
      Members
      Bob Voss*The hum of the modern building is changing. For more than a century, that hum was the literal 60Hz vibration of AC power pushing through steel conduits filled with copper wire. Now one can walk into a cutting-edge data center, a high-tech hospital, or a "smart" skyscraper today, and they will find a different pulse. It is the silent, efficient, and intelligent flow of DC power delivered through the very same cables that carry our data.*
