DESCRIPTION:	In contemplating the headlong rush toward miniaturization rep
 resented by Moore's Law\, it is tempting to think only of the progression 
 toward molecular sized components. There is a second aspect of Moore's Law
  that is sometimes overlooked. Because of miniaturization\, the energy eff
 iciency of information processing steadily improves.  \n	But there is an i
 nefficiency for communications.  It is caused by the difference in voltage
  scale between the wires and the transistor switches.  Transistors are the
 rmally activated\, leading to a required voltage >>kT/q.  Wires are long\,
  and they have a low impedance\, allowing them to operate efficiently even
  at ~1 millivolt.\n	The challenge then is to replace transistors with a ne
 w low-voltage switch that is better matched to the wires.  I will present 
 some of the technical options for such a new switch\, which are being expl
 ored by the new NSF Science & Technology Center for Energy Efficient Elect
 ronics Science.\nhttp://www.e3s-center.org/
