 Spintronics to replace electronics?

  

According to ScienceDaily, Spintronics could enable a new generation of electronic devices that would work at room temperature, without any loss of energy or dissipation:

Line up all the tiny wires that connect the transistors in a Pentium chip, and the total length would stretch almost a mile. A lot of useful energy is lost as heat as electrons travel that distance.

Theoretical physicists at Stanford and the University of Tokyo think they've found a way to solve the dissipation problem by manipulating a neglected property of the electron - its ''spin,'' or orientation, typically described by its quantum state as ''up'' or ''down.''

No resistance, no heat... Wow! Imagine the frequencies a spintronic processor could reach!
