Lou, This is very interesting, but being mostly related to electronics, it does not appear to be all that close to what Yildiz is doing … yet spintronics of a different sort could be involved somehow.
Spintronics is a new way of incorporating nano-magnetic effects into electronics, which they have done in the spin-battery - but maybe spintronics has been inadvertently incorporated into magnets, in order to get much higher performance without using circuits, per se. -----Original Message----- From: pagnu...@htdconnect.com Pardon if this is old news, but a 'spin battery' is potentially a very efficient energy source. From the presentation: "The Spin Battery" -- Stewart E. Barnes http://www.physics.miami.edu/~barnes/SpinBattery.pdf (SLIDE 30) Theoretical Maximum If one changes the magnetic state it is possible to recover the Jsd ~ 4eV exchange energy. This gives 4.0 x 10^6 J/kg.
