Another important thing about this new technology is that is "spin-polarized". What this means is that almost all of the electrons are spinning in one direction. This is big news because "spin logic" could work much faster and for much longer than even the best electronics made today.
I think this would be a very important technology for the future of our society if we continue spending energy at the rate we are now. The government is taking steps to make everyday products more energy efficient, and if a technology like this can be perfected and made available for daily use, we would be able to cut down on wasted energy. From the way this article makes this technology sound, we aren't that far away from making this technology ready for mass production.
