This is amazing. I remember growing up with the idea of everything being run with super conductors. They were going to revolutionize the electrical industry. Components using so little power that there would no longer be a need for thick heavy and bulky wires to power homes. To my knowledge that has never come to fruition. I have not heard much about this idea in recent years, but this looks like one step closer. One question however; if our electronics are using so much less power for more technology, why do our phones use so much battery power and go dead within a day, as opposed to the "dumb" phone that would stay charged for a week or more? I'm a simple kind of guy, and this kind of baffles me.

The smartphones simply use more power because of a multitude of power hungry features that we continuously use on them. The lithium ion battery simply can't hold enough juice for all that functionality.
This just reaffirms my contention that technology is not always a good thing.
Two primary differences and some less primary ones: Screens nowadays are much larger and use far more power. The SoC (system on a chip (CPU, radio, etc)) is far more powerful nowadays. Battery tech is having a hard time keeping up with power consumption. So yeah, yay for graphene!
