Re: It's not about batteries
If that is indeed the case, I would suggest that the authors (as usual for academics) have vastly overstated the potential for improving battery life, given that a large chunk of mobile device power consumption tends to be things like displays and wireless data connections. A doubling of battery life might be realistic, but never the 100 times life as claimed.
And as others have noted, "discoveries" like this are ten-a-penny.. always many years away from being scaled up into volume, if at all
I still call Bo-Larks on this, but acknowledge the extreme media garbling of the facts..
