Aussie Researchers Turn Wine Into Green Battery Tech

Leftover wine and overripe citrus fruit could be used to create powerful batteries after Australian chemists uncovered a fresh use for food acids.  Researchers from the University of New South Wales (UNSW) announced they had been granted a patent for the technology that they say could be used to power everything from smartphones and electric vehicles to household solar storage in future.  But the academics will first have to scale up the technology from the size of a coin to a much larger product.  The battery discovery came after a university PhD candidate discovered inconsistencies in the way food acids reacted to metal. ...
