Thanks to a revolutionary new design from the labs at the University of St Andrews, all that could be well on the way to changin'. Researchers at said institution have teamed up with partners at Strathclyde and Newcastle in order to design an air-fuelled STAIR (St Andrews Air) cell that could theoretically last up to ten times longer than current batteries. Put as simply as possible, this design utilizes oxygen i
