Scientist proposes quantum über-battery

Scientist proposes quantum über-battery • Register Hardware: "That battery incorporates a vast number of microscopic capacitors build from electrodes 10nm apart, separated by an insulator. According to Hubler, quantum effects, present because of nanometre scale of the capacitor, prevent the charge on one electrode jumping to the other when the electric field between the electrodes reaches a critical point. The upshot: a capacitor that can hold a monster charge, relatively speaking. Build an array containing billions of these things and you have the makings of an über-battery for laptops, e-cars and the like."
