I'm no chemist, that that looks HUGE to me!

One of the funny things with true metal air batteries is that they gain weight as they discharge (Zn = ZnO2), and surprisingly (cough) no promoter of the tech quotes Wh/kg for discharged batteries, which is what you'll be carrying around... they partially look so attractive because of that little cheat!
