Our beloved beer can battery

This is a simple way of showing all the parts of an Aluminium-Air cell in action. We're using an empty aluminium beer can which contains our electrolyte plus a red plastic cathode assembly, fitted with a fan. Oxygen, from the air, enters the electrolyte through the membrane on the red cathode assembly. The membrane splits the oxygen which dissolves in the electrolyte, making the reaction work. As you CAN see, the power is instant and steady.

FACTOID: One empty can CAN recharge an iphone battery 35 times!

Many thanks to the Captain at BREWDOG for keeping us hydrated and also thanks to Ghost_K for the really cool track, named STOP (Blue Mix).
