Homemade Metal Air Battery - Part 2

In Homemade Metal Air Battery - Part 2 video are shown three easy made metal air batteries,... Silicon Air Battery, Tin Air Battery and Zinc Air Battery. In construction I use simple materials and I make cells in same way for observing the voltage of each cell. I show the voltage of all three metal air batteries with alkaline electrolyte KOH and neutral electrolyte NaCl. The materials are easy to find in the store or on internet.
