A simple classroom (no soldering) project to show aluminum air batteries in use. In this instructable I will show you how to create a simple 3 cell aluminum air fuel cell using household aluminum foil and saltwater. You can use this to drive a small light or possibly a motor. This device will function for extended periods as long as the fuell cell is periodically recharged with electrolyte and the aluminum foil is replaced when power output drops below acceptable levels.
