A lantern and power source includes a hollow housing with a hollow tubular power cell formed within the housing. The tubular power cell includes an ano de rod formed of a magnesium alloy and extending along the longitudinal axis of the hollow tube. An opening formed in the side wall of the hollow tube is covered by a metal cathode plate, and the tube is filled with salt water. An electrical lamp is mounted on the housing and has one terminal connected to the anode and one terminal connected to the cathode such that a how of electrons caused by the caustic reaction o f salt water with the magnesium alloy anode will light the lamp. |
