<p>A portable, direct current electric generator (10 or 70) uses a salt water solution as an electrolyte. An outer housing (11) in the form of an open-topped, rectangular box is provided, and an inner housing (40) having a compartment for receiving the salt water electrolyte is placed within the outer housing. A space is provided between at least one of the walls of the inner housing and a wall of the outer housing, and provision is made to supply air to this space (via 29). The inner housing member (40) has an aperture (47) in the side facing the air space, and an air cathode member (50) is secured in this aperture. The air cathode member (50) is air-permeable, but is impervious to water on the side facing the air space. A metal anode (34 or 75), preferably made of magnesium, aluminum, or a magnesium-aluminum alloy, is removably secured to a removable cover (14 or 74) placed over the open top of the inner and outer housing members to extend into the salt water solution within the inner housing member. Electrical connections (25, 26 or 80) are provided for connecting a load between the cathode and the anode. When the anode is consumed, it is removed from the cover and replaced with a new anode.</p> |
