Abstract: Thin magnesium plate 101, which contains metal magnesium, is enclosed by separator 102, which is made of fluid-permeable material and is used as magnesium fuel assembly 100 in magnesium battery 120 in this invention. Magnesium fuel assembly 100 is enclosed from both sides by cathode 103 and provided with electrolyte retention unit 106, which stores electrolyte 107, at its bottom. When magnesium fuel assembly 100 is pushed down from above, separator 102 is impregnated with electrolyte 107, thereby initiating the battery reaction.

Abstract: The present invention is designable on any thickness of magnesium thin plate, providing collectable power supply to the battery part of fuel body. The magnesium air battery 100 provides: the fuel body supply 200 including multiples of magnesium fuel bodies 101 that include magnesium; battery part 300 formed of conductive materials and an electrode that supplies electrons to oxygen; the disposal outlet 400, containing the fuel body integration part 401 that collects the exhausted magnesium fuel body 101; the fuel body holding frame 303, where the magnesium fuel body 101 is in a detachable hold, which moves through the fuel body supply 200, the battery part 300 and the disposal outlet 400.

Abstract: A magnesium battery, which uses oxygen in the air as the cathode active material and magnesium as the anode active material, the invention provides a simple mechanism that enables realization of a magnesium fuel assembly and a magnesium battery capable of uninterrupted fuel supply.

Abstract: The small-sized water treatment equipment providing high water treatment efficiency without using multi-stage structure in the water treatment equipment for obtaining fresh water from raw water, including sea water. The water treatment equipment 10 comprises the evaporation parts 11 and 12, the condenser part 13 and the heat exchanger 24, and the raw water, including sea water, being introduced within the equipment circulates between the evaporation parts 11 and 12 and the heat exchanger 24 via circulating the circulation paths 40a to 40d. Further, circulating water circulates between the condenser part 13 and the heat exchanger 24 via circulating the circulating water circulation paths 41a to 41c, being vaporized at the evaporation parts 11 and 12 and cause vapor-liquid contact in the condenser part 13 with the steam that has circulated the air flow channels 42a to 42c.

Abstract: A magnesium fuel element (100) comprises the magnesium thin plate (101), the front surface separator (102), and the back separator (103), and functions as a fuel for the magnesium air battery. The front surface separator (102) and the back separator (103) are folded, and the plurality of magnesium thin plates (101) are arranged in a stacked manner. The front surface separator (102) and the back separator (103) will be expanded, if the magnesium thin plate (101) moves parallel to the front surface.
