The product used in everyday life offers the user an environmental design solution. It is a groundbreaking development that portable power technology operated by an inexhaustible resource - "water". The technology utilizes two electrodes consisting of specially formulated alloys, positive and negative. When they are immersed in water an electrochemical reaction takes place resulting in the production of electrical energy. To maintain a constant supply of energy simply refill as the water evaporates every 2 to 3 months. The water battery
