Water Calculator

When people all over the world are talking about sustainable development and eco friendly products, I felt like reviewing a product that uses a renewable source of energy as a power source…WATER. You may think this is nuts. What portable device would operate on water? Here you have it, a water powered calculator that saves you from the vicious circle of purchasing batteries. Considering water is a readily available resource, filling the calculator is not a big problem. It doesn’t only work on water, but any electrolytic liquid too! Fill it’s fuel cell to start a chemical reaction that will start up between its zinc anode and cathode to generate electrical current, powering the calculator. This calculator is priced at just $19.99. If you feel like getting one, follow this link..
