First, there was the battery cell operated calculator, followed by the solar-powered calculator, now here is the water-powered calculator. Yes, no batteries required, you can recharge it straight from the tap. It functions just like any pocket calculator, but can be filled with water or any other type of electrolytic liquid. Equipped with a fuel cell, the water inside the calculator creates a chemical reaction with the zinc anode and cathode. This chemical reaction causes an electrical current, and presto, you can solve all those mathematical equations! The water-powered calculator can calculate for up to a month on less than a cup of water.
