Water Powered Calculator For Green Conscious Consumers
These days, using petrol or diesel would elicit dirty looks and you definitely don’t want that happening. In fact, going green has become such a craze that not only using environmentally friendly vehicles, but also even green gadgets have become the norm. With that in mind, this water-powered calculator must truly catch everyone’s attention. They are even better than solar-powered calculators, which still need battery back up. The water-powered calculator needs no power back-up and can be recharged straight from the tap.
You could fill the calculator with water or any other electrolytic liquid and with the help of a fuel cell inside, the water creates a chemical reaction with the zinc anode and cathode. The resulting electric current can run your calculator efficiently. A cup of water is enough to run the calculator for a month, and nobody can blame you for wasting water either! This green calculator, which costs $19.99, surely takes my breath away!
