Water Powered Calculator

We have all heard about battery powered calculators and solar powered calculators, but water powered calculators… this is the first. Well, water powered calculators make use of water to power the calculator.

How does this happen? Well, water creates a sort of chemical reaction in the fuel cell that has zinc anode and cathode, and this reaction creates an electrical current. This current powers the calculator. The calculator is of a standard type, with standard functions. However, when you find it not working for want of power, just take it to the nearest fountain for a re-charge.

This device is useful for people who need calculators as part of their work. It saves the hassle of constantly trying to power up calculator by buying batteries. If the idea of using water for power comes a long way, it can be used to power up larger devices.
