Yes, Bite Me!!The Water Powered Calculator makes use of water to generate power.
The calculator is of a standard type, with standard functions.
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.
You may even pour in juice or your favorite beverage into the power cells!!
The water isn't the source of the power. The electricity is being produced by the difference in electrode potentials of the zinc anode and the cathode which are inserted into the water. It's just a battery, it looks a little bit different, but the calculator draws a very small amount of current anyway. So in other words: it is powered by a dissolving hunk of zinc.
The H2O battery has a minimum continuous life of at least 2 years. In addition to this, the H2O battery (unlike all other conventional batteries) can be stored in its dry state indefinitely and can be left to dry out at any time during its life and its life extended indefinitely.
You can have this calculator for 9.95$ (about 400Rs)!!!
The time you feel that this calculator is not working, don't take it to the shopkeeper, look around for a water tap instead......
