Water Powered Calculator

Water Powered Calculator : Filled water to Run Calculator


Water has many uses in our everyday lives. It is a thirst-quenching drink, it can help clean a wide range of things and is a universal solvent. Recently though, many of you may have heard of water being used as a source of energy. The Water Powered Calculator is a successful attempt to use water as a source of energy.

The calculator has three water batteries which look like the image shown below.

The batteries consist two electrodes made of a special alloy which facilitates a chemical reaction in the presence of water, producing electricity to run the calculator. The battery timing is very impressive considering the fuel is water. The batteries last 2-3 months, during which time the water evaporates and can simply be replaced by simple, everyday tap-water.


The concept of free energy is beautifully exemplified by the Water Powered Calculator. The transparent body allows you to see what goes on inside the device giving you a first-hand glimpse of the process as it is happening. It is a must-have for every mathematician, scientist and engineer.

iPhone 6: iPhone Air, Thinnest Smart Phone ever by Apple

iPhone “Air” concept is thin as two credit cards, light as a feather This  iPhone 6  concept from France is an absolutely beautiful representation of what many are probably hoping the real iPhone 6 from Apple actually looks like. This concept, from Frenchsoft, showcases an extremely thin and realistic “iPhone 6″ that comes with a design that we think is fit for the real iPhone 6 that is rumored for 2014. Like many other iPhone 6 concepts, the designers have been inspired by Apple’s new iPad Air design and have dubbed this device an iPhone 6 “Air.” The device checks in with a 6mm design, thinner than the iPhone 5s, a larger 4.5-inch display that is edge-to-edge with ultra thin bezels, again like the iPad Air, a camera in the upper corner, and their version of iOS 8.
