Nokia Successfully Charged Cellphone Using Potatoes And Apples

By -

Chemistry is a dull subject but then there are ways to learn it in more productive and interesting way. Such as food batteries! One of many science projects designed for children of ages 7 and above is making a battery using a potato.

It is possible because of the chemical reaction between two dissimilar metals; such as nails inserted separately in two halves of the potato and the juices in the potato. These reactions create a small voltage to power a very small electrical devices.

This simple science project was actually used to wirelessly charge a Nokia Lumia 930 smart phone which comes off as a surprise but not an impossibility.

Microsoft and Carphone Warehouse teamed up with an artist (and part time scientist) Caleb Charland to create an “organic charging” art piece in order to wirelessly charge the smartphone. This art piece entitled “Back to light” was inspired from school science project – food battery but on a much larger scale.

The “organic charging” project comprised of an enormous 20-ft wide and 8-ft high wall packed with 800 apples and potatoes. The large setup was connected with a wireless charger to top-up the battery of a brand new Windows 8.1 smartphone. An average of 20 mA current and 6 volts flow through the set-up to charge the smartphone.

Caleb says, “By creating this large organic charger to power a Lumia 930 device, this work speaks to a common curiosity we all have for how the world works, as well as a global concern for the future of Earth’s energy sources.”

Nokia Lumia 930 was released this month and the project is a fun way to advertise its power and versatility. It is indeed a powerful smartphone; running on Windows 8.1 with Gorilla Glass 5-inch OLED display, powered by a 2.4 GHz processor and features a 20 MP rear camera.

This project was unveiled at Westfield Shopping Center, Shepherd’s Bush, London.
