Charge your phone with Apples and Potatoes. SEE How It Works!

Fruits and vegetables are universally promoted as healthy. Certain fruits and vegetables are rich sources of vitamin C, but these rich sources (citrus fruits, strawberries, green peppers, white potatoes) are spread over many fruit and vegetable categories. Other fruits and vegetables, including avocado, corn, potatoes, and dried beans, are rich in starch, whereas sweet potatoes are mostly sucrose, not starch.
Meanwhile, A strange art installation in the Westfield shopping centre in west London, England by artist Caleb Charland was essentially a large-scale reproduction of an old classroom science experiment where a potato is used to charge a small digital clock.  It is amazing that you can now  charge your phone with apples and potatoes.
By stringing 800 pieces of fruit and vegetables together with galvanized nails and wire, artist Caleb Charland was able to scale-up the power output so much that it could charge a mobile phone – in this case a Nokia Lumia 930, charged via a wireless mat.
The hand-built circuit created an electrical current of an average 20mA and around six volts.

The utter simplicity of this electrical phenomenon has endlessly fascinated me. Many people have had the experience of drawing power from fruit in the classroom, and it never ceases to inspire the imagination of all aged, said Charland
2014 has been a great year when it come to charging of cell phone without electricity , honestly speaking this is th most amazing off it all.
“I have never worked with anything on this scale before, and it was a challenge. 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.”

The project was a publicity stunt paid for by Microsoft, which has recently bought handset maker Nokia, and the Carphone Warehouse.

How does it work?

According to  Matthew Sparkes, the head of dept of tech for telegraph, The energy actually originates from the metal connecting the apples and potatoes, rather than the fruits and vegetables themselves. The zinc from the galvanized nails and copper act as electrodes, and the apple or potato acts as an electrolyte.

Atoms from the zinc electrode dissolve into the apple or potato as a positively-charged ion (an atom where the number of electrons is not equal to the number of protons), leaving two negatively-charge electrons stranded behind.

These electrons pass via the wire connecting the two electrodes in order to join with hydrogen ions from the apple or potato to form hydrogen gas. This flow of electrons is electrical current.
