How To Charge Your Phone Organically With Apples And Potatoes
What uses 800 apples and potatoes, about 1600 nails and a lot of electrical wiring? An organic phone charger. If you are now saying that all this sounds too fantastical to be true… Well reserve your judgement just yet!
This has actually been done and we’ll be going into the dynamics of it just now. A strange and wonderful thing happened in London the other day. As people looked on in amazement, an array of 800 apples and potatoes was used to charge a Nokia Lumia 930 smartphone, on the 24th of July, in front of the Westfield Shopping Centre, Shepherd’s Bush. These apples and potatoes were sort of connected together with galvanized nails and a lot of electrical wiring. Impossible, you say? Not so. And the pictures prove it.
How did it all happen? Well, this is just an enlargement of a fairly common classroom experiment where a single appleis used to run a digital clock, but more on that later.
This dynamic artwork was funded by Microsoft Corporation, who had, some time ago, taken over Nokia, the cellphone company. They thought to use the same principle that was formerly used in the classroom, but just on a larger scale and for a more widely needed purpose. To that effect, they commissioned artist Caleb Charland to scale up that experiment. He calls it the organic charger.
He did it by stringing up 800 apples and oranges with galvanized nails and wiring to build a circuit which can output 20 mA of current on the average at roughly 6 volts. During the fascinating demo, he used the output to charge a Nokia Lumia 930 using a wireless mat. Now that is INNOVATION!
How does it work?
The principle is pretty simple. Galvanized nails are iron nails coated with zinc. Once the nails are pushed into the apple or potato, it forms a very weak galvanic cell. In simple terms, a weak battery. What happens when you connect the two nails using a bit of wire, is that the nails form two electrodes, and the juice in the fruit or vegetable acts as an electrolyte. The zinc on the nail gradually dissolves, and a positively charged ion (an atom which has more protons than electrons) is formed. This leaves behind two electrons, or negatively charged particles. These electrons pass through the connecting wire to the other electrode where they combine with positively charged ions to form hydrogen gas. This flow of electrons is an electric current. Actually if both electrodes have zinc, this process ought not to work well, so presumably one nail of each pair was not galvanized. Be that as it may, as more apples or potatoes are strung together, the voltage goes up.
Now that may seem like a whole lot of science to you – but in basic laymen terms its pretty simple. The fruit or vegetable, with the pair of nails embedded in it,functions as a weak battery when you need it to. As a result they need to link up a series of this and voila! You have a phone charger!
Caleb, who, apart from being an artist, is also a part-time scientist, says that this simple phenomenon has always fascinated him. The simple classroom experiment using an apple has never ceased to inspire the imagination of countless young students. Caleb also says that this project was a challenge as he has never worked on something of this scale before, and this addresses the common curiosity we all have about how this world works. It also hints at the need for generation of electricity on a large scale, organically. Watch the video to hear Caleb talk about his organic charger.
Now is that amazing or what?
