Watch how 800 potatoes and apples were used to charge a Lumia 930 (video)

Fruits and vegetables are touted as important for our everyday health. But did you know they can also be used to power the latest Windows Phone 8.1 powered Lumia 930?

"In the past, we’ve attempted to charge a Lumia 1020 with the power of lightning as well as sound. Yesterday, multimedia artist Caleb Charland displayed a large art installation that organically charged a Lumia 930 via copper wire, galvanized nail… and 800 potatoes and apples. Yes, you read that right!" Microsoft stated on the official Nokia Conversations blog.

Located at the Westfield shopping center in London’s Shepherd’s Bush, the 8ft-high, 20ft-wide "art project" featured a circuit of metal, apples, and potatoes triggered an electrical current equating to an average of 20mA and 6 volts to power the smartphone.

“By creating this large organic charger to power a Lumia 930 device,” artist Caleb Charland said, “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.”

Phosphoric from the potatoes and ascorbic from the apples, along with the positive and negative electrodes from copper and zinc, created this electrically conductive solution. You can see it in action via the video embedded below.
