Copper market’s biggest whale fuels speculation of a major shift
The world’s single biggest buyer of copper, State Grid Corp. of China, has slowed its purchases of copper wire this year.
Londoners were amazed to see Friday how a Nokia Lumia cell phone was being charged by a strange gadget made of 800 apples and potatoes connected with nails and copper wire.
The functional art installation, by Caleb Charland, was created outside the Westfield shopping centre in Shepherd’s Bush, essentially just a large-scale version of the classroom science experiment where a single potato is used to power a digital clock.
The Nokia Lumia 930 is the brand new flagship smartphone running Windows Phone 8.1 — the most advanced Lumia yet.
See how this “organic charger” came to life:

Then we end up raising the cost of potatoes like we did with corn with the advent of ethanol. Lol!

It’s only “organic” in as much as the battery acid is being provided by an organic material. The energy to charge the phone is being provided by the zinc that is galvanizing the nails. Hence, this is still a charging technology that relies on the mining of natural resources…. not magic.
