Battery made entirely from vegetable

If you don´t want to eat your brussels sprouts at least you can use them for something. Thats how the pupils from the City of London Academy together with The Big Bang UK Young Scientists & Engineers Fair thought when they came up with the idea of making a battery out of vegetables.

Copper and Zinc electrodes are placed in each Brussels sprout to create a chemical reaction between the electrodes, generating a current which can be stored and used to power the LEDs on the tree.

Since I´m blogging about graphic design, is this actually design? Well, it certainly is problemsolving and new thinking which is useful for designers.
