(Diet) Day 24 – the nespresso battery, a cool experiment for kids
As part of the VIENNA DESIGN WEEK 2010, Nespresso Austria and the Neigungsgruppe Design invited five studios to a competition with a focus on the valuable material aluminium.
The installation ‘Nespresso-Battery’ demonstrates that there is a lot of energy in Nespresso Capsules. Invisible Energy becomes visual via ticking sweep hands and thus wants to focus on the importance of collecting and recycling the valuable material aluminium. The installation wants to encourage customers to bring their used Nespresso Capsules back to the Boutiques and other collection facilities, in order to be recycled.
The energy for the movement of the sweep hands is powered by 17 simple, self made batteries. Each battery-block consists of used old aluminium capsules, coffee grounds, strips of copper and salt water. In this mixture between a soil battery and a salt water battery the aluminium functions as the anode, the copper as cathode and the salt water as electrolyte. Due to a chemical reactions a small, but usable, amount of energy is created. Each battery produces about 1,5 – 1,7 Volts of potential and enough power to run a electro – mechanical Quartz clockwork.
The content of all batteries (old capsules and coffee grounds) is about ~ 680 -700 Nespresso Capsules – an average year consumption of one person. All 17 batteries interconnected and well moistened would be able to power a small radio.
In the end ‘Nespresso-Battery’ won the contest and was shown in the display window of the Nespresso Boutique Mahlerstrasse from 1st – 10th of october 2010.
