700 Used Coffee Capsules Grow to be Batteries and Keep Clocks Ticking [Batteries]

Coffee makes the realm go ’round for millions everyday, but in Vienna over 700 dirty, used Nespresso capsules were combined with copper and salt water to make battery-powered clocks, that linked together to keep a radio playing away happily.

Supposedly the common coffee-drinker can get through 700 Nespresso capsules a year, that are discarded without thought. On display at Vienna Design Week , the installation highlighted recycling and sustainability, but additionally caught the eye of passers-by as the coffee grounds produced enough energy to keep the radio playing. Certainly something to think of as you brew a higher pot of coffee. [ Mischer'Traxler via Dezeen ]
