We all know that batteries are generally eco-friendly in nature. However, the Nespresso Battery is by far the most eco-friendly of them all. This one of a kind battery is made from 700 used coffee capsules and has the ability to power wall clocks. Presented during the Vienna Design Week, the Nespresso Battery uses aluminum along with strips of copper in the capsules, coffee grounds and salt water to make the probably most eco-friendly battery on earth. With this product, carbon emission in manufacturing batteries will definitely be reduced. In addition, the moment you hung your wall clock along with the Nespresso Battery, it instantly create an eye-catching decorative item.
