Eco Factor: Concept MP3 player generates renewable energy.
The brainchild of industrial designer YuKwang Kang, the Walnut Player is a concept MP3 player that can be “walled rolled” to charge. The device features two spherical objects, which when rolled in your hand, generate renewable electricity to charge onboard battery.
The player has been designed for the visually impaired and anyone else who wants to enjoy sustainable tunes. The device works with Braille writing and features a single button and finger-pressure movement applied along the device generates energy. The movement is also utilized to change tracks and speaker volume.
