Meet Ampere’s Shower Power: a Bluetooth shower speaker that generates 100% of its power from water as it plays your music and podcasts. It is made of 100% recycled ocean plastic too. As the developers explain, these speakers have a hydropower system that works like a water wheel.
Shower Power turns on automatically when the water flow starts. It has a “sound wave” diffuser to send audio in all directions for 360-degree sound. A waterproof remote is also available for it. Like what you see? You can find this project on Indiegogo.
