Wondering what this amorphous contraption is? Well, what if I tell you that it’s actually a fully functional shower! The self-heating Piezo Shower is no pipe (pun intended) dream as its been designed to generate electricity through movement and friction which in turn heats the water. As the name suggests, Piezo fibers have been inserted to the pipes to generate piezoelectricity. This energy efficient shower is the brainchild of designers Sebastian Jansson,Fernanda PizÃ , Victor Stelmasuk and Natalie Weinmann.
