This project is composed by two main elements placed in an ideal simmetry on the two walls. The concept is about the relationship between mankind and technology and so then between technology and nature. If in a way tecnology could be intended as detachment of mankind from nature, at the same time (in the recent years and in a future vision) it could be also the way to re-discover it and find a new balance with it. In this vision, electricity become the connection point. As a resource, as a power, as an example to recreate, as a way to create, as a common element, as light and life. In a simple way, our machine recalls the energetic idea from many points of view. In a simpler way, it is an automatic and self-working system composed by separated elements that work together in an unique global movement.
