Toward Zero-Power Computing

Present computers consume too much energy, producing a large amount of heat during computation. This condition is limiting the development of future, more powerful computers and constitutes a bottleneck for the growth of the Internet of Things (IoT) scenario. How can we dramatically lower the energy consumption of computing? What is the minimum energy required by a computing device? Can we build a computer that operates without spending any energy at all? These questions today have new answers and “zero-power computing” has left the pure speculations to enter physics laboratories. In the meantime we discovered that what we though to know about reversible computing is wrong…

Luca Gammaitoni, is Professor of Physics at the University of Perugia, in Italy and the director of the Noise in Physical Systems Laboratory. He is the founder of Wisepower srl a university spin-off company focused on micro-energy generators. He obtained the PhD in Physics from the University of Pisa in 1990. He has developed a wide international experience with collaborations both in Europe, Japan and the USA. His scientific interests span from noise phenomena in physical systems to non-equilibrium thermodynamics and energy transformations at micro and nanoscale. He authored over 200 papers on top-level scientific journals, few books and10 patents.
