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…
