One of the greatest limitations in processor design today is energy efficiency or rather, the lack thereof; we simply cannot provide enough power to our increasing number of transistors.

However, it need not be that way. Reversible computing to the rescue! With a little help from thermodynamics, this model of computation can – in theory – provide fully optimal energy usage. There is just one tiny problem: nobody has actually been able to implement it practically.

In this talk, I will explain the idea behind reversible computing, dive into some of the challenges in implementing it, and discuss why I am not writing this from my sweet new reversible computer.
