One often overlooked interesting property that comes naturally with many mechanical computers (and also applies in this instance) is reversibility [1]. Meaning that not only the input can influence the outputs but also vise versa. Furthermore, this means that no information is erased and it could therefore theoretically perform computation without consuming any energy at all [2].
