-Energy has become one of the biggest problems today's computing system face.<ref>Chris Edwards, '' Go  Backward, Save Energy'', '''CACM 65''' No 11. (2022-11)</ref> There are several ways to address this problem on the pages for [[Quantum Information Theory]] and [[Analog Computer]]s. Other methods include [[Reversible]] computing and methods to avoid the [[Von Neumann Bottleneck]] of putting all data and instructions through a single process stream as he designed in the early days of computing.Rolf Landauer and others at IBM argued that conventual computer were bound by a lower limit based on entropy which is still a very long way away from current computers which are made faster by pushing the limits on what can be processed in the time available.

These digital computers are designed to make no computation errors within the time required to complete their tasks rather than to be efficient.

-The nerve cell consists of a ''body'' from which originate one or more branches. Each branch is a ''axon'' of the cell. The nerve impulse i a change, propagated at a (normally) fixed speed along each axon. This is most often characterized as an electric disturbance, with a potential of about 50 millivolts for about one millisecond. This change in coincident with a chemical change along the axon. At the termination of the axon the chemical character of the change is more obvious and characteristic substances appear as the pulse arrives. Once the pulse is forwarded, all constituents of the nerve cell reverses to there quiescent state. This may not be the same level of reversibility as is evident above, but it is import in minimizing the total energy consumption of the brain.<ref>John von Nuemann, ''The Computer & the Brain'' Yale Univ Press (1958) ISBN 9780300181111</ref>
