It +mirrors the permacomputing idea of using surplus energy for slow, +computing-intensive tasks. + +The concept emphasizes the storage of information on a rather short-term +basis. An example of a more long-term use of surplus energy would be the +gradual optimization of software: when initially compiling a program, the +compiler would only do rather lightweight optimizations, and the heavier and +more computing-intensive ones would be postponed to times of abundance. + +See also: + + * [Original 2021 paper by Switzer and Raghavan](https://arxiv.org/abs/2108.01035)
