A mechanical computer component uses membranes thinner than a human hair
Dr. Erick Romero
A computer component that uses vibrations rather than electrons could approach the physical lower limit for energy use when processing and sending information.
The minimum amount of energy needed for a computer to perform a computational step is called the “Landauer limit”, named after the 1960s physicists Rolf Landauer. In his calculations, Landauer did not consider any specific computer design, but rather the basic energy cost required to manipulate information, like erasing or re-writing a bit.
Conventional computers, which are …
