A little perspective
Human mechanical output is about 2 times larger on this measurement.
Human mechanical output: The sustained rate at which a person can perform mechanical work, such as cycling or lifting.
Measurements, assumptions & sources +
Laptop in use
A chosen 50 W electrical draw. Workload affects actual consumption.
Defined examples — our methodology
The marked power is calibrated. Unmeasured illustration details are representative.
Human mechanical output
A chosen 100 W sustained mechanical output, not total metabolic power.
Defined examples — our methodology
The marked power is calibrated. Unmeasured illustration details are representative.
