A watt is the SI unit for power. A watt is equal to 1 Joule per second , or (energy in an amount of time).[1] A watt of power is about equivalent to a person holding out their arm and moving their fist up and down each second.
Deep knee bends output about 100 W of power. This is about the average total power input (primary energy consumed as food) of a person over a normal day, which is why R. Buckminster Fuller came up with the idea of this calling this an energy servant. Since it's actually a unit of power, this site discusses them as power servant.[2]
The average power use (end use rather than primary), for a typical person in Canada or the USA, taken over the course of a day, is about 10,000 W.
