Human power is work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans.
World records of power performance by humans are of interest to work planners and work-process engineers. The average level of human power that can be maintained over a certain duration of time, say over the extent of one minute or one hour is interesting to engineers designing work operations in industry. Human power is sometimes used to generate electricity that is stored.

Famous quotes containing the words human and/or power:
“Catholics think of grace as a supernatural power which God dispenses, primarily through the Church and its sacraments, to purify the souls of naturally sinful human beings, and render them capable of holiness.... Protestants think of grace as an attribute of God rather than a gift from God. It is a shorthand term signifying God’s determination to love, forgive, and save His human children, however little they deserve it.”
—Louis Cassels, U.S. religious columnist. “The Catholic-Protestant Differences,” What’s the Difference?, Doubleday (1965)
“A new degree of intellectual power seems cheap at any price.”
—Ralph Waldo Emerson (1803–1882)
