    ABSTRACT

    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 muscle, but body is also used to do work like warming shelter, food, or otherhumans.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. As the product literature of one

    generator company points out: "Although power output and generation efficiency are

    very low, useful power often may be obtained where a source of heat is available."

    This statement is intriguing because it packs many ideas together and suggests a space

    where electricity is desirable, yet the conventional power grid is insufficient. The first

    half of this paper examines this statement through the history of human electrical

    power develop Men operate the exercise equipment and the energy they spend on gym

    equipment can converted into useable electrical power. With the installation of this

    idea in gyms energy can be added to the local power system via charging of batteries

    (as it is discrete form of energy utilised by humans in gym) or direct usage depending

    on the magnitude of energy. This conversion will assist in meeting the energy needs

    of the gym. These batteries can be re-used again; hence proper utilisation of energy.

    Basic modifications need to be employed to all machines include torque transmission,

    charging of batteries/ direct usage (like heating water or electric stoves), motion of a

    magnet in varying magnetic field resulting in currents in the coils which can thusagain be used directly or charging of batter.
