Power generation by the human body

• If power is like the strength of a weightlifter, energy is like his endurance. Energy is a measure of how long we can sustain the output of power, or how much work we can do. Power is the rate at which we do the work
• One common unit of energy is the kilowatt-hour (kWh). If we are using one kW of power, a kWh of energy will last one hour. If we use 10 kW of power, we will use up the kWh in just six minutes.

    BTU is the amount of energy needed to raise the temperature of 1 pound of water 1 degree F
    1 horsepower is equivalent to 746 watts
    One BTU is equal to 1,055 joules, or 252 gram-calories or 0.252 food Calories.
    Btu x 0.293 = W  ( kW x 3414 = Btu )
    One watt is equal to 1 Newton-meter per second (Nm/s).

• Measure your power output by running up a flight of stairs. Power (W) = (height of stairs (m) / Time to climb (s) ) * weight (N)
