We can expect about 300 watts of power output should result in an average speed of about 18 mph. Let's assume a 9 mile one way distance. That will take 0.5 hours to get to work, and 0.5 hours to get back. Total energy 300 watts X 1 hour = 0.3 kilowatt hours.

The average athlete will have approximately 285 grams of stored ATP in his or her entire body. That amount of ATP will be consumed in a just few seconds of work. At any time, athletes have only about 10 seconds worth of ATP-PC.

A healthy human can produce about 1.2 hp briefly and sustain about 0.1 hp indefinitely; trained athletes can manage up to about 2.5 hp briefly and 0.3 hp for a period of several hours. ***********************. for the second question, let's propose a task to be done two different ways... A Moderate commute.

Over 60 million produced. Power is 2.9 kilowatts or 3.9 horsepower. At a steady 30 km/hour which is about 18 mph, they will get over 300 miles per gallon of gasoline. Except in quiet rural areas, almost nobody rides that way, they stand on the throttle - so we can expect about 120 miles per gallon.

If you extracted it at 40 watts, then yes.(or at least fed the enery through at 40 watts). how long depends on the size of the person. i have no idea how much energy(assuming chemical energy) is in the human body. i'd say the 40 watt bulb would stay lit for a long time since the body idles at around 100 watts.

The Immediate Energy system, or ATP-PC, is the system the body uses to generate immediate energy. The energy source, phosphocreatine (PC), is stored within the tissues of the body. When exercise is done and energy is expended, PC is used to replenish ATP.

Like an automobile only runs on gasoline, the human body runs on only one kind of energy: chemical energy. More specifically, the body can use only one specific form of chemical energy, or fuel, to do biological work – adenosine triphosphate (ATP).

Energy in a human body. #1. Researcher X. I only have a basic knowledge biology, but I've wondered about this before. From a fully charged adult male human to dying of lack of nourishment; in case of chemical energy from food, this is often said to be three weeks.

Answers.com® is making the world better one answer at a time. According to the Center for Space Power and Advanced Electronics, a NASA commercial center in Alabama, the human body is on average 15% fat, capable of producing 11,000 watt hours. When the average Joe eats his daily bread, he takes in 3,300 watt hours.
