The human heart beats about 40 million times a year, which adds up to more than 2.5 billion times in a 70-year lifetime. This results in approximately 2 to 3 billion joules of work in a lifetime, which is a huge amount.
Given this and the calorific value (45.4 MJ/kg) aswell as the density (0.82 kg/l) of Diesel, the energy created by our hearts over our lifes is about equivalent to 81 l of Diesel.Aug 13, 2019

Does the heart produce energy?

How does the heart create electricity?
An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). This is a small mass of specialized tissue located in the right upper chamber (atria) of the heart. The sinus node generates an electrical stimulus regularly, 60 to 100 times per minute under normal conditions.
How much energy does the body produce?
The human body produces more energy than you might think Assuming an average calorie intake of 2000 per person and 7 billion inhabitants on planet earth, we process a staggering 58.58 petajoules (59x1015 J) of energy each day and 21.38 exajoules (21x1018J) per year.Apr 17, 2019
What keeps the heart beating?
Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart: SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node.Jan 5, 2019
How much electricity does the body produce?
Theory. The average human, at rest, produces around 100 watts of power. [2] Over periods of a few minutes, humans can comfortably sustain 300-400 watts; and in the case of very short bursts of energy, such as sprinting, some humans can output over 2,000 watts.Dec 6, 2014
How many volts does the heart produce?
It is a self powered pump, as it produces certain action potentials of up to about -50 millivolts, with some 5 nanoAmperes in amplitudes of pacemaking current, that travels thru the heart muscles triggering its two chamber series of pumping actions. As measured thru the skin as an EKG signal of about 1 millivolt.
How many volts does the heart make?
Voltage Used to Resuscitate a Human HeartBibliographic EntryResult (w/surrounding text)Standardized ResultGlencoe Health. 2nd ed. Glencoe-Mcgraw Hill. California, 1989: 555."As it senses an abnormal pattern, it sends out a 700- volt shock that can be repeated three times."700 V2 more rows
What happens when you get shocked by 120v?
High voltage currents of 500 V and more can cause deep burns, while low voltage currents consisting of 110–120 V can result in muscle spasms. A person can get an electric shock through contact with an electric current from a small household appliance, wall outlet, or extension cord.
What is the pursuit of wealth?
The pursuit of wealth is now largely the pursuit of information and its application to the means of production ... One can postulate that in the next few decades the attraction and management of intellectual capital will determine which institutions and nations survive and prosper, and which will not.
How much gas does a van use?
I drive a van (similar in mileage to a small truck) that uses roughly a gallon of gasoline for every 20 miles driven – on a very good day. Now a gallon of gasoline is roughly 4 kilograms of a highly energetic substance. A human living for a day will use roughly 2000 kilocalories (kcal – food calories are measured in kilocalories) a day.
Question
a) The average power output of the human heart is 1.33 watts. How much energy does the heart produce in a day?
Gravitational Potential Energy
When an object is lifted from the surface of the Earth, an upward force acts on it which the greater than the weight of the object. This upward force while lifting the object, performs work on the object.
What is the power of the heart?
Power of the Heart’s Electromagnetic Field. The heart, like the brain, generates a powerful electromagnetic field, McCraty explains in The Energetic Heart. “The heart generates the largest electromagnetic field in the body. The electrical field as measured in an electrocardiogram (ECG) is about 60 times greater in amplitude than ...
What is the heart like?
The heart is like the greatest receptor of the body, gathering all of the external data as consciousness does, and then it is relayed to the brain where it is made logical sense of and stored for later retrieval. The brain acts like a storage device for the incoming data or consciousness of the heart.
What is the heart's electromagnetic field?
The heart’s electromagnetic field contains certain information or coding, which researchers are trying to understand, that is transmitted throughout and outside of the body. One of the most significant findings of HMI’s research related to this field is that intentionally generated positive emotions can change this information/coding.
Is the heart the brain or the brain?
My theory is that the heart is consciousness, not the brain. The brain just interprets what the heart is saying, like an information centre that is able to process the incoming data or consciousness of the heart. It is the heart that is the true being, the true self.
Introduction
- During my web browsing, I sometimes encounter a statement that just seems too incredible to believe. Figure 1contains such a statement. It states that the human heart “creates” daily an energy equivalent to driving a truck for 20 miles. I thought about this statement for a minute and it makes no sense. I drive a van (similar in mileage to a small truck) that uses roughly a gallon of g…
Background
- First, we need to gather a few facts. 1. The heart has an average mechanical power output of 1.3 W.We can roughly estimate the hearts mechanical power and daily work output as shown in Figure 3.Figure 3: Heart Mechanical Power and Work Computations. 2. The heart uses an average of ~6 W of chemical power input to generate 1.3 W of mechanical power output.I have seen quo…
Analysis
- Figure 5 shows my calculation of the chemical energy used by the heart in a day compared with the chemical energy used to move a truck 20 mile. The heart uses far less energy per day (~1%) than is contained in one gallon of gasoline.
Conclusion
- I had to take a closer look at the statement that a heart beating for a day consumes as much energy as a truck moving 20 miles. I have shown that the magnitudes of these values are far different.
Appendix A: References on Cardiac Efficiencies
- Figure 6 contains a reference tableof reported cardiac chemical-to-mechanical work efficiencies. I decided to use 20% as a rough value that is close enough for my purposes. Save Save
