Released energy by fusion reaction

In summary, the video explains that the binding energy for deuterium is 2 MeV and for tritium is 8 MeV, resulting in a total of 10 MeV. The binding energy for helium is 28 MeV, which may seem confusing as it is higher than the total energy input. However, this is because binding energy is the energy gained when assembling particles, not the energy needed to separate them. Therefore, 18 MeV is released during the assembly process.

According to the video in the link above the binding energy for deuterium is about 2 MeV and the binding energy for tritium is about 8 MeV so the total for the input items is 10 MeV the binding energy for helium is 28 MeV I am confused by this part if the resulting binding energy is higher that means the extra energy is being taken not generated Can you please explain how come 18 MeV is release , I thought it's needed not released.

Binding energy means the energy you need to add to separate the constituents or, equivalently, the energy you get out by assembling them. Therefore, you gain the binding energy when you assemble something.

1. How is energy released by fusion reaction?

Energy is released by fusion reaction when two or more atomic nuclei combine to form a heavier nucleus. This process releases a large amount of energy, which is the same energy that powers the sun and other stars.

2. What is the source of energy in fusion reactions?

The source of energy in fusion reactions is the conversion of mass into energy, as described by Einstein's famous equation E=mc^2. This means that a small amount of mass is converted into a large amount of energy during fusion reactions.

3. How much energy is released by fusion reactions?

The amount of energy released by fusion reactions depends on the mass of the nuclei involved. Generally, the larger the nuclei, the more energy is released. For example, the fusion of hydrogen nuclei releases more energy than the fusion of helium nuclei.

4. What are the potential applications of energy released by fusion reactions?

The energy released by fusion reactions has the potential to be a clean and virtually limitless source of energy. It could potentially be used to power homes, businesses, and even entire cities without producing harmful emissions or radioactive waste.

5. What are the challenges in harnessing energy from fusion reactions?

One of the main challenges in harnessing energy from fusion reactions is the high temperature and pressure required for the reaction to occur. Another challenge is containing the extremely hot plasma, as it can damage the materials used to contain it. Additionally, the technology for controlling and sustaining fusion reactions is still in the early stages of development.
