Question

What is drawback of energy obtained from fusion?​

Answer 1

Disadvantages of Nuclear Fusion

1. Energy Input VS Energy Output

Extremely high levels of heat are necessary in order to fuse the two nuclei of the atoms together. This requires a large amount of energy, nearly as much energy as will be produced. For this reason, nuclear fusion energy is truly not plausible.

2. Expensive Construction Costs

The facilities, experts, and scientists that are needed to successfully run a nuclear fusion plant are immensely expensive. Along with these high costs, it also costs quite a pretty penny to harness the energy that is created.

3. Little Understood

Nuclear fusion is a very new form of energy, and the only way it would be truly usable on a large scale production is if cold fusion was perfected, which is a long ways off. The full scope of dangers and effects of nuclear fusion energy isn’t understood yet, because it simply has not been around long enough.

4. No Materials For The Job

One of the other big problems with nuclear fusion is the fact that there is no known material that can handle the extremely high heat that is necessary for nuclear fusion. Until there is something that can sustain the high temperatures, no future for the energy source is for seeable.

Answer 2

HERE IS YOUR ANSWER

Fusion occurs when atoms are heated to very high temperatures, causing them to collide at high velocity and fuse together. When two light nuclei collide to form a heavier nucleus the process releases a large amount of energy. The most practical fusion reaction uses isotopes of hydrogen named “deuterium” and “tritium”.
