Question

Advantages of harnessing energy derived from nuclear fusion are all of these except:

a. An immense amount of heat energy is generated
b. Minute source (quantity) of raw material is required for the reaction
c. No greenhouse gases are emitted during energy production
d. Current energy input is smaller than the energy output
e. Relatively small amounts of radioactive waste are produced

Answer 1

The incorrect statement among the advantages of nuclear fusion is that current energy input is smaller than the energy output. In reality, it is still a challenge to achieve a net positive energy output in fusion reactions.

Step-by-step explanation:

The advantages of harnessing energy derived from nuclear fusion are immense, including the production of a significant amount of heat energy, requiring only a minuscule quantity of raw material for the reaction, and emitting no greenhouse gases during the energy production process. However, not all points listed are correct. Specifically, current energy input is not smaller than the energy output, which is the incorrect statement among the options given. In fact, achieving a reaction where the energy output exceeds the energy input is one of the key challenges in fusion research. Additionally, nuclear fusion does not produce wide-ranging radioactive isotopes seen in fission, hence resulting in relatively small amounts of radioactive waste. However, the fusion process still generates some radioactive waste due to neutrons impacting the containment vessel over time.
