Why Aren't We Using Nuclear Fusion To Solve Our Energy Crisis?

The video explains the differences between nuclear fission and fusion, highlighting fusion's advantages such as less fuel requirement and no radioactive waste. However, it also discusses the significant challenges in achieving nuclear fusion, including high energy requirements, material constraints, and economic and social barriers. Despite these challenges, nuclear fusion remains a promising clean energy source for the future.

What is one major advantage of nuclear fusion over fission?

• Fusion requires more fuel than fission.

• Fusion produces radioactive waste.

• Fusion uses deuterium, which is abundant.

• Fusion is more expensive than fission.

Why is nuclear fusion not yet a reliable power source?

• It requires extremely high temperatures to initiate.

• It requires low temperatures to start.

• It produces more power than it consumes.

• It has low energy requirements.

What is a significant challenge in building fusion reactors?

• Reducing the cost of deuterium.

• Creating simple reactor designs.

• Producing low-energy neutrons.

• Finding materials that can withstand high temperatures.

What is a common public perception issue with nuclear power?

• It is considered the safest energy source.

• It is seen as a clean energy source.

• It is associated with radiation dangers.

• It is the cheapest energy source.

What is the potential benefit of mastering nuclear fusion?

• It will increase the risk of meltdowns.

• It will produce more radioactive waste.

• It will ensure an endless power supply.

• It will require more uranium.
