Why Don't We Have Nuclear Fusion Power Yet?

The video discusses the challenges and potential of nuclear fusion as a clean energy source. It compares fusion with current energy production methods, highlighting its advantages and technical hurdles. The video explores two main approaches to fusion: Inertial Confinement Fusion (ICF) and Magnetic Confinement Fusion (MCF), detailing ongoing experiments and future prospects like ITER.

What is one major environmental benefit of nuclear fusion compared to fossil fuels?

• It produces more carbon dioxide.

• It generates radioactive waste.

• It is less efficient than fossil fuels.

• It releases minimal carbon dioxide.

Which of the following is a drawback of solar and wind energy?

• They are more expensive than fossil fuels.

• They produce radioactive waste.

• They are non-renewable.

• They are inconsistent and can affect ecosystems.

What is the main challenge in achieving nuclear fusion on Earth?

• Finding enough uranium.

• Generating sufficient pressure and heat.

• Producing more carbon emissions.

• Creating radioactive waste.

What is the main difference between ICF and MCF approaches to nuclear fusion?

• ICF is more efficient than MCF.

• ICF uses lasers to implode fuel pellets, while MCF uses magnetic fields to contain plasma.

• MCF is used in nuclear weapons, while ICF is not.

• ICF uses magnetic fields, while MCF uses lasers.

What is a significant challenge in using magnetic fields for plasma containment in MCF?

• The magnetic fields are too expensive to generate.

• The plasma exhibits turbulent behavior.

• The magnetic fields are too weak.

• The plasma is too cold to contain.

What is the primary goal of the ITER project?

• To eliminate the need for magnetic fields in fusion.

• To reduce the cost of solar panels.

• To create a new type of nuclear fission reactor.

• To produce more energy than it consumes.

What is a potential issue with the materials used in fusion reactors?

• They become too cold to function.

• They can become brittle and radioactive over time.

• They are too expensive to produce.

• They are not strong enough to contain the plasma.
