What are the challenges of nuclear fusion?

What are the main challenges of nuclear fusion?

The main challenges of nuclear fusion include achieving the necessary temperatures, maintaining plasma stability, and managing energy input versus output.

Why is achieving high temperatures so difficult?

Achieving high temperatures is difficult because it requires overcoming significant energy barriers to initiate and sustain the fusion reaction.

What about plasma stability?

Plasma stability is challenging because the hot plasma must be contained without touching the reactor walls, which can lead to instabilities.

Are there any advancements in fusion technology?

Yes, there have been advancements such as improved magnetic confinement techniques and experimental reactors like ITER.

How long until we can use fusion as a power source?

It's hard to predict, but many experts believe we could see practical fusion power within the next few decades.
