Scientists in the United States have achieved a net energy gain from nuclear fusion for a second time.

美国科学家第二次从核聚变中获得净能量增益。

So achieve net energy gain from the fusion experiment.

因此，从聚变实验中获得净能量增益。

What needs to happen is the scientists need to figure out a way to now improve that energy gain.

现在需要做的是， 科学家们需要找出一种方法来改善能量增益。

Well, scientists at a Department of Energy lab in California have figured out how to successfully produce a nuclear fusion reaction with a net energy gain.

加州能源部实验室的科学家们已经找到了如何在成功产生核聚变反应的情况下获得净能量的方法。

In order for fusion energy to play a real role in achieving that net zero 2050 target, we're going to have to see net energy gain.

为了使聚变能在实现 2050 年净零目标方面发挥真正作用，我们将不得不看到净能源增益。

So rather than an energy gain of 1.5 that we've just seen, they want an energy gain of 30 or a hundred times the energy put in.

因此，他们想要的不是我们刚刚看到的 1.5 的能量增益，而是输入能量的 30 倍或 100 倍。

If we're still struggling to see net energy gain by 2032, 2033, 2035, really the, you're running out of time before 2050. And so I think you might start to see some of the enthusiasm and cash drain away.

如果我们仍在努力争取到 2032 年、2033 年、2035 年实现净能源增长，那么到 2050 年你的时间已经不多了。 所以我认为你可能会开始看到一些热情和现金流失。
