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。

OK, so after these decades of work, how close is the fusion industry to reaching net energy?

好的，经过这几十年的工作，聚变行业离净能源还有多远？

But even if we were second, the question is not just to get to net energy, right?

但即使我们是第二名， 问题也不仅仅是获得净能量， 对吧？

So achieve net energy gain from the fusion experiment.

因此，从聚变实验中获得净能量增益。

In that practical constraint put on top of just beyond net energy, I'm absolutely certain TAE will be first.

在超出净能量之上的实际限制中，我绝对肯定 TAE 将是第一位的。

But like everybody else in fusion, TAE hasn't managed to produce net energy yet.

但是和聚变中的其他人一样， TAE 还没有设法产生净能量。

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。

There is consistent success now at or almost at the point where you need to beat it to get the net energy out.

现在或几乎在你需要击败它以释放净能量的时候， 会有持续的成功。

And last year, a US government-backed project got the closest anyone has to producing net energy with a fusion system that uses lasers instead of magnets.

去年，一个美国政府支持的项目通过使用激光而不是磁铁的聚变系统获得了最接近于产生净能量的项目。

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。

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。
