Scientists have generated fusion energy before.

科学家们以前已经生产过核聚变能。

Right now, we are the largest producer of fusion energy in the world.

此刻 我们就是世界最大的混合能源生产商。

And then they still promise fusion energy by 2030 or something.

然后他们仍然承诺在 2030 年左右实现聚变能源。

She now runs a consultancy called Fusion Energy Insights.

她现在经营着一家名为Fusion Energy Insights的咨询公司。

But the excitement about fusion energy is not limited to big government research projects.

但对聚变能的兴奋并不局限于大型政府研究项目。

So what makes this wave of enthusiasm for fusion energy any different to the ones we've had before?

那么，是什么让这波对聚变能的热情与我们之前的热情有所不同呢？

Fusion energy, generated by merging atomic nuclei, could solve many of the  world's energy problems while, at the same time, reducing our environmental footprint.

通过合并原子核产生的聚变能可以解决世界上的许多能源问题，同时减少我们的环境足迹。

General Fusion's reactor would create brief bursts of fusion energy, an approach they hope will achieve net gain more easily than a tokamak.

General Fusion 的反应堆会产生短暂的聚变能量爆发，他们希望这种方法比托卡马克更容易实现净增益。

There's no doubt that if fusion energy was to become a reality, it could be a game changer for our fight against climate change.

毫无疑问，如果聚变能成为现实，它可能会改变我们应对气候变化的斗争。

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。

But I mean, I still, I still think there's a possibility that you see fusion energy as a part of the global energy mix in the 2040s.

但我的意思是， 我仍然，我仍然认为你有可能将聚变能源视为 2040 年代全球能源结构的一部分。

Consisting of three main buildings, the project is centred around the tokamak, a magnetic chamber that will contain the plasma created when particles are heated to over 150 million degrees Celsius and collide to produce fusion energy.

该项由三栋主要建筑组成，以托卡马克为中心，托卡马克是一个磁性装置，可以容纳当粒子加热到超过 1.5 亿摄氏度并碰撞产生聚变能时产生的等离子体。

And I don't like that too much because I'm afraid that if there are so many promises not kept that this would not be positive for fusion energy in general.

我不太喜欢这样，因为我担心如果有那么多承诺没有兑现，那么总体而言这对聚变能来说不会是积极的。
