It replicates the Sun's fusion power that provides the light and warmth that enables life on Earth.

其复制太阳的聚变能量，为地球上的生命提供光和热。

ITER will demonstrate the scientific and technical feasibility of fusion power.

ITER 将论证聚变能的科学和技术可行性。

And therefore, you've got fusion power coming on the grid sooner.

因此，聚变能会更快地并入电网。

The aim is to study the possibility of building nuclear fusion power plants over the long term.

该项目旨在长期研究建造核聚变发电厂的可能性。

But there's still one big milestone we need to reach before fusion power becomes a reality, net gain.

但在聚变能成为现实之前，我们还需要达到一个重要的里程碑，即净收益。

Nuclear fusion powers the sun and scientists have been trying to develop it for decades in the hope of producing abundant clean energy.

核聚变是太阳的能量来源，科学家们几十年来一直在努力开发它，希望能产生丰富的清洁能源。

Once it's perfected, fusion power will give us an unlimited supply of energy.

一旦完善，聚变能将为我们提供无限的能量供应。

Even the most optimistic scientists think that fusion power may not be developed for 50 years, if then, if ever.

即使是最乐观的科学家也认为聚变能可能在 50 年内不会被开发出来，如果那时，如果有的话。

And we produced 16 megawatts of fusion power at the time which is like a few wind turbines.

我们当时生产了 16 兆瓦的聚变功率，就像几个风力涡轮机一样。

Private companies, backed by billions of dollars of investment, are also racing to develop fusion power.

在数十亿美元投资的支持下，私营公司也在竞相开发聚变能。

Unfortunately, it doesn't mean that fusion power stations are just around the corner.

不幸的是，这并不意味着聚变电站指日可待。

We want someone to put electricity on the grid from a fusion power station as quickly as possible.

我们希望有人尽快将聚变电站的电力接入电网。

And they're a lot more optimistic about when they can get a working fusion power station up and running.

他们对何时可以启动并运行可正常运行的核聚变电站更加乐观。

And if we're going to get to a fusion powered future, we're probably going to need both the painstaking research and the risky new ideas.

如果我们要实现聚变动力的未来，我们可能需要艰苦的研究和冒险的新想法。

In a fusion power plant, you would shoot the same target over and over at about ten times a second, dropping a target in and shooting it with laser.

在核聚变发电厂，你会以每秒10次的速度反复射击同一个靶丸，把靶丸放进去，然后用激光射击。

Even the most optimistic fusion industry advocate would say that we're at least a decade away from the first prototype fusion power plant.

即使是最乐观的聚变工业倡导者也会说， 我们距离第一个原型聚变电厂至少还有十年的时间。

Stars, as you probably know are enormous fusion powered convection ovens that burn so hot at their cores that very large atoms can smash together and form even larger atoms.

正如你可能知道的那样，恒星是巨大的聚变动力对流炉，其核心处燃烧温度很高，以至于非常大的原子会分裂并形成更大的原子。

It's been at the centre of European efforts to develop fusion power, and despite its age, it's still at the cutting edge of what's possible in fusion today.

它一直是欧洲发展聚变能的中心，尽管年代久远， 但它仍处于当今聚变可能性的前沿。

But still, if we haven't even built a machine that makes more energy than it uses yet, how long is it going to be until there are actual fusion power stations?

但是， 如果我们甚至还没有制造出比它使用的能量更多的机器，那么真正的聚变电站还要多长时间？

And while many in the scientific community predict fusion power will take decades, some in the private fusion space believe we'll get there in just a few years, as soon as the 2030s.

虽然科学界的许多人预测聚变能需要几十年的时间，但私人聚变领域的一些人认为我们将在短短几年内实现，最快到 2030 年代。
