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。

Four months ago, we used freaking laser beams to recreate the conditions inside of a star, achieving more energy out of a nuclear fusion reaction than we put in.

4 个月前，我们用超厉害的激光重建了恒星内部的环境，由核聚变产生的能量超过了我们输入的能量。

Scientists say they've successfully produced a nuclear fusion reaction, which replicates the processes that happen on the sun and that they may have found the holy grail of clean energy.

科学家称他们已经成功制造出核聚变反应，复制了核聚变发生在太阳上的过程，将其作为清洁能源的梦想或将变为现实。

Jennifer Granholm said that scientists in California managed to generate more energy from a nuclear fusion reaction that was used to start the process.

詹妮弗格兰霍姆说， 加利福尼亚的科学家设法从用于启动该过程的核聚变反应中产生更多能量。
