Scientists have spent the last 60 years trying to figure out the best way to create these conditions. Today, the frontrunner is a device known as a “tokamak,” a magnetic bottle in which the fuel, held at 100-200 million degrees Celsius, fuses, unlocking huge amounts of energy.
科学家们花了六十年时间试图找出创造这些条件的最佳方法。今天，领先的是一台名叫“托卡马克”的设备，该磁瓶温度高达1亿到2亿摄氏度，能使燃料在发生聚变的同时释放出巨大的能量。
