Asignificant breakthrough has recently occurred in the race to produce clean energy. Scientists at a laboratory in the United States were able to create a fusion reaction that produced more energy than was required to make it. Experts around the world agree that this incredible development proves that fusion power can one day be a practical energy option.
Fusion power is a type of nuclear energy source like fission power, which is currently a common source of energy across the globe. While fission power involves splitting a large atom to produce energy, fusion power creates energy by combining smaller atoms together. It makes energy the same way the Sun and stars do. One important thing to note is that fusion power doesn’t create harmful long-term radioactive waste and is unlikely to cause dangerous power plant meltdowns like fission power. That’s why fusion power has been described as the “holy grail” of sustainable energy.
Despite this critical development, there are still many obstacles to get over before fusion power becomes a reality. For one thing, the energy produced in the above- mentioned experiment was just enough to boil a few water kettles. It is incredibly difficult to sustain a fusion reaction.
Temperatures need to be higher than the Sun’s center, and the pressure should also be greater than the Earth’s atmosphere before atoms will merge, not to mention the costs of building and maintaining all the highly-technical equipment. Still, many in the scientific community are optimistic about what the future of fusion power holds.

最近,在製造乾淨能源的競賽中有一項重大突破出現 了。美國一間實驗室的科學家得以製造出核融合反應,其產 生的能量比要製造出該反應所需的能量還多。全世界的專家 皆贊同,這令人難以置信的發展證明了核融合能源有朝一日 會是能實際運用的能源選擇。
核融合能源跟核分裂能源一樣是一種核能源,核分裂能 源是一種目前在全世界很常見的能量來源。核分裂能源需要 分裂一個大原子來產生能源,核融合能源則是藉由結合較小 的原子來產生能源。其製造能源的方式跟太陽和恆星一樣。 有一件值得注意的重要事情是,核融合能源不會產生有害的長期放射性廢棄物,也不太可能像核分裂能源一樣造成危險 的核電廠熔毀。那就是為什麼核融合能源被形容為永續能源 的「聖杯」。
儘管有了這項關鍵性的發展,在核融合能源成真以前還 是有許多障礙要克服。首先,在上述實驗中所產生的能源只 夠用來煮幾壺水。要維持核融合反應極度困難。在原子融合之 前,溫度須高於太陽中心的溫度,而壓力也應該要比地球大氣 還大,更別提建造和維護所有高技術性設備的花費。然而,科 學界很多人還是對於核融合能源未來的發展樂觀以待。
