太陽輸出光與熱，因為內部時刻進行熱核聚變反應。
科學界只要可以掌握核聚變供應能源的技術，意味將來人類可以世世代代擁有無限而且清潔的能源。
中國的科研團隊近年在「人造太陽」技術發展有新的突破，國家原子能機構自主研製的中國環流器2M裝置在成都建成，標誌着這台核聚變裝備正式投運。
目前核電站普遍應用核裂變反應發電，這類核電廠帶來穩定的電力供應，不過運作時會產生有害的放射性廢棄物及需要處理核廢料。
至於核聚變發電帶來放射性污染較少，不會有碳排放等問題，因此確實是未來其中一個理想能源的選擇，取之不竭用之不盡的清潔能源。
中國在全球可控核聚變發展已經在世界前列。
Alternative and clean energy solutions are becoming more necessary, especially as we worry about the future of the planet and issues around the use and extraction of oil and gas. A research team in China has achieved new breakthroughs in artificial sun technology.
The sun outputs light and heat through the internal thermonuclear fusion reaction. The China Circulator 2M device independently developed by the National Atomic Energy Agency was completed in Chengdu, marking the official commission of this new piece of equipment.
At present, nuclear power plants generally use nuclear fission reactions to generate electricity. This particular type of nuclear power plant brings a stable power supply, but also generates hazardous waste.
As for nuclear fusion power generation, there is less radioactive pollution and no carbon emissions, so it is one of the ideal energy choices for the future.
As long as the scientific community can master the tech behind nuclear fusion to supply energy, human beings of the future can gain from unlimited and clean energy for generations.
China is already at the forefront in the development of global, controllable nuclear fusion. And many countries are on their way to achieving similar breakthroughs of their own. But stigma and some may say misconceptions around nuclear energy, as well as the immense up-front investment, makes this a hard commitment.
As our world becomes ever more reliant on consistent and powerful sources of energy, nuclear development will play a pivotal role for years to come.
