China set a record for the highest heat ever recorded. Scientists created a 70,000,000ºC "artificial sun". The record was for keeping the heat at a temperature five times hotter than the sun for more than 17 minutes. The heat was created in a nuclear fusion reactor. The reactor is part of a project called EAST. It reproduces the reactions that happen inside our sun. The scientists are developing the artificial sun to get a near-endless supply of clean energy. The EAST project has cost more than $950 billion. That will be over $1 trillion later this year.
Scientists have tried for decades to develop nuclear fusion. It is the best way to produce clean energy. The process needs no fossil fuels and leaves no dangerous waste. If scientists can make it work, the world will be greener and cleaner. It could also mean lower fuel bills. Nuclear fusion technology is still not advanced enough to be a global industry. However, a nuclear fusion expert says the EAST project is an important step. He said: "The recent operation lays a solid scientific and experimental foundation towards the running of a fusion reactor."
Back to the artificial sun lesson.
