Paragraph 2
Scientists around the
have been trying for
to develop nuclear fusion. They say it is the best
to produce clean energy. The nuclear fusion
needs no fossil fuels and leaves behind no dangerous
. If scientists can make it work, the world will become
and cleaner. It could also mean lower fuel bills. EAST set the new record in a laboratory. Nuclear fusion
is still not advanced enough to become a global industry. However, researcher Dr Gong Xianzu, a nuclear fusion expert, says the EAST project is an
step. He said: "The recent operation lays a
scientific and experimental foundation towards the
of a fusion reactor."
