案。
When you look at the night sky,what you see are actually lots of“power plants(发电厂)”.Every
1 makes a huge amount of energy through nuclear fusion().For years,scientists have 2
to make this kind of energy.They need to make a "mini star"on Earth.Recently,some scientists made
a big step forward.
In February,the Culham Center for Fusion Energy in Oxfordshire,UK,doubled (a world
record 3 in 1997.The machine there,named Jet,used fusion engines()to make the 4
amount of energy as four wind turbines()make,reported The Guardian.
In the past,5 experiment could make more energy than what was used to start the fusion engine.
This new experiment,although only lasting five seconds,showed it's possible to make more power.
Another good thing about the experiment is that the reaction()6 when the equipment(
got too hot.This problem can be solved with cooling systems.Future fusion reactions may last much
longer than five seconds-minutes or even 7.
Why do we 8 so much about star power Fusion reactions would provide power to everyone on
Earth -enough for everyone to 9 for thousands or millions of years.They're also clean-they don't
produce carbon dioxide or radioactive(放射性的)waste.
You may wonder why fusion energy is so hard to make.Creating conditions similar to a star is not
easy.The machine must reach temperatures as high as 10 times 10 of the sun's core().
Even so,it's time to get excited about star power.If it can be successfully rolled out(),it will
be a landmark(里程碑)in human history.
