39. Nuclear Fusion
Nuclear fusion is a process that happens when
light atoms join together to form a heavier
. When this happens, a large amount of energy
released. This is the same process that powers
sun and other stars in the universe. Inside
sun, hydrogen atoms fuse together to make helium,
heat and light that reach the Earth.
Scientists
long dreamed of using nuclear fusion on Earth
a clean and powerful energy source. Unlike fossil
such as coal or oil, fusion does not
greenhouse gases that cause climate change. It also
much less radioactive waste than nuclear fission, which
used in today's nuclear power plants. Fusion fuel,
hydrogen, is also easy to find in water
other natural sources, making it a nearly limitless
of energy.
However, creating fusion on Earth is
difficult. To make atoms fuse, scientists must heat
gas to over 100 million degrees Celsius, hotter
the sun's core. At this temperature, the atoms
so fast that they can overcome their natural
and fuse together. Building a machine that can
contain such high temperatures is a huge challenge.
the world, large projects like ITER in France
trying to make fusion power possible. If scientists
, fusion could change the future of energy. It
give us clean, safe, and almost endless electricity
homes, factories, and cities.
In short, nuclear fusion
the energy of the stars. It promises great
for humanity, but we still need time, technology,
teamwork to make it work on Earth.
