What Is Nuclear Fusion And Why Is It Important?
Scientists announced that they have successfully created a nuclear fusion reaction which researchers have been attempting to do for decades. NBC News’ Hallie Jackson breaks down how this new technology could replace the way energy is made and potentially move away from the current usage of fossil fuels.http://nbcnews.to/SubscribeToNBC http://bit.ly/MoreNBCNews https://smart.link/5d0cd9df61b80 https://link.nbcnews.com/join/5cj/bre …http://nbcnews.to/ReadNBC http://nbcnews.to/LikeNBC http://nbcnews.to/FollowNBC

0.06 -> a really sunny day it's hot and bright
2.82 -> that's thanks to a process that happens
4.86 -> deep inside the sun called nuclear
7.379 -> fusion nuclear fusion is when you take
10.44 -> really light elements and smash them
13.74 -> together really hard to create heavier
16.139 -> elements and in that process there is a
19.32 -> little bit release of energy our sun
22.26 -> does nuclear fusion every single day and
24.779 -> that's how the Sun powers itself all
27 -> right it works like this two hydrogen
28.92 -> atoms moving really fast smashed
31.14 -> together and when they do the reaction
33.239 -> creates not just another element helium
35.52 -> but energy so if this happens all the
37.92 -> time in Stars why is our ability to do
40.079 -> the same thing here on Earth such a big
41.64 -> deal creating energy like this does not
44.16 -> create carbon so experts say it opens
46.92 -> the door to maybe ending the world's
48.66 -> dependence on fossil fuels this whole
50.82 -> process is called nuclear fusion and
53.28 -> it's sibling basically the reverse is
55.68 -> nuclear efficient that's how we create
57.539 -> nuclear bombs now and nuclear energy but
60 -> but creating energy that way leaves
61.98 -> behind radioactive waste plus there's
64.26 -> the risk of potential disasters like
66.54 -> what we've seen at Chernobyl or
68.04 -> Fukushima with Fusion it's the complete
70.14 -> opposite it you just hit one switch and
72.36 -> the whole thing shuts off and that's it
73.979 -> so nuclear fusion is a big deal but it
76.439 -> comes with the catch and it's a big one
78.479 -> this is not going to be a snap to scale
80.759 -> up a bunch of really smart people in a
82.979 -> lab with humongous special lasers made
84.84 -> this happen for a split second this time
87 -> after Decades of work and billions of
89.64 -> dollars to get from that to something
91.5 -> you can actually use when you flip a
93.36 -> light switch experts say that is still
95.52 -> decades away the amount of time it will
98.34 -> take to generate nuclear fusion as a
102.06 -> power source is very very very long
104.88 -> there's still so much work to do
109.02 -> thanks for watching our YouTube channel
