Scientists Create Nuclear Fusion Using 500 Trillion Watts Of Laser Energy
Researchers at the Lawrence Livermore National Laboratory in
California have been struggling to create nuclear fusion using lasers.
Nuclear fusion is the process by which the Sun generates electricity and
the researchers have been trying to replicate it since 2010 with little
success until recently.
On February 12th, 2014, Dr. Omar Hurricane published a report that
stated his teams’s success in the near impossible task of creating
nuclear fusion without the detonation of a nuclear warhead. Harnessing
this energy has been something that scientists have been trying to
achieve for a long time, with nuclear fusion being called the holy grail
of green energy. There are labs that have produced short sporadic
events of laser powered fusion to work, but the procedures always
required more energy than they produced.
Dr.Hurricane and his colleagues changed all of that by using the
laser at the National Ignition Facility (NIF). A total of 500 trillion
watts of laser energy was focused into a container through an aperture
the size of a pencil and resulted in the first instance of a nuclear
fusion reaction that produced more energy than it consumed, in the
history of mankind. While this story sounds like we might have free
energy in the very near future, there is some bad news. The resulting
reaction was not only brief, but the final step which causes the
reaction to last (where the reaction feeds upon itself to create energy
on its own), did not take place. Another point worth noting is that
while the fuel generated more energy than it absorbed, only a small
fraction of the lasers’ energy was absorbed, making the process still
energy negative.
It may still be a long time till our homes are endlessly powered by
lab-born stars, but by fusing hydrogen into helium, we are certainly
one step closer to the ultimate goal. Dr. Hurricane is uncertain if the
NIF is capable of reaching ignition, but the latest achievement has
certainly inspired him to carry on.
