Scientists at the Lawrence Livermore National Laboratory are trying to use the world’s largest laser to Create Star on earth. This is the nuclear fusion reaction which will emit nearly limitless energy. Every body knows that sun and other stars emits energy for millions of years. Their thermonuclear fusion converts hydrogen to helium and vice versa continuously for 1 to 10 Billions year. If Scientist at Lawrence Lab, succeed, We will have renewable, cheap and endless amount of energy.
In an attempt to create a star on Earth, scientists are using the world’s largest laser at the Lawrence Livermore National Laboratory, California. The laser is roughly the size of three American football fields to set off a nuclear reaction so intense that it will make a star bloom on the surface of the Earth. The world’s largest laser is used to create a controlled fusion reaction and scientists hope that it will eventually result in “nearly limitless” energy for humanity.
This summer, the Lawrence Livermore National Laboratory will fire a mile-long laser beam that split it into 192 smaller beams, and focus the beams on a pinpoint of deuterium and tritium. Deuterium and tritium are the reactive hydrogen isotopes that can be extracted from seawater. The laser heat will fuse those isotopes together in reaction that at 100 million degrees Celsius which is more than five times hotter than the centre of the sun. According to CNN report, the fusion reaction is expected to be so intense it will really create a tiny star.
If the experiment by Livermore works and proves that lasers can create the same type of controlled fusion reactions that take place in the sun, it could lay concrete on the way for profitable fusion power plants. According to the lab, one gallon of seawater could provide the same energy as 300 gallons of gasoline. According to Livermore, the experiment is not harmful. A slight radioactive danger is there but the lab has encased the capacity in concrete walls that are two meters thick, just in case. The 100 million-degree-Celsius tiny star which will be created will die in 200 trillionths of a second. Lynda Seaver, the spokeswoman for the project said, there is no way it can explode: “The [worst possible] accident is, it doesn’t work.”
Bruno Van Wonterghem who is manager of the project, which is called the National Ignition Facility told CNN, “We have a very high confidence that we will be able to ignite the target within the next two years,” [thus proving that controlled fusion is possible. That would put the lab a step closer to] “our big dream, which is to solve the energy problems of the world.”
