Huge, high-energy facilities will attempt laser fusion in the next two years.
The ignition test lasted only 23 billionths of a second.
The scientists eventually focused the laser beam onto a 1 mm hydrogen target pellet, which produced more energy.

According to the British "Daily Mail" on July 16, the world's largest laser, the National Ignition Facility (NIF), recently completed an ignition test in California, USA. This is not only the most powerful laser pulse launch in human history, but also nuclear fusion energy. A milestone on the road to exploration, humanity hopes to use this method to obtain clean energy.
The duration of the test, which took place on July 5th, was only 23 billionths of a second, generating an energy equivalent to 500 trillion watts of electricity, more than 1,000 times the combined national electricity consumption in the same instant. MIT scientist Dr. Richard Petraso called "this is an amazing and exciting achievement", "because it created a situation in the laboratory that had only existed deep inside the planet."
The purpose of NIF construction is to generate heat and force similar to the star's inner core through laser fusion. It also shoulders the dream of a great clean energy. It is hopeful that humans will obtain nuclear fusion energy in the laboratory—a kind of almost inexhaustible. "Inexhaustible" clean energy, thus opening up a new era of energy. Scientists hope that this type of laser can become a "lighting device" for controlled nuclear fusion.
In the next two years, scientists will focus the 192 lasers on a 1mm hydrogen target pill to produce more energy.
In the United States, NIF is also related to weapons development projects, and nuclear fusion technology can also be used to make hydrogen bombs. However, opposition voices also exist. Environmental groups such as Greenpeace claimed that nuclear fusion research occupies funds that should be used to research mature technologies such as wind power. (Editor: Cai Donghai)
