Scientists used an unconventional method of creating nuclear fusion to yield a record-breaking burst of energy of more than 10 quadrillion watts, by firing intense beams of light from the world's largest lasers at a tiny pellet of hydrogen.
Researchers at the Lawrence Livermore National Laboratory in Northern California said they had focused 192 giant lasers at the National Ignition Facility (NIF) onto a pea-size pellet, resulting in the release of 1.3 megajoules of energy in 100 trillionths of a second — roughly 10% of the energy of the sunlight that hits Earth every moment, and about 70% of the energy that the pellet had absorbed from the lasers. The scientists hope one day to reach the break-even or "ignition" point of the pellet, where it gives off 100% or more energy than it absorbs.
The energy yield is significantly larger than the scientists expected and much greater than the previous record of 170 kilojoules they set in February.
The researchers hope the result will expand their ability to research nuclear fusion weapons, the NIF's core mission, and that it could lead to new ways to harness energy from nuclear fusion — the process that powers the sun and other stars. Some scientists hope that nuclear fusion could one day be a relatively safe and sustainable method for generating energy on Earth.
"This result is a historic step forward for inertial confinement fusion research, opening a fundamentally new regime for exploration and the advancement of our critical national security missions," Kim Budil, the director of Lawrence Livermore National Laboratory, said in a statement.
