Hot stuff: Lab hits milestone on long road to fusion power

With 192 lasers and temperatures more than three times hotter than the center of the sun, scientists hit—at least for a fraction of a second—a key milestone on the long road toward nearly pollution-free fusion energy.

Fusion breakthrough is a milestone for climate, clean energy

Scientists announced Tuesday that they have for the first time produced more energy in a fusion reaction than was used to ignite it—a major breakthrough in the decades-long quest to harness the process that powers the sun.

Fusion energy: NIF experiments show initial gain in fusion fuel

Ignition – the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel – has long been considered the "holy grail" of inertial confinement fusion science. A key step along ...

Laser sets records for neutron yield, laser energy

( -- The National Nuclear Security Administration's National Ignition Facility (NIF) has set world records for neutron yield and laser energy delivered from laser-driven capsules to an inertial confinement fusion ...

Livermore lab nears launch of fusion quest

Within the next week at a high-security building in Livermore, Calif., the size of a football stadium, scientists will hunker down to conduct an experiment backed by billions of dollars and promises to change the world's ...

World's largest laser completed

( -- The Department of Energy today announced that the National Nuclear Security Administration (NNSA) has certified the completion of the historic effort to build the world's largest laser.

Simulations uncover obstacle to harnessing laser-driven fusion

( —A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results and first-of-a-kind ...
