The lasers fuelling hopes of unlimited, clean nuclear energy

Via The Independent:

Scientists in California said on Wednesday night that they have for the first time managed to release more energy from their nuclear fusion experiment than they put into it, which marks a critical threshold in eventually achieving the goal of a self-sustaining nuclear-fusion reaction.

Points:

• “Researchers involved in the Nuclear Ignition Facility (NIF) at the Lawrence Livermore National Laboratory said that they have used 192 laser beams to compress a tiny fuel pellet less than half the diameter of a human hair in such a way that it triggered the net release of energy by nuclear fusion.”
• “The other approach is to build a complex magnetic “bottle” to hold the hot, electrically charged plasma of the fuel in place.”
