US LAB DEBUTS SUPER LASER

A US weapons lab on Friday pulled back the curtain on a super laser with the power to burn as hot as a star.

The National Ignition Facility's (NIF) main purpose is to serve as a tool for gauging the reliability and safety of the US nuclear weapons arsenal but scientists say it could deliver breakthroughs in safe fusion power.

NIF is touted as the world's highest-energy laser system. It is located inside the Lawrence Livermore National Laboratory about an hour's drive from San Francisco.

Equipment connected to a house-sized sphere can focus 192 laser beams on a small point, generating temperatures and pressures that exist at cores of stars or giant planets.

NIF will be able to create conditions and conduct experiments never before possible on Earth, according to the laboratory.

A fusion reaction triggered by the super laser hitting hydrogen atoms will produce more energy than was required to prompt "ignition," according to NIF director Edward Moses.

"This is the long-sought goal of 'energy gain' that has been the goal of fusion researchers for more than half a century," Moses said.

"NIF's success will be a scientific breakthrough of historic significance; the first demonstration of fusion ignition in a laboratory setting, duplicating on Earth the processes that power the stars."

If this is successfully reserched and funded, the implications, far beyond any military applications...are astounding. I'm not saying it will turn out this way, but it has the potential of being something our grandkids and great grandkids look back on as one of the most magnificent occurances of this cnetury, or our or their life times.

If these scientists can make fusion energy gathering a reality than almost any sum would be worth spending. Militarily, large lasers will be game-changing in so many areas. The consequences are most obvious right now in the area of missile defence.

Yes...but also in power applications the impacts would be enormous.

Cold fusion is still an avenue for exploration and I say full speed ahead there too...but this application at Livermore is producing results that are difficult to refute. It just needs to be made practical now.
