The power in the Stars

The National Ignition Facility in California was dedicated in March 2009.

Like the cathedrals of antiquity, it is built on an unrivaled scale with unmatched technology, and it embodies a scientific doctrine that, if confirmed, might lift civilization to new heights.
In theory, the facility’s 192 lasers — made of nearly 60 miles of mirrors and fiber optics, crystals and light amplifiers — will fire as one to pulverize a fleck of hydrogen fuel smaller than a match head. Compressed and heated to temperatures hotter than those of the core of a star, the hydrogen atoms will fuse into helium, releasing bursts of thermonuclear energy.

In February, NIF fired its 192 beams into its target chamber for the first time, and it now has the world’s most powerful laser, as well as the largest optical instrument ever built. But raising its energies still further to the point of ignition could take a year or more of experimentation and might, officials concede, prove daunting and perhaps impossible.
For that reason, skeptics dismiss NIF as a colossal delusion that is squandering precious resources at a time of economic hardship. Just operating it, officials grant, will cost $140 million a year. Some doubters ridicule it as the National Almost Ignition Facility, or NAIF
“If fusion energy works,” he said, “you’ll have, for all intents and purposes, a limitless supply of carbon-free energy that’s not geopolitically sensitive. What more would you want? It’s a game changer.”

Dr. Moses, who was put in charge of NIF a decade ago in an effort to right the struggling project, said that a decade from now, as NIF opened new frontiers, no one would remember the missteps. He compared the project to feats like going to the Moon, building the atom bomb and inventing the airplane.
“Stumbles are not unusual when you take on big-risk projects,” he said.
Dr. Moses added that the stumble rule applied to cathedrals as well.
Having grown up in Eastchester, close to New York City, he noted that the Cathedral Church of Saint John the Divine, on the Upper West Side of Manhattan, was still under construction after more than a century. Is it worthwhile, despite the delays?
“Of course it is,” he said. Taking on big projects that challenge the imagination “is who we are as a species.”
