The experiment, funded by the U.S. Navy, was aimed at verifying some interesting results that the late physicist Robert Bussard coaxed out of a high-voltage inertial electrostatic contraption known as WB-6. (The "WB" stands for Wiffle Ball, which describes the shape of the device and its magnetic field.)See earlier posts here and here for background.
An EMC2 team headed by Los Alamos researcher Richard Nebel (who's on leave from his federal lab job) picked up the baton from Bussard and tried to duplicate the results. The team has turned in its final report, and it's been double-checked by a peer-review panel, Nebel told me today. Although he couldn't go into the details, he said the verdict was positive.
"There's nothing in there that suggests this will not work," Nebel said. "That's a very different statement from saying that it will work."
By and large, the EMC2 results fit Bussard's theoretical predictions, Nebel said. That could mean Polywell fusion would actually lead to a power-generating reaction. But based on the 10-month, shoestring-budget experiment, the team can't rule out the possibility that a different phenomenon is causing the observed effects.
"If you want to say something absolutely, you have to say there's no other explanation," Nebel said. The review board agreed with that conservative assessment, he said.
The good news, from Nebel's standpoint, is that the WB-7 experiment hasn't ruled out the possibility that Polywell fusion could actually serve as a low-cost, long-term energy solution. "If this thing was absolutely dead in the water, we would have found out," he said.

Nebel and his colleagues have already drawn up a plan for the next step: an 18-month program to build and test a larger fusor prototype. "We're shopping that around inside the DOD [Department of Defense], and we'll see what happens," he said.
Nebel said some private-sector ventures are also interested in what EMC2 is up to, and that may suggest a backup plan in case the Pentagon isn't interesting in following up on WB-7.
For the time being, Nebel said his five-person team is getting by on some small-scale contracts from the Defense Department (including these three). "I've got enough to cover the people we've got, and that's about it," he said. "What we're doing with these contracts is trying to get prepared for the next step."
He's also waiting to see what the Obama administration will bring. Will the White House support EMC2's low-cost, under-the-radar fusion research program alongside ITER and the National Ignition Facility? "We just don't know," Nebel said.
Polywell Fusion Moving Forward
