And the actual paper is behind a paywall. You can read the first page, which basically says "700W magnetron, 20 micronewtons thrust, knife-edge balance and torsion balance in a vacuum, and we get the most output up in the regime where our balance isn't very accurate."

I remember all the bullshit hype around Fleischman & Pons and I, too, will remain skeptical for quite some time to come.
