Polywell containment has been around for a while now; the Department of Defense started funding research into it in 1983, and according to the wikipedia article I linked, in 2005 Robert Bussard's research team achieved 10⁹ fusion events per second. The Navy appears to be impressed with their results, given that they're continuing to fund the research to the tune of several million dollars a year; apparently the granting of this funding is based on peer-reviewed results, so there's that.

It looks to me like Famulus is aiming to reproduce Bussard's results with the WB-6 design, which seems like a reasonable way of going about it.
