The AviationWeek article even mentions that the LMSW team drew from Polywell: > "We also have a recirculation that is very similar to a Polywell concept," he adds, referring to another promising avenue of fusion power research. A Polywell fusion reactor uses electromagnets to generate a magnetic field that traps electrons, creating a negative voltage, which then attract positive ions. The resulting acceleration of the ions toward the negative center results in a collision and fusion. It's great that they've scoured even the non-mainstream ideas and incorporated them.
