To clarify: the device we used for the recent fusion run is a Farnsworth–Hirsch Fusor.
Ultimately we want to build and operate a Bussard Reactor (Polywell).
Building and operating the Fusor is a necessary step towards building the Bussard Reactor. The Bussard Reactor is an outgrowth of the Fusor, and the two devices have much in common.
While we build the Fusor, we are also building the Bussard Reactor. We have the first prototype of the magrid, and we are testing the superconducting cable.
