The major advantage is that it uses cheaper D-D fusion but at a much lower size then using magnetic confinement.
Well you could use any device powerful enough to ingite so laser, ion beam, or a fission primary. Steinhaus’s favoured method is a light ion beam.
I think Stienhaus quoted the driver would have to deliver between 50-100mj per shot.
This is the picture he uses to illiustrate it.
