perhaps safire is suspected of ability that outperforms FF1 in its key goal : production of nuke accelerated ions. Its certainly simpler. All thats needed is a way to direct the ions, and safire beats FF1. Remember that plasmoid production en-mass is asserted to happen at all stars. There are no FF1 devices in space but there are lots of coronas, and thats all safire is, an artificial 1.8kW corona that naturally creates 10 MW spikes.
