Fusion pulse rocket

Whilst the Saturnbros are awaiting Direct Fusion from Princeton, a few days ago various outlets have been relaying some press-releases about the FireStar from RocketStar. Where Direct Fusion is NERVA-ish, FireStar is Fusion-Enhanced Pulsed Plasma Electric Propulsion - so, more Orion-ish. The (boron) fusion is happening in its afterburner.

As Pixy pointed out yesterday, the device does spray ionising radiation all over the place. Keyword, in his Kiwi dialect: "ionising"; that is: not neutrons. (Yay boron!) Ions, we can handle, with magnets.

Now, I don't think anyone will allow RocketStar to use this to get us off of Earth, for the usual test-ban reasons. But limited Orion above the Van Allens might not face the same regulatory hurdles.

So first we need to get this stuff up there.
