Alcubierre (warp bubble) Drive and high radiation levels

Mark Anderson's article Warp 9, and don't spare the radiation in the 2007-09-22 issue of NewScientist (p. 8-9) represents high radiation levels as a problem for a hypothetical vessel using such a drive.

But, radiation could be an energy source, if we can find ways to harvest it. Perhaps just as there have been innovations in the shape of the proposed bubble to achieve better theoretical efficiencies, the same technique could be used to either reduce the amount of radiation reaching the vessel, or even better channel some or all of it in such a way that it powers the drive (making it — somewhat — analogous to a scramjet in atmospheric propulsion.

That's My 1/50th.
