  Motivated by recent observations of high-velocity, highly ionized winds in
several QSOs, models of purely continuum-driven winds launched from
approximately 200 GM_{BH}/c^2 are presented. Launching conditions are
investigated, as well as the observational signatures for a variety of initial
conditions and illuminating continua. While we verify that continuum-driven,
highly-ionized outflows reach the observed velocities for L/L_{Edd} >~ 1,
independent of the incident spectral shape, such winds are too highly ionized
to exhibit the observed absorption features when launched with an AGN continuum
(in fact, such winds are so ionized that they are driven primarily by electron
scattering). If the wind is instead illuminated with a blackbody continuum
originating from an optically thick shield, the gas is too weakly ionized and
does not produce high energy absorption features. If high-velocity,
high-ionization winds are truly launched from very near the black hole, such
winds must be launched under other conditions or via other processes; we
summarize some possibilities.
