I don't, actually. :-)
I just wonder whether the relevant increase in radioactivity could ever be a
match for the "billion of deaths" preconised by GW and oil-peak

Orion Project does not have anything to do with a "cannon". For all
practical aspects, it is a pulse rocket like the V1, if I am not mistaken,
albeit an unconventional and large-scale one. See, e.g.,

In fact, as I said, only *very* marginally, by burning the environmental
carbon close to the launch area into CO2. More or less as a military nuclear
OTOH, isn't the "nuclear winter" effect supposed to cool the earth out of
the airborne debris generated by each launch?
