Has anyone analyzed the nuclear pulse propulsion sail mentioned in the Dark Forest trilogy? The 1950's proposal was to carry nuclear explosives on a manned rocket and throw them out the back one by one. Cixin Liu's variation, for a lightweight, one-way probe, would preposition thousands of nukes throughout the solar system, and launch a thin radiation sail on a trajectory that flies through each detonation in sequence.
I assume there's some fatal flaw to this, but it takes more domain knowledge to identify it than I'm familiar with.
