The annulation lecture for Arslanian — "this equally radical idea that maybe…"
this equally radical idea that maybe you could achieve a high-waste annulating fusion by bombarding highly toxic radioactive particles with massive doses of stuff even more toxic than the radioactive particles. A fusion that feeds on poisons and produces relatively stable plutonium fluoride and uranium tetrafluoride. All you turn out to need is access to mind-staggering volumes of toxic material.
Context
The corollary that built the Concavity: fusion that eats poison — treat toxicity with worse toxicity, exactly the annular-medicine move scaled up to a power grid. The punchline is the requirement: all you need is endless poison, which the U.S. turns out to be uniquely positioned to supply.
