Gaseous diffusion

Gaseous diffusion is a possibly method for enriching uranium experimented with by Henry V. FitzBelmont. The only gas found effective for it is the highly toxic uranium hexafluoride. FitzBelmont mentioned this technique when he attempted to pitch to Jake Featherston the idea of funding a project to build an atomic bomb. Since he could not guarantee that gaseous diffusion would be effective, Featherston refused to grant him the resource allocations he had requested.
