Uses buckytube optics and fractaform architecture to allow a large orbital habitat around a host star. Differs from Smoke Ring in that the ring itself only acts as a scaffold for habitats. A diffusion disk requires advanced transapientech. There are a few throughout the MPA. See also Diffusion Sphere.

Type III Dyson Sphere that uses magmatter cabling, dynamic support structures, and fractaform architecture to allow maximal habitat around a host star. The sphere acts as a scaffold for habitats and computronium banks. Requires high transapient technology, and hence is more difficult to construct than the Type I dyson. There are three in Keterist space, two in the Solar Dominion, and three in the MPA. See also Diffusion Disk.
