We point out that Dyson Spheres could also be built around white
dwarfs. This type would avoid the need for artificial gravity technol-
ogy, in contrast to the AU-scale Dyson Spheres. In fact, we show that
parameters can be found to build Dyson Spheres suitable –temperature-
and gravity-wise– for human habitation. This type would be much
harder to detect.
