What about the singularity described in Eon(by Greg Bear) is this "type" of singularity possible?
Of course if you haven't read Eon you wouldn't understand:P
A Dyson "bubble"—has been proposed in which the shell would be complete, very thin, and non-rotating. It would consist of statites, or stationary solar sails, which reflected light onto collectors for use in external habitats. The entire mass of the structure would be approximately that of the...
What do you mean inefficient, currently Earth receives only one billionth of the sun's energy. With a Dyson sphere we would be able to collect nearly one hundred percent of the sun's released energy. Also if we used the asteroid belt as a source we would have ample material.
