Re: The Singularity?
You mean in terms of electrical power? Well, part of it's increased efficiency, supposedly, along with new sources. Eventually, you get to the "all the power of an entire sun is captured and used" level. Not sure how much stock in I put in Kardeshev's work.
Another aspect of the Singularity is "nanotech". Of course, the nanotech of science fiction is often just another name for magic, as the little buggers seem to run without needing power or generating any waste heat.
