      Projections of Earth's Technosphere: Luminosity and Mass as Limits to Growth
      Earth remains the only known example of a planet with technology, and future projections of Earth's trajectory provide a basis and motivation for approaching the search for extraterrestrial technospheres. Conventional approaches toward projecting Earth's technosphere include applications of the Kardashev scale, which suggest the possibility that energy-intensive civilizations may expand to harness the entire energy output available to their planet, host star, or even the entire galaxy. In this study, we argue that the Kardashev scale is better understood as a "luminosity limit" that describes the maximum capacity for a civilization to harvest luminous stellar energy across a given spatial domain, and we note that thermodynamic efficiency will always keep a luminosity-limited technosphere from actually reaching this theoretical limit. We suggest the possibility that an advanced technosphere might evolve beyond this luminosity limit to draw its energy directly from harvesting stellar mass, and we also discuss possible trajectories that could exist between Earth today and such hypothetical "stellivores." We develop a framework to describe trajectories for long-lived technospheres that optimize their growth strategies between exploration and exploitation, unlike Earth today. We note that analyses of compact accreting stars could provide ways to test the stellivore hypothesis, and we more broadly suggest an expansion of technosignature search strategies beyond those that reside exactly at the luminosity limit.

    Clifford D. Simak had a “life blanket” in one of his stories (see link). He reused the idea in my current read (“So Bright the Vision”) in which the main character mentions the concept was used by a obscure SF author, hundreds of years before, name long lost. http://www.technovelgy.com/ct/content.asp?Bnum=1453

    Well, going to have to be doubly careful buying Audible titles. Check for both abridged books and now books that don’t use ACTUAL HUMAN NARRATORS.
