npub1f5crgpaqepu6rur2gx98hvjtxdh2v9dnw9gvl2yu4e5g4p7v3q2qvkhqzn (npub1f5c…hqzn) Naah, if you *really* want to prolong the sun's utility as a light/heat source, you lift most of its mass and bunker it in brown dwarves, then you turn what's left into a black hole. Using the brown dwarves to feed the accretion disk you can probably get very substantial mass conversion into energy rather than stopping at whatever fusion end-product a regular star will reach. So we should be looking for low-mass black holes with dim accretion disks in close proximity to brown dwarves.
