alt Hacker NewsI doubt half the power is to the transmitter, and radio efficiency is poor -- 20% might be a good starting point.

Entirely depends on band, at 10GHz more like 40%, at lower frequencies more, for example FM band can even go to 70%
Is the SpaceX thin-foil cooling based on graphene real? Can experts check this out?
"SmartIR’s graphene-based radiator launches on SpaceX Falcon 9" [1]. This could be the magic behind this bet on heat radiation through exotic material. Lot of blog posts say impossible, expensive, stock pump, etc. Could this be the underlying technology breakthrough? Along with avoiding complex self-assembly in space through decentralization (1 million AI constellation, laser-grid comms).
