This is such a petty nitpick that I'm almost ashamed of pointing it out, but oceans aren't heatsinks for hurricanes. What drives them in the first place is the disequilibrium between the atmosphere and ocean. That's why they form over large swaths of warm evaporating water and dissipate once they go inland. Here -> ftp://texmex.mit.edu/pub/emanuel/PAPERS/Amer_sci.pdf (ftp links don't work) is a great paper on the topic by Kerry A. Emmanuel.
Her backgrounder on the history behind super-massive black hole research was great for an interested outsider like me so thanks for the recommendation.
Plus thermodynamics at those conditions and scales are a lot less straightforward. On the one hand, intuitively, everything would heat up from below due to a combination of fluid friction and pressure instabilities, and lose energy via IR radiation during the long, rising adiabatic expansion. On the other hand, fluid mechanics is rarely intuitive. Seems so. She frequented on Brady Harran's Sixty Symbols and Deep Sky Videos if memory serves. I liked those a lot.She is definitely not a planetary scientist, I'll say that. Her deep space stuff, however, is fantastic.
