No comment on your actual question, but your last sentence reminded me of some research I saw an article about in the last few years premised on learning from nature and trying to address both power-delivery and heat-diffusion problems posed by "stacking" by accomplishing both with a fluid. Here's IBM's page for the research: https://www.zurich.ibm.com/st/energy_efficiency/redox_flow.html https://www.zurich.ibm.com/st/energy_efficiency/redox_flow.h... The intro section of one of their recent articles is a little meatier than the research site: https://ieeexplore.ieee.org/document/7967719 https://ieeexplore.ieee.org/document/7967719
