Front claws: heat transfer and removal ◊ Innovative heat transport from devices Negafans, VFD fans, MEMS fans, electrostatic fans (Kronos), inkjets, micro-Stirlings, quantum-tunneling thermal diodes,…and heat pipes! Diamond, carbon fiber, carbon nanotubes,… ◊ Liquid cooling? (could be dry-chip; liquid at backplane) ◊ At least thoughtfully designed airflow! ◊ Extremely efficient air-handling and cooling Passive, then semiactive, then active Economizers, passive latent heat exchangers,… ◊ Heat-driven HVAC based on onsite trigeneration, system η ~0.90–0.93, ultrareliable, eliminate UPS
Morsels, scraps, broth, aroma ◊ Building envelope, α, ε, shading, massing, elevators ◊ Lighting (6–7 connected W/m 2 , ~1–3 W/m 2 when occupied, lights-off when only machines are present) ◊ What temperature and humidity range does the equipment actually require? (e.g,. most modern networking eqt is designed for 20–80%, so 30–70% makes reasonable allowance for sensor errors, etc.; but some data centers strive for 50±5%) ◊ Load diversity, thermal time constants ◊ Dynamic time/space matching of cooling to actual instantaneous needs (JCI, HP) ◊ Perhaps innovative fluid-handling devices ◊ Lots of little savings multiply: e.g., 0.9 10 = 0.35
