Couple of nuggets from "Thermal Storage of Solar Energy", a conference compilation by Ouden:
1. Adding aluminum strips (1.6% by volume) cut heat addition/extraction time in paraffin PCM's fourfold.
2. SAT changes volume less than 5% over 20-80C, well within what hot-fill beverage packaging can handle.
