A good way to store thermal energy is by using a phase-change material (PCM) such as wax. Heat up a solid piece of wax, and it''ll gradually get warmer—until it begins to melt. As it transitions from the solid to the liquid phase, it will continue to absorb heat, but its temperature will remain essentially constant. - Download [PDF]
