Saving heat until you need it | MIT Energy Initiative
MIT researchers have demonstrated a new way to store unused heat from car engines, industrial machinery, and even sunshine until it''s needed. Central to their system is a "phase-change" material that absorbs lots of heat as it melts and releases it as it resolidifies. Once melted and activated by ultraviolet light, the material stores the ...
