31. Porous material
A. Make an object porous or add porous elements (inserts, covers, etc.).
Example:
• Use a thin film structure like a winter cover on a tennis court.
B. If an object is already porous, fill the pores in advance with some substance.
Example:
• To avoid pumping coolant to a machine, some of its parts are filled with a porous material soaked in coolant liquid. The coolant evaporates when the machine is working, providing short-term uniform cooling.
• Float a film of bipolar material on a reservoir to limit evaporation.
