A heat rejection apparatus includes an object conducting heat to be rejected, with an absorptive material on the outside of the object. A water system deposits water on the absorptive material to wet the material to absorb heat from the object by water evaporation. A collector below the object directs excess water to a drain. An air delivery system directs air over the absorptive material on the object. The water system supplies enough water to keep the absorptive material wet, even with the evaporative losses of water, and carry dissolved solids to the collector.
