The evaporative approach will actually manage to do something that's generally impossible as it will actually cool down the air. Obviously this is the superior method to deal with hot dry air. The use-case described in the article however: >The east coast’s dry winter air, parched further by the radiators that can barely keep up with the chill, causes great discomfort to me and millions suggests they're trying to heat the space they're in. At which point you'll need to recover any heat lost by evaporation anyway.
