1. A method, comprising:
passing infrared energy through a band-pass filter to produce a spectral energy pattern, wherein the band-pass filter is composed of 85 to 90 weight percent aluminum, and 10 to 15 weight percent of one or more of Si, Fe, Cu, Mn, Mg, Cr, Ni, Zn, Ti, Pb, and Sn; and
treating a quantity of water comprising ions with the spectral energy pattern, wherein the spectral energy pattern is tuned to reduce a liquid-vapor interfacial tension of the water.
