Very interesting reading, but I fear you are right - the method is probably too expensive - yet - for household use.

It states it can turn on and off as often as desired (i.e. every time you open the tap, then maybe x seconds after flow stops), AND it lasts for 30000 hours. 30000 hours of water flow is a two digit year life, if not more.

About the LED technology - are you saying that UV-C LED lamps are on the way? As stated in the article - hot lamps increase the amount of sediment left on the quarts, meaning it needs to be cleaned more often. A lower temperature means less cleaning. Bacteria and virus must be nuked, but not baked, as the UV-C light destroys the DNA of the bacteria, disabling their reproduction.
