Every time someone searches on Google, Yahoo, Bing, etc., and they click on a search result, the search engine sends over a string of text in the HTTP referrer letting me know what that user searched for.
In the last month I have started to see a bunch of searches for "nixie heat" "nixie clock temperature" and "how hot do nixie tubes get?" style queries. This is, as best as I can tell, completely new and now I've seen many searches along these lines.
Does anyone know why people are now searching for this?
And, if you found this post via Google - no, properly engineered nixie clocks shouldn't generate significant heat
