Google “turned the lights out” for earth hour.
But if you have an LCD screen, a black pixel draws more current than a white one, because you have to energize the pixel. The low-energy state is “clear,” which lets the backlight through, and gives you white. So this thinking is very CRT, very yesterday. Not Google-y at all.

I was poking around the blogdom — with the rise of science-y, i.e. non-diary (and, I suppose non-dairy) blogs, surfing the web has become interesting again — and ran across a link to How to Build a Cloud Chamber, and that reminded of the person that built the cloud chamber using a Starbucks cup. (Not sure if he was so vain, however.)
And that reminded me of the question I had back then — TRIUMF had a large, continuously-running chamber in the lobby of the visitors’ entrance last time I was there, and though nobody does it better, I’m sure there are other facilities with similar setups. Why not run a webcam showing it? I haven’t found one.
Second-best is video. Here’s one that shows the construction steps of a good one, and some tracks. That’s at the end, so there will be some anticipation.
