    Heads - Calcium(?) build up

    Vinegar would probably do it, but be careful it can etch and it I suppose it might not play nicely with some sealants.

    well, this is broken to the point of unuseability...

    My bookmark for the old site http://forums.sailinganarchy.com/index.php?/discover/49/ used to bring up a compact list of new content but without any PA content. The bookmark doesn't work anymore and I don't see a similar feature in the new version. Forums -> New Posts isn't compact and a lot of...

    Ukraine

    NRA advertising and Jan 6 aside? The situation in Donbas from 2013-14 is complicated but the armed part of has been an active Russian operation sparked by the fall of Yanukovych. More agitation and invasion than counter-revolution, I think.

    These folks put out a daily assessment that while imperfect is easily digestible. No worse than perseverating and it takes less time.  https://www.understandingwar.org/publications

    Ukraine

    ... and "Henry" is a pro because bombing Cambodia worked so well for peace? Davos is where "very serious people" gather. I get the feeling that most of the very serious people in policy and government believe that Ukraine is "naturally" a suzerainty of Russia. I think they are full of shit. ...

    Desalination @ 1/10 Power, 1/2 Cost wins MIT competition

    Thanks. I got that. I was wondering about its relation to a small centrifugal pump as suggested by Keith. ~~~ Our setup is audible all over the boat but I've never found it objectionably loud. The 12v pump drones and there's a thump when the piston shifts. Ours is all discrete parts that we...

    Desalination @ 1/10 Power, 1/2 Cost wins MIT competition

    I bought mine in 1999 and they didn't even have those features. Good to hear my envy was misplaced. :)

    Monkeypox

    Yes... The comedy writes itself but it's not a morality play. For the moment cases in the EU and NA are associated with "MSM" (yet another reason to avoid the news?), but that's not typical of the disease in Africa. It kills kids and young adults there. the weighted average of the median age of...

    solar mppt controller mounted sideways?

    ^^^ That seems right to me. It looks like they want it on a vertical surface with air flow as indicated. If I had to orient it differently I'd add in a pc fan.

    Desalination @ 1/10 Power, 1/2 Cost wins MIT competition

    When full time cruising our Spectra was ~~wonderful~~. Seriously. In good solar weather we made water with excess solar and in bad solar weather we made water while charging the batteries. For me, a smaller, quieter system would be nice but simplification and improvements of the cleaning...

    digital switching - unforeseen risk

    Aren't surge suppressors wear items? I wonder if there are implications of a single, whole house, device in terms of how quickly it might wear and how much of a PIA it would be to replace.

    Ukraine

    Maybe but you probably heard correctly. It is a story that RUS released and lots of outlets picked up. Here's one take: https://www.washingtonpost.com/world/2022/05/19/russia-laser-weapon-zadira-peresvet-ukraine/ A senior Russian official told state media on Wednesday that a state-of-the-art...
