    Recyclable fiberglass is already under development for wind turbine blades.

    I would think metal would be too heavy.

    Guinea worm Dracunculiasis is a parasitic disease now nearly eradicated globally. About 3.5 million cases in 1981, in 20 countries. Reduced to less than 20 cases globally in 2022. There is no vaccine etc., this was all done by improving public sanitation.

    It was a particular goal for The Carter Center

    Guinea Worm Eradication Program at The Carter Center



    Led by ex-President Carter and wife Rosalynn. She died yesterday at age 96 (or so). The Carter Center continues its work.

    No better epitaph than eradication of a public health threat.

    I'd agree. Not my intention to write an exit summary here, but the Carters did many things beyond struggling with Presidency for 4 years. 'Habitat for Humanity' made (makes) major contributions that could be reviewed. Maybe it has been.

    I focused on what may be the world's largest nematode (certainly ranks highly in ickiness). The Human Enterprise does less to improve the low side of prosperity bell curve than improving its high side. Examples of dedication to the low side puts we who call ourselves ecologists to shame. Which sounds gloomy, but hard to escape that when Warriors die.

    They do plenty of the later, especially now that much journalism has been de-staffed. For another recent example, look at how many "news" outlets "reported" that the Earth's core sometimes reversed spin direction and went backwards, when the source report claim was actually much less dramatic.

    Though I suspect this latest subject case might also involve a lot of spell checker 'corrections'.
    Huh? That link shows me plenty of hits, even after weeding out the many unrelated non-satellite hits.

    After being offline for nearly a month, it will take me quite a while to catch up. But many of the hits I saw were dated the same day you posted that link.

    This plane in water after runway overshoot:

    US Navy removes fuel from plane that overshot Hawaii runway and is now resting on a reef and sand - ABC News

    U was actually surprised that it had not been brought to shore yet. Lots of electronic goodies in there.

    So the P8-A is a 737 airframe, which has a normal landing distance of about 5000 feet. Kaneohe Bay runway is >7700 feet. Reports at the time indicated bad weather conditions at landing, sooo ...

    A replacement plane has been brought in. Article does not mention a replacement crew :eek:

    Most platinum comes from deep mines around Rustenburg South Africa. I did not know that, and would still not but for:

    Elevator drops 650 feet at platinum mine in South Africa, killing 11, injuring 75 - ABC News

    An elevator with 86 inside was on the way up. But then it reverted to rapid descent. 11 dead 75 injured.

    ==
    I took a potash mine tour in New Mexico once. (smaller) elevator car to a similar depth I guess, about -2000 feet. Such elevators move very fast, but obviously normally decelerate at end of travel. It really is a whoosh though.

    I thought elevators have an automatic brake mechanism held open by the suspension cable.

    They are supposed to have automatic brakes. But these have sometimes suffered mechanical failure. In one case I read about very long ago, the brakes initially worked, but the weight of the cables falling on top the car overwhelmed them.

    One item about this incident writes:

    "The alert was raised shortly before 5 p.m. as the elevator "unexpectedly started descending," the company said in a statement. ...

    "Its rapid descent was stopped by the conveyance counterweight becoming trapped by the jack catches," it added.

    Jack catches are safety systems intended to stop elevators and underground trains from rolling back in case of an accident."
