  • How much is 25 lbs. of fuel savings worth to you? How much is it worth to Boeing?

    United Airlines switched to lighter paper for in-flight use to save 11lbs source

    From that article:

    “With United Airline’s 4,500 daily departures, it made sense to cut 1 oz. from its in-flight magazine, and switch to a lighter paper (weighing 6.85 oz.) instead. What this means in a larger scale, says the Times, is that the airline is saving 170,000 gallons of fuel a year which amounts to $290,000 in annual fuel costs.”


  • It looks like this material is being used for interior cosmetic components, not load/stress bearing structures:

    While the sidewall panel project is awaiting additional unique tooling and funding, Boeing is exploring recycled carbon fiber for additional cabin components, such as sandwich panels, which Wynhof said are used all over the cabin in nonloadbearing structures that don’t need to have the same sound-dampening requirements as sidewall panels, such as lavatory and galley walls, partitions, monuments and bins. She said the company hopes to test them in the “very near future.”

    So things like the interior plastic “wall” you can touch when you’re sitting in the window seat. It sounds like a good use for this material if it is otherwise scrap, and has better characteristics than the virgin materials they’re using today for these parts.


  • I was thinking about why I stopped using Redbox and found it cited in the article:

    “With theaters shut down, productions put on hold, and consumers cooped up at home, Hollywood scrambled. Major studios threw out their release schedule and prioritized their own streaming ventures. Disney postponed the theatrical release of Mulan for months, only to eventually take it directly to Disney Plus. Warner Bros. released all of its 2021 movies on HBO Max.”

    Redbox used to be a cheap way to see a new release that I wasn’t willing to spend a movie theater ticket on, but didn’t want to wait for it to end up in a back catalog in a streaming service. The studios fixed this problem for me, and I didn’t really need Redbox anymore.







  • And just to remind people. “Rare Earth” materials aren’t actually rare. They’re common. However, they are distributed in very very low concentrations, so you have to go throw mountains worth of material to extract measurable amounts of Rare Earth materials. This is typically energy intensive and ecologically destructive, which in most of the work equals “expensive” which is why the nations of the world have been happy to shut down their own Rare Earth extractions facilities any paying China to destroy its ecology instead.

    China is free to set up its restrictions on exports. Other nations are free to restart their own extraction operations (with the costs that come with it).
