  • 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.




  • 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).








  • Cable companies have seen the writing one the wall with Cable TV for quite awhile. They had the perfect product to pivot to with broadband. Had they offered a great product with great customer service, they’d have had the market forever especially how much consumers felt burned by telecoms abusing their market dominance with with early broadband.

    Instead, cable companies doubled down on the lock-in and bundle model with deceptive pricing and horrible customer service ceding ground to wireless providers and even the same telecoms that were hated before.

    Our household cut the cord on cableTV/satellite about 14 years ago, but kept cable modem service since then. Now that the local telecom has laid fiber at 500Mb/s for $49/month we dropped any relationship with the cable company. Two months before the fiber came in, cable suddenly dropped the price of our 100Mb/s service and increased the speed to $300Mb/s. At $80/month it was still better for us to ditch the cable company and go with the telecom fiber connection.








  • Hmm, you’re making a good point and introducing two new not-yet-considered elements.

    1. Wolverine is only 5’3" (160cm) tall. Was he originally taller, but had a body destroying even, that only 80% of him was able to grow back rendering him shorter than he was before.

    2. Wolverine is Canadian. So neither the USA or Oz money rules apply, but instead Canadian rules. What those are, I do not now.
