DailyDirt: More Miraculous Manmade Materials

from the urls-we-dug-up dept

There's no shortage of new man-made materials being developed, and they come in all different shapes, sizes and purposes. Sometimes it's about making something old in a new way, or giving something common an extremely uncommon property — or just producing something in previously unimaginable quantities. Here are some new developments from the world of synthetics.

After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Spider silk is harder to just "brew" because the process of fiber spinning that a spider does is done at a scale that is just insanely impractical to do with any kind of tech we currently have. Good luck with that. Maybe they can get silkworms to spit out a form of spider silk.

    Re:

    I recommend you watch the Rice University video on producing Carbon Nanofiber threads and then go on to look into their partner Teijin Aramid:

    In the video you can see the fiber spinning cylinder used.
    Created spider silk is much closer to mass production than you thought.

    > transparent version could be an ideal material for solar cells, among other things.

    If it is transparent, it is not capturing energy from light (in the frequencies for which it is transparent). Maybe they're talking about heat-capture? That is, a direct replacement for glass/plastic coverings in existing solar cells?

    And from the linked article...
    >Berglund says transparent wood panels can also be used for windows, and semitransparent facades, when the idea is to let light in but maintain privacy.

    ... sort of like bamboo paper partitions, or greased paper windows... The article doesn't say how much more cost effective this transparent wood would be over using glass. For now, I'd say it's a novelty but I'm not yet sold on its utility.

    Re:

    When they say transparent wood is ideal for solar panels, they mean as a cover. Glass is fragile and expensive, and unbreakable glass way more expensive. Transparent wood would not be fragile while still remaining cheap.

    CO2NCRETE

    I can't think of a non-problematic way to pronounce it.

    Re: CO2NCRETE

    I think it's probably best pronounced as something like "see-oh-tune-crete", only with a bit more separation between the "tu" and the "n".
