What about a pre-extruder or a set (or pultruder?) that brings it to just below the glass transition temp, but still at the original filament size? Water boils off, plastic is left!

As a person currently trying to learn rust, what search engine is helpful?

You are right the core of most optical fibers is either 8-9um for singlemode, or 62.5 or 50um for multimode. The cladding, which is also made of glass, surrounds the core and this is almost always 125um. Often there is more than one layer that makes up the cladding glass to help reduce the bend radius before you start to attenuate your signal. You need both the core and the cladding of different refractive indexes to create total internal reflection, which is how fiber optics work over long distances with low loss.

The glass (core + clad) is the only part of the fiber that is really recyclable. Everything else is plastic that is difficult to chemically remove.

There’s a lot of really bad literature out there on fiberoptics, so I don’t really blame anyone for not knowing this stuff. Here’s a pretty good article that sums up how fiberoptics work I pulled off google: https://www.ofsoptics.com/faq-guide-to-fiber-optic-cable/how-do-communications-fiber-optic-cables-work/

Some are complex, most aren’t I’d say.

Most optical fiber is 125um of glass with 250um coating. The coating and the jacketing that make up the cable (mostly non-recyclable plastic) are the real problem.

Fiber optic cables are very much not recyclable, at least with the current recycling technologies.

If you think about it, if looking 10 hours younger was constant, you basically created eternal youth. I’d say that’s pretty great.

I think part of the problem is that it is very dependent on what the invention is. Yeah, for some nicknack, that’s a reasonable time frame. But for some kind of massive project, where distribution, complicated supply chains, and many people are involved, this time gets eaten up quick. Imagine you have an invention, thats totally cool, but 10 years of your time is taken up trying to make it at scale to make it profitable? Meanwhile, someone else can establish all those things without breaking patent, and go to market as your patent closes. You aren’t wrong, its just not always so simple.

Thanks, I had only checked the store. Didnt realize it was an early access thing

It doesnt appear to be released for Android yet. Why you gotta get my hopes up…

I have many of these in my back yard every year. They are closely related to blueberries! I wouldnt eat one but apparently you can for a good time!
