I have never been able to decide if his videos are boring or interesting, he seems like he wants everything but the camera.

His 'Bulletproof Wood' video was very frustrating because he kept getting the solution to only be absorbed by the surface of the wood, had a great cross-section cut that showed it clearly, and then never did anything to work on getting the entire wood to absorb it. Instead inventing superbly elaborate solutions to other parts of his procedure.

Shoot the wood full of holes to create channels for the hardener.

Hear me out: what if you planted trees in hardener , that way the wood would be filled and hardened when it gets harvested.

The best thing is this is a solved problem, you vacuum infuse it, which is how you create stabilized wood using heat activating epoxy.

There’s a better way. You use a radiation-activated epoxy that can soak in over a long period, then put the wood in a nuclear reactor.

It's not a thermoplastic, it's a radiation initiated cross linking resin. There's cross linking resins you can trigger polymerization without radiation or even cross linking resins that aren't classically reacting that you can impregnate wood with which is what started the whole conversation but it's not going to have the same properties as Lockwood. Properties including how easy is it to impregnate the wood or what the final product behaves like. Fun fact your toilet paper is held together with a cross linking resin that doesn't exactly reactively bond which let's it dissolve in water over 5-15 minutes so you can wipe your rear end and stop up pee but it doesn't clog your pipes and septic system. Paper chemistry in general sees all the varieties of cross linking between what you can do with cellulose fibers and what you can do with additives and resins. E. Tldr the resin in lockwood chemically bonds with itself, and also the cellulose-lignin structure which is a monumental idea compared to most other wood impregnations you can do. zedprime has a new favorite as of 15:09 on Mar 19, 2024 |

Have there actually been serious rockets that used fluorine as their oxidizer? My impression was that even "just" elemental fluorine is so temperamental that nobody wants to use it.

Someone did build the insane tripropellant engine, but only for an on-the-ground test series; I don't think anyone actually got around to flying it.

Thread is a flat circle. Behold: Flox Methane Kazinsal posted:Winchell Chung's "Atomic Rockets" site updated recently, with one of the additions being a section on a 1966 study by Rockwell on a capsule-style Mars lander that ran on a delicate balance of liquid almost-FOOF. zedprime posted:Quoting original post from 7(!) years ago for posterity. The links have moved around a bit so the FLOX explanation for the Martian Excursion Module is here now http://www.projectrho.com/public_html/rocket/excursion.php#rockwellmem and the IMIS mission profile is better accessed from http://www.projectrho.com/public_html/rocket/realdesigns.php#id--Boeing_IMIS. And yeah, most fluorine oxidizer rockets never left test sizes because getting enough fluorine in one place is a big engineering challenge.

Yeah, I knew they'd been tested, the potential for high specific impulse is too much for rocket scientists to resist. But for actually delivering payloads to orbit (or to targets on/above Earth, anyway), I wasn't aware of any examples.

My layman's understanding is that about 99 times out of 100 fluorine oxidizers don't offer enough additional performance to outweigh their downsides in almost every other respect like toxicity, difficulty in handling, volatility...

Yeah luckily it turns out "just throw more kerosene+LOX at the problem" is a good-enough answer for most things that need to be shoved into space, that even if it doesn't have the best efficiency it's relatively cheap and simple

Speaking of the tripropellant engine, there's an hour-long YouTube video by someone who isn't an irritating bazinga about it. https://www.youtube.com/watch?v=KX-0Xw6kkrc Quick teaser: Asbestos insulation is one of the least dangerous substances involved in the apparatus.
