Finally! I built & tested an open-source concept model air purifier that should be good for schools. Lots of air (CADR > 420 CFM), quiet (<45 dBA), uses <9 W, and ‘cause it’s wall-mounted & down-blowing, it moves air in the right direction & takes up no floor space. Always check my ALTs🧵⬇️

@nukit.bsky.social has posted another outstanding tutorial on 222nm UVC. It's on that other site x.com/NukitToBeSur.... This time she explains radiant power output vs. irradiance at nadir and polar plots. A must-read if you're contemplating UVC and you're at least slightly technical.

@nukit.bsky.social has posted an outstanding modeling effort on her blog at www.nukit222.com/blogs/info/f.... and on that other site x.com/NukitToBeSur.... She not only shows how she did the modeling but also the conclusions she reached and how to think about Far-UVC/air purifier combinations.

@mark-ungrin.bsky.social I'd put this in a chat, but u don't accept them. I really like what you post and your positions but I'm going to have to mute (not unfollow) you because I'm overwhelmed by your reposts. Going thru my overnight feed I got 33 Sbucks to 1 other. None of the 33 were new to me.🥴

Here's a preview of an open-source concept model for an air purifier that I think would be good for schools. It’s wall-mounted & down-blowing, but requires ceilings over 9'. 426 CFM CADR @12V, but I'm still checking the noise before publishing details. Maybe a couple weeks. See ALT for info.

Has anybody called it Elongate yet? If not, I call dibs.

IPC in NB in 2025: okay so the focus for this year is handwashing. We are really emphasizing handwashing. The board wants the quarterly reports of the handwashing. Handwashing, handwashing, handwashing.
NBers: if you want healthcare to ALSO acknowledge airborne be LOUD! Write the RHA boards & MOH!

@lazaruslong13.bsky.social I love your posts on the other place. You're one of the few people who reposts a lot that I follow, because you're a good curator of technical posts. But i hate going there to see your posts. If you'd post everything both places I'd follow you here & mute you there. 😀

Thanks so much for posting this! I was the engineer for the payload power supplies on all (7, I think) Lunar Orbiters. It was really thrilling when the pictures came back.
Loved this thread by @spacemarschall.bsky.social showing the location of the Apollo 11 lunar module. Wanted to find the same spot in Lunar Orbiter photographs, for a before/after. Here's the same location as viewed from Lunar Orbiter V on August 12, 1967.
