    Industrial cooling towers are usually evaporative in my experience, smaller ones are large fans moving air over a stack of slats that the return water is sprayed or piped over and the collects in well for recirculation, larger ones afaik (like what you’d see at power plants) operate the same idea. Top ups and water chemistry is all automated.

    Those systems have operation wide cooling loops that individual pieces of equipment tap into, some stuff uses it directly (see that with things like industrial furnaces) but smaller stuff or stuff that’s sensitive you’ll see heat exchangers and even then the server & PLC rooms were all air cooled, the air cons for them were all tied into the cooling water loops though.

    From a maintenance POV though, way easier to air cool, totally seen motor drive racks with failed cooling fans that have had really powerful external blowers rigged up to keep them going to the next maintenance window. Yeah, industrial POV but similar idea.



  • I bought a Brother colour laser last year (which on the outside looks identical to the monochrome one I bought 17 years ago that lives with my parents), zero issues, which pretty much has been my experience with printers on linux (also tried a ~5 y/o & 25 y/o HP LaserJet, one being the cheapest thing I’ve ever used, other being old office equipment, think I tried the Epson ecotank and photo printer my mil has as well)


  • It’s not terrible advice tbh, even just hand sketches are solid for getting ideas down, makes it easy to translate to cad. It at least helps me think things through and the like.

    Get a few pencils with different leads (some harder stuff like 2-4H and an HB) and some nice paper and you’re good, but really anything works, totally have a mockup of my garage on a whiteboard planning where I want to put stuff.

    As for cad packages, freecad, as far as I’m aware there are some architecture workbench plugins, and there’s a tech drawing workbench. Coming back to cad after a while I found it super easy to pick back up (coming from solidworks at least)






  • The ones I have have some speakers aimed at your ear to fill in that part, actually works really well. I can’t stand the ear buds you physically insert into your ears, the rubber tipped ones, these have been good to replace my on ears for activity. Plus you can hear what’s around you which is why my partner gifted me them.
