  • The problem with a lot of the architectural solutions taken from the past is that they rely on an open building envelope. Ventilation is great when it’s enough, but the moment you have to close off the building envelope to use mechanical air conditioning, those architectural features dont help. Swamp cooling has similar challenges.

    Shading, however, is a really important feature that we are largely missing. Lots of eco-friendly buildings are designed with large overhangs over south/west facing windows to block sunlight during the summer and let it in during the winter. I think it would be neat to have a building that is designed to be slightly more “active” than that. E.g., maybe every equinox you deploy/stow a rigid awning structure, so you get even more light in winter and less in summer.


  • It’s a little strange because I dont actually really know who the audience of the book is supposed to be. The main text seems aimed at people who would purchase the stuff, but the appendices seem aimed at people who would be producers. The content seems like something that a library should have, but it’s printed like a phone book with paper that probably wouldnt hold up to library usage.

    I could almost see it as a “coffee table book” in a store that sells locally made, quality stuff, but that can’t be a very big market.



  • That’s a little out of scope: the catalog is all stuff you’d wear for the most part. There is a section for companies that make costumes, though, ranging from stuff you’d wear to a ren fair to serious re-enactor clothing.

    There’s also a decent amount of leatherworkers who do sheaths.

    I wish I had an equivalent resource for tools, because there’s still a good amount of small businesses making tools.



  • Having battery storage is the most expensive part of any off-grid system. Without it, you obviously dont need batteries, but you can also get rid of all the battery management stuff, charge controlling, inverters, etc.

    Direct attic fan sounds great because you need it the most when it’s the most sunny.

    It would be cool to do a direct solar powered hydroponics or pond project, where you just pump all the water to a reservoir when you have sun, and let it drain back 24 hours a day.



  • Balcony solar that is grid tied is probably not something you want to DIY. The amount of power you can generate probably wouldnt be worth the hoops you’d need to jump through. That’s not including using the smart inverters that plug in (cause that’s not really “diy”).

    Off grid balcony solar isnt super hard. If you have an all-in-one charge controller/battery/inverter (jackery, goal zero, and a million others), you just plug the panels right into it, and you can pull power out the other side with no trouble. That’s also debatably “diy”. Getting a little more advanced than that still isnt too hard.

    Personally, I have a goalzero power station and 300W of panels. I wish I had done a little more research before buying the goalzero, cause I probably would have gone a different route (LFP battery, not NMC) because I care way more about charge cycles than energy density.







  • What many backpackers do for a quasi-BIFL approach is to just buy a non, waterproof bag that’s durable, and use a garbage bag on the inside (typically bags designed for trash compactor or nylofume which are much more durable than normal bags).

    The problem is no coatings last forever, so you might as well have your waterproof layer be a replaceable wear item.

    If you do want something that doesnt require an extra bag, avoid anything that has a coating on the outside, because that is inherently sensitive to abrasion. This especially includes DWR, which mainly serves to shed water and prevent water from getting into the fibers, not preventing water from getting inside.

    Also, avoid gore tex or similar. Those are good for on your body, because you are generating heat (and sweat) so it needs to be breathable, but a bag does not need to be.

    I prefer coatings to be on the interior of the fabric for durability. Some people like it on the outside so water gets shed instead of getting the fabric wet (even though whatever is on the inside will be dry). Coatings like polyurethane are actually waterproof, though they will break down over time if they are kept hot and humid, so just make sure you take care of your gear.

    Alternatively, a waxed cotton canvas may be the best bet for you since it can be retreated as necessary.


  • I’ve never made paneer, but I have made a lot of ricotta (well, this type of ricotta, there’s also leftover whey ricotta, which I haven’t made). I had no clue paneer was basically just pressed ricotta.

    Do you ever salt it, or is that just not common with paneer?

    My trouble is always ending up with too much leftover whey. Yeah, you can use it in bread, but unless you are baking like 4 kg of bread, you won’t use it all. I’ve used it in soup, too.




  • I am still using a Nook (Barnes and Noble’s brand) ereader from 2009. It was in storage in a damp basement for a year, and the fake leather case it was in literally disintegrated around it, but it was fine. The battery turned spicy pillow, so I replaced it for a few bucks, but other than that, it’s still working great. I haven’t connected it to wifi in like 10 years, so I have no clue how well transferring books from a library works. It has a micro SD card slot that makes it capable of holding a huge amount of books, so I just drag/drop a hundred books on every few years by plugging it into my computer. The only complaint is no backlight.




  • Everyone likes to claim that eggshells are some kind of a amazing fertilizer, but they aren’t. They are calcium carbonate, which is not really water soluble (in other words, not available to plants). You can improve solubility by baking and then pulverizing them to a powder. They are basic, though, so it’s possible to rise the pH too much for some plants. I wouldn’t just do it willy-nilly.

    It would be awesome if balcony gardeners could just scrounge all the fertilizer their plants need, but it’s not easy. If you are on a budget, you can just buy a canister of miracle grow that will last indefinitely for $12.
