  • chinampas

    Hi, I’ve been reading up on chinampas to try to get the details right and I was hoping to borrow some of your tree knowledge. Most sources mention a willow (Ahuejote (Salix bonplandiana)) and a cypress (Taxodium mucronatum) as the trees they used to reinforce/replace the underwater fences for soil retention. I’m sort of doing this picture as if its in New Orleans (for some of the buildings and other details anyways) and I think that’s outside these specific trees current ranges. I was wondering: can I swap in any other cypress or willow since there are some native to Louisiana or would some cause problems?

    Here’s what I’ve got so far:

    I’m probably not showing enough alternating layers of plant matter and mud, but I’m hoping it gets the point across. I’ve tried to find good sources, so far these diagrams are my favorites:

    Some seem to show floating islands or like, a floating top layer with water underneath, inside the reed wall, which seems weird and inaccurate from what I’ve read. At this point, I mostly just want to get all the trees added, make sure they’re realistic, and find some accurate roots to include to show how they reinforce the earthworks. From what I’ve read it sounds like willow and cypress just kind of put roots everywhere (I’m used to being able to find clearer diagrams for trees like pines and oaks, but have struggled to find good drawings for these. Also might add cypress knees in the waterways where they’re really well established, we’ll see. Then I’ll start cleaning up the image and getting everything to match aesthetically.







  • This is really cool! I really appreciate the history and the way they changed things around them, along with changes in the way they’re perceived. I also think the distinction between the sort of black box device and the focal thing, directly used and serviced by people, is worth considering.

    I’m optimistic that solarpunk as a genre might be able to help with the aesthetic appreciation of modern windmills at least. They show up frequently in solarpunk art (though almost more often in the form of altaeros temporary windmill blimps):

    I even included one in a scene of a ship at sea:

    Its cool to think that the aesthetics of an optimistic genre/movement could help sway the culture in a way that helps support windmills. I also really like the author’s suggestions for education possibilities, helping people engage with them, feel a sense of ownership or pride in them, if they are so hard to ignore.


  • So this is a question that’s been in the back of my mind for awhile while seeing celebrations of dams being removed, no worries if you don’t want to be the one to answer it.

    I think I understand the extent of the damage caused by the implementation of dams, but I guess my impression had been that that damage was done, and there wasn’t much of a timeline on fixing it. Like, after eighty years or so, are there fish still trying to get past it?

    At the same time, we’re struggling (failing?) globally to get away from fossil fuels quickly enough to avoid the worst of climate collapse. It seems like hydro is one of the more reliable green power sources, and is compatible with old grid infrastructure that counts on fairly consistent power so there’s less than has to be overhauled in order to just keep using hydro for awhile longer.

    So at first glance, it seems like new solar and wind etc production would be better prioritized in replacing oil, coal, natural gas. Prioritizing replacing hydro feels like letting the perfect be the enemy of the good.

    I haven’t seen that discussion anywhere, so I genuinely expect I’m wrong about that, but I’m wondering why.




  • That’s a good list, thank you! I have a couple questions you might be able to answer:

    Could you elaborate on the relays? I don’t know anything about them yet (in their intended use or alternatives). Though I am reading up on them.

    I know there’s a some benefit in running 12v appliances (intended for campers) with solar panel setups because you don’t have to convert from DC to AC then back to DC at the appliance. Would that work for just using a car’s AC unit to cool a room, or are they built too specific to a car or not efficient enough to justify the work?

    Thank you!!







  • Ecotopia is a fun one because it hits all the notes but predates the genre.

    Murder in the Tool Library is a favorite of mine because the setting is awesome and aspirational while feeling real and human, and because the murder mystery plot is a change from the usual ecofiction.

    The solarpunk TTRPG Fully Automated! is free (libre and gratis) and has several sections devoted to its setting and worldbuilding that helped me understand a bunch of solarpunk concepts by seeing them in practice and to start thinking much bigger with my own fiction. It also has some good advice on creating engaging plots in an aspirational solarpunk setting where a lot of the usual problems have been solved.


  • That’s interesting, even going with modern tech, it’s a neat answer to preserving darkness. Military-grade passive night vision with the analogue tubes are ridiculously expensive but you wouldn’t need them just for walking around - simple infrared spotlight goggles are way cheaper, and probably lighter, especially if you remove extra binocular features. They could also be assisted by infrared streetlights if those wouldn’t mess up other animals. Downsides: I don’t think walking while wearing them would be fun, your depth perception and field of view takes a hit with most designs, and slow update of the screen can be disorienting. They’re also more complicated to make than flashlights.


  • That’s an interesting idea - instead of carrying a flashlight you might carry an RFID transponder. They’d need to not be linked to any personal records (such as purchase) to protect anonymity and prevent tracking. And a personal flashlight might still be useful.

    I’m not sure I love the idea of lights flicking on, identifying where I am to someone waiting in the dark. Maybe it would turn on lights for a block length on the street or something? I’m also wondering if the reduced on-off cycling would wear out lights faster and, if so, how replacing them more often stacks up to more energy spent running them all the time.

    Still it’s an interesting compromise position on the light pollution situation.
