Wow I haven't read a good chunk of this list, and I thought I was a sci-fi book afficionado. Thanks for adding to my summer reading list! Might start with either Parable of the Sower or Never Let Me Go.
I tried that out and posted the picture in another comment in this thread (https://lemmy.world/comment/10346090). I think it's better but I have some more to learn. Your photo is brilliant!
Thanks, that's exactly how I took the photo. It was approaching sunset so I think the colors are a little yellow because of that and just how brown the river is. I adjusted the colors like the other comment suggested and I think it looks better:
Thanks, I've been practicing getting the focus sharp. It's a tough battle between my phone's autofocus vs manual bino adjustments and keeping the phone+bino stable. I still feel I have more work to do on that too.
One more thing. Running hydrogen, even in blends of 30% hydrogen/70% natural gas, creates a large amount of extra NOx production. NOx, of course, is a pretty nasty pollutant. We need to redesign our current natural gas burners to help control NOx at high hydrogen blends.
Also, I think we need to be moving towards 100% hydrogen if we want to use combustion as a green replacement for natural gas. However, I don't think many of the appliances that currently use natural gas could safely use 100% hydrogen because of the properties of hydrogen gas. Primarily, I think the flame speed of hydrogen would require us to redesign the various combustors that use natural gas currently so that we don't have flashbacks. Additionally, the hotter burning of hydrogen might cause material failure issues in our current natural gas burners. The research I've done is shown that we could probably get away with 30 to 40% hydrogen, maybe dependent on the exact burner. I don't think moving to 100% hydrogen is feasible without a massive replacement of all of our gas burning appliances.
The missing middle. The last city I lived in had a bunch of houses in the 1200sqft 2br/1ba range but they were built before 1950 and are now in the "historic" part of town that is zoned to prevent redevelopment. It's also the closest to the city center where many jobs are located and events like festivals take place. So it's a very desirable place to live and houses here sell for $1M+.
The next ring out from the historic district was built between the 50s and early 2000s and is largely 2000+sqft homes on larger plots of land. Large plots of land are desirable so those go for $800k+.
After the 2008 financial crisis we started building our third ring of housing with humongous "luxury" houses with 6+br. They're on tiny plots of land with maybe 6ft separating the houses, but since they have large sqft, granite countertops, and faux marble tiles in the bathroom they go for $700k+.
Oh yeah and housing has been underbuilt since the 1970s so the vacancy rate is under 1%, and it's a smaller city (~200,000 people) so the job opportunities aren't plentiful and the best paying. I have no idea how so many of these houses are being paid for. I bet a lot of people that have bought since 2010 are house poor. Or a lot of them are cruising on super low interest rates.
I've been using SALOME to create parametric 3D geometry. My use case is to parameterize my geometry features and export to STL files that I use with OpenFOAM. SALOME is integrated with a couple of grid generators, and I really like it's 2D/triangulation/STL integration with netgen. You can specify faces for refinement to a desired mesh size, so for example around complex features you can create a fine STL mesh and on simple shapes you can have a really coarse mesh.
I've found the 3D modeling to be pretty straightforward, and SALOME usually does a pretty good job if you have to go back and modify previous features (something I've struggled with in FreeCAD).
I've also used FreeCAD for mesh generation, and it works ok but I've found the triangulation leaves a lot to be desired for splitting up the mesh as needed for OpenFOAM boundaries.
If you're making STL files for 3D printing and you want a parametric CAD modeler for engineering parts, give it a try. If you want complex faces with artistic style, I would suggest Blender.
Recently I used SALOME for doing CAD. The Shaper work bench has parametric modeling with the sketches that you extrude or cut from. I found it powerful and easy enough to use that I replaced my freecad workflow with it. The big thing that sold me over freecad was the simplicity of creating more complex triangulations for stl export, and easily grouping faces for export into different files.
I haven't tried any complex surface creation, I wouldn't be surprised if it falls short in that regard. I guess feature wise it probably doesn't have everything freecad or fusion 360 has, but I found it works great for my needs. Great for 3d printing and geometry creation for CFD simulations.
That honeycomb body is sick looking! Love the color gradient
This probably isn't the story you're thinking of, but "There will come soft rains" by Bradbury has similar themes https://en.m.wikipedia.org/wiki/There_Will_Come_Soft_Rains_(short_story)
Maybe their diet would shift but a lot of animals eat ticks. Frogs and toads, many smaller birds like warblers and probably house sparrows and robins, chickens love them, and of course opposums and mice.
Similar for mosquitos. I see the house sparrows around here catching mosquitos all the time. I'm pretty sure dragon flies feed heavily on them too.
