Lithium-free sodium batteries exit the lab and enter US production (newatlas.com)
It’s so rare to actually see a new battery tech exit the lab and enter production. Always seems like there’s 10,000 new up and coming breakthroughs in battery technology, but none ever leave the workbench....
Generate shadows without trees: vegetable awnings, a new way to generate shadows in the city. (www.singulargreen.com)
I found these kind of cool as an idea, as they can be added rather easily to existing cities and provide some greenery without taking up space, while providing shade:...

I was watchin the last episode of ‘‘earthsounds’’ (docuseries that you can find on torrent) and they said to have used one of this with a microphone mounted under it to record better sounds from whales (because they travel a looooooot and not always on the same routes)....
Why Flushing Isn't For Everyone - YouTube (youtube.com)
💩 tech! On a serious note, this was in my random recommends and I clicked it and now I know about something I had no idea even existed. If this technology can come to fruition, it’ll be great for the world.
New PCB design is repeatably recyclable — vitrimer PCBs could save millions of tons in eWaste, say UW researchers (www.tomshardware.com)
Keurig's new K-Rounds coffee pods are plastic-free and could finally make single-serve coffee-making sustainable (www.techradar.com)
This is quite exciting in that it removes plastic waste. I see no reason why different companies can’t make different shape ones to maintain their lock-in. I expect a knock-off market to pop-up, but that exists with plastic pods too. It’s a step in the right direction at least.

solar concrete kiln design questions (slrpnk.net)
This might be a bit of a reach but I’m wondering if anyone here knows enough about concrete production to help me plan the layout of my next photobash. I’d like to do a scene of a solar-thermal concrete factory – there are several supposedly in the works, like Synhelion’s new partnership with Cemex, funded by the US DoE,...
