City plans to triple system of underground pipes that distribute chilled river water, reducing need for individual cooling units

I made a post on !gardening@lemmy.world about the different methods I use to automate my plant watering.

It features "solarpunk" ways to achieve that, mostly low-tech that isn't reliant on any electricity or water grid. I want to spread the solarpunk spirit on Lemmy, to safe lots of water, labour and stress.

Check it out if you're interested! :)

Industrial electrification potential much higher than commonly assumed

Some good news on this FOSS alt to discord. Moving along well but still in beta and testing of Mobile versions. Still nice that the work is pushing along and might not be a spur of the moment fad

Lovely! Now my domains are safer :D

Just discovered her.

Watching her vids brings peace to my mind.

Plus she's super cute.

The European Commission has decided to restrict EU funding, including through the European Investment Bank and European Investment Fund, for solar, wind, and energy storage projects using inverters from so-called high-risk countries, namely China, Russia, Iran, and North Korea, citing cybersecurity risks.

...

For projects outside the EU and not connected, or planned to be connected, to the EU grid, inverters from high-risk suppliers should be phased out by 15 April 2027. Technologies covered include inverters across all renewable energy applications. The rules also apply globally to companies owned or controlled by those countries.

...

According to [EU] documents, the Commission notes “Energy storage systems / Power Conversion Systems (PCS) are explicitly included,” which places EU-backed battery energy storage projects on notice, particularly those relying on integrated PCS supply from Chinese and other suppliers.

In terms of sourcing, many batteries that are supplied from Asian sources include all-in-one options that package the batteries and cells with the PCS. For those projects that are now facing bans on inverters, sourcing lists may be constrained or require changes.

Christoph Podewils, Secretary General of the European Solar Manufacturing Council (ESMC), confirmed to ESS News that the decision doesn’t have exemptions based on power class.

“It’s really a strict regulation, without many loopholes… It also concerns inverters supplied from entities under control of the high-risk countries, so for instance, a company producing, in Europe, inverters belonging to a Chinese entity.”

When you're building the solarpunk future, it's possible you might spend hours in the workshop. If you need a PPE solution for airborne contaminants - consider building your own powered air respirator (PAPRa). You can build this PAPRa for less than $200 in parts. Originally created during the pandemic when supply chain issues made it difficult to acquire these devices. Wearing a PAPRa is more comfortable and safer than wearing an N95.

Another banger from the Low Tech Magazine. This time : the trusty handcart.

This thing is fantastic. Entry information about how to work with Docker, backwards compatibility with older versions, clear details about every option. This is what every project should aspire to.

There's a good video that shows it off here.

EDIT: it seems the main dev stepped back from the project in December, and I'm unsure where the community is continuing its development, or if they are at all. So unfortunately unless someone else steps up the maintain it, it might not be developed any further. In that case, Meshtastic is still likely our best option.
