I know this is a Buy European community, but when it comes to batteries, aliexpress is still your best bet. You can build your own or buy a pack that is ready to plug and play

Is nuclear really cheaper than renewables + batteries nowadays? I wonder if there are recent studies looking into it

Quick search points to this:

Levelized Cost of Electricity: which is a measure of the total cost of building and operating a power plant over its lifetime and expressed in dollars per megawatt-hour. [...] LCOE serves as a comprehensive metric that consolidates all direct cost components of a specific power generation technology. This includes capital expenditures, financing, fuel costs, operations and maintenance, and any expenses related to carbon pricing. However, LCOE does not account for network integration or other indirect costs

LCOE for advanced nuclear power was estimated at $110/MWh in 2023 and forecasted to remain the same up to 2050, while solar PV estimated to be $55/MWh in 2023 and expected to decline to $25/MWh in 2050. Onshore wind was $40/MWh in 2023 and expected to decline to $35/MWh in 2050 making renewables significantly cheaper in many cases

[...] Global weighted average levelized cost of electricity for newly commissioned utility-scale solar photovoltaic, onshore wind, offshore wind, and hydropower projects experienced a downward trend. The most notable drop occurred in utility-scale solar PV, which saw a 12% decrease from 2022 [in LCOE costs][...]

In contrast, nuclear power continues to face cost overruns and long construction timelines [...]

[Caveat: Below numbers are most likely not using LCOE]:

[...] In 2025, developers added 87 gigawatts of combined solar and storage, delivering power at an average of $57/MWh

By contrast, benchmark cost of a typical fixed axis solar farm increased 6% compared to 2025, hitting $39/MWh, while onshore wind reached $40/MWh and offshore wind climbed to $100/MWh globally [...]

If we aren't there yet, I still think we might see renewables + batteries as cheaper options in the short term.

I'd really like to see an LCOE analysis including batteries. If we naively assume LCOE costs for PV+batteries is the same as PV, we might already be there

 

This consultation is on the future of the Woodside Viaduct, a crumbling 1960s elevated motorway that cuts off North and North West Glasgow from the city centre. Temporary propping works that were meant to take 2 years and cost £35m will now take at least 6 years and £150m.

Transport Scotland now want our opinion on three options: Repair the viaduct for up to £200m extra, replace it for up to £500m extra, or remove it for under £125m.

For comparison Strathclyde Partnership for Transport say it would cost an initial £300m to create a world-class bus service as good as any in Europe for the entire region.

Transport Scotland's consultation document claims that removing the motorway causes the most pollution, even though the exact opposite happened when other cities removed urban motorways.

Let us know how it goes. I love seen how these cases unfolds in the fediverse

As some people mentioned, it is a good idea to ID them first, and depending on the species, if they are parasitic, they can kill the tree or leave it weak enough to die from something else

Some species, even if you cut their visible stems, but leave the host trunk intact without treatment, they can regrow from embedded haustoria (specialized roots) that penetrate deep into the host’s vascular system, allowing them to regenerate from internal tissues.

That's the direct result of car lobbying, it has changed the perception of a whole generation on how we should build cities

 

Center 795 was stood up in late 2022, its mandate was framed around assisting the Russian war effort in Ukraine through battlefield intelligence, special operations, and sabotage behind enemy lines

[...]

Alimov spoke Russian. Durovic spoke Serbian. Neither commanded the other's native tongue at the level sufficient for operational communication. Their solution was straightforward and, as it turned out, catastrophic: they used Google Translate, converting Durovic's Serbian field reports into Russian for his handler, and Alimov's Russian instructions back into Serbian for his agent.

The messages themselves were transmitted through encrypted applications that the men believed to be secure. But Google operates through servers in the United States, which fall squarely within the reach of an FBI surveillance warrant. Armed with a court order, investigators were able to access the logs of these translations directly from the service provider, reading the clear-text content of the entire operational communications thread in real time, even as Alimov and Durovic believed themselves protected by end-to-end encryption.

The surveillance logs, portions of which have been quoted in a newly unsealed U.S. grand jury indictment, read at times like an absurdist document: two operatives of Russia's most secretive assassination unit conducting a murder-for-hire plot through a consumer translation tool, their every instruction and status report preserved in legible, timestamped entries on an American company's servers. It was, as a source close to the investigation later noted, even better than a wiretap because it arrived transcribed.

Sorry, I thought it fit the theme quite clearly as it shows how a car centric infrastructure hurts us all, including animals. That huge parking lot could have been housing, or a park, or perhaps a big ass tub for them to swim in. (ps: I'm not saying they should be locked up in the first place, as the sea is right over there where they could roam freely though)

I was sent this map without a source but I thought it was impressive nonetheless. It shows the SeaWorld parking lot in yellow. The green dot is where Orcas spend their lives.

By holding a bag below them when they pee or pipetted from pooled urine on leaf litter

Full quote:

Urine from individually identified chimpanzees was collected opportunistically and non-invasively using a pipette from fresh and dry leaf litter. Chimpanzees predictably urinate just prior to leaving a fruit crop and can often be seen preparing to do so by climbing to a lower branch of a tree. Urination on the ground is often accompanied by defaecation, and in these cases, urine was pipetted from pools in the leaf litter opposite the faeces. Samples were only collected on dry days, since rainwater on understory leaves cannot be visually differentiated from urine. Urine may also be collected directly from underneath urinating chimpanzees by holding out a clean disposable plastic bag placed over the end of a forked branch; urine samples collected from leaf litter were previously shown not to significantly affect measured hormone levels relative to samples collected using a plastic bag

They should make rain gardens in front of fire hydrants instead of leaving the space open for parking

 

This is the question posed on CityNerd video titled "Walkable Cities But They Keep Getting More Affordable"

If you ditched your car, could you afford to leave the suburbs for a great urban neighborhood?

Ray Delahanty answers the question in the 26 biggest US cities.

The analysis assumes the all-in cost of owning and operating a car is $1,000 per month, including purchase, insurance, fuel, and maintenance.

In the city, transportation costs might total about $250 per month for transit passes, biking, ride-hailing, and other small expenses.

This results in an effective $750 per month increase in the housing budget for city center residents who do not own a car.

The results of the video are quite interesting, as you can get more m² in walkable areas in most cities

Dallas has obtained unique drawings showing the scale of the modernization of Plant No. 9 in Yekaterinburg.

This plant is a key manufacturer of artillery barrels for the Koalitsiya and Msta self-propelled howitzers, tank guns for the T-90 and T-14 Armata, as well as for the modernized T-62 and T-72 tanks.

Over the past ten years, Russia has been actively purchasing German, Italian, and Taiwanese machine tools. Even now, despite sanctions, the plant plans to install 22 units of foreign equipment. How did they get there?

The results of the joint investigation with @Tatarigami_UA are available on this link.

 

Transcription from 256 Cyber Assault Division:

You’ve probably seen this story making the rounds online: russian soldiers are trying to activate their Starlink terminals by finding Ukrainian citizens willing, for 30 shekels, to register them in their own name.

No surprise there: the enemy’s abrupt switch from reliable “capitalist” connectivity to domestic low-tech workarounds has seriously degraded their communications – disrupting coordination and putting a dent in assaults and drone activity across the frontlines.

Knowing how desperately russians will hunt for any way to bring Elon’s terminal back online –and the risks resumed comms creates for the Ukrainian defenders – we, together with InformNapalm and MILITANT, decided to help. We did so by creating a network of channels and bots that appeared to offer activation services for a fee.

In one week, we received:

  • 2,420 submissions with enemy Starlink details and precise geolocations;
  • 31 messages from would-be collaborators eager to act as registered holder for activation;
  • $6,000 in “donations” from russian troops who were frantically looking for a fix to their comms problem.

Bottom line:

  • Information on enemy terminals was passed to Serhiy Sternenko so they can be permanently neutralized;
  • Data on would-be collaborators is already being processed by the competent Ukrainian authorities;
  • The shekels we “farmed” off the enemy will cover several urgent fundraisers for Ukraine’s Defense Forces.

Monsanto, and its German owner Bayer, maintain that glyphosate does not pose a health risk, and government officials say that residues of glyphosate and other pesticides found in food products are almost always so low that they are not considered harmful.

But international scientists affiliated with the World Health Organization have classified glyphosate as probably carcinogenic to humans, and recent studies out of Europe have found glyphosate herbicides pose not just cancer, but other health risks.
