@chrisnelder@mastodon.energyIn 2022 I drove across Canada from Ottawa to northern BC. I remember driving for three full days around the top of Lake Superior with a wall of mostly dead trees on either side of the road the whole way, thinking, man when Ontario burns, there's going to be no stopping it. And here we are.

@cdarwin@c.imAmbassador Bridget Brink here.
Putin just unleashed a nuclear-capable ballistic missile in the heart of Ukraine’s capital, Kyiv.
This was part of one of the biggest attacks on the capital since the start of Russia’s war in 2022.
And the Russians say this is just the “beginning” of a new wave of strikes on “decision-making centers” in Kyiv.
And what has Trump or Vance or even Rubio said?
-- Nothing.
Instead, last week they extended the waiver of sanction…
@waidler@bayerwald.socialTrump bricht bei „Meet the Press" (NBC) das Interview ab, als Moderatorin Kristen Welker ihn nach Belegen für seine „rigged elections"-Behauptung fragt. Seine Antwort: „Ich muss nur hinschauen." Auf ihren Einwand, das sei kein Beweis, beschimpft er NBC, ABC, CBS & CNN als „krumme Sender" und geht. Belege? Wie immer: keine. NBC stufte danach mehrere Aussagen als falsch ein. Schon 2022 lief ein NPR-Interview genauso.

@bibbleco@infosec.exchangeJust did very approximate calculations; with 10g of lithium per drone*, and assuming the Russian and Ukrainian drone efforts consume 5m units a year**, that'd be ~50 tons of lithium deposited into the environment per year, mostly within, let's say, 50km of the grey zone***. It's only about $20,000 / ton****, which means $1m of metal*****.
So to answer my own silly question: no, it won't be economically viable to scalp the top few inches of topsoil and extract the lithium from it.
* Roughly right for quadcopters / small FPV; larger and longer range ones will have more, so this is a bottom bound. (OTOH longer range UAVs will tend to use ICE kerosene rather than batteries
** Changing all the time as both sides try expanding production as fast as they can manage. Ua are scaling much faster at time of writing
*** Handwaving. Contact zone's hardly moved since early 2023; OTOH Ua are pushing range limits on small battery-powered form factor, saw a 60km claim for the Logistics Lockdown operation the other day
**** There was a big spike to the $70-8000 range in 2022; median price is closer to $10k than $20k
***** (IDK the chemistry but presumably it's in an exciting range of different compounds, depending on how many bits the battery was blown into, how hot / pressured the blast wave was a few tens of mm from the boom, what other stuff was in the vicinity that the lithium would combine with, etc etc.

Translation: NDAA-compliant gear is still not as good, much less as cheap, as pre-2022 gear from these companies. If you want people to buy US gear, at least make it work as well! BTW, ALL cameras should be on an isolated network. https://ground.news/article/the-us-has-upgraded-restrictions-on-chinese-companies-banning-imports-of-products-from-five-companies-including-huawei
