  • Chicago recently built a bunch of solar to directly power all city government buildings, so researching that and politely taking your town or city into doing that plus battery storage might be worth a try just from a cost point of view.

    Similar initiatives have worked at a municipal level for things like fleet electrification and heat pumps, though this is all stuff that was a much easier sell if you got the program moving last year.

    Other people mentioned congress, but while important to keep the pressure up for 2026 in the near term focus especially on talking with your state legislature and especially city council members.

    Look up YIMBYism, show up to your public meetings, be polite and ideally bring some friends, remember that even in large cities major projects are routinely rewritten or expanded at the behest of the one or two people who showed up to every meeting with a clear, this is what I want out of the project and this is the easy way to do it.

    Join your local left leaning orgs like DSA and mutual aid groups, even local progressive dem orgs. Even if they have some shit takes, which they inevitably will, remember that in the end doing good in the next few weeks and months is worth infinitely more than everyone agreeing on theory for what happens in the hypothetical world beyond late stage capitalism or how a few dozen people from Pittsburg are going to bring about an end to imperialism.

    Talk about the importance of growning your towns bike lanes into a cohesive and safe network people would trust their twelve year old kid to get from home to school to visiting you at your workplace on, strike up conversations and network with the people who also raise good questions and requests at public meetings, and most importantly listen to what the people that have been working on advocating for these these things for decades, they have more experience, political capital in town, and may be convinced to help with your thing like municipal electrification.

  • This has been a long time coming, and most of the decent ones chose to resign rather than split the party. I remember for instance years ago when the far right really started winning elections in Idaho, a lot of the lifelong conservatives chose to resign in quiet protest rather than fight them or try and work with them.

    It’s basicly the same thing you’re seeing in the federal government now, a lot of the people would rather resign than deal with him, and as such he gets to fill the roles with his loyalists without a fight.

  • It’s effects tend to very based on plant and local conditions, but typically the point of agrivoltaics is to shade plants in hot, dry climates around midday to improve yield. At low angles sunlight goes around the panels, but at peak sun they are shaded.

  • This way an ‘innovative’ and ‘disruptive’ approach that can be the basis of a startup that can be sold to a bigger company or IPO for a bunch of money, and as a bonus draw clean energy funding away from tried and tested solutions into inefficient gimmicks that in turn keep the gas plants running that much longer.

  • So the impact of Chinese climate policy is also vastly overestimated because the Chinese are a small minority of earths people?

  • Kinda sorta? The carbon still goes into the atmosphere and there’s such demand for used cooking oil to run vehicles that there have been cases of new cooking oil being mixed into used because it was more valuable for vehicles than cooking, but if it was definitely going to get burned in a waste incinerator than better than nothing.

    Climate wise, electrification (either for bikes, cars, buses, or trains) remains the only option and is something everyone is going to have to do eventually, but economic wise the higher upfront costs limits access.

  • This is a funny accusation in light of the amarican situation where our leader openly owns multiple businesses in Russia and other foreign nations, to say nothing of selling pardons or any of the other blatant corruption.

  • Chernobyl and the Exxon Valdez are pretty comparable in scale and scope the environment, though Chernobyl certainly had a lot more human casualties.

    That being said I’m not sure public opinion actually has had that much of an impact. If they wanted to, the same companies who keep building new oil pipelines no matter how many protesters need to be beaten into submission by cops could absolutely have pushed through adding on some more reactors to existing plants. The problem is that while profitable, nuclear is not as profitable as heavily government subsidized oil and gas much less solar, and so no one but some of the public really wants to put a lot of money into it.

  • Nuclear was the correct answer, when climate change entered the scientific community in the 50s, it was the correct answer when it allowed France to nearly hit net zero for energy in the 70s, and it was the correct answer when the UN agreed we were all going to die unless we stopped burning all fossil fuels in the 90s.

    The problem is that ever since the 2010s it’s been outpaced by improvements in wind and especially solar. Not coincidentally this is about the time that oil and gas companies stoped campaigning against Nuclear and suddenly started insisting that it was the only possible alternative.

    It makes sense to keep what we have running and do some refurbishments, but in a world where the primary limit on the amount of solar and wind we can build is funding its high cost alone means going nuclear means far less clean energy, to say nothing of the decades more CO2 output from the coal and gas plants running in the years it would take to build such plants compared to the months it takes for a new solar or wind farm.

  • You realize that even with a laws-of-physics-perfect-theoretical camera in order for a fighter jet to be even a single solitary pixel it would need a primary mirror well over twice as wide as the SpaceX “starship”, right?

    Like launching a keyhole style satellite would require a Sea Dragon just for one pixel per ten by ten meter square.

    I get that space is big and most people really don’t understand scale, but there is a reason that optical spy satellites are well below the ISS in some of the lowest stable orbits for such large satellites, about a hundred and twenty times closer than geostationary to orbit.

    Suffice to say no one has come close to trying this, and it would be the wrong solution to the problem as compared to just throwing 100 times the money to the NRO and letting them throw up keyholes like they were cubesats, and that still would only get you limited areas every few minutes.

    All of this doesn’t effect any of the other problems, like trying to get this imaging down to data centers, doing image recognition on such a massive data stream in near real time, or that it can be completely eliminated in a half hour with a few old fighter jets and some of the anti-satellite missiles everyone down to India has whole stockpiles of.

  • I hate to burst the bubble on the Elon Musk school of ‘what use is stealth when everyone has cameras’ way of thinking, but even neglecting that if you are in a conflict where you are using this sort of fighter jet then your satellites have been shot down by the enemy’s air force, satellite imagery and the laws of physics just doesn’t work that way outside of sifi.

    The planet Earth is just too damn big for that sort of thing. The NEO can give you a decently high res photo of a place maybe several times a day, and even that means prioritizing using said satellite to look at that one single place on Earth.

    More practically you get once or twice a day, with the resolution necessary to pick out a jet being limited to the small area you picked out ahead of time, and of course the enemy knows to within a half and hour or so when that picture is going to be taken.

    AI guided TV missiles have been a thing since the 70s, and still remain only really practical for targets that can’t move very much. Little real world things like size of optics, stability of optics, resolution of optics, atmospheric distortion, cloudy days, night, mountains, horizons, etc, have kept this a non-answer to an unsolved physics problem for quite some time.

    This isn’t to say that the military isn’t an incredibly good way of making public money disappear or that the US has it monitory priorities in order, but rather there is very much a reason that the Inspectors General report into this very project several months ago came back with Yes, this is the most cost effective solution for the military to achieve its goal of providing credible deterrence and preventing a war in the Asia Pacific region.

    Moreover I would argue that the US has never lacked the money for healthcare or schools because of the military, and that if Trump desolved and fired the entire military tomorrow it would still not spend more on schools or healthcare. Rather I would argue that the US is ideologically driven to generally avoid taxing the people with all the money who own its leaders, it by and large does not want that money bring spent on things that benefit poor people, and many of its voters would rather burn the whole thing down than accept a dime going to a black or brown person.

  • It’s worth noting that this project for a F22 replacement has been known to be in development for quite a while now, so this is less a Trump thing than someone at the Pentagon pulling him aside and changing the name to make it less likely he will kill it when Putin or Xi Jinping remember they can just ask him to and he will.

    Here is an excellent as always Perun summery on the US, EU, etc projects as of a month ago, but basically it doesn’t matter how good the F22 is over the pasific if China just shoots down all your tankers and carriers from well out of range, so it’s high time for a pasific range capable fighter.

    Shame it’s going to Boeing though.

  • We may not live in the worst of all possible worlds, but we sure do live in the dumbest.

  • If you want an actually serious answer as to the who, how and why of the assassination and have three hours to spare, I would recommend Sean Munnger (A leftist university professor of modern political history) far to exhaustive series on the topic. For just the CIA, that starts at the 30min mark of Part 2, but builds a bit on previous debunkings.

  • Welcome to the club BYD.

  • Yup, and he also vaccinated his children as soon as they were old enough to qualify. He wants his voters dumb, trapped, and desperate, not his family.

  • I can say that while I near exclusively use the subscriptions feed to start browsing, and will add interesting videos from it to the watch later list, once i’m nearing the end of a video I’ll often choose from the recommended videos on that video rather than going back to the subscriptions page.

  • Tax breaks for the farmers working the fields, or tax breaks for the international corporations and land speculators that own nearly all the fields?

    Possible good news out of Carswell, federal trans inmates may be safe for the time being.

  • From my youtube understanding the 737-800 doesn’t have a RAT, instead using a battery system to power the DC bus, some controls, and minimal avionics. Also for some reason the FDR and CVR are powered only from the AC buses, and so would not have power in a two engine out scenario until the pilots manually started the APU and it came online. It also predates the requirement for said systems to have an independent backup battery.

    This means things are still consistent with a staggered double bird strike or with a single bird strike followed by the pilots shutting down the wrong engine as well as some of the more out there theory’s.

    Investigators might still be able to recover enough switch positions to figure out what happened in the air, but it’s going to be a hard investigation.

    The major takeaway and factor that turned this from a major incident into a catastrophic one however is still that putting the localizer on a concrete reinforced berm for typhoon resistance is a major safety hazard.

  • Yes, the article was generally pretty clear that energy is synonymous with electricity, which is why it’s core thesis that renewables fundamentally cannot replace fossil fuel energy is such a wild assertion.

    Yes we need to provide a decent quality of life, and that can be done with far less than north amarican standards of energy consumption, but the massive increase in energy consumption we’re seeing in India and China arn’t due to western levels of decadence, but rather the proliferation of things like air conditioning in places with fatal heat waves and the like.

    Indeed illustratively these places are known for their abundant, frequent, and highly used mass transit systems and walkable cities. Their energy demand is still growing at an significant pace, not shrinking. As given their sheer size these are the nations which have a far larger impact on climate change, these are the places where degrowth needs to have the largest impact.

    It’s also worth noting that even if you just want to apply degrowth to US cities in the method you suggested, well we know from examples like the Netherlands that it can be done and car centric cities converted into a place with just half of all residents own a car. We also know from that example that it took fifty years of dedicated government support and heavy local support to get that far. Meanwhile even L.A can take a decade and millions of dollars to not build a bus lane.

    To note the obvious, we don’t have 50 years to get the US to moderately decrease emissions, and when accounting for things like construction emissions the gains are pretty small when compared to say electrifying Amaricas railroads or steel foundries.

    This is not to say that things like walkable cities and such arn’t really nice things we should be doing, just that like many degrowth ideas they are both too slow to implement, to marginal an impact, and two specific to certain areas to really move the needle on weather we hit 2C, 2.5C, or 3C.

    This is all of course tangential to the topic we’re actually talking about, which is wether or not electrification and building renewables is pointless when it comes to fighting climate change because they are apparently incapable of ever replacing fossil fuels.
