  • And when people jump to “yeah but Democrats are to blame” I know we’re usually already in Bad Faithville. Both Sides and all that.

    Just no. This is not about both sides in any shape way or form. This is about agency. Fact is: There were ways to do this and the last three Democratic presidents (including the sitting president) have campaigned and outlined plans to codify it into law and didn’t. Yes it may have taken people by surprise that the country and the world is regressing as early and fast as it is, but that doesn’t take away agency, especially when they didn’t even try to spring to action after mere lip service to garner votes.

    The thing is: The conservative, religious right, openly formulated and has been following their plan of judicial activism for decades. The lower courts haven’t become this biased towards Republican policy over night. It was due to bad luck, bad faith acting of McConnel and the other Republican senators and stubberness of some involved people on the other side of the aisle that Trump was able to nominate this many people to the USSC. It would have happened at some point.



  • Hate to be that guy, but it is also the present (hopefully not future) the Democrats have allowed Republicans to build:

    Bill Clinton promised to codify Roe v. Wade into law. He didn’t.

    Obama promised to codify Roe v. Wade into law. He didn’t despite having a super-majority in his first two years.

    Biden promised to codify Roe v. Wade into law and didn’t. The Dobbs decision was taken in June 2022, so before the midterms when Democrats still had a simple majority in the house and a tie + VP in the senate. When there were rumors/leaks a month or so before the decision that the USSC would take that decision soon. Again: Inaction.



  • I would be very surprised if Max hadn’t work shopped the rules with RB to understand exactly what he could and couldn’t do.

    Of course.

    Where I do think he differs is that hes the only one whose repeatedly gone for this grey area and that this grey boundary has been work shopped as an actual stratergy.

    First: I don’t think that this is exactly a grey area, but just a big hole in the regulations. But even, if I grant you that, the questions then become: Why is he the only one? And what would happen if everybody started copying that behaviour? To answer the second question: We are beginning to see this up and down the field. And usually what ensues, is chaos and penalties, because it is impossible to judge the criteria correctly from the cockpit and you need Slow Motion or even Frame Freeze Analysis from different angles to correctly judge it. As for the first question, I offer the following thesis: There is this understanding between drivers even in the lower series (maybe not the very young karting; those are ruthless), an unwritten Gentlemen’s Agreement if you will. And the written rules have become more and more distanced to those principles.

    Lando used Maxs own spells against him

    Exactly the problem (and solution). It is normal that you have to somewhat adjust your driving to your opponent you’re racing. Here, Lando went more aggressive on the brakes. Important to note though: While still making the corner, albeit in a sub-optimal fashion for a chicane with a straight after it. The difference in braking points can be well explained by that line. Max on the other hand went less aggressive than he did before, mainly because Carlos was directly in front of him, before then accelerating and thereby widening his line. I do wonder if Carlos wasn’t there: Would Max have kept his nose in front of Lando at the apex and then maybe even ran wide himself like during the US GP and got away with it? Because them’s the rules? Remember: The penalty for turn 8 was because he overtook outside of track limits, not because he crowded Lando off almost causing a collision and the stewards explicitly note that he would have been entitled to racing room. And for the T12 incident at COTA they write:

    Car 4 was overtaking Car 1 on the outside, but was not level with Car 1 at the apex. Therefore under the Driving Standards Guidelines, Car 4 had lost the “right” to the corner. (…) A 5 second penalty is imposed instead of the 10 second penalty recommended in the guidelines because having committed to the overtaking move on the outside the driver of Car 4 had little alternative other than to leave the track because of the proximity of Car 1 which had also left the track.

    As you can see, the forcing off track is only mitigating for Lando’s lasting advantage penalty, but not in itself a breach of the rules for Max, who wasn’t investigated or even noted for it, although he was only first at the apex because he couldn’t keep it on track himself.

    EDIT: Spelling


  • Agreed, the balance isn’t easy to find, but it’s not a law of nature either. How it has (had?) been handled though, it robs us all of great racing. If you think back to the great duels this year, they weren’t because the drivers all aggressively raced to the apex, forcing off of and risking collisions with other drivers. And then there’s the old story of: imagine if there was grass or gravel out there, I assure you, that they both would have behaved very differently.

    Obviously there’s a difference between being forced off and putting yourself in a silly position where you run out of track

    There’s already the notion, that when locking up for example, then you aren’t fully in control of your car anymore and at least for collisions, that assigns you blame. So one could generalize that.


  • Yes we’ve seen a lot of this. That’s exactly the point. These problems aren’t new and the calls for change aren’t either. In fact, Alonso warned of exactly this behavior and the problems that come with it years ago.

    To the point of allowing a collision to happen, I’m reminded of a somewhat different situation of 2019, but one which should have been a slam dunk penalty: Leclerc forcing off Hamilton in the braking zone of the second chicane in Monza. The implication of the stewards’ reasoning was that because there was no contact, there wasn’t a time penalty. And there was only no contact, because Lewis took to the grass to avoid the collision. So yes, this problem has also existed for a long time and yes, inconsistent ruling makes it only worse. The fact remains though, that under the current regs, you can get away with throwing your car in somewhere and counting on the other driver to avoid a collision.




  • There’s two problems with your last post which have to do with physics.

    1. Fuel Cells and the process of hydrolysis have a limit on their efficiency. Just like with ICEs there isn’t much potential there.
    2. Between Hydrolysis and the Fuel Cell, there are other lossy processes. Usually the tanks contain pressurized H2 and depending on the usecase even liquid H2. Modern automobile cases use 700-800 bars of pressure. That process is again at around 85% efficiency in a good case. Cooling applications further deteriorate the efficiency and need more energy for storage and/or losses during storage. There are other technologies in research right now, like metal hydride storage, where we’ll have to see what exactly they can do (right now we’re at the stage where we are promised an all-purpose hype, but mostly through the media and not the ones doing the work)

    I’m not disputing that capitalism has it’s thumb on the scale; as you’ve written, the synergy to use H2 derived from natural gas is one effect, but it doesn’t stop them from advertising it as green. The physical limits though, one cannot argue with. Their effects would mean a lot more infrastructure that is necessary, with it more materials, which are limited too. Even if possible, we have limited construction capacity, which means that it would take us longer to reach the goal, when time is of the essence. Which leads me to the same conclusion, that where the advantages like power density isn’t absolutely necessary or other solutions are not available, use a better solution.



  • It is not only economic cost though. As I’ve mentioned, materials are also limited (on the same level as: There isn’t enough copper to wire all motors needed to replace all cars today with EVs). And it needs alot of surface area compared to the concentrated power plants of the past, which means an even bigger impact on the biosphere (especially if not done on rooftops in cities but in mountain ranges or fields, etc.). Don’t get me wrong; solar energy, if done right, is the only source that doesn’t interfere with natural cycles and does not increase entropy of the planet (which makes it actually sustainable). Using it inefficiently though, means inefficient use of other resources which are limited. (Not only economic. But on that note: Public infrastructure is always built with costs in mind, because we shouldn’t waste tax money, so we can do a better and more comprehensive job with what we have.)

    So if there is a more efficient way to store energy for long periods, then it should take precedence over a very inefficient one. This will get complex since it is very much dependent on the local conditions such as sunshine, water sources and precipitation, landscape, temperatures, grid infrastructure and much more. As an engineer, I would throw in though, that if you need this secondary storage, that is not much cheaper, doesn’t have some very essential advantage, or doesn’t mitigate some specific risk, but is much more inefficient over your primary storage, then the system’s design is… sub-optimal to put it mildly.

    For the argument of exploring everything: We simply can’t. More precisely we could, but it would need much more time, money and resources to arrive at the goal. And since climate catastrophe is already upon us, we don’t have that time and need to prioritize. Therefore a technology that has a physical, not human-made, efficiency limit loses priority as a main solution. That doesn’t mean, that H2 should not be looked into (for specific purposes, where it is essential or the reuse of existing infrastructure is the better option), but that we have to prioritize different avenues, with which we can take faster strides towards true carbon neutrality.

    P.S. it doesn’t help, that today’s H2 is almost exclusively derived from natural gas.


  • I agree that H2 can have certain applications as a bridge technology in some industries, but there is a very important parameter missing in your premise.

    Even if solar power seems “free” at first glance it really isn’t. It needs infrastructure, e.g. Photovoltaic Panels and lots of it. So just having H2 instead of a battery for an application means, it needs thrice the PV capacity or even more and with it the grid capacity. Now add to that, we aren’t just talking about replacing electricity from fossil fuel plants by PV, but about primary energy as a whole, which makes the endeavor even more massive. Also H2 will not magically become much more energetically efficient in its production, transport, storage and usage, because there are physical limits. (Maybe with bacteria for production) The tech could and should get better concerning longevity of the electrodes for example. Also as the smallest molecule out there, storage will never be completely without losses. And long term storage requires even more energy and/or material.

    All this is to say, that efficiency is still paramount to future energy supply, since also the material is limited or just simply because of costs of infrastructure and its implications on the biosphere. Therefore such inefficient energy carriers as H2 or what people call “e-fuels” should be used only where the enormous power and/or energy density is critical. H2 cars should therefore never be a thing. H2 or e-fuel planes, construction machines or tractors on the other hand could be more appropriate uses.



  • To be fair, business development wasn’t the main hangup for many of the people I know. The two main reasons I heard (and partly raised myself), was firstly the detrimental effect on expanding solar- & wind-energy-production. And secondly overreaching, i.e. not limiting the protection to the environment, but also include townscape protection and historical sites, essentially further restraining residential development (including changing them into more dense usage) in a time where living space is scarce and expensive.

    When the pro-side has its reservations, then of course it doesn’t help that the executive (Federal Council) is dominated by pro-corporate ideology and have brought forward arguments of “damaging the business location”. But making it out to be the only reason is just dishonest.



  • Generally yes, but I believe it is best done on a case by case (meaning type of sports, level and skillset) basis.

    Generally on the recreational level, the differences between the sexes are much smaller than the differences within one sex. The best example that comes to mind is Tennis. Although it is physical in that it requires a lot of high-speed strength, which theoretically should be an advantage (on average) for young men, the skill difference between a man and another is far greater than that between an average man and an average woman. Go to a public court and you’ll see a non-ignorable amount of women outplaying men (if they even dare to play each other) and what’s even more baffling, older people beating younger people. On the absolute elite level though, they seem to almost play a totally different sport. Ball speed, running speed, ball spin and variety in spin on average are very different on the WTA compared to the ATP and therefore similar but different tactics and even technical styles are employed in the two. The difference within the Top 100 ATP or Top 100 WTA is much smaller than the average Top 100 WTA and average Top 100 ATP. So on that level, imho the segregation is merited.

    As some others have already suggested, there might be better criteria to judge this separation on, like with weight class for martial arts. It is not always clear where that divider should be, though. As for tennis: Is it body weight or height? Maybe your fastest or average first serve? Maybe your fastest or average ground stroke? 30m Sprint time? Wherever you put that line might change the nature of the game played in that group and not even eliminate the de facto separation on sex or age, but in turn make it unattractive for some people to engage in a competition in the first place.

    Which comes back to my initial statement of judging it case by case depending on the average difference between sexes and the difference within sexes.

    edit: replaced gender with sex. Didn’t think of it because in my native language this distinction isn’t made.

    As an engineer I can attest that it is also useful for quick calculations and illustrations, especially at the concept stage. We also ran process “simulations” in it for fun, but of course something like SciLab would be better suited for it. The possibility to simultaneously work in the same spreadsheet was also a godsend during lock-downs.


  • I aim to motivate understanding, not assign blame. So I apologize if the tone was a bit aggressive here or there.

    Please understand though, that personal and local experience with something so complex and global is the analogue of using anecdotal evidence to then ignore all quantifiable and statistical evidence. E.g. Because it snows where I live, the planet can’t be warming. Because Aspirin give me nausea, it must be bad… And from that standpoint hurling the accusation of being sheep blindly following some agenda driven group (of which I’m not disputing the existence), well, it’s not very scientific to say the least. And cementing that with that you have done your due diligence with talking to climatologists, and reading articles etc. can lead one to not see this as “just an opinion” but that you add alot of weight to it.

    Please help me understand, how you formed the opinion, that climate change isn’t “a serious concern”. What kind of evidence led you “to different conclusions”? And what suggests the earth be cooling?

    Sidenotes: Science in its essence is a pursuit of objective truth. Politics is not. Neither is the economy. And even if the scientific community faces its challenges, let me illustrate this over the mask issue during the last pandemic. We were faced with a new virus on which we didn’t have data, hence why there were things believed true at first, which got corrected later, when more data was available. Add to that, that mutations changed properties of what we initially had to deal with. Opposed to that are politicians. In more than one country, the health ministers lied intentionally to the people, claiming at first that masks don’t work, because they didn’t want a run on that limited resource due to their failings in preparation. The data didn’t suggest it. When availability improved, we then had mask mandates. It was not because of science, but politics which have to weigh several interests at the same time and where the agenda comes into play.

    Journalists in today’s sensationalist and outrage culture also misrepresent studies to generate clicks. This is why one can get the impression, that studies contradict themselves until one goes to the original text and sees that the claim being made in a news article (probably its title) is mentioned as one, that explicitly cannot be made without further research.
