  • VW is good at making cars, but bad at software. They’ve had to delay the introduction of new models (Golf, ID.3) because of software issues. Rivian has sort of the opposite problem: their production lines sit still often because of problems in the supply chain.

    Volkswagen has the expertise to solve Rivian’s production and supplier problems, and the cash they will need to survive and develop some cheaper models (the EV market is stagnating right now for a lack of budget options, and Rivian only sells trucks and SUVs). And they’re hoping Rivian software engineers can help them fix their software woes.




  • Honestly, I think it may be possible to build entire roads with enough crushed metal elements in the asphalt/concrete and a slight low power charge throughout the entire surface would be able to keep any vehicle battery at a steady charge.

    You might be underestimating how much power a car consumes while driving. For example, a Tesla model 3 has an efficiency of about 130 Wh/km in mild weather at highway speeds. Assuming that on the highway you’ll travel 100 km/h, that means you’ll use 130*100 = 13.000 Wh/h, a constant power draw of 13kW. That’s enough to power perhaps 8-12 houses on average.

    A km of road could have, let’s say, 200 cars on it (4 lanes, 20m per car). That means you’d need to pump about 2.6 megawatts of power into every kilometer of road to keep them all topped up.

    EDIT: fucked up math




  • Andrea Dworkin was an influential feminist mainly in the '80 and '90. She was pretty clearly anti pornography, at least as it existed in her time (she died in 2005. Who knows what she might think of some of the stuff out there today). She’s also one of the most frequently misquoted feminists of all time, particularly by anti-feminists. she did not say all heterosexual intercourse was rape:

    Several reviewers accused you of saying that all intercourse was rape. I haven’t found a hint of that anywhere in the book. Is that what you are saying?

    Andrea Dworkin: No, I wasn’t saying that and I didn’t say that, then or ever. There is a long section in Right-Wing Women on intercourse in marriage. My point was that as long as the law allows statutory exemption for a husband from rape charges, no married woman has legal protection from rape. I also argued, based on a reading of our laws, that marriage mandated intercourse—it was compulsory, part of the marriage contract. Under the circumstances, I said, it was impossible to view sexual intercourse in marriage as the free act of a free woman. I said that when we look at sexual liberation and the law, we need to look not only at which sexual acts are forbidden, but which are compelled.

    The whole issue of intercourse as this culture’s penultimate expression of male dominance became more and more interesting to me. In Intercourse I decided to approach the subject as a social practice, material reality. This may be my history, but I think the social explanation of the “all sex is rape” slander is different and probably simple. Most men and a good number of women experience sexual pleasure in inequality. Since the paradigm for sex has been one of conquest, possession, and violation, I think many men believe they need an unfair advantage, which at its extreme would be called rape. I don’t think they need it. I think both intercourse and sexual pleasure can and will survive equality.

    It’s important to say, too, that the pornographers, especially Playboy, have published the “all sex is rape” slander repeatedly over the years, and it’s been taken up by others like Time who, when challenged, cannot cite a source in my work.



  • All well and good, but the term dictatorship here still refers to a situation where the state apparatus has complete control over the means of production, in other words a total centralisation of power. Indeed in Marxism-Leninism the dictatorship takes the form of a vanguard party forming a single party state. Whichever way you look at it, practical power resides with a very small group of individuals.

    The contrast with the eventual stateless communist society, in which power would be completely decentralised, is quite striking. It’s not quite clear to me how Marxist-Leninist theory envisioned the transition from one to the other, although it seems to me there was a general feeling that central economic planning and industrialization would fairly quickly lead to the end of scarcity altogether, which in hindsight seems… very optimistic.

    If you ask me, the ideals of communism mostly died around the same time as Lenin. Pretty much all communist states that have existed (and currently exist) are mainly interested in maintaining their own power structures rather than actually working their way towards the idealised communist society. Which pretty much just makes them dictatorships in the classical sense.












  • That doesn’t mean energy has a weight.

    No, it literally does mean that. If you put light in a box of mirrors the total weight of the box will literally increase by an amount equal to the energy of the photons. If you put some radioactive material in a theoretically perfectly sealed box from which no heat or light could escape, and weigh it while it decays into radiation, the weight will not change.

    This applies to all forms of energy. A spring is heavier when compressed. An object gets heavier when you spin it, or heat it up. Sunlight hitting the earth most definitely makes it heavier. In fact, the sun hits the earth with about 4.4*10^16 watts of power, corresponding to about 0.5 kilogram per second.
