    The 2025 Hyundai Ioniq 5 N is the antidote to boring electric cars

    Anecdotally, my family (in the UK, so not sure if they use different engines here) has had two Hyundai i30's in the last 10 years (both parents had one) and both were fine for over 7 years. One was traded in eventually still working fine but is still on the road, the other got traded in, still...

    It’s official: NASA calls on Crew Dragon to rescue the Starliner astronauts

    Pretty much this. If you want to include the risk of Dragon failing catastrophically it starts getting into the realm of also having to mention the chances of the ISS itself catastrophically failing in a way that prevents them getting to a lifeboat and the list starts getting a bit unwieldy...

    NASA likely to significantly delay the launch of Crew 9 due to Starliner issues

    Wait, Just... WTF? Changing the thruster duty cycles is one thing, that was a planned change to try to fix the thruster issues on previous flights (not that it helped much), but... why would you start screwing with one of the software components that did actually work fine!? Surely this goes...

    NZXT wants you to pay up to $169/month to rent a gaming PC

    You know, I've always been told to never buy a computer on credit - save up and buy it all outright. But this actually makes buying a computer on credit look like a good deal? At least if you get a 2K computer on credit paid off over a couple years, once you finish the payments, you still have...

    Cruise failed to disclose disturbing details of self-driving car crash

    Yeah making The Other People die is so much better right? I, personally, do not think self driving cars are this holy grail thats just around the corner, and I don't think sacrificing lives now for some nebulous future benefit makes any sense at all. Thats not to say 'all development should be...

    On its first mission, Astrobotic missed the Moon but learned a lot

    Can I just say that 1: this wasn't just rich people doing it for bragging rights. Among them were scientists and sci fi writers like Gene Roddenbury and Arthur C Clarke who have had massive public inflience on the perception of space and it is in a way fitting that at least a small part of them...

    Getting “forever chemicals” out of drinking water is expensive

    I mean, aiming for a level well below 'we have scientific evidence this is harmful' is usually a good idea for most things. Not always possible, sure, but I can't see any particular reason someone would want to eat more microplastics and PFAS.

    US commits to landing an international astronaut on the Moon

    The moon is a dead pile of rocks in space. If at all possible, better to have industrial activity up there than down here. Nothing up there cares after all. I can understand wanting to 'preserve' the moon and other celestial objects, but if they can help us in some way then why not take...

    Here’s how an off-road racing series will make its own hydrogen fuel

    Of course if you're taking an external source of energy and 'storing' it as Hydrogen then yes that can at least theoretically work, that was never in dispute. My post was a response to a question about why you can't just put water in a hydrogen powered car and have it both drive and electrolyse...

    Here’s how an off-road racing series will make its own hydrogen fuel

    Its a pointless thing to discuss though, because it can't work. It takes 39.4 kilowatt-hours of electricity to get one Kilo of hydrogen from electrolysis at 100% efficiency (which we can't do) One Kilo of hydrogen contains roughly 36 KiloWatt hours of energy. Even with a magic 100% efficient...

    Here’s how an off-road racing series will make its own hydrogen fuel

    Alternators draw from the rotational energy of an ICE engine which is the part you actually want, which means any energy used for this is extra energy on top of what you need to move the vehicle. And putting extra load on the alternator puts more load on the engine, so more fuel consumed

    Here’s how an off-road racing series will make its own hydrogen fuel

    Pipes and seals designed for natural gas will leak Hydrogen like a sieve.

    Here’s how an off-road racing series will make its own hydrogen fuel

    Uh, yeah, that and longevity are why most electric cars already have active cooling for the battery pack. This isn't some expensive and new technology drawing excessive amounts of power. It's a solved problem and its not like racecars needing more robust cooling systems is unknown in the ICE...

    Here’s how an off-road racing series will make its own hydrogen fuel

    I mean, you only have to look at the problems Hydrolox rockets have with leaks to know that storing hydrogen isn't quite that simple. They do get the benefit of not needing to be cryogenic, but Hydrogen will leak and it takes some real engineering to minimise that. Plus, the car still needs a...

    Elon Musk’s AI bot, Grok, speaks as if made by OpenAI in some tests, causing a stir

    Oh now that's just not fair! I mean, you're right about Musk, but Grok is doing a great job standing up for trans rights and roasting Elmo so far, I'd say its doing just fine lol Of course, Elmo is likely to try and have it lobotomised before it angers anymore of the blue checkmark people...

    Hubble back in service after gyro scare—NASA still studying reboost options

    They don't actually use the telescope to track targets you know? Thats why it needs the gyroscopes abd star trackers so it can hold itself in the calculated position commanded from the ground. If a hypothetical guidance tug was equipped with the required accuracy in terms of gyros and star...

    Starlink bug frustrates users: “They don’t have tech support? Just a FAQ? WTF?”

    Err, yeah, not being able to access your account at all after getting a message saying your account has been reset is a big issue The fact the dishes themselves were still working helps nobody when you need to log into the account (which they just disabled) in order to raise a ticket or see if...

    Toyota has built an EV with a fake transmission, and we’ve driven it

    It likely is due to culture, in particular between different parts of the world where automatics haven't quite become the default they way they are in the US. I've driven both, and my current car is a (mild hybrid) Manual , but it certainly doesn't feel old and crummy. And that's likely...

    The UK’s problematic Online Safety Act is now law

    My point is that all this isn't just going to go away when/if the Tories get ousted. Labour might have a different emphasis on which parts they find most important, but they've been pretty heavily behind this bill since it was introduced and those areas they want to be tougher are the only...

    The UK’s problematic Online Safety Act is now law

    All good points, though consider that on this issue at least, the Labour position is that the bill isn't powerful enough. https://www.theguardian.com/technology/2023/jan/01/labour-pledges-toughen-online-safety-bill...
