Comment Re:Wh, not W (Score 1) 46

The useful battery capacity that the owner can get is complicated by the fact that these days batteries are rarely used directly, but rather their output voltage is adjusted via a step up or down converter, often more than once. You can see that with USB power banks, where the actual performance you will get depends on what voltage your phone wants, how much current it pulls, the starting and ending SoC etc.

A single number will never give you a good indication of performance, or even allow for fair comparisons. At least not at the consumer level, obviously engineers who understand all this still need that data.

It's funny how China uses slave labour and doesn't care about safety, pollution, or quality... Until they build nuclear, when they suddenly become the the paragons of safe, clean, ethical energy production.

China is actually a great example of why nuclear is not needed. Their have already cancelled a lot of new reactors because renewables and storage are growing so fast. They just don't need it, and it won't be cost effective.

As for doing away with safety rules and reviews, given that all the accidents we have seen so far could have been avoided by doing those things, it doesn't sound very sensible.

YouTube is mostly not about your friend's videos, it's mostly about people creating professional and semi-professional content for the site.

There is a lot of good stuff on there that you can't get anywhere else. To pick a random example, one of my favourite channels is Adrian's Digital Basement, where he mostly fixes old computer hardware. You get to see him go through the diagnostic and repair process in a way that wouldn't be well conveyed in text, and the videos are very informative for people looking to fix their own gear.

I don't mind paying for YouTube, it's a bit expensive. What I mind is that even if you pay there are still ads.

The problem is that it's impossible to fast track these things. It simply can't be done in the West. And while on paper some of these designs look better than previous ones, in practice what gets built rarely lives up to the hype, and is usually scaled back or an older design to reduce risk and cost.

How is that the worst case? They can still have a full on meltdown and explosions that release large amounts of radioactive material into the environment. The safety systems are better, but not foolproof and not guaranteed to work in all scenarios.

That's why nuclear plants still can't get insurance. The insurers aren't falling for it, they can see that the worst case scenario would bankrupt them.

The cost issue can't be under-estimated though. You can get a lot more renewable energy for the money. Colorado tax payers are going to get fleeced by this.

The other issue not mentioned is speed. It takes so long to build nuclear that it can't be part of any realistic plan to address climate change, and it also makes it very prone to corruption because nothing gets delivered for decades.

Like aeronautical autopilot systems, these are driver aids. They are great in situations like a long cruise down a highway, where they take care of making tiny adjustments to keep the car in the centre of the lane and following the curves, and in stop-start traffic. The same sort of thing pilots use them for - hands off the flight controls, let the autopilot maintain altitude and heading, or follow the glide slope in to land.

The idea with the aircraft systems is that not only is the autopilot very good at those things, it reduces the workload on the pilots so that they can concentrate on monitoring other things, or be more rested and alert when they need to take over.

You make a fair point about the automatic braking though. It depends why it disconnected, it could have been because the driver took over, rather than because it detected a situation that it couldn't cope with.

It's actually really sad how the British government has soiled his name lately, with both the Turing Institute and the Turing Scheme. The latter is our pathetic attempt to replace Erasmus, the EU scheme that allows students to go and study almost anywhere in Europe. It's a poor scheme with limited options and worse terms than the one it is supposed to replace.

And yes, being gay he would have been dismissed as a DEI hire. In fact some places are starting to slide back to the kind of conversion therapy that ended up killing him.

Snow White just isn't a very good story for the 2020s, or maybe ever. On the whole many of their live action remakes have suffered from that. Even younger audiences are a bit more sophisticated now, if you look at popular children's TV shows nowadays.

Snow White, if you look at the actual movie and not the "reviews" on YouTube, wasn't very woke at all. Okay they used a non-white actress, but it's not like the demand for one with lily white skin is saying they should have chosen someone based on their acting ability, is it? And beyond that it's got the dwarfs, it's got a prince and he saves the princess, it's got the usual Disney songs which are apparently better than average for them.

It just became a victim of the culture wars, put in an impossible situation where it could never please either side.
