Those kinds of benefits is what allows Europe to attract talent from across the world. I have lost count of the number of times I’ve heard people who have moved here (northern Europe) say that they couldn’t dream of having kids anywhere els

Did he say “for a given highway range”? EVs are more efficient than ICE, so you gain 2-3x there. Then, if we’re talking city driving ICE is even less efficient unless they’re hybrid or ideally plug-in hybrid, in which case much of the weigh

The kind of LEO satellites that’s being considered here wouldn’t have such a big issue with space debris. In very low earth orbit the orbits decay rapidly, so debris is cleared fairly quickly. And using these low orbits is something SpaceX

Ideally reusable? I think given that SpaceX are now basically guaranteed to provide 100% reusability for the US, anyone trying to keep up, to even remotely match their capabilities, without reusability, will basically bankrupt themselves. I

That argument doesn’t sound very convincing to me. How would I know an avoiding Ubuntu is reasonable? That still seems to be the go-to distro for many people I know that like to use Linux but aren’t Linux experts. How do I know which hardwa

Do you have hard numbers on the tire particle claim? We have anecdotes of Tesla owners saying they go through tires more often. But I’ve also heard car fleet owners with both EVs and ICE saying they see no difference between them. So I’m in

Yet another example where a supposed “gotcha” is simply a good idea. There’s two sides to eating meat: 1: In many cases it’s actually not less efficient than eating a plant. If I eat some lamb or sheep in my area, they’re eating wild stuff

Fiat as opposed to crypto currency? Crypto is the most fiat currency imaginable. I know crypto bros tries to redefine reality to trick people into thinking crypto is somehow tied to real tangible value, but it’s just not. Non-fiat currency

That’s not a given. If the local power plant is owned by a foreign investor, and there isn’t a reasonable tax on the electricity, there’s very little money going into the local economy. Both the mining itself, and many forms of electricity

I don't think air taxis in cities will be particularly beneficial to society, but I think the underlying technology will be very beneficial. It's like the Tesla Roadster. A toy for rich people. But it helped kick-start the EV revo

Apple would want an AI assistant to run locally on your phone. Not to be dependent on sending your data to the cloud to give you results. I don’t see how you think they are behind in general? They’re shipping a fairly powerful neural engine

I gather you haven’t actually read or watched anything from the EV community? Everyone talks about battery durability. BEVs aren’t clean energy. Cars are not energy. They are vehicles. BEVs are fundamentally more sustainable that ICE cars.

Arguably, if they have a limited production rate on this “prototype” - which it seems they do - pricing it so only the ones who are extremely enthusiastic, or ones that will actually develop apps for it and thus consider it an investment, i

I thought so too. It’s pretty simple: if you’re making a nuclear thermal power plant a lot of the costs are associated with building the containment vessel and the heat exchange mechanism. Fusion is fundamentally lower power density than fi

No matter which energy source you use, increasing energy use will eventually cause problems. With nuclear power, eventually you'll add so much waste heat added to the atmosphere that it will be worse than greenhouse gases: If we contin

But PP is one of the plastics that CAN be recycled, and IS recycled, often at a much higher rate than in the US. One of the barriers of effectively recycling PP is the mixing of materials in packaging. I know some brands in my country s

I think what’s missing from Everyday Astronauts discussion is: what if we could make the plane/rocket go much faster. The cruise speed of a jet plane of 800-1000km/h may not be a high enough fraction of orbital velocity to be wort

I didn’t see much discussion on potential efficiency gains in that thread. A launcher would aim for higher altitudes than an airplane, so the question of maintaining efficiency the whole way becomes much more important. I suspect this kind

TSMC now labels their process e.g. “N3”. So there has been a shift away from nm in some contexts. But it really doesn’t matter. There’s not a single physical number you can extract from the process that accurately describes its performance.

Why do you care? Are you designing a standard cell library for it? Seriously. I don’t understand why so many people care that the “nm” number is a marketing term. The chip manufacturing processes are now often improving in ways that measuri

Good points. In the grand scheme of things, I don’t think the CO2 emissions associated with EVs matter at all. Is our goal for to cut emissions by 10%? No. It’s to cut emissions by 100%. To reach that goal, we need all vehicles to be pure

I’m not so sure the comfort criticism is fair with Vision Pro. They seem to think the amount of computer power in this first product is a kind of MVP for their vision of VR/AR. Given this amount of compute with today’s technology, usin

True, but I think we can fall into the trap of expecting too much of LLMs. Their knowledge can seem perfect. They can answer almost anything, so it’s easy to get the illusion that they can answer anything truthfully. In terms of what we can

It would in principle be more efficient to burn oil/gas in a power plant and use some of it to fuel EVs. The CO2 emissions would also be lower. So this isn’t an excuse either. The energy is there, the political willpower is not. EVs ar

You can definitely find a similar metropolitan areas to Oslo in the US. I find Portland to be quite similar. So why don’t they have a similar adoption rate? I don’t see how the “but USA is bigger” means that ALL of USA is completely off the
