Airbus seems to get by just fine.

That's true, but the question might be whether you personally should be worried if you find yourself on a 737 Max.

I'm glad we know the cause of the accident now. If the FAA had just explained how severe the consequences would be if someone used a phone on a flight, I think we all would have been more compliant.

The author says "dedicated platforms could provide ballistic missile radar coverage." It doesn't sound like he's suggesting we skip ballistic missile defense.

I agree, but Tesla's charging network actually works, has lots of stations, and charges batteries reasonably quickly. Now that other manufacturers are adopting it, the range issue seems mostly solved, for anyone who doesn't travel

What seems a bit contradictory is that they're also suing because GPT hallucinates about NYTimes articles. So they're complaining that it reproduces articles exactly but also that it doesn't.

I wouldn't say OpenAI has exactly the same attitude, since they also pulled in thousands of books. Their position has been that it's not piracy, since they don't republish the books; effectively the AI just reads them and lea

Tesla's manufacturing has come a long way in the past few years. In 2018, Sandy Munro famously tore down the new Model 3 with a lot of criticism for things like their excess of parts, fasteners, and welds. They made a lot of changes, i

China may be investing in rail but that doesn't seem to be incompatible with BEV adoption. As of 2022, 22% of all new car sales in China were electrics.[1] In the US it was only 6% that year[2], and looks to be about 8% for 2023.[3] [1

Tesla has always cut corners on everything besides the powertrain because batteries were so expensive. Now that battery cost has fallen so much, they're upgrading interiors, starting with the Model 3 refresh. Aside from possibly BYD, o

According to reviews, the refreshed Model 3 has a considerably improved interior. Here's one from Motor Trend: https://www.motortrend.com/reviews/2024-tesla-model-3-highla...

Or to see how difficult it is, which is not difficult at all. Hitting the ground of course is trivial, but you can probably hit a skyscraper the first time you boot up a flight sim. It's hard to imagine anyone doing much "training

For general aviation though, nothing that powerful is available, but you can log training hours on an FAA-certified simulator running the pro version of X-plane.

I'm no expert myself but recently I did see a flight instructor on youtube with the opposite opinion, saying that people with a lot of flight sim experience were his best beginner students, and tended to get their PPL in the fewest hou

X-Plane has a professional version that's used in FAA-certified flight simulators. The home version on a laptop runs the same simulation code. Most flight sim games, including Microsoft's, start with performance data on the airpla

Here's a NYTimes article about six companies attempting laser fusion for power production. At least two have personnel from NIF. One uses an approach similar to NIF's but with modern lasers, and a couple others use a different typ

As you pointed out, it's not veiled at all. And why should it be? We openly spend vast sums on nuclear weapons and people are fine with it. But also, if they already have a weapons research facility and for a little extra money they ca

Of course you're right in general but the fusion triple product actually did increase exponentially, at a faster pace than Moore's Law, from 1970 to 2000. Then for a while everybody decided to put most of the money in a giant cons

Laser efficiency is important if you're actually building a power plant, but for an experimental facility, it's easy enough to correct for the inefficiency of your old lasers. That doesn't make your research inapplicable to p

The situation was unclear for a while, but a few months ago the NRC decided to regulate fusion reactors like particle accelerators and hospital devices, rather than like fission reactors. It was a unanimous decision by the five commissioner

Every dollar we put into fusion could also go into all sorts of things that have nothing to do with renewable energy. For government funding, the money could go to small fission reactors, some military project unrelated to energy, or just a

Worth pointing out that "the part of the branch of the US government that handles nuclear weapons" is the Department of Energy, which of course also handles fusion energy research.

From 0.5% to over 20%, for equivalent lasers. So they still have work to do, but not as much you'd think without accounting for the old lasers.

The startup you link is one of dozens, many of which are pulsed, with several being laser fusion specifically, including Longview, LaserFusionX, Xcimer Energy, Focused Energy, HB11 Energy, and Marvel Fusion.[1] NIF doesn't need politic

However, whatever the situation was before, the DOE recently made fusion power research officially part of their mission. https://www.ans.org/news/article-5611/three-new-inertial-fus...

We openly spend a hundred times as much money on nuclear weapons as we do on fusion research. There's no need for a "cover."
