It is actually less dangerous than other fuels, for the simple reason that it is extremely light and buoyant. A gasoline fire is bad, because the gasoline stays where it is until it fully burns. A hydrogen fire is less bad, because it will tend to move upwards.
That's assuming the hydrogen is just loose in the area, like it'd been released from a balloon in a chemistry classroom. That amount of hydrogen is extremely small, from an energy standpoint. Equivalent to a teaspoon of gasoline or so.
If you assume a realistic fuel capacity for a hydrogen vehicle, the hydrogen tank will be both much larger than a gas tank and the hydrogen will be under extreme pressure. A tank like that in your car would be extremely dangerous even if it were filled only with inert gas.
Hydrogen mixed with air has a very wide range of concentrations where it is explosive. It accumulates inside containers or just the roof of the car… where the passengers are. It takes just one lit cigarette for it to go boom.
There was some beef the site owner had with Cloudflare where if your were using Cloudflare DNS it wouldn’t serve anything to you? Is that still happening?
Not sure why it would only be on archive.is and not the others but ‘is’ loads for me.
I expect that to go about as well as Facebook changing their name to Meta and putting all their eggs in the Metaverse/VR basket...
But at least Meta's legacy businesses (Facebook, Instagram, WhatsApp) were still valuable enough to fall back on - whereas Tesla's seems to be tanking. Only their utility-scale fixed battery business seems to have much potential if they can't turn around their dwindling car business.
Yes, hard to see how LLM agents won't destroy all online spaces unless they all go behind closed doors with some kind of physical verification of human-ness (like needing a real-world meetup with another member or something before being admitted).
Even if 99.999% of the population deploy them responsibly, it only takes a handful of trolls (or well-meaning but very misguided people) to flood every comment section, forum, open source project, etc. with far more crap than any maintainer can ever handle...
I guess I can be glad I got to experience a bit more than 20 years of the pre-LLM internet, but damn it's sad thinking about where things are going to go now.
Argentina has debt in foreign denominated bonds though - the US (and UK, Japan, Canada, Australia, NZ, etc.) don't, only issuing bonds in their own currency, which makes a massive difference.
Not to say that Trump isn't wreaking economic havoc and madness, but the USD is resting on a far stronger base than somewhere like Argentina.
> A large portion, maybe even the majority, of travelers simply won't feel safe without it.
Nonsense. Most of that is just because it’s been normalised - because it exists and the people manning it make such a song and dance about it. Going from that to nothing would freak some people out, but if it were just gradually pared back bit by bit people wouldn’t need it anymore.
Here in Australia there’s no security for a lot of regional routes (think like turboprop (dash-8) kind of routes) starting from small airports, because it’s very expensive to have the equipment and personnel at all these small airports, and on a risk-benefit analysis the risk isn’t high enough. Some people are surprised boarding with no security, but then they’re like, “Oh, well must be OK then I guess or they wouldn’t let us do it”…
We also don’t have any liquid limits at all for domestic flights, and don’t have e to take our shoes off to go through security domestically or internationally, and funnily enough we aren’t all nervous wrecks travelling.
For context, at the moment they hope to have them operating some time in the 2030s. That’s a best case, just like the cost estimates (which operating practically and safely may be more than what people are forecasting)
Not operating today like it sounds from the comment.
The idea isn’t great, tunnels for cars or pods have really low throughput (low occupancy + safety margin headways, even at a high speed). And it hinged on them magically revolutionising an already highly mature field, which surprise, surprise didn’t work out.
If it had been possible to speed up and reduce the cost of tunneling, the thing that would most make sense is running regular trains through them. But they never had any real ideas to actually make it cheaper or faster (apart for making it too small for proper emergency egress), just the idea that SV tech guys would be able to find a way to do it.
I disagree, tunnels for transport of both people and goods, especially in high-density urban areas is the best way to go. Walking and biking is great for their distance, but cars and trucks are still needed for larger and heavier items. Using shared transportation (like a train) is terrible for "The last mile". Doing everything at night just seems like a band-aid and sucks for all those workers.
The idea of trying to solve the hard infrastructure problem of digging first also seems like a great idea. Build the aqueduct before you build the millions of houses and farms, and even let anyone do that part.
It's still premature to say that they haven't revolutionized the field, people around the world are still digging tunnels so there's still a market. It wouldn't be the first time an already highly mature field got revolutionized, I still don't get why you're so anti-tunnel.
Here is the thing, you demand incredibly high amounts of capital cost for not actually achieving much. And that capital could be use for far, far, far, far more useful things the city actually needs. Like high capacity transports, like metros, trams or bike lanes.
The amount of goods that need to be transported to stores and such things isn't that big. And using literally free unused roads at night or early in the morning is just a great deal.
For individual transport last mile is regularly being done by cargo bike or small electric truck just fine.
But you are right, tunnels do make sense for some things. Like transporting garbage underground. Or transporting heat underground for district heating, or district cooling. Both would be better investments then trying to move logistics under-ground.
There is a reason, no serious attempt anywhere in the world is trying to move logistics under-ground. There are just so, so many better ways to invest in the city. Its literally not even in the Top 100 most needed things.
Specially in the US where the road network is so hilariously overbuilt that it could serve 10x the amount of people on the same area if public transport was just taken minimally serious. And in the US, underground cargo transport isn't even in the Top 1000 things a city should consider spending money on.
There’s only so much gridlock you can avoid without going above or below grade. I was shocked when I moved to Seattle and they had no subway system. It was made even worse by being crammed up against a tall hill with a ridiculously deep lake behind it. They are finally changing it now but I’d spent time in Tokyo before, and time in London and Paris shortly after and it was a real head scratcher. One bus tunnel helped, as was evidenced when they shut it down for a couple years, but cmon.
Because The Boring Company hasn't built any tunnels worth noting, perhaps, and stalled most of its projects.
This isn't a case against tunnels, this is a case against The Boring Company.
The tunnels aren't a great idea apriori. Good luck pitching the tunnels idea in Venice.
The tunnels may be a good or a bad idea depending on many variables, and the tunnels that the Boring Company has actually built are worthless.
As for the tunneling equipment: selling those machines isn't their core business, and there's no evidence these machines have, or may in the feasible future, do anything revolutionary in the tunnel industry (i.e., built radically better, radically cheaper, or radically faster).
The idea of having such machines is good. They don't have such machines.
> It's still premature to say that they haven't revolutionized the field
It's never premature to say that. Read what you wrote.
You can say a field has been revolutionized once a revolution takes place.
It's hasn't.
The impact of the Boring company on the way tunnels are dug is, very sharply, zero.
Is it possible that they will? Sure. It's also possible that Britney Spears will. She still has the time, it's premature to say she wouldn't do it, right?
That’s a cop-out though. Company boards are legally required to act in the best interests of shareholders, and plenty of shareholders would agree that running a business in a sustainable way that can deliver profits over the long term is more in their interests than a business trading its future for some short term profits.
It’s a cultural problem really, where too many people who study business and economics have been taught this idea that it’s a moral necessity that businesses maximise profit for shareholders (to the point where plenty of people even wrongly believe that’s a legal requirement!), but it’s an ideological position that has only caused once great companies to fail and huge damage to our economies.
