My parents are retired fire-fighters. They had an American pygmy goat named Bleve. Those goats commonly have very rotund stomachs[1] that look like they are about to explode.
A BLEVE does not need oxygen to become an explosion. The explosion occurs with the rupture of a tank (that has been heated, increasing the internal pressure and thus increasing the boiling point of the liquid inside, so that it remains liquid). This causes a loss of rapid loss of pressure, which in turn rapidly decreases the boiling point of the liquid, thus causing a sizable part of the liquid to almost immediately boil and cause an expanding "cloud" of gas.
When this occurs, you have an explosion that can propel parts of a steel propane tank up to 1/2 mile (at least).
It doesn't need it but it makes it that much more destructive. Your propane example is such a case - as the hot cloud expands explosively it burns on contact with new oxygen and the heat serves to further perpetuate the process. An overheated tank of propane provides an illustration of the principle on which thermobaric warheads are based.
Legacy car manufacturers have done just that (forcing an EV into an ICE chassis). The results generally suck and the pure EV manufacturers like Tesla and BYD have kicked their ass in the market.
You can use a similar design to your existing fleet without a literal retrofit of an existing chassis to shoehorn a battery and electric drive train in there.
The retrofits usually are less preferable not only because of pointless inconveniences like transmission tunnels, but because they'll be the manufacturer's first toe dipped into the EV waters. The retrofit chassis speaks to either a rush to market, or a cautious approach not wanting to commit too many resources. The former says it'll have issues, the latter says they might bail on it and leave you stranded for service and repairs. Or both at once.
That was kinda different thing. It was legacy manufacturers scrambling to push out any EV they could get together so they are not left behind too much. But in meantime they started working on genuinely new designs (like Hyundai Ioniq, Mercedes EQS, BMW Neueu Klasse) or they adjusted their platforms to better accommodate electric drive trains (like Audi e-tron).
Driving manual/stick is considered "manly" and a lot of sports car enthusiasts would never drive an automatic. So I presume this multilevel "torque language" bullshit is basically a way to retrofit stick shift into an EV that has no mechanical need for it.
Agreed, I'm driving a ~2000kg truck atm with a stick shift from the 90s and a V8 in a hilly city and it's so much more fun than the arbitrary compact cars I've been borrowing for years. Super mega scary on gas, but fun nonetheless as on occasional leisure thing.
I've never heard of this, but it looks incredible. I've seen some similar looking beasts around that seem to be modified for apocalypse survival and would love to try and drive it, as long as I don't have to reverse it up a slope lol
This is a bit out of date. These days basically any ATM allows foreign cards, just in time for Japan to finally switch to electronic payments in a big way (in particular PayPay).
Yes. The payments landscape has shifted pretty dramatically in Japan over just the past 3 years. It used to be that you had to worry about getting cash, IC cards, refilling said IC cards, going to an actual bank with your passport, etc. Now all you need is an iPhone (although I hear Android phones from outside Japan still can't use suica).
I was in Japan recently and did find that my non-Japanese Pixel phone wasn't allowed to use the mobile Suica app, even though the hardware supports it. Some nerds on XDA figured out the mechanism preventing it[0], and if you're rooted it seems like you can run a Magisk module to patch the region check in the PixelNfc component[1].
I guess it's down to licensing for the FeliCa smart card system or something? I will say, as a privacy person, I'm pretty jealous of the ubiquity of IC card payments there. You can buy the card at a kiosk with zero KYC and top it up with cash at the same kiosk. Since it's a stored-value system, it works offline, and you get the convenience of paying with a card with nearly all of the anonymity of paying with cash.
Given that my friends with iPhones were having more trouble than me with a visitor Suica, the phone advantage isn't a major one.
Also, non-Tokyo transit systems often support VISA tap and pay.
A visitor Suica card (that you can buy at the airport and refill with cash in seconds), a VISA, and cash (that you can get at any ATM with a debit card) is 100% sufficient for travel in Japan.

The cash part of it is non-negotiable, though. Many merchants are cash-only. Presumably, handling large amounts of cash works fine in a society where the risk of getting robbed at gunpoint is actually zero [1], and where the police are ready to use very persuasive methods to maintain that 99% conviction rate.
---
The real frustration is that buying rail tickets online inevitably triggers an extra layer of VISA verification (2fa code through SMS or email), which usually works fine, but has already shat the bed for me once, requiring a chat with my card's CS rep. Which fucking sucks when you don't have a phone # that works.

[1] While the risk of some cutpurse ganking your wallet is so near-zero, it's a rounding error.
This will remain the case as long as Sony continues to charge Android manufacturers heavy licensing fees for the FeliCa chip needed for Suica/Pasmo.
However, major Japanese cities are increasingly allowing credit card tap to pay for transport, Osaka Metro is already 100% on board and Tokyo has started trials. There's a long tail of minor companies that will likely take forever though.
Tokyo Metro, Toei, Keikyu, and others have rolled it out across a significant chunk of their lines at this point.
You can get to a significant portion of the network... So long as you don't have to take a JR train.
My only complaints about Contactless Cards from Visa/Mastercard/etc. Is that they're significantly slower than FeliCa. I can sprint through a gate with my Pasmo; I have to stop with my Visa.
For Visa, the closest transaction processing happens in Colorado. So they're slooooooow.
Disclaimer: Fmr Visa, current PayPay employee. I hate payments.
Android doesn't support suica for public transport but you can still use Google Pay most of the time. Except when you randomly can't! Unlike other countries you still need to take a credit card (and maybe even some cash) as backup.
Android does support suica/felica, and many (most?) phones have the hardware for it, but most manufacturers will only pay the licensing fees for it for their Japanese SKUs, leaving other SKUs with a software lock.
"Unlike other countries you still need to take a credit card (and maybe even some cash) as backup"
"still"
I take a reliable CC and cash any fucking day over Apple and Google Pay or any shit payment "app" like Revolut which simply blocks you out of your account if on a device they seem to not like / that is not attested, while preventing browser-based usage.
You stupid tech bros. Appps, apps, apps, everything via an app.
Even the Tokio metro paper tickets via cash work well. No phone needed!
My wife has a US-bought iPhone, and we tried to load some money onto a digital Suica card. The hardware is there, but the system wouldn't accept any of the credit cards or her debit card that she had registered with Apple Pay.
An Indian friend of mine (who lives in the US) told me it's similar to when he visits family in India; none of the digital transit cards work for him because the system won't accept his US payment cards.
(I have an Android phone which has the right FeliCa hardware, but it's disabled in software so Google doesn't have to pay the licensing for it.)
Visa and (to an extent) Mastercard have been known to block transactions from their foreign-issued credit cards to digital Suica and PASMO cards. US issued Amex and Discover cards (at least prior to the latter's acquisition by Capital One) use JCB's merchant network in Japan, and thus receive the same treatment as any other JCB-branded card.
There are still significant gaps. I was heading from Narita to Shinjuku about a year ago, and after I got off the Narita Express, I realized my Pasmo card (which I hadn't used in about 8 years) didn't have enough on it to get me the rest of the way. There were two ATMs I could find in the (reasonably-sizeable) train station, and neither accepted my US-issued VISA debit card. I had to walk down the street to -- of course -- a 7-Eleven to use the ATM there.
During the rest of my week and a half there, I saw plenty of other ATMs that appeared identical to the ones in the train station that didn't work for me.
> These days basically any ATM allows foreign cards
I thought so, too, and perhaps it's just bad luck, but I was at Tokyo Station a few months ago, and I wasn't able to withdraw cash from Mizuho Bank's -- one of the largest retail bank in Japan -- ATM from my US debit card. I ended up walking (getting lost for) ~10 minutes to a Seven Bank ATM, and withdrew cash there without issue. So YMMV.
ATMs from the major banks (SMBC, Mizuho, Yuucho, etc.) are still extremely picky about supporting US cards. Most will do it... for an egregious fee.
Kombini ATMs are better about this, but 7Bank ATMs remain the gold standard with no fees outside of whatever the bank itself charges. LawsonBank is OK, but few/far between. Enet (at a lot of kombinis) are terrible.
There is a lot of money in NYC-LHR, that's why Concorde continued to fly that route and profitably too, once they realized how high they could yank the prices and still fill the plane.
Also, Concorde's maximum range was 4,488 mi, which was calibrated to allow trans-Atlantic but not much more. Trans-Pac was not an option and even Australia to North Asia would be a stretch.
There is money in NYC-LHR (it brings BA alone $1B in revenue annually) but the market for supersonic basically vanished. In the 70s when Concorde started flying, it was certainly a step up. However, the market niche basically disappeared when the lie flat seat was developed; for a lot cheaper, you could have a sleep for six hours in a really cushy lie flat, or you could spend a crapton more to be in a much louder, more cramped cabin for only about three hours less. If you were halving a 12-16 hour journey instead, there would still be a market left, but Concorde just didn't have the ability to do so.
You can also essentially work remotely in an airplane now. I haven’t tried videoconferencing, but I easily do all my other software work on trips. So a couple extra hours might even be a benefit: more time with no distractions to wrap up that slide deck, maybe a 1:1 or two, get your free drinks from premium/business class, doze off to a movie, wake up for an early start at your destination.
Shorter, no, but having a private cabin with a shower, and a lounge with a bartender on the plane, not to mention Starlink, would make those 12 hours a lot more bearable vs 12 in an economy seat.
AFAIK: Showers are only available to first class customers flying via the major Gulf carriers. I checked Google flights for business class and first class tickets between Tokyo and London. Business is about 5,000 USD and first class is about 10,000 USD. Assuming that we are talking about first class here (to satisfy your shower requirement), what kind of developer is hacking code at 10,000 meters in first class... except... hmm... Mitchell Hashimoto?
Mitchell Hashimoto's got tres commas in his bank account and his own jet. He doesn't need to take commerical, or even first class. If we backsolve, say $10,000 is a once a month purchase, and $10,000 for a hotel and you stay a month. Say your other living expenses are $10,000/month, so we're shooting for spending $20,000/month. With the recommended shaving off 3% the nest egg, (20,000 * 12) / 3% gets us $8 million in the bank.
So at $8 million in the bank, you could take a $10,000 plane trip, stay for a month, spend $10,000 on a hotel, take a $10,000 flight back. Still upper end of net worth, but nowhere near Mitchell Hashimoto territory.
For context: the author is George "geohot" Hotz, who has a long list of exploits, likely the best known of which is basically vibe coding (I mean that in the nicest possible way) comma.ai for autonomous cars on a shoestring budget long before actual AI vibe coding was a thing.
Are you serious? They just launched a completely revamped version of Starship from an entirely new pad, and still hit almost all of their planned milestones while demonstrating that the design is reliable enough to handle a missing engine.
Two successful test missions over 15 years using a dead end rocket and ship design for $50+ billion is not something to be proud of either.
Starship's design is so far beyond where the rest of the world is that even if it takes another 3 years of iteration to perfect it will still be by far the best rocket in the world for many years afterward, to the point where it would hardly make sense to choose to launch on any other existing or currently in development rocket for any reason other than political ones.
