Show me how the capital costs of rolling out high PSI hydrogen infra will be cheaper than building a power grid. You can even refit and re-use existing natural gas pipelines to move hydrogen if you want to cheat. I am willing to bet the costs per kW will still be crazy, especially at last mile where you are in an area populated by humans.
I don't see a bright future for hydrogen in transport while we keep putting cheap solar, wind, and batteries on the grid / roads.
Yeah. Vehicle costs are pretty much the same (for battery electric and fuel cell electric buses, at least) and are about 2-3x more than ICE. On-site hydrogen infra for fueling/storage is substantially more than charging equipment. H2 fuel is currently $10-20 per kg (the higher end accounts for vapor losses), which is, again, much greater than either diesel or electricity.
Replying to myself. I just read the article. The gray/blue/green H2 fuel costs in the article do not reflect current U.S. fuel costs.
Gray is $8-10 for liquid delivery. This equates to a little over $1 per mile, which - compared to a CNG bus - is double the operating cost (and about 4x more than a battery electric bus per mile... just for fuel/electricity). And yeah, as I mentioned previously, capital costs will be like 1.3x of battery electric.
That said, there are lots of novel ideas out there for creating H2 fuel! Forest waste (with supposedly all carbon captured), methane pyrolysis (with carbon bricks as an output). The promises never end.

If only there was budget somewhere else under DHS’ purview they could spend on TSA…
Having tried different systems since the days of Evernote, the _only_ thing that is consistently useful like obsidian is... emailing myself whatever info I have to look up later. I even used to do this for reminders.
Google search in Gmail continues to just work.
But also I want something better than email, so I've been a happy obsidian user for a while now.
This is America. Our toilets use _clean potable water_ to flush our shit.
Drinking water from the mains is metered, so it is observable from the business perspective. Life finds a way. Heat exchangers and datacenter plumbing absolutely breed life and put things into the water that were not there when it was pumped in.
Imagine if a datacenter used a shady supplier of pipe that used, say, lead in their alloy. Do you want that datacenter grey water going into crops?
Do you think that water that the water that flows from kitchen sink and water that flushes in the toilet in normal house/apartment come from different pipes in any other place of the world?
The water from the lake isn't drinking water either, it is contaminated with all sort of stuff including dead animals and animals excrements. But it doesn't mean it is not suitable for agriculture.
What Anthropic has done here seems rooted in Buddhist philosophy from where I sit.
Being compassionate to The User sometimes means a figurative wrist slap for trying to do something stupid or dangerous. You don't slap the user all the time, either.
If you want to use your hands and collaborate with humans a lot in person, the trades seem to be quite exciting right now. Salaries are also good — A good plumber in our area makes nearly $800/hr, and that's not touching what the datacenter plumbing folks are making.
That's still quite good either way, but OP should understand that even in most expensive US cities a journeyman plumber is typically pulling at most like $150k-$200k without doing significant overtime. And you won't get there until 5++ years on the job.
So think more like $100/hr of actual compensation on the higher end.
Not a bad gig at all. But that $800 number comes with a lot of caveats.
With 10 yrs experience and taking travel jobs to remote locations you MIGHT break $100 hr without OT. With North Slope experience you can get jobs that are paying ~70 with guaranteed OT so like you will crack $100 /hr but that's working winter in Alaska. Even offshore jobs aren't paying $100. No one is paying 800.
My side gig pays around that, but there aren't many hours involved it in, and there isn't a good opportunity to find more hours, so it isn't all that much money at the end of the year. It is a tidy job for the effort required, but you wouldn't want to have to live off its income.
Not a typo. The good plumbers bill by $180-200 per 15 minutes. If they are independent, they take all of that home. If they are part of a larger company, they are still pocketing a significant portion of that billing depending on how the plumbing company operates.
The most advanced ASML machines also cost something like $300-400M each and I am willing to bet if configured wrong can heavily damage themselves and the building they are in.
And they announced the next version of the Lightning last month. People don't like that it isn't purely BEV, but I don't see the big deal.
Unlike a traditional hybrid, the F-150 Lightning EREV is propelled 100
percent by electric motors. This ensures owners get the pure EV driving
experience they love — including rapid acceleration and quiet operation —
while eliminating the need to stop and charge during long-distance towing.
