40 minutes is clearly in the range of doable walks, although if it were a commute I’d do it by bike every time which would shorten it down to 10 minutes, probably.

Is this an American problem that I’m too European to comprehend? If I forget to buy something at the store I literally just walk 4 minutes to the nearest store and buy whatever I forgot. Maybe I’ll even pick it up on the back home on my bike for even less of a time penalty.

The case for an H2 economy is one entirely based on Green H2 made from surplus renewables which are needed most days to have enough renewable energy every day.

Wouldn’t it be more compelling to store it in other types of batteries instead of H2 primarily?

That gas companies know how to build pipelines, distribution, and make metered gas sales to customers is a path for them/employees to remain useful without destroying the planet.

I honestly don’t think H2 is a good idea for these use-cases. H2 distribution is a different beast than natural gas distribution, on top of gas combustion just generally not being particularly good compared to common household electrical counterparts (induction for stoves, electric for ovens, heat pumps for heating buildings and water).

Commercial vehicles has legitimate benefits of lower cost from H2 FCs than batteries. Quicker refuel times. Aviation especially benefits from redesigning planes for H2 for the weight savings. Trains/ships need the power/range. Trucks/cars can use the range extension, and could use H2 as removable auxiliary power for extended range.

I imagine refueling times is not necessarily going to be critical for all types of commercial use-cases.

Aviation struggles with the relatively low energy density in H2.

Trains should essentially always be running on catenaries.

Boats might be able to make use of H2, I’m not super familiar with the issues affecting them.

Long-hail trucking should broadly be replaced by the much more efficient rail shipping.

Cars run pretty much fine on electric as is, I’m not sure the case for making H2 cars is compelling enough to be warranted.

Ammonia and fertilizer is traditional use for H2.

This might be a good niche for H2 to fill.

All in all, I’m still not convinced that large-scale H2 buildouts is a good use of our resources, but there are definitely a few compelling niches that it can fill. We need to be wary of them being co-opted by blue hydrogen fossil fuel companies though, which often seems to be the case today.

I have a generally negative impression of hydrogen because many of the intended use-cases seem to be a cover story for the gas industry to keep existing, which it very much should not be any more.

Do you know any use-cases where hydrogen is truly warranted, outside for example steel production, which I think might be legit?

Americans saw this and then went ahead and voted for the guy anyway.

I hope you realize that this does not go away - it’s enough humiliation to last to the end of time.

Also when you account for those batteries the cost is going to shift a bit.

You better be bringing units if you’re going to be claiming this.

Still less than half of the LCOE of nuclear when storage is added: https://www.statista.com/statistics/1475611/global-levelized-cost-of-energy-components-by-technology/

Given that both solar and storage costs are trending downwards while nuclear is not, this basically kills any argument for nuclear in the future. It’s not viable on its face - renewables + storage is the definitive future.

This claim doesn’t really pass the smell check for me - can you point to where you get the notion from? Checking the lists for average hours worked per year per worker, richer countries routinely have lower numbers than poorer countries.

Encryption is totally and completely haram

I mean, check it out just to rule out the possibility, I guess. The letter spells out how to determine whether this was the case or not - do a hand recount.

76 million, which is not 100s.

Also unironically yes - the time for being polite has passed. Braindead people should be labelled as such in public forums.

As a counterpoint, I’ve bought loads of really good cycling accessories from AliExpress. It’s not impossible to buy high-quality things from China - this is after all where a large part of everything is manufactured these days - you just have to be careful not to fall for the offers that are just obviously too good to be true.

Uncapped overtime excuses bad management. I get why they’re pissed, this puts a spotlight on how bad they are at management.

Is it really valid to call permalink() in that context, since it requires &self? There’s no self in that context afaik. Can’t test it now but it looks suspicious

EDIT: Invalid since the comment was updated

Stopping your finger from bleeding by cutting off the entire arm is not a particularly good plan.

Sure, inflation is down, but the absolute condition for the average argentinian is not strictly speaking great.

It’s clear that some form of change to stop the runaway inflation was needed, but this was not the way to go

Gotta make use of that Force Majeure-clause

Oh fuck that rules

That policy obviously needs to die a horrible death.

Barring some technical breakthrough, I am inclined to agree.

We can and should build extensive high-speed rail networks, though. This will provide intra-continental mobility at a price affordable for everyone. While gratuitous trips to the other side of the world will no longer be feasible, fast intra-continental trips can in many cases take their place. Flying can remain a niche for when it’s completely unavoidable, in which case we should be able to absorb the emissions.
