If it is indeed easy to move operations wholesale, I think we would see far more and quicker cases (not just arbitraging differences in labor organization, but also e.g. tax and regulatory regimes). It certainly happens, mind you, but my read is that different forms of institutional inertia puts a damper on the willingness to "re-home".


You're right about driver time being the key metric. mattlondon's reply[1] to the GP gives the extra context: the endurance is aligned pretty well with (EU) legally mandated breaks, allowing for mid-day charging.

Edit: I see you've replied there.


Which might be OK in Europe. My current area allows for 13 hours of driving during a maximum 14-hour work day. Most semi drivers then maintain a 14+10 rotation for a few days before a "weekend" of downtime. These Volvo trucks are nowhere near that sort of daily endurance and just wouldn't be competitive.


Yes, it's clearly a problem that in some places poor working conditions, risks in road safety due to fatigue and global warming due to fossil fuel use are found acceptable because it allows companies make more profit.


Nobody is arguing these trucks can currently cover every single use case. The US long distance trucking industry is an outlier.


Yeah, in the US they should probably run overhead wires which would be more efficient than batteries. They could also consider coupling together a few dozen trucks on the highway. For the ultimate in efficiency, and to reduce particulate emissions, they could replace the wheels with steel wheels and make them run on tracks...


Running overhead wires cross country in the US would be exorbitantly expensive. In the city? Sure, though it would be ugly. In the countryside, not a chance of it being workable.


You don't need it in the city or in the countryside, you just need it on the highways. The overhead wires will directly power the cross-country legs, a small battery can cover last-mile delivery and interruptions in overhead wire coverage due to things like complex highway interchanges.

Besides, it's not like this kind of electrification is unheard of. Most of the world has electrified rail with a density higher than the US highway system, and India has been electrifying its railways at a pace of over 4000 miles per year. Electrifying the main cross-country freight corridors by the end of the decade should be quite doable.


Electrifying railways seems easier than doing it to the US Interstate, since the railways control what goes on their tracks. The US has roughly 50K miles of Interstate highway. From what a cursory search showed, electrifying rail is roughly $1m/mile. So it would cost at least $50B to electrify, not to mention converting the semi trucks to use it. Considering how much of a hot topic EVs and alternative energy sources are, this is a non-starter in our current political climate.

And forgetting the practical components, the highways would look really bad with wires overhead...


Who said anything about long haul? A longer workday doesn't mean a longer route. Most trucks do multiple deliveries every day without ever leaving their home area, commonly between ports and warehouses.


> Who said anything about long haul?

You did, just above:

>>>>> It isnt about travel distances. Most "long haul" trucks ...

With 5,000 of these trucks sold, and presumably others from other manufacturers, maybe just accept your personal experience isn't universal.


That's screwed up. How's the accident rate in your area?

I can't imagine it's possible for people to keep up their attention and stay alert for multiple consecutive 14hr days


Methanol has been used, as has rubbing alcohol and methyl ethyl ketone. https://en.wikipedia.org/wiki/Denatured_alcohol for further reading.

https://en.wikipedia.org/wiki/Denatonium is used to make it unpalatable. Fun fact: the same chemical is also coated onto Nintendo Switch cartridges to discourage children from putting them in their mouths.


We used to use denatonium (Bitrex) in firefighting to test the efficacy of your face mask seal - you'd put on your mask, a filter, and a hood - Bitrex would be aerosolized into the hood and if you could taste it, there was not a good seal.

Nowadays we just measure pressure differentials.


Have you checked out mixbox[0]? The outputs do feel intuitively "right" as someone who has dabbled in watercolor, and the paper/videos cover the thinking and Kubelka-Munk theory well.

Spectral.js might also be interesting. It comes with a GLSL implementation of Kubelka-Munk and is MIT.

Wild! Just saw that at the top of the front page and thought ‘dang is HN reading my mind today??’

Thanks for the link!


oh wow, they have the fluid demo too!!! Thats so much better!

Jay Leno has a Doble car (mentioned in the article as a 1920s attempt at a "user-friendly" steam car revival). The video has great production and really shows the starting and driving processes: https://youtu.be/rUg_ukBwsyo


There's at least one commercial acoustic underwater modem provider - Subnero out of Singapore. They claim up to 5km range:

> 4 km of communication range (horizontal) in littoral waters

Probably much lower range vertically.


> The typical efficiency of TEGs is around 5–8%

A steam turbine is many times more efficient.


But it has way more parts... And it moves. This other path has no moving parts.


Scania did a neat affordance for this in their (otherwise rather incremental) autonomous AXL concept. A band of LEDs around the vehicle that light up "towards" a pedestrian once the vehicle takes them into account: https://youtu.be/0WN9xvAvEls?t=499


The explanation is right there in the article, and it does not involve your supposed modern day hubris:

Restorers found that the central panel of the artwork, known as the Adoration of the Mystic Lamb, had been painted over in the 16th Century.

Another artist had altered the Lamb of God, a symbol for Jesus depicted at the centre of the panel.

Now conservationists have stripped away the overpaint, revealing the lamb's "intense gaze" and "large frontal eyes".


The article is not about general infertility in couples.

It is specifically about male infertility, based on an objective measure of fertility (sperm count), which has indeed dropped over the past few decades - no one is trying to "blame everything on men".
