The US really doesn't understand that there is simply no competing with these batteries. To try to block the import of them is only going to set our own local industry back in their ability to compete in the global economy. And ironically the BMS systems for CATL are still using American semiconductors, so the US still gets some revenue from their massive expansion.

The most viable competitors to CATL are all in China too. I'd be somewhat supportive of a CATL specific ban due to their notoriously terrible employee working conditions and crazy NDAs/non-competes, but to ban all Chinese batteries in the US would be a huge mistake.

The problem is that this isn't really even trickle charging. Customers would absolutely complain and say it's not working because it couldn't charge the battery more than 1-2% in an entire day of sun. EV batteries are 60kWh+ yet getting more than 2kWh/sq meter daily from residential panels is hard for much of the US. Add to that the:

  • weight of panels
  • cost of panels
  • heat trapped in the car from having a roof literally designed to absorb solar radiation
  • fragility of panels (although all these glass roof EVs have that problem already)
    And it's really not worthwhile.

One solution to the apartment street parking problem is adding charging ports to streetlights (they do this in Europe). But for most of US apartments there's already dedicated parking space so also space for chargers. The unruly size of new vehicles is a much bigger problem in my mind, if there were actual motivation to fix this problem in government it would already be solved through some tax credits.

New outlook is less functional but much better UI design (it's just outlook web access after all). Outlook hasn't changed in forever because so many corporate high ups use it and think they know how it works. They always respond to emails that are already answered because they didn't see the newer reply in their inbox. I suspect this resistance is why it's a totally separate program to the old outlook. Yes, there are settings to group threads in outlook, but the interface is still pretty unintuitive and the vast majority of these users don't change their default settings anyway. In my experience the terrible defaults create more problems than outlook solves. And the server syncing can be really slow at times. Personally, I'm very happy that MS is finally showing some interest to modernize outlook, the more people who use it the easier my job will get.

Also ya the name is stupid. Teams (New) gets me the most. Idk who possibly thought this naming scheme was a good idea.

They take pork products particularly seriously. At least on their flag carrier, China Airlines, it would be incredibly hard to ignore the video played prior to landing with the talking pigs specifically pointing this out.

Almost no countries allow meat products due to potential exposure that couldn't be easily seen. Sometimes for commercially prepared meats there are exceptions but these are in relatively few countries. For countries with substantial livestock keeping diseases out is critical to their economy and therefore treated with such a high level of urgency.

Yep, and the Chevy Silverado EV manages 200kWh now. This cargo ship better be small and efficient because 250 American pickup trucks worth of battery really isn't much.

It's still not a lot of energy though. Some rough napkin math for how far this would get you is below:

Typical medium size cargo ships in the Panama Canal travel around 25 knots burning 63000 gallons per day of fuel with 5000TEU of cargo. That's roughly 600mi/63000gal or 1142miles per ton gallon. That Silverado EV somehow weighs 4 tons (totally safe to be driving at highway speeds), so this is the equivalent of roughly 285.5mpg per Silverado. The Silverado is 67mpge on its own, so the ship is just over 4x as efficient (and slower which is ignored here but would impact the vehicle efficiency).

So using the Silverado's 450 mile optimal range we can say it has at most an optimistic 7 gallons equivalent fuel in its 200kWh battery. 50 MWH would be enough for a theoretical 1750 gallons equivalent if efficiency were the same. But for the efficiency difference this corresponds to a 4.2x improvement to 7350 gallons equivalent. Therefore this is enough to run that typical ship above for 2.8 hours. So with 65000 tons of cargo in the above ship to do a 200 mile route this ship would need roughly 3x as large a battery. More likely it will just carry ~1/3 the cargo or have charging stops en-route.

The 19.4km/h top speed of this ship suggests they're well aware of the extremely limited range this will have for its size and it sounds like the Shanghai to Nanjing route will be pushing it's limits despite being less than 200 miles.

True but efficiency is not the same and not as simple to compare since we don't know how much of the ship's battery is converted into motion. Similarly we don't directly know it's mass. ICE cars can use ~20% of the energy in fuel while EVs 90%+ of the energy in a battery. But now much can that ship effectively use? I have no idea how efficient boats are or aren't, hence the roundabout method above.
