For low travel areas slower charging and batteries make a lot more sense as the investment in ultra fast charging is not viable and I don’t see that changing

I think regulatory inertia Is always going to be a problem but if we are regularly adding charging stations it will get faster as power companies have an incentive to build them and you get staff trained up on them

Gas stations can still have single point failures for example if their underground tank gets contaminated or damaged and they don’t have a back up and electric doesn’t need to have single point failures you can run them in parallel with breakers able to isolate portions of the system and have redundant transformers

EV works best if most people charge at home/work and people only charge in public if they don’t have the ability to do it at home or they are on a long drive. So you don’t need to meet the same cars per hour as gas stations.

I don’t see a world where fast charging is as cheap as slower charging just due to increased losses and more expensive equipment so I believe having 10 500kw chargers would be a better investment than 6 1MW chargers even though technically the MW chargers have a larger throughput they are more expensive to produce/run and have more issues if for example 8 people arrive at once

Electricity is not my forte so correct me if I’m wrong but if you had a long gap in cars using the charger a capacitor would quickly become saturated. Which means you would need more wattage going to the capacitor at all times. Whereas with a battery if you have a car on a 5 minute charger with 5 minutes in between you could pretty easily run 500kW constantly to the battery and then as the battery dropped in level you could slowly ramp up the power draw

It doesn’t need to be, high voltage transmission lines can run 1000s of MW then you can use a transformer to step the voltage to what you need and then use a rectifier bridge to convert to DC.

The problem I see is the effect of trying to turn on and off 1MW power from a grid could cause problems so the battery could work a bit as an expansion tank to smooth out grid power, so that you always charge it at 100KW and if you need to increase supply you can slowly increase your power draw without shocking the grid.

At the end of the day I personally think 1MW charging is overkill and a 10 minute charge time is a perfectly reasonable goal

It is hard to get a light EV when the batteries themselves are around 1/10 the energy density of gasoline and people want them to have a longer range than a gas car to make up for charging so you end up with a battery that’s 500-1000lbs. To put that into perspective a Miata weighs around 2000lbs

You don’t have to get up because another person gets on, for priority seats they are reserved for those with “special needs” I.e. the elderly or disabled. But it’s common courtesy everywhere to offer your seat to an older/disabled/pregnant passenger.

People should also absolutely be judged for disturbing the peace if you want to talk to your friend on the train you talk in a quiet respectful volume there is no need to talk loud enough everyone around you can hear it.

The Japanese just generally have a respect for rules and for not negatively affecting other people

If you block the radio waves then isn’t that accomplishing the same thing as overloading it with radio waves?

Which will raise weight, costs, and reduce functionality. It’s like a U lock for a bicycle it’s not impenetrable it just raises the bar

There is a huge difference between asking a LLM “ translate the quick brown fox jumped over the lazy dog” and “ write a sentence about a fox and a dog” when you ask it to translate you can get weird translation issues like we saw here but you also get those sometimes with google translate but it shouldn’t change the actual content of the paper

They were translating them not actually writing them like obviously it should have been caught by reviewers but that’s not nearly as bad

It probably is decently common to translate articles using ChatGPT as it is a large language model so that does seem likely

The closest conflicts I have seen is varying codes required and there is usually clear language to use the strictest code. For example one code might require piping with 1/8” thickness if it holds water at X pressure and another will requires 3/16” thickness if that water is going to have a chloride content above X amount so you if it meets both you use the 3/16”.

Except Germany is in a formal treaty with France and the UK who both have nuclear weapons
