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

The argument the person was saying is that we already have big bombs that do catastrophic damage, the R&D is how do you make those bombs more targeted so they have less collateral damage.

Now whether that will actually lead to less deaths or will just cause the bombs to be used in places they otherwise wouldn’t be used with the same amount of collateral damage is unknown.

But it brings up a bit of a utilitarian dilemma of “is it ethical to work on weapons if it leads to an overall reduction of collateral damage to civilians”

It doesn’t have a necessarily correct answer

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?

Dihydrogen monoxide is old news what you really have to be worried about is hydric acid!! It’s a solvent that is used heavily in the chemical industry and they want to place it on our fruits and vegetables

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

They are notorious for going into small towns and undercutting local businesses until they go out of business then raise prices, they also severely underpay employees. And the owners are the wealthiest family in the world who use their money to lobby for right wing policies

I try small brick and mortar as much as possible but the up charges for the identical product can really hurt, like why is the same brand of pet food twice the cost if I drive 10 miles for it vs if I order it online

Is Walmart really any better than Amazon?

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”.

Isn’t like more than half that number diseases like malaria spread through mosquitoes

This is very low in the world of government overreach. It doesn’t stop restaurants from having reservations, it doesn’t stop 3rd party companies from coordinating the reservations, it doesn’t even stop charging for reservations… all it does is stop 3rd party companies selling reservations from a restaurant without their consent.

These companies add nothing of value to consumers or restaurants and seek to harm both as they increase the cost of getting a reservation and cause people to have a certain disdain for the restaurant.

Sure the restaurants could make the process of getting reservations harder and more expensive with regular audits and authentications but this is literally what the government is for, nobody is harmed with these laws except scalpers

You need to amend the constitution which requires 38 states to agree to it that considering how many right wing states hate California doesn’t sound impossible

The civil war only happens if the U.S. attacks after a secession, but the state that single most funds the U.S. military is California, if you include Washington and Oregon in the secession you now end up with 19ish% of the countries budget and a sizable percentage of the military bases. With the American civil war there was somewhat defined lines of north vs south but this would be fights inside their own states.

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