This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
If the charging speed and range problems are solved (i.e. electric cars charge as fast as normal cars do, on the same schedule normal cars require it) at-home charging becomes a moot point for the same reasons people don't recharge their normal cars in the garage right now. So that requirement is just added expense for zero benefit.
FWIW, Gas stations suck. The ability to home charge an EV daily driver is literally the only reason I would consider getting a near term EV.

It isn't possible.
Consider that the biggest battery you can get on a Tesla Model 3 has a capacity of 100 kWh. They claim it'll do 362 miles on a full charge. Which is indeed nearly as far as small European hatchbacks will generally make it on their 9-gallon tanks, except of course that in the case of the hatchbacks that's the real-world figure and in Tesla's case it's the marketing figure.
If you wanted to charge that battery in six minutes (for easy math), you would need to supply a megawatt of power continuously for those six minutes (in reality even more than that, accounting for losses). Even assuming you could find battery tech that could withstand that, where are you going to get that power? A big, modern, new American house will generally have a 44kW connection (200A at 220v). Charging the one Tesla in 6 minutes works out to the equivalent of the maximum allowed power draw of about 23 houses.
An electric charging station with 10 chargers would need a 10MW grid connection, as much as 227 houses, that is to say as much as a whole neighbourhood. And again, even more, as residential power networks are generally quite a bit undersized on the (for now correct) assumption that not everyone will be drawing the maximum amount all at once.
If you wanted to charge it in three minutes (at which point it would actually approach the time it takes to fill up) you can go and double all of that again.
You've given reasons it wouldn't be possible in a residential setting. But supplying megawatts to commercial charging stations should be quite practical.
Assuming you can figure out a way to deliver megawatts to the battery without melting it or otherwise damaging the vehicle, yes.

Only if we assume that gas station electricity per kwh will be lower than the one in the outlet at home. And the time it takes to charge is also free. Because I have a habbit to always start a journey with the tank full - those 20-sh minute detour to charge at the begging or end of trip are quite annoying - the 15 min breaks in the middle of the trips are not bad. So I could see the value. And anyway american homes consumes more and more electricity and are still stuck with feeble 110v outlets that can't deliver 2kw, using a hack (two phases ) to get something decent, so it is nigh time to update that part. I have often expressed desire to bump the power in EU homes to 7-10kw at the breaker.

I'd assume the reason people don't do that is because they don't have gasoline piped into their houses. If I did I absolutely would never visit a gas station again if I could help it.
