As a European those power draws listed sound absolutely absurd to me
Let me clarify - those are standard sized circuits, not actual draw. However the service has to be sized to handle it, and over-provisioning to account for it.a customer might install a stove that draws the full load and might use all the burners at once, and you have to account for typical usage patterns.
For sure it’s a well earned stereotype that Americans use more electricity than many other places. We tend to have bigger houses, more and bigger appliances. We not only don’t have that base charge per size of service but too some extent are charged less to use more: essentially we subsidize people electric resistive heat, who can pay a lower usage rate. We also don’t usually have time of use metering, although some do: my rate is the same whether I charge my car at night or at peak time. And of course our current leadership is intent on rolling back the efficiency standards we have.
Taking your heat pump dryer example, those are finally available here but tend to cost a lot more than a traditional dryer: savings on efficiency will never make back the extra purchase cost More importantly they’ve only been available in small sizes, not typical for houses, especially with families

That may be the entire difference, we don’t have that base cost. Our monthly bill is mainly the actual useage, itemized into generating cost, transfer cost, fees and taxes. There is usually an administrative fee but that’s fixed cost.

- Sometimes breakers don’t trip, so there’s a small risk of fire
- Restarting the whole house may have large initial loads as everything starts at once: more chance of it happening again or potentially damaging some appliances
- Risk of heat damage to wiring with repeated trips, risk of broken connections from more frequent expansion from heat/cool cycles
- Inconvenience, especially in the old days when you’d have to go through to set clocks. If while asleep you might not be awoken in time. If you weren’t home, maybe food gone bad
- Occasional home health appliances are critical to keep going
Realistically it comes down to how conservative you are with over-provisioning. In the US we have the expectation of rarely to never tripping the main and when that happens it’s more likely an electrician call

There’s a standard
- Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26] 1 day ago:
In my experience people get by with a 3x25A (17 kW available, matches approximately a 70A service in the US)
Wow, how do you do that?
Of course over-provisioning is a thing but that’s crazy. Maybe you have much smaller appliances or assume much lower usage, but 70a basically assumes 2 major appliances at a time, using close to max load, and with nothing else turned on.
Typical 240v major appliances
- level 2 EV charger: 50a
- stove: 50a
- central ac: 40a
- dryer: 40a
- heat pump: 50a+
- water heater: 50a
Of course you won’t use them all at once and they won’t usually be drawing their full rated load but I would not want to deal with being limited to one at a time so I can also turn on the lights or use the microwave

I believe dryer outlets are typically 30a@240v. That’s a nice step up than a standard outlet and simple math shows 4x the power of 15a@120v
If you have one in your garage, then you already have an outlet that can do faster charging than a standard outlet.

For me the smart charger was a key feature, and I never understood why that is never talked about. I have 200a service which was plenty for one fully powered charging service, but with the likelihood of electrification in upcoming years I was hesitant to have two. It was pretty clear I needed to prioritize smart charging so I’d have that possibility.
So far my family only has the one EV, so we only need the one charger. But I like that if we needed a second charger it could be on the same circuit and they could dynamically share the power to maximize charging

The way I explained it to my brother:
- technically just plug in to an existing outlet will work. Even if you didn’t keep up every day, you would get tot the weekend and make it up then
- but your garage already has a dryer outlet. Adapters are cheap and it will charge 4-5 times as fast
- but 50a level 2 charger is the same size as a stove outlet. Maybe a little longer wire run, and the “outlet” is more expensive, but it’s well worth the cost for the freedom, the flexibility, the convenience … and may even add to your house value
- Comment on The "standard" car charger is usually overkill—but your electrician might not know that [32:26] 2 days ago:
Agreed, and that headline is needlessly inflammatory . Looking at my mileage , I could almost certainly get away with just plugging into a standard outlet. However the level 2 charger means that even if I screw it up, I can be mostly charged in a couple of hours. It’s been really effective at helping me get over what range anxiety I had. It’s really helped keep car usage as a somewhat impulse thing, rather than a process: I’m ready to go anywhere anytime

Up until that point hp had a stellar engineering reputation. They could have milked that for many more years, but it takes real talent to destroy that so quickly and completely

Counterintuitively, ms phones good reviews were also a good reason for ms to kill it. By the time ms got moving with phones, they were way behind and the market was already consolidating. They had a lot of inertia to overcome. They dumped tons of money into phones, exercised the famous ms marketing arm twisted, pulled out all of their usual tricks … and no one bought them. They ended up with phones that people liked, that got excellent reviews … and no one bought them. Even worse, phones were being sold on the strength of their app stores, and despite sinking tons more money persuading developers to port apps to windows phones, they could never get the critical mass of a sustaining ecosystem. It was pretty clear that even ms would not be able to overcome the consolidation of the market into only two

While I don’t know your situation, this is fairly common in new drivers. For most of us, experience gets us past the issue. Experience to make driving habits automatic rather than something we need to be anxious about. I watched both of my teens get much better at this over time, but I’m still very anxious about them.

The first episode was definitely questionable but once the season got the family out of the way, the fan service out of the way, and discussed on Wednesday, it was much better.
- Comment on How Do I Prepare My Phone for a Protest? 4 days ago:
Yes, very cringey slang for going without protection. Originally from pregnancy or STDs, but now also from boredom. In my case, without the protection of a mask or leaving my wallet and phone at home. I even drove and parked in a local public garage, so would be traceable in several different ways
- Comment on Amazon Doubles Prime Video Ads Per Hour 4 days ago:
The worst are reality show “result” episodes. Seriously, you’re doing a two hour special with extra ads, all about recaps, when the only goal is to announce who won last week?
- Comment on Amazon Doubles Prime Video Ads Per Hour 4 days ago:
I’m was going to say …. I’ve mostly given up on Prime Video but tried to watch it last night and it was intolerable
Netflix too. Even trying to use it according to their rules, they decided my home network is not my home network. I have to keep using the extra authentication, and they are not willing or able to fix it. I’m really just holding out for Wednesday, but maybe I should cancel, and resubscribe in December when I can watch the whole season
I’m not currently frustrated with Disney+, but am also not watching anything there.
I generally try to stay at 2-3 subscriptions but sometimes none of them are worth ot

Jesus Christ, this conversation is scary. I wish y’all good luck that none of these precautions are necessary.
As someone in a blue state where governance is sane, I’m “raw dogging it” (effing offensive slang term but now I’ve used it once in my life and can rest easy) and bringing my kids (teens). M also going to the local demonstration rather than go into the city for a big one - to some extent it’s a numbers game
- Comment on Florida sheriff warns protesters ahead of nationwide rallies: ‘We will kill you dead’ 5 days ago:
Do you really condone over free speech or minor vandalism or self defense? Do you support a police force that skips due process and goes right to murder? Given the situation in LA, and so many more examples of protesting, do you really think they won’t be instigating or faking escalation to murder people
- Comment on [deleted] 1 week ago:
It’s even stupider with the attack on universities. We’ve always benefited from a “brain drain” from other countries where many of the best and brightest come here for an education, and some of them stay.
We’re not just attacking immigrants who make our country great, drive the economy, and offset declining birth rates, but we’re specifically attacking those who might improve science, technology, innovation.
- Comment on The British jet engine that failed in the 'Valley of Death' 1 week ago:
Stop being obtuse. Giving up advancements in science and technology is stagnation. Thinking it’s a good idea to not do anything until people are fed and housed is stagnation. Again, it’s not a zero sum game. Those unfed and unhoused people are not that way because of investments in technology and science, and not doing those things will not affect those people
Focus your nonsense on corruption, exploitation, capitalistic excess, income disparities and most of all elected people with empathy …… that are the cause and could help
- Comment on Shooting an unarmed woman who was just trying to walk home: just LAPD things 1 week ago:
We put too much stock in training here, for things that should be obvious. How do we know you shouldn’t do that? I haven’t had any police training.
This is related to that “qualified immunity” bullshit. Somehow we let what could have been an appropriate thing turn into cops being above the law except in rare cases they were specifically trained for and there is existing case law. Bullshit. All too many of these look interesting headline cases start with “any sane person knows …” yet cops are above the law

But don’t you wish we had status quo now? I could go for a little stability and respect with a side of human rights and investment in the future
- Comment on The British jet engine that failed in the 'Valley of Death' 1 week ago:
I don’t see it as a zero sum game. On the contrary, I see advancing science and technology as an investment in our future that makes it easier to take care of our people, and stagnation as making it harder to care for our people

Sure , there’s always been some deportations. We’ve always patrolled the southern border and arrested and deported people trying to cross illegally. Sometimes it’s less humane than other times.
We’ve also usually granted refugee status to places having a hard time. We’ve usually not worried much about employed people. We’ve usually not kidnapped people from immigration court. Weve usually not had masked thugs terrorizing anyone not white enough.
Elon musk is probably the typical illegal alien. Came here legally on a student visa. Overstayed when it expired, but wasn’t really a problem and no one trying to hunt him down. At some point he caught up on the paperwork. And the economy benefitted.
- Comment on [deleted] 1 week ago:
I’m pretty sure a large number of “illegal” immigrants are those who overstay their student visas or screw up their paperwork. People with a productive life who came here legally.
There’s got to be better way to catch up on paperwork.
- Comment on [deleted] 1 week ago:
Depends on where you’re from. Up in this blue corner I know very few who would support it. Ironically they’re immigrants.
- Comment on The British jet engine that failed in the 'Valley of Death' 1 week ago:
Not at all. The people who are motivated by advancing technology, aren’t motivated to overcome corruption, incline equality, to replace economic systems, etc.
All you’d be doing is stifling innovation, improvement, a reason for hope in the future, for …… the same unmet needs, but now with less hope
- Comment on The British jet engine that failed in the 'Valley of Death' 1 week ago:
That’s not a trade off.
Taking care of people basic needs is not a technology problem or even a resources problem. It’s political, economic, corruption, logistics, whatever variation decides who gets what and how it gets there. We already have the resources and technology to do this
Advanced research projects have no effect on whether the politico-economic system takes care of people’s basic needs. It does, however, help advance society, enhance our capabilities, create new opportunities to improve our lives
- Comment on The Los Angeles Police Department shot an Australian reporter with a rubber bullet while she was live on TV. Zero provocation. 1 week ago:
Even if less-lethal ammunition were risk free, that should still be a crime. Even in the ideal risk-free case, how is this any different from assault, if the cop came up behind a reporter swinging his baton. There was clearly no justifiable reason, it was clearly assault for fun or intimidation, and any reasonable person would know that.
- Comment on ICE thugs pounced on a man right there in the courthouse, mere minutes after his immigration case was dismissed 1 week ago:
While there are way too many who want this cruelty, I have more hope for humanity than that. I have to believe most are low information voters who’ve been manipulated.
I recently had a discussion with my conservative brother, where it was clear that we don’t even live in the same reality. He’s generally a compassionate person, willing to help anyone, but seems to have really bought the narrative. It’s not that he opposes higher education but clearly Harvard is violently antisemitism and the president needs to do something. It’s not that he opposes equal opportunity, but all those DEI hires are taking jobs from people like him. And yes, those deported are all violent criminals (like in my town where masked SS roughed up a city councillor trying to witness the mistreatment of his constituents)
